She has carcinoma of the sigmoid colon, and the stage of cancer is III. For this, she will need atleast six chemotherapy cycles which are given every three weeks.

Thanks for your reply.
I have one more question, how the doctor knows that chemotherapy is working after a few sections? Is there any measurement or test that doctor uses before and after chemotherapy to decide whether the patient needs chemotherapy or not?
As the surgery is done already, there is no cancer in her body right now. Chemotherapy is given to cut out the microscopic cancer cells in the blood that are not visible on any scans and not removed during surgery as they are too small to remove.
Scientific data has proved that chemotherapy after surgery helps in preventing the disease from coming back.
