New methods to fight cancer

Cancer treatment is constantly evolving. Some of these methods are now accepted therapy, and others are under investigation and are experimental. Physicians often combine these approaches with chemotherapy and radiation.

T Cells. T cells recognize and attack cancer cells. Researchers hope to remove T cells from the body, stimulate growth, and return them in large numbers to fight cancer. Someday, vaccines may be available to promote growth of T cells.

Gene therapy. Many tumors grow because normal genes go awry, changing healthy cells into cancerous cells. Genes that help fight cancer can also fail to work properly. With gene therapy, physicians hope to replace defective genes and encourage the growth of healthy genes.

Laser.High-intensity light shows potential for treatment cancers of skin, trachea, lungs, esophagus, stomach, colon, rectum, and anus.

Hyperthermia. Since the early 1800s, physicians have known that heat can harm some tumors. Researchers now are evaluating hyperthermia to treat cancer of the breast, lymph nodes, skin, eyes, and cervix.

Overview

Cancer is characterized by abnormal growth of cells, which form tumors. It can develop in various tissues and organs of the human body. Cancer cells divide without restraint. They crowd normal cells out and affect their normal function and growth. Cancer cells can spread via the blood or lymph system to other parts of the body. Tumors are masses or growths, which arise from surrounding normal tissue. They may be either malignant or benign. Cells of benign tumors do not invade or destroy surrounding tissues. But the mechanism of cancer developing is not fully known. It is very dangerous disease. An early diagnosis identifies the type and location of the cancer. Cancer can be treated before it spreads to other organs or tissues. Cancer therapy confines and kills the malignant cells. This therapy includes using X-rays, surgical treatment, and chemotherapy.
