Radiation Therapy for Breast Cancer
Breast cancer is a common form of cancer among women, with approximately one in eight women being diagnosed with this disease. There are several treatment options for breast cancer, and radiation therapy is one of the most effective and commonly used treatments.
What is Radiation Therapy?
Radiation therapy is a cancer treatment that uses high-energy radiation to kill cancer cells. It works by damaging the DNA of cancer cells, which prevents them from dividing and growing. Radiation therapy can be given externally or internally, depending on the type and stage of cancer.
External radiation therapy involves using a machine to deliver radiation beams to the affected area from outside the body. Internal radiation therapy, also known as brachytherapy, involves placing radioactive materials inside the body near the cancer cells.
Why is Radiation Therapy used for Breast Cancer?
Radiation therapy is often used in combination with other treatments for breast cancer, such as surgery and chemotherapy. It is used to destroy any remaining cancer cells after surgery or to shrink tumors before surgery. Radiation therapy can also reduce the risk of the cancer coming back in the same breast or nearby lymph nodes.
Types of Radiation Therapy for Breast Cancer
There are two main types of radiation therapy for breast cancer:
- External beam radiation therapy: This involves using a machine to deliver radiation beams to the affected breast or chest area from outside the body. The treatment usually lasts for several weeks, with sessions taking only a few minutes each day.
- Internal radiation therapy: This involves placing radioactive materials inside the breast near the cancer cells. The treatment usually lasts for a few days, with the materials being removed after the treatment is completed.
Side Effects of Radiation Therapy for Breast Cancer
Like all cancer treatments, radiation therapy has side effects. The side effects depend on the type and dose of radiation therapy given, as well as the patient's individual response to the treatment.
The most common side effects of radiation therapy for breast cancer include:
- Skin changes: The skin in the treated area may become red, dry, and itchy. In some cases, it may even peel or blister.
- Fatigue: Many patients experience fatigue during radiation therapy.
- Breast swelling: The breast may become swollen and tender during radiation therapy.
- Lymphedema: Radiation therapy can increase the risk of lymphedema, which is a swelling of the arm or hand on the same side as the treated breast.
- Changes in breast size and shape: Radiation therapy can cause the breast to shrink or become firmer.
Managing Side Effects of Radiation Therapy for Breast Cancer
There are several ways to manage the side effects of radiation therapy for breast cancer. These include:
- Moisturizing the skin: Patients are advised to use a gentle moisturizer to keep the skin in the treated area hydrated.
- Resting: Patients are advised to rest as much as possible during radiation therapy to combat fatigue.
- Compression garments: Patients with lymphedema may benefit from wearing a compression garment on the affected arm or hand.
- Physical therapy: Physical therapy can help to relieve lymphedema and manage changes in breast size and shape.
Conclusion
Radiation therapy is a highly effective treatment for breast cancer. It can help to destroy cancer cells and prevent the cancer from coming back. However, like all cancer treatments, radiation therapy has side effects that need to be managed. Patients should discuss the benefits and risks of radiation therapy with their doctors to make an informed decision about their treatment options.
