Chemotherapy for Breast Cancer


Chemotherapy involves using anticancer drugs to help control or prevent the growth of cancerous tumors; Chemotherapy is often used as an adjuvant (supplemental) therapy in addition to other treatments such as surgery or radiation therapy, which are designed to achieve local (breast/chest) control of the cancer.

Normally, chemotherapy is administered through a semi-permanent catheter (a flexible tube) implanted into a large vein, or by smaller, temporary, intravenous catheters placed into the smaller veins in the arm or hand. Some chemotherapy drugs are administered orally in the form of pills or liquid. Chemotherapy may also be given intramuscularly (injected in the muscle), under the skin, or injected locally into the cancer area.

Chemotherapy is used to:

  • Decrease the chances that cancer will come back after breast cancer surgery.
  • Shrink breast cancer before surgery, when the tumor is large or it is inflammatory cancer.
  • Control the disease when the breast cancer is found in the lungs, bones, liver, brain, or other parts of the body.

Chemotherapy is usually given in cycles during which you have treatment for a period of time, and then you have a few weeks to recover before your next treatment. Depending on the drugs you take, you may have your chemotherapy at home, in your doctor’s office, in a clinic, in a hospital. How often and how long you have chemotherapy will the drugs that are used and how your body responds to them and the goals of the treatment. You should follow the schedule prescribed by your doctor.

Throughout chemotherapy, your oncologist and nurse will watch how respond to the therapy. You will have frequent physical exams and blood tests. You should check with your doctor before taking any other medications during your treatment.

Chemotherapy affects all fast- growing cells throughout the body. Therefore, in addition to killing cancer cells, it also kills fast- growing normal cells. This is what may cause side effects such as hair loss, mouth sores, and fatigue. Today, because of what has been learned in research studies, doctors are able to control, lessen, or avoid many side effects of chemotherapy.

Possible Problems (side effects)

Chemotherapy can cause short-term and long–term side effects that are different for each patients, depending on the drugs used.

The most common short –term side effects that may appear during chemotherapy include; loss of appetite, nausea, vomiting, diarrhoea, constipation, fatigue, infections, bleeding, weigh change, mouth sores, and throat soreness. Some of these problems may continue for some time after chemotherapy ends.

Some drugs cause short –term hair loss. Hair will grow back either during treatment or after treatment is completed. Before you start chemotherapy, you may want to have your hair cut short, or buy wig, hat, or scarves that you can wear while going through treatment.

Serious long –term side effects may include weakening of your heart, damage to your ovaries, infertility, early menopause, or second cancers such as leukemia (cancer of the blood). These side effects may not appear until later, sometime after chemotherapy is completed.

Fighting infections

You are more likely to get infections during this time. You can help yourself stay healthy by following these steps:

  • Finish dental work before starting chemotherapy. You cannot have dental work during chemotherapy.
  • Eat a healthy diet and plenty of rest.
  • Stay away from large crowds and from anyone with a cold, infection, or contagious disease.
  • Bath daily, wash your hands often, and follow good mouth care.
  • Wear Gloves to protect your hands against cuts and burns.
  • If you cut yourself, keep the wound clean and covered. Talk with your doctor or nurse about applying antibiotics or medications.


During chemotherapy, you may stop having monthly periods. You still can get pregnant, so talk with your doctor about birth control. The effect of chemotherapy on an unborn baby is unknown. After your treatment is over, your ability to get pregnant will depend on your age and the types of drugs you received. If you plan to become pregnant after, talk with your doctor before starting chemotherapy.

Managing nausea

Feeling nauseous, or as if you have to vomit, is a common side effects of chemotherapy. Your doctor can prescribe medication to help with this problem. Good nutrition is especially important during cancer treatment. The following suggestions may help:

  • Eat small meals often; do not eat 3 to 4 hours before your treatment.
  • Eat whatever you can tolerate; for example coconut water, Lemon water with sugar and salt, butter water (lussi), washed plums, ice creams, ginger in any form, oatmeal, baked potatoes, and fruit juices mixed with water etc.
  • Eat only overcooked and fresh meals.
  • Chew your food thoroughly and try to relax during meals.
