Selection and target: Anal cancers usually are local or regional problems (nodes), but sometimes present with evidence of distal spread. I know of no cures if spread, but many with regional (inguinal) nodes. Special targeting and avoidance of healthy bowel can be improved with very fancy treatment plans (imrt). When treatment works (most of the time), its great, when it doesn't outcome is not so good. ...Read moreSee 1 more doctor answer

Yes: In the way you asked the question it can. It depends on the dose. Low dose exposures can allow cells to survive and this could happen. In the treatment with radiation the cancer is treated to levels that are designed to kill the cells and therefore mutation to more aggression is not likely. There are many resistance cancers however and it is more likely the cancer is already aggressive. ...Read moreSee 1 more doctor answer
Low doses of: Diagnostic radiation (like mammograms, chest x-rays) may be exceedingly rare causes. We know that XRT for hodgkin's in young woemn led to excessive risk of breast and lung cancer, and we now use it more sparingly and to lower volume and doses if at all. Even low doses for children to prevent brain relapse in leukemia has been linked to excess brain tumors. But second tumors do not occur in all. ...Read moreSee 1 more doctor answer
Is there a point at which radiation therapy for cancer doesn't help enough to make the side effects worth it?
Yes.: You don't always know if a treatment is going to work on a patient. If the cancer is too advanced and there is little hope of helping the patient the doctor needs to tell a patient and their family so they can consider hospice or comfort measures. Many times radiation actually is a comfort measure and given so their is no side effect but relief of the symptoms. ...Read moreSee 4 more doctor answers

No: We can not take unnecessary radiation as it has it's risk and would give no benefit. However we all get very very low amounts of radiation from the earth and atmosphere. This keeps our bodies repair systems for any damage radiation causes functional. However if we never got any radiation that is what would be best. Radiation therapy is only needed for cancer and other benign conditions. ...Read moreSee 3 more doctor answers
Diagnose vs treat: Radiography means using x-ray beams to create an image that helps diagnose diseases including cancer. Chest x-rays and ct scans are common examples. Radiation therapy uses much higher powered radiation beams that are focused on cancer tumors. These radiation beams are designed to kill the cancer cells. ...Read moreSee 1 more doctor answer
I was wondering what are the procedures of radiation therapy and chemotherapy and how long does the procedure takes to clean the body from the cancer cells?
It depends: Radiation therapy (rt) is used to treat specific spots of cancer, while chemotherapy is used to treat the whole body. Rt is similar to getting an x-ray, but for 15+ minutes repeated every day, for weeks to months. Chemotherapy is an IV medicine given daily, weekly, or every few weeks, over several months. Details depend on the type of cancer being treated. ...Read more
