Note
• Spread restricted to Level I nodes carries better prognosis
• Spread to Level II has poor prognosis
• Spread to Level III indicates worst prognosis
Axillary tail of the Spence: It is the extension of the upper outer quadrant of breast across foramen Langer deep to deep fascia. Foramen Langer is an opening in deep fascia over outer aspect of the breast which allows part of breast tissue to extend under deep fascia,
otherwise rest all breast tissue is in subcutaneous plane. Axillary tail is located adjacent to outer border of the pectoralis major muscle. When it is involved by carcinoma it should be differentiated by pectoral node enlargement. Axillary tail will move along with main breast tissue whereas pectoral node will not move when breast is moved as it has got independent mobility. Axillary tail often extends over the lateral edge of the pectoralis major muscle up to axilla (Figs 16.34A and B).

SRB’s Clinical Surgery
Fixed enlarged axillary nodes can cause lymph­oedema due to lymphatic block; venous thrombosis and venous oedema due to venous block; and severe excruciating pain along the distribution of the median and ulnar nerves (rare in radial nerve) with often significant sensory and motor deficits due to tumour infiltration of the cords of brachial plexus (usually medial cord occasionally lateral cord).
Examination of arms for venous oedema or lymphoedema: V enous oedema may be due to axillary
vein compression by nodal mass. Lymphoedema may be due to lymphatic block following nodal involve­ment. Lymphoedema is mainly distal. It is gradual in onset and progressive. Venous oedema is sudden in onset, with bluish discolouration over the skin, uniform in both distal and proximal aspect of the upper limb (forearm and arm).
Examination for mediastinal node involvement: It is done by percussion. Initially percus for liver dullness. Percussion is done one space above from lateral to medial, to look for widened mediastinal border . Media­stinal nodes are common in middle mediastinum.
Examination of respiratory system: It is done for secondaries—altered breath sounds, features of consolidation or pleural effusion are looked for (Fig.
16.35).
Fig. 16.36: Always examine abdomen for liver enlargement, ascites or Krukenberg tumour (in premenopausal age).
Examination of abdomen: To look for palpable nodular liver, Krukenberg tumours in ovaries in menstruating age group, and ascites. It is completed with digital examination of rectum (P/R), and per vaginal examination (Fig. 16.36).
Examination of pelvis, spine, long bones for any swelling/tenderness/pathological fracture/restricted
movements of spine, hips, etc. Examination of central nervous system to look for
any neurological deficits following metastatic disease in the brain.
Fig. 16.35: Look for pleural effusion and altered
breath sounds for secondaries in lungs.
Breast self examination (BSE) has got a major role in early detection of the carcinoma breast.
Ideally done once a month, just after the menstruation, as during this time breasts are less engorged. In postmenopausal age group it is done regularly at monthly intervals (fixed day of the month).
• Examine both breasts
• American cancer society recommends monthly BSE after 20 years of age
• Remind the patient that 90% of breast lumps are not cancer
• Better way is in lying down position with arm raised with a mattress support behind (Fig. 16.37)
• Palpation is done over all quadrants of the breast using the fingers
• If any doubtful swelling is palpable, consult the surgeon
• Nursing mother should perform BSE just after feeding the baby.
Assessment of nipple deviation: Nipple changes are assessed by inspection, palpation and measurement. Displacement of nipple is assessed by measuring

Causes of massive enlargement of breast
• Benign hypertrophy usually bilateral
• Giant fibroadenoma (> 5 cm)
• Serocystic disease of Brodie
• Sarcoma
• Carcinoma often when extensively involved
• Filariasis of breast.
Causes of hard swellings in the breast
• Carcinoma breast

• Traumatic fat necrosis
• Calcified haematoma
• Fibroadenoma—hard variety.
Investigations in Carcinoma Breast/ Breast Lump
Mammography
It is plain X-ray of soft tissue of breast using low voltage and high amperage X-rays (300 MV and 40 KV). T wo

pictures showing microcalcification, spiculations and irregu­larity.
films are taken—Craniocaudal from above downward; mediolateral from side-to-side. Dose of radiation is
0.1 cGy, a low dose. So it is a safe and effective procedure (Figs 16.38A and B).
Findings
• Microcalcifications/branching calcification signify
malignancy
• Soft tissue shadow may be smooth and regular in
benign conditions or irregular in carcinomas
• Size and location of mass lesion is assessed with nipple
and skin change (thickness)
• Spiculations; mammary duct distortion; loss of
symmetry; clustering; architectural distortion suggests carcinoma.
Breast Imaging Reporting and Data System (BI-RADS) has got its own categories (0-5), assessment and recommendations. Digital mammography is compu­terised electronic image of the breast with enhanced magnified pictures. Digital spot-view mammography allows faster and more accurate stereotactic biopsy.
Indications for mammography: For screening purpose it is done after 40 years. Early screening is indicated
384

