What happens during chemotherapy and what are the side effects?

My sister went through breast cancer chemo last year. Three practical things: 1) Stock up on ginger tea and plain crackers for nausea. 2) Get a good water bottle — staying hydrated reduces side effects significantly. 3) Ask the oncology nurse about the cold cap to help prevent hair loss. Also, Macmillan Cancer Support (0808 808 00 00) were absolutely brilliant — free practical and emotional support.

Chemotherapy uses anti-cancer drugs to destroy cancer cells. It is given in cycles — usually a treatment session followed by a rest period. Common side effects include tiredness, feeling sick, hair loss, increased risk of infections, bruising and bleeding, sore mouth, and changes in appetite. Not everyone gets all side effects, and there are medicines to help manage many of them.
