I've had MS for 32 yrs. Never had a problem with bowel or bladder.
Radiation oncologist says that ms is a contradiction to radiation treatment.
They have no data to support this. I need treatment for the cancer as I'm only 56 yrs old. There is no evidence that radiation makes MS worse. However, radiation should avoid the parts of the nervous system affected by MS, such as the brain and spinal cord. The radiation oncologist take special precautions to avoid these areas.
