Radiation Therapy Program: What to Expect With a Program of Radiation Therapy
Custom Search
A radiation therapy program is a treatment for cancer that's designed to control malignant cells – it can be both palliative (used simply for symptom relief when a cure is not possible) or therapeutic (as a curative treatment).
That means radiation therapy does not always mean the patient will be cured, but it can be a possibility depending on the type of cancer and how far progressed it is.
Side Effects of Radiation Therapy
Generally, radiation therapy itself is actually quite painless and most low-dose palliative treatments have little to no side effects.
However, if a patient is exposed to higher doses during their radiation therapy program, the side effects can be both unpleasant and intense. The severity and nature of these side effects depends on the type of radiation used, the patient and which organs actually receive the radiation.
Side effects are generally limited to the area of the body that is being treated, but can vary depending on the above variables.
Damage to the Skin or Internal Lining
Damage to the skin, lining of the throat or stomach, bowel mucus or esophagus are all possible. The skin or lining can become pink or sore and may break down.
If the area treated includes the mouth and throat, swallowing can become painful and the patient may need painkillers. If the area treated includes the bowels, symptoms often include diarrhea, nausea and soreness.
Swelling
During radiation therapy, swelling of the soft tissues is often common, and can be a major concern when treating brain tumors or brain metastases. Some patients may receive steroid treatments in an effort to reduce internal swelling.
Infertility
If the area to be treated includes the reproductive organs, infertility is a possibility. The ovaries and testicles are both very sensitive to radiation and after direct exposure, may become infertile.
Hair Loss
Hair loss is most obvious in patients who receive radiation therapy to their brains. Unlike chemotherapy, this type of radiation-induced loss of hair is permanent, but typically limited to the area that is treated.
Dryness
Dry mouth and dry eyes are a common symptom of those obtaining radiation therapy – these can become long-term and directly affect the patient's quality of life. Also, sweat glands in and around the area treated often stop functioning.
Fatigue
General fatigue is a common symptom experienced by most radiation treatment patients. Patients typically feel tired, fatigued and unable to handle high levels of stress or physical activity.
Cancer
Though very rare, a radiation therapy program can result in secondary malignancies – essentially causing cancer again and typically many years after their original treatment. Again, this is rare and the benefits of treatment often outweigh the risk.
