Progress in cancer treatment

Progress made in cancer research and treatment is a result of success in biochemistry, molecular biology, genetics, immunology and virology. Experimental studies have proved that viruses of animal species may produce malignant tumours in other animals. When test monkeys at the Institute of Experimental Pathology were given suspensions from patients suffering from cancer of hematogenic system, they developed different forms of acute and chronic leukemia. A possible agent of this disease has been isolated and its role in the de-elopment of human cancer is being studied. Our immunologists have found unique early diagnosis llii'lhods for cancer of the liver. The present research aims at accurate early detection for every type of malignant tumours.

Progress has been made in developing drugs that prolong [the cancer patients' lives. Several new preparations can be mentioned — ftorafur used for cancer of the breast and the large intestine, rubomycin used in acute leukemias, bruneo-mycin, ftorbenzotein and others. Currently there is a lot Of research on drug combinations and applications. Some malignant tumours that do not yield to any single preparation have reacted to combinations of drugs.

The cancer control programme includes both social and medical measures. There are many specialized treatment, prevention and research centres where surgery, radiation and chemotherapy are used. The combination of chemotherapy, surgery and radiation (including elementary particle beams and laser pulses) more and more often brings positive results. Further research and development of preventive and curative methods will lead to new achievements.

3) Перекладіть з російської мови на англійську

Доброкачественные опухоли растут медленно, могут существовать годами, не увеличиваясь. Они окружены собственной оболочкой. При росте, увеличиваясь, опухоль отодвигает окружающие ткани, не разрушая их. Гистологическое строение опухоли незначительно отличается от ткани, в которой она развивалась. Поэтому доброкачественные опухоли носят названия собственных тканей, из которых они развились, с добавлением суффикса "ома" от греческого термина "онкома" (опухоль). Например, опухоль из жировой ткали - липома, из соединительной - фиброма, из мышечной - миома, из костной ткани - остеома и т. д. Удаление доброкачественной опухоли с ее оболочкой ведет к полному излечению больного.
