Treatment of Cancer:
Cancer treatment consists of combination
of a number of therapies which are follows:
i. Chemotherapy:
Chemotherapy comprises administration of certain anticancer drugs. The anticancer drugs check cell division by inhibiting DNA synthesis or are more toxic to cancerous cell than to normal
cells. Chemotherapy may lead to hair loss
or anaemia but both get corrected after the
treatment is stopped.
ii. Radiotherapy:
It is used in addition to chemotherapy. In radiotherapy, the basic principle is to bombard the cancerous tissue or cells with the rays from radioactive materials. For treatment, the cancer tissue or cells are exposed to radiations from
radioactive materials such as cobalt, iridium and iodine. The rays x-rays gamma rays and charge particles are used to destroy the cancerous tissue or cells but cause minimum damage to the surrounding normal tissue or cells.
iii. Surgery:
In surgery, the entire cancerous tissue or cells are removed surgically. It has limited utility. In certain cases such as breast tumor or uterine tumor, the surgery is most effective, but other treatments are also given to kill any cancerous cell that may have been escaped in surgery.
iv. Immunotherapy:
Tumor cell have been shown to avoid detection and destruction by immune system. Therefore, the patients are given substances called biological response modifiers such as α-interferon which activates their immune system
