Thank you Brian for this forum,and for all you do for all of us. I haven't posted for years, but looking for some answers I have ended up back here. I am 7 years since my treatment. I am having problems with BP, and have an MRA scheduled for this Monday for stenosis in carotid artery. My bloodwork has been good, so I was curious why this was happening. I even asked the doctor if it could be related to radiation I had received. He just said that was a good question. Reading your post and doing some research has helped me to see that it could be a result of treatment. I'll know more next week, hopefully. But wanted to thank you for sharing.
