The objective of radiation therapy to the breast is to kill cancer cells that could otherwise persist after therapy and cause breast cancer to relapse locally in the breast, surrounding chest wall, or axilla. Radiation therapy uses high energy x-rays to kill cancer cells that remain in the...
Although radiation therapy (RT) has been shown to reduce 15-year mortality in breast cancer, it is associated with an increased risk of some types of secondary malignancy. To evaluate this risk, Kirova et al. conducted a retrospective review of the records of 16,705 patients treated for non...
Radiation Treatment for Breast Cancer: Radiation therapy is often used for patients who have had surgery to remove the breast cancer. There are two types of radiation treatment for breast cancer, internal and external radiation treatment. Answer and Explanation:1 ...
Types of Radiation Therapy Radiation can come from a machine outside the body (external-beam radiation therapy) or from radioactive material placed in the body near cancer cells (internal radiation therapy, more commonly called brachytherapy). Systemic radiation therapy uses a radioactive substance, ...
One of the most common treatment modalities for breast cancer is radiation therapy, but patients may have problems coping with its undesirable effects.
CTCs are found in an estimated 15 to 25 percent of patients with early-stage breast cancer. "Our findings provide initial robust evidence that testing for circulating tumor cells may be an important tool in helping to guide recommendations for radiation therapy," said Chelain Goodman, a resident...

Radiation therapy is used to treat many types of cancer, including cancer of the lung, breast, prostate, testicles, and brain.When a tumor is going to be removed surgically, radiation can shrink it. This reduces the amount of normal tissue that needs to be removed near the tumor. When ...
Objective To study the role the left ventricle (LV) as a novel organ at risk (OAR) in postoperative intensity modulated radiotherapy (IMRT) for left-sided breast cancer patients who received breast conserved surgery (BCS) to protect the heart from unnecessary radiation.MethodsThe archived computed...
A group of investigators in the United States has determined that radiation therapy may not be the best approach to treat breast cancer. Though the radiations kill off more than half of tumor cells every treatment, they also trigger changes in surviving cancer cells. These changes make them mor...
