Question

List various means of cure of cancer.

Answer 1

(i) Surgery: Removal of the cancerous cells; useful in breast or uterine tumours but has limited usefulness. 

(ii) Radiotherapy: Bombarding cancer cells with rays that damage them while causing minimum damage to normal tissue. 

(iii) Chemotherapy: Anti-cancer drugs that interfere with cell division and growth; may cause hair loss and anaemia, which correct after treatment stops. 

(iv) Immunotherapy: Antibiotics and transfusions are given to prevent infection and anaemia, and biological response modifiers such as interferon are used to strengthen the natural anti-cancer immunological defence.
