I was quite fortunate until the last couple of treatments when I was ill. I was much worse physically and severely depressed. Also in that time my period stopped. I didn't have any hair loss. Chemotherapy is the use of drugs to kill cancer cells.
Cells grow by dividing.
Chemotherapy works by damaging cancer cells that are dividing. It travels around the body in the blood stream, attacking cells. The cells most affected by chemotherapy are those which divide rapidly. This means that both cancer cells and normal cells are affected. However, normal cells are able to renew themselves quickly.