when there is family H/o carcinoma breast or histological risk factor. Mammography before 25 years of age is usually not done unless there is a lump or a strong family history or suspicious lump; in obese patients; to find out spread or de novo tumour in the opposite breast; mastalgias; mammography guided biopsy can be done; evaluation and follow up in benign breast disease with malignant potential; follow up mammography after conservative breast surgery. Grading of lesions in mammography: Grade I: Negative; Grade II: Benign lesion; Grade III: Probably benign lesion: Grade IV: Suspicious of malignancy; Grade V : Highly suggestive of carcinoma; Grade VI: Known carcinoma.
Digital mammography is better to analyse and store the pictures.
Xeromammography is same as above, but here a photoconductor is used to produce a final image on a Selenium paper (on aluminium plate) rather than on X-ray film. Such charged plate is placed behind the breast and X-ray exposure is done. Selenium positive charges are released, which depends on X-ray traversing the plate and the tissue. Electrostatic image of the breast produced is made blue by spraying negatively charged blue toner on the plate which attracts image of positive charges. This blue image of breast in a special coated plastic paper is fused permanently using heat. Advantages: Edge enhance­ment effect, therefore useful in dense breasts. Disadvantage: Exposure to high radiation dose and selenium plate is needed. Mammography of excised specimen may be useful in identifying the exact site of small lesion for histological assessment.
Contrast mammography often can be done by injecting water soluble iodine dye into the major lactiferous duct. Duct papilloma may show smooth filling defect; duct carcinoma shows irregular filling defect.
The condition when lump is clinically not palpable but mammogram shows identifiable carcinoma is ideal for breast conservative surgery like quadrantectomy/ QUART therapy.
Ultrasound of Breast
It is done to look for lesion whether solid or cystic, margin of the lesion, internal echoes, retrotumour acoustic shadowing, compressibility, dimensions.
SRB’s Clinical Surgery
Irregular mar gin, irregular internal echoes, irr egular posterior shadowing, non-compressibility, ratio between anteroposterior to width (lateral/horizontal) dimensions more than 1 ar e the features of carcinoma.
Doppler will show high frequency signals with continuous flow . Benign lesions are smooth, rounded with well defined margins with weak internal echoes and compressibility . Disadvantage is lesions less than 1 cm may not be identified. FNAC can be done under US guidance. It is cheaper, easily available and there is no risk of radiation. It is preferred method of screening in pregnancy and early lactation (Fig. 16.39).
Fig. 16.39: US left breast showing fibroadenoma.
FNAC (Fine-Needle Aspiration Cytology)
FNAC is very useful in diagnosing the carcinoma breast. FNAC is also done under US guidance. But negative results are difficult to interpret because it may be due to sampling errors and so requires further diagnostic methods. FNAC of opposite breast, lymph nodes, opposite axillary lymph nodes are also often required. It is done with 23 gauge needle using FNAC aspiration special syringe. With the lump held firmly , the needle is passed into the lump and with negative pressure continuous aspiration is done until adequate material comes through the needle. Needle with syringe is removed without negative pressure. Material is collected on a slide; a smear is made using 100% alcohol. Cytology is studied after staining it under microscopy. After FNAC, cystic swelling often disappears completely . Excision may be indicated, if it recurs rapidly after two aspirations, and if FNAC is inconclusive (Fig. 16.40).

Fig. 16.40: FNAC of breast lump.
Advantages of FNAC: FNAC is least painful, can be done on OP basis, reliable and cheaper. Malignant deposits will not occur along FNAC track (only contraindication for FNAC is testicular tumour). FNNAC is Fine Needle Non-Aspirating Cytology. FNAC scoring: C0 – no epithelial cells; C1 – scanty epithelial cells; C2 – benign cells; C3 – atypical cells; C4 – suspicious cells; C5 – malignant cells.

