Describe the different methods of treatment of cancer.

Answer

Treatment of Cancer:
The following methods (one or in combination) can help to treat cancer.
Surgery:
  • The tumour cells are surgically removed to reduce the load of cancerous cell.
Radiotherapy:
  • The tumour cells are irradiated wholly (but taking care of the surrounding normal cells) with safe doses of radiations.
Chemotherapy:
  • Certain drugs are used to kill the cancerous cells, but majority of the drugs have side effects like hair fall, anaemia, etc.
Immunotherapy:
  • This involves the use of biological response modifiers, like alpha-interferon, which activate the immune system and help in destroying the tumour.
