Definition

Chemotherapy is medicine used to destroy cancer cells. It is toxic to fast-growing cancer cells. It can also affect fast-growing healthy cells, like blood cells, lining in stomach, and hair.

Reasons for Procedure

Chemotherapy is used as a part of cancer treatment. The role it will play will be based on the type of cancer and how advanced it is. Chemotherapy may:

• Cure cancer—Cancer cells are destroyed to the point that cancer can no longer be found in the body. The cancer cells will not grow back.
• Control cancer—Chemotherapy may keep cancer from spreading or slows its growth. It may also destroy cancer cells that have spread to other parts of your body.
• Ease cancer symptoms—It may be given to shrink tumors that are causing pain or pressure.

Side Effects

The medicine attacks fast-growing cells. It can also hurt healthy cells and lead to side effects. Side effects vary. The type of medicine and type of healthy cells affected will determine what symptoms you have.

Damage to healthy cells that line the mouth, stomach, and intestines can cause:

• Nausea or vomiting
• Diarrhea or constipation
• Loss of hunger
• Mouth sores

Damage to blood cells can lead to:

• Anemia—low red blood cell count
• Weakened immune system with a higher risk of infections
• Tiredness
• Easy bruising and bleeding

Hair loss may be caused by damage to cells at the root of hairs.

Other areas that may be harmed:

• Nerves—damage or irritation may cause numbness and tingling in the hands and feet called peripheral neuropathy
• Kidney—medicines can pass into urine and damage kidneys
• Heart—certain medicines can harm the heart muscle
• Reproductive organ—some chemotherapy medicines may cause:
  • Infertility
  • Menstrual cycle problems

The medical team will choose a plan that works best and has the fewest problems. Other methods may also help manage problems.