Frozen Section Biopsy
If FNAC fails even after two trials or in cases of negative FNAC, then on table frozen section biopsy is done for diagnosis. It has got 20% false negative results. It is often difficult to differentiate between severe atypia and carcinoma by frozen section and so its validity and use is under debate. In such situation excision biopsy is better . While doing excision biopsy incision is placed in such a way that it can be included in eventual mastectomy. Trucut/core biopsy is also used nowadays in many centres.
Chest X-ray: T o look for pleural effusion, cannon ball secondaries in lungs, mediastinal lymph nodes, secondaries in rib. CT chest is mor e r eliable method to see lung secondaries.
Ultrasound abdomen: T o look for liver secondaries, ascites, and ‘Krukenberg’ tumour.
X-ray spine or MRI spine/pelvis shows osteolytic secondaries in the bone like vertebra and pelvic bones.
Radioisotope bone scan is done to look for secondaries in bone in advanced cases. It is not done routinely

tissue. It is an important indicator of prognosis of carcinoma breast. Tissue for receptor study is sent in low temperature in ice flasks. It is assessed by quantitative analysis (Frozen –70°). If value is more than 10 units (Femtomoles) per ng gram tissue it is called as ER +ve status. If value is 5-9 it is borderline and if it is less than 5 femtomoles per nanogram tissue it is called as ER –ve status. In ER +ve status— Prognosis is good; Hormone therapy including Tamoxifen is very beneficial; Response to treatment is better. In ER –ve status—Prognosis is poor; Hormone therapy is not very beneficial (but used) as compared to ER +ve patients; Response to treatment is not good. ER positivity is common in postmeno­pausal women (60%) compared to premenopausal women (30%). Progesterone r eceptor (P R staus) study and Her 2 Neu receptor status are other studies done at present to plan the therapy and assess the prognosis.
Study of Discharge from the Nipple
Nipple discharge is usually unilateral in carcinoma breast. Ductal lavage may be useful in some patients. Microcatheter of 1 cm length is introduced gently into the ductal opening. 10 ml saline is infused through the catheter. Fluid is withdrawn into the syringe and cytological analysis is done.
MRI of Breast and MRI of Spine (in case of suspected spine secondaries)
It is done—to differentiate scar from recurrence; to image breasts of women with implants; to evaluate the axilla and recurrent disease. Both precontrast and postcontrast MRI are done. T
and T2-weighed images

are taken. Irregular mass with spiculations, changes in skin and nipple, lymphoedema are the findings in carcinoma breast (Fig. 16.42).
Edge Biopsy
Edge biopsy is done only when there is skin involve­ment—ulceration and fungation. Diathermy should be avoided in incision biopsy as it may distort the histology of tumour and study of hormone receptor status may not be possible.
Tumour Markers
They are used mainly during follow up period. CA 15/3 is commonly done when needed.

Sentinel Lymph Node Biopsy (SLNB)
being carcinoma breast.
The first axillary (SLN) node draining the breast (by direct drainage) is designated as the sentinel node. SLN is first node involved by tumour cells and presence or absence of its histological involvement, when assessed will give a predictive idea about the further spread of tumour to other nodes. Involvement of other nodes without SLN is less than 3% and so if SLNB is negative nodal dissection can be avoided but regular follow up is needed. SLNB is done in all cases of early breast cancers, T1 and T2 without clinically palpable node. It is not done in clinically palpable axillary node as there is already distortion of lymphatic flow due to tumour. It is also not done in multifocal and multicentric tumours, as there is involvement of many lymphatic trunks from different quadrants of breast, chances of false negative is high. Sentinel node is localised by preoperative (within 12 hours) or per­operative injection of patent blue (Isosulfan vital blue dye) or

visually as blue staining or with a hand held gamma camera; and is biopsied with a small incision directly over it. If there is no involvement of sentinel node by tumour then further axillary dissection is not required as skip lesions (skipping sentinel node) occur only in less than 3% cases. Note: Facility for SLNB is not available in many centres (Fig. 16.43).
SLNB is done in—
• Carcinoma breast
• Carcinoma penis
• Malignant melanoma.
Axillary sampling is often done with an adequate axillary incision. 10-15 nodes are removed for sampling. It is not commonly practiced now (Minimum 10 nodes should be removed—level I nodes).
CT scan of chest, abdomen and brain whenever
needed. CT is said to be more useful to detect secondaries in these regions.
Triple assessment—It includes (1) Clinical
assessment; (2) Radiological imaging (US in young, mammography in adult; (3) Cytological (FNAC) or histological analysis (core biopsy).
Ductography
It is contrast study of ducts of breast in case of unilateral nipple discharge. Fine cannula is passed under vision carefully through the duct opening into the duct and
0.2 ml of dilute water-soluble contrast media is injected
387
into the duct. Craniocaudal and mediolateral X-ray films are taken. Contrast irregular filling defect may be observed.
Thermography is not very sensitive test (50%).
Malignant tumours are hypervascular and so transmitted temperature is detected through different thermographic methods. It is the pictorial represen­tation of infrared emission of breast.
Biochemical analysis: Increased serum alkaline phosphatase, γ glutamyl transaminase suggests liver secondaries. Raise in urinary hydroxyproline means collagen breakdown suggesting secondaries. A low value of urinary aetiocholanolone, a metabolite of adrenal dehydroepiandrosterone in relation to total 17 hydroxycorticosteroids (in urine) is specific of breast carcinoma suggesting poor prognosis and poor response to adrenalectomy and hypophysectomy (Poor discriminants).
Newer modalities of investigations: Stereotactic core biopsy using computer mammography; vacuum assisted biopsy using 11 gauge biopsy probe; needle localised biopsy under mammographic guidance; I

