Chemotherapy is a type of cancer treatment that uses drugs to destroy cancer cells. Chemotherapy works by stopping or slowing the growth of cancer cells, which grow and divide quickly. But it can also harm quickly dividing healthy cells, such as those that line the mouth and intestines or cause hair to grow. Damage to healthy cells may cause side effects.
Often, side effects get better or go away after chemotherapy is over. This can be given before surgery or radiotherapy, called Neoadjuvant Therapy, or after, called Adjuvant Chemotherapy. Chemotherapy may be used to destroy cancer cells that have come back (recurrent cancer) or spread to other parts of the body (metastatic cancer). Earlier, there used to be less number of chemotherapy drugs but today, we have several options of giving 1st, 2nd, and 3rd line drugs. Low dose metronomic chemotherapy is also showing some promising results.
