Treatment of Cancer

Common treatment prescribed for different types of cancers are:

Surgery

Generally a tumor is surgically removed wherever possible.

Radiotherapy/Radiation therapy

Tumor cells are irradiated lethally by gamma radiations taking proper care of the normal tissues surrounding the tumor mass or neoplasm. e.g., use of 1131 for thyroid cancer.

Chemotherapy

Several chemotherapeutic drugs are used to kill cancerous cell. Some of these are specific for particular tumor e.g. two anticancer drugs, vincristine and vinblastine, used in the treatment of leukaemia are obtained from common weed Catharanthus roseus. Majority of drugs have side effects like hair loss, anemia etc.

Immunotherapy

Sometimes tumor cells are seen to avoid detection and destruction by immune system. So the patients are given substances called biological response modifiers such as a-interferon which activate their immune system and help in destroying the tumor.
