The previous two posts talked about surgery and chemotherapy as options in cancer treatment. The last option to be discussed is radiation therapy. Often, radiation therapy is used in conjunction with surgery and chemotherapy to treat cancer.

Radiation therapy is the usage of high-energy waves and particles (radiation) to attack cancer cells. There are many types of radiation. Microwaves use radiation to heat up food. Likewise, x-rays use radiation to image bones. Radiation therapy uses the same radiation as x-rays in higher doses to treat some types of cancer.

With radiation therapy, special equipment sends high doses of radiation to the cancer cells or tumor. The radiation either kills the cancer cells or prevents the cells from growing and making more cancer cells. The radiation also affects healthy normal cells near the tumor but normal cells can repair themselves while cancer cells cannot.

Radiation therapy is different from chemotherapy in that radiation only affects the part of the body being treated while chemotherapy affects the whole body. As a result, radiation is used for localized tumors while chemotherapy is used on patients that have cancer in multiple areas.


Radiation can be administered in two ways: external beam radiation and internal radiation therapy.  External beam radiation uses a machine to send high-energy radiation from outside the body to the tumor and some of the area around the tumor. External beam radiation treatments for most people are 5 days a week for 1 to 10 weeks. The number of treatments required depends on the size and type of cancer, how healthy you are, and what other treatments you are receiving.

External radiation therapy is painless and takes only a few minutes, however, it takes time to set the machines up so appointments generally take 15 to 30 minutes. While receiving treatment, the patient will lie flat on a treatment table under the radiation machine. While the machine is working, the patient will hear a number of clicking and whirring. As stated previously, the treatment should only take a few minutes.

Internal radiation therapy involves using a source of radiation that is located inside the body. The source of radiation may look like a wire or pellet and is called an implant. The implant is inserted very near or inside the tumor and the radiation travels a very short distance. Implants are placed in the body using needle-like tubes. The implants can either be left in or taken out. If the implants are left in, you will not be allowed to do certain things like being near children or pregnant women for a short period of time. Implants will stop giving off radiation after a few weeks and well cause no harm. Other times, the implants are taken out after they have been in place for several hours or days. While the implants are in the body, the patient must remain in a private hospital room. Doctors and nurses will monitor the patient but they will have to limit contact with the patient. After the implants are removed, the treated area may be sore but normally, patients get back to normal quickly.

As with the other treatments, there are a number of side effects associated with radiation therapy. The most common side effects are fatigue, skin changes, and appetite loss.

The previous blog post discussed surgery as a cancer treatment option. However, it is not the only option available to cancer patients. Surgery is often used in combination with chemotherapy and radiation therapy to fight cancer.  Chemotherapy can be used to shrink tumors before surgery or radiation. Also, chemotherapy can be used after surgery or radiation to kill any cancer cells that are left.

Chemotherapy is the use of strong drugs to treat cancer. Chemotherapy was first used as a cancer treatment in the 1950s. There are over 100 chemotherapy drugs used today. A doctor will choose which drugs to use based on the type of cancer and how far it has progressed. In addition to its usage in curing cancer, chemotherapy is also used to slow cancer’s growth, to keep cancer from spreading, to kill cancer cells that may have spread to other parts of the body, and to relieve pain and blockages caused by cancer.


Chemotherapy drugs target rapidly dividing cells in the body. This includes cancer cells as well as normal tissue cells. However, normal tissue cells can generally repair themselves and recover from the damage done to them by chemo drugs.

Chemotherapy is administered in a number of ways.  Generally, chemo is administered directly into the bloodstream using a tiny plastic tube that is put in a vein called a catheter. This method of chemo administration is called intravenous chemo. Chemo can be a pill or liquid that is taken like any other drug under the doctor’s directions.  Chemo can also administered with a needle like a flu shot. Lastly, chemo can be administered directly onto the spine, chest, skin, or abdomen.

Chemotherapy is generally done in cycles, with breaks in between. These breaks allow the body to repair itself and rebuild healthy new cells in between chemotherapy cycles. Chemotherapy can be administered once a day, once a week, or even once a month. How often one receives chemotherapy and how long they receive chemotherapy treatments for depends on the type of cancer, the treatment goals, and how one’s body responds to the drugs used. Other than a little pain from when a needle is used, chemotherapy should not cause any pain.

As chemotherapy drugs are extremely strong, there are a number of side effects associated with chemo. However, some people may have no side effects at all. If the side effects become really bad, a doctor may suggest blood tests to find out if a lower dosage is needed or if longer breaks are needed between doses. The side effects of chemotherapy generally will go away with time after the treatments end but how long it takes varies from person to person.

Common chemotherapy side effects included nausea and vomiting, hair loss, bone marrow changes, mouth and skin changes, changes in your sex life, permanent fertility problems, memory changes, and emotional changes. Bone marrow changes can affect your red blood cell count, resulting in shortness of breath, can affect your white blood cell count, resulting in an increased chance of infection, and can affect your platelet count, making you susceptible to bleeding.
