Answer

Cancer treatment: The common approaches for treatment of cancer are:
  1. Surgery: The tumour cells are removed with the help of surgery to check the spread of cancerous cells.
  2. Radiation therapy: A lethal irradiation of tumour cell is done, taking proper care of the normal tissues surrounding the tumour mass.
  3. Chemotherapy: Cancerous cells are killed by several chemotherapeutic drugs. These drugs exhibit side effects like hair loss, anaemia.
  4. Immunotherapy: In this method, biological modifiers like α-interferons are used which activate the immune system and help in destroying the tumour.
