Hello, 4 years ago I was diagnosed with TN breast cancer, Grade 3 stage 1. Luckily treatment worked..chemo, lumpectomy and radiotherapy. During all that I found out I was brca2 positive so then went on to have risk reducing surgery, ovaries and fallopian tubes removed and then double mastectomy. My question is regarding the risks of reoccurring or new cancers due to xrays and scans. Over the last year I have had an xray on my foot for suspected broken toe, 3 head ct scans 1 without and 2 with contrast because of the awful headaches I'd been getting (luckily all came back clear) now my GP wants me to have a chest xray as I have been suffering with a chest infection for the last 3 and half weeks. I have refused the xray once and have postponed it until finishing my third course of antibiotics, hoping that it will clear up and there will be no need for the xray. I'm just so worried that all these scans and xrays iv been having is going to significantly increase my risk of reoccurrence or getting a new cancer in the future. Can you please tell me about the risks when exposed to this much radiation, I understand the benefits of having them but it's the risks I'm more concerned about. I'm trying so hard to make lifestyle changes, dietary changes and anything else that may reduce my risk of getting cancer again in the future I just don't want all my hard work undone by unnecessary exposure to radiation. So scared of getting cancer again!
