Radiation therapy Radiation therapy External beam radiation uses high-powered beams of energy to kill cancer cells. Beams of radiation are precisely aimed at the cancer using a machine that moves around your body. Radiation therapy for breast cancer uses high-energy X-rays, protons or other particles to kill cancer cells. Rapidly growing cells, such as cancer cells, are more susceptible to the effects of radiation therapy than are normal cells. The X-rays or particles are painless and invisible.
Types of Radiation Therapy for Breast Cancer Treatment | OncoLink
February 14, For many patients with breast cancer, radiation therapy is an important aspect of treatment. Most commonly, radiation is used after surgical removal of breast cancer to kill any remaining cancer cells. Radiation therapy damages DNA and kills cells in a particular area the "field" of radiation. Radiation oncologists can target radiation to different areas using different techniques. The possible techniques will depend upon the type of surgery and location and extent of the cancer. Here, we will review some of the common forms of radiation therapy for patients with breast cancer.
Breast cancer risk following radiotherapy for Hodgkin lymphoma: modification by other risk factors
Discussion No previous study to date has examined the influence of breast cancer risk factors and radiation dose in relation to breast cancer risk among young women treated for HL. Extensive efforts were made to estimate radiation dose to the area where the breast tumor occurred, and that received by the ovaries, and to collect details regarding cytotoxic drug treatment. In additive RR models, the combined effects were in the direction of less than additive. Our findings also are supported by the persistence of altered breast cancer risk among women from sites that collected information from cancer registries or questionnaires, and among women with a first-degree family history only. Some evidence supports the possibility that women with a family history of breast or ovarian cancer may have an altered response to radiation.
Some women with breast cancer will need radiation, often in addition to other treatments. The need for radiation depends on what type of surgery you had, whether your cancer has spread to the lymph nodes or somewhere else in your body, and in some cases, your age. Tumors that are large or involve the skin might also need radiation. You could have just one type of radiation, or a combination of different types. Radiation therapy is treatment with high-energy rays such as x-rays or particles that destroy cancer cells.
