Hi, I have anal cancer that has spread to my lungs and was diagnosed stage 4 two and a half years ago, I've had chemotherapy up until it stopped working 12 months ago. I may now have the option of sabr radiotherapy to the tumours in my lungs, depending on the results of my PET scan today. Has anyone else had sabr to the lung for metastasis not primary lung cancer and if so what were the side effects and more importantly the results
thank you