localisation biopsy.
Differential Diagnosis
Carcinoma Breast
How carcinoma breast is suspected?
Any lump in the breast can be malignant unless proved otherwise. But one has to remember that every breast lump need not be always malignant. Short duration, rapid progression, nodal status, hard consistency, with often irregular surface and late features like fixity to chest wall, ulceration/fungation and distant spread are the features to consider for carcinoma breast. Painless
lump with irregular surface and stony har d consistency
are typical features of carcinoma breast.
One has to remember that differential diagnosis
for carcinoma breast is same as all conditions which are benign diseases of the breast (Table 16.1).
Table 16.1: Differential diagnosis for carcinoma
• Fibroadenosis • Mastitis
• Traumatic fat necrosis • Antibioma
• Tuberculosis of breast • Galactocele
• Bloodgood cyst • Mondor’s disease
• Filariasis breast • Cystosarcoma phylloides

SRB’s Clinical Surgery
Aetiology: Carcinoma breast is more common in developed western countries. In African-American women, it is more aggressive. It is less common in Japan. It is second most common carcinoma in females. Incidence is 19-34%. Median age is 47 years. It is more common after middle age, but do can occur at any age group after 20. It is familial in 2-5% cases. Carcinoma in one breast increases the risk of developing carcinoma on opposite breast by 3-4 times. Incidence of bilateral carcinoma is 2 %. Diet low with phytoestrogens and high alcohol intake may predispose carcinoma. It is common in nulliparous women. Early child bearing and breastfeeding reduces the incidence of malignancy. Breast carcinoma is directly related to oestrogen level increase. Early menarche and late menopause has got higher risk probably due to increased oestrogen level. It is more common in obese patient. Breast cancer relative risk is qualified as Relative Risk (RR). RR 2.0 means risk is twice the normal population. If RR is 0.5 means risk is 50% less than normal population. In males, occasionally gynaecomastia turns into carcinoma. Benign breast diseases with atypia, hyperplasia and epitheliosis have got higher risk in a patient with family history of carcinoma breast; mutation of tumour suppressor genes BRCA 1 and BRCA 2 has also shown high risk of carcinoma breast. BRCA 1 has got more risk (35-45%). It is located in long arm of chromosome 17. It is also associated with ovarian carcinoma. It is poorly diffe­rentiated, ductal invasive, hormone receptor negative type carcinoma BRCA2 is located in long arm of chromosome 13. It is well-differentiated, invasive, positive hormone receptor type carcinoma. It is also associated with carcinoma male breast. Occasionally mutation of BRCA3 and p53 suppressor gene is also involved. Cowden’s syndrome and Li-Fraumen’s syndrome are associated with carcinoma breast. Presently carcinoma breast is considered as systemic disease. Her 2 neu mutation (transmembrane growth factor) is seen in 80% invasive ductal carcinoma;
carries poor prognosis. Halsted concept of spread is sequential spread. Breast—axillary lymph node— systemic spread. Fischer concept is early to begin with itself, there is possibility of distant blood spread because of micro metastasis without nodal disease. Only tumour lesser than 1 cm size can be sequential. Spectrum concept is new one where disease spreads locoregionally as well as systemically which makes it to have both locoregional as well as systemic disease control. Prior diagnosis of uterine/ovarian/colonic cancers increases the risk of breast cancer. Endocrine cause is considered as ‘Koreman’s hypothesis’. It means, anovulatory cycle which is more common in early menarche and late menopause with unopposed estrogen without progesterone; hyperprolactinaemia due to late child birth (which is inhibited in early child birth); oral contraceptives; absent breastfeeding; hormone replacement therapy; all predisposes carci­noma breast. Carcinoma breast shows geographical variation with very less incidence in Japan.
Incidences in carcinoma breast
• 30% of all female cancers
• 20% of cancer related deaths in females
• 2-4% bilateral
• 2-5% hereditary
• Familial breast cancer – 25%
• Sporadic breast cancer 70%
• Lump in the breast-commonest presentation (75%)
• 10% presents with pain
• 35-45% with mutation of BRCA1 gene
• 70% blood spread occurs to bones

