Why Radiation Therapy is Often Used After Breast Cancer Surgery
Radiation therapy is a type of cancer treatment that uses high-energy beams of radiation to kill cancer cells. Radiation therapy can be used as the main treatment for breast cancer or as a follow-up treatment after surgery. After surgery, radiation therapy is used to kill any cancer cells that may have been left behind. This helps to reduce the risk of the cancer coming back in the same area.
There are two types of radiation therapy that can be used after breast cancer surgery: external beam radiation and brachytherapy. External beam radiation is the most common type of radiation therapy used for breast cancer. It involves using a machine to direct the radiation beams at the affected area. This can be done on an outpatient basis, and the treatment typically lasts for a few weeks.
On the other hand, brachytherapy involves placing a radioactive source inside the breast tissue near the cancer site. The radioactive source emits radiation, killing any remaining cancer cells. Brachytherapy is typically used for people with early-stage breast cancer where the tumor is small, and the cancer hasn't spread to the lymph nodes.
Radiation therapy is usually well-tolerated, but it does have some side effects. The most common side effect is skin irritation and fatigue. Many people experience redness, itching, and soreness in the treated area during radiation therapy. Fatigue is also common and can last for several weeks after treatment is completed.
Other potential side effects of radiation therapy for breast cancer may include swelling of the breast tissue, changes in breast size, and stiffness in the shoulder. These side effects are usually temporary and go away after treatment is completed.
In some cases, radiation therapy may not be recommended after breast cancer surgery. This may be due to various factors, such as a low risk of the cancer coming back or concerns about the potential side effects. Your doctor will work with you to determine the best treatment plan for your individual needs.
In conclusion, radiation therapy is often used after breast cancer surgery to kill any remaining cancer cells and reduce the risk of the cancer coming back. It is a commonly used treatment that is usually well-tolerated, but it does have some potential side effects. Your doctor will work with you to determine the best treatment plan for your individual needs. If you have any questions or concerns about radiation therapy for breast cancer, be sure to talk to your doctor.
