How Effective Is Radiation Therapy For Breast Cancer
Very effective.: Radiation therapy (rt) is never a primary treatment for breast cancer, but rather a supplement to surgery for the local treatment of breast cancer. Rt is mandatory following breast conserving surgery: local recurrence rates are decreased from >25% to <5% with rt. Rt is also used after mastectomy for patients that are at high risk for local recurrence. ...Read moreSee 2 more doctor answers
Breast cancer results when glandular cells lining the milk ducts and lobules of the human breast begin to grow in an unregulated manner. The growth occurs initially inside the ducts but eventually breaks outside into the breast tissue and ultimately spreads both to the lymph nodes in the armpit and via the bloodstream to other parts of the body. Because of the promoting affect of estrogen almost all breast cancer occurs in women and is a rarity in men. The unregulated growth is due to both inherited and acquired genetic defects. It is the most common malignancy in women but it often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast ...Read more
Fairly effective: Radiation plays an important role in treating breast cancer. In the neoadjuvant setting it can reduce the size of a relatively large lesion making surgery more effective. It can be used to treat micro disease in axilla and after lumpectomy can be used to enhance survival and reduce local recurrence. In metastatic bone disease it can control in not eliminate disease. ...Read more
Early results good: Published results of intraoperative radiation therapy, iort, (targit-a trial) have found no difference as compared to traditional whole-breast radiation therapy in a subset of people at low risk for recurrence. While promising, we await long-term data before expanding this option to more people. To-date, my experience has been very favorable. ...Read moreSee 2 more doctor answers

Please be careful of claims made by alternative treatments for cancer and ask for independent well controlled studies that demonstrate benefit. At this time alternative treatments are of a supportive role to more conventional therapies. I personally know of women whose cancer got worse while they tried alternative methods. ...Read moreSee 2 more doctor answers

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more