b. Invasive—invasion through basement
membrane—80%.
Invasive ductal carcinoma—70%.
Invasive lobular carcinoma. It is commonly multifocal and often bilateral. It is 10-15%.
III. Unilateral.
Bilateral: 2-5% common.
IV. Unifocal.
Multifocal. Multifocal—tumour tissues within the same quadrant. Multicentric—tumour tissues within the breast but in different quadrant.
Duct carcinoma in situ (DCIS): It is intraductal carcinoma without any invasion into the basement membrane. It is 5-20% common. It can be—Solid; Comedo with necrosis is high grade with increased chances of microinvasion; Cribriform; Papillary, Micropapillary. It is associated with high expression of C – erb2 gene (80%). Nipple discharge and often­small swelling are main presentations. US assisted FNAC and mammography are the needed investiga­tions.
Risk of lymph node spread in DCIS is less than
4%. So axillary dissection is not necessary.
Sentinel Lymph Node Biopsy and later required surgical procedure is the preferred method (if facility is available).
Pathological Types
Scirrhous carcinoma: It is 60% common. It is hard, whitish, or whitish yellow, noncapsulated, irregular, with gritty, cartilaginous consistency. It contains malignant cells with fibrous stroma.
Medullary carcinoma: It is also called as ‘encephaloid type’ because of its brain-like consistency. It contains malignant cells with dispersed lymphocytes. It is 4-10% common; occurs in younger age group; associated with BRCA 1 hereditary cancers; it is soft and often haemorrhagic; it carries better prognosis than scirrhous type.
Inflammatory carcinoma/lactating carcinoma/ Mastitis carcinomatosis: It is 2% common; it is
common in lactating women or pregnancy; it mimics acute mastitis because of its short duration, pain, warmth and tenderness. Clinically, it is rapidly progressive tumour of short duration, often involving whole of breast tissue with occurrence of Peau`d orange, often extending to the skin of chest wall also. It rapidly metastasizes to chest wall, bone and lungs. It is always stage IV carcinoma. FNAC confirms the diagnosis—It contains undifferentiated cells. It mimics acute mastitis but total count is normal in inflammatory carcinoma of breast.

SRB’s Clinical Surgery
Colloid carcinoma (2%): It produces abundant mucin;
common in elderly; presents as bulky tumour; positive for oestrogen receptors.
Paget’s disease of the nipple: It is superficial manifestation of an intraductal carcinoma. The malignancy spreads within the duct up to the skin of the nipple and down into the substance of the breast. It mimics eczema of nipple and areola. In Paget’s disease, there will be a hard nodule just underneath the areola, which later ulcerates and also causes destruction of nipple. Histologically it contains large, ovoid, clear Paget’ s cells with malignant features (Figs
16.44 and 16.45). Tubular (2%), Papillar y (2%), Cribriform are the other
types of duct carcinomas. Papillary carcinoma occurs

Fig. 16.45: Subareolar carcinoma with destruction of
nipple-areolar complex.
in late age group – 7th decade; small tumour of less than 3 cm; carries good prognosis. Tubular also carries very good prognosis.
Atrophic scirrhous carcinoma: It is seen in elderly females. It is a slow growing tumour which has got better prognosis.
Lobular carcinoma in situ: It is predominantly pre­menopausal; need not be detected by mammography; it is an incidental pathological entity; multifocal and bilateral; clinically, it does not form a lump; does predispose to invasive cancer; 50% cancers can develop in the contralateral breast; immunohisto­chemistry using cadherin antibody shows positive reaction; it carries poor prognosis.
Disease of Reclus: It is rare intracystic papilliferous carcinoma of breast presenting as a cystic swelling with bloody discharge from the nipple.
Presently invasive breast cancer is classified as ductal and lobular. 70% are invasive breast cancers. It can be infiltrating ductal carcinoma not otherwise specified (NOS); tubular (2%); colloid (2%); medul­lary (basal like, triple negative means ER/PR/Her 2 neu negative, aggressive, 5%).
