My girlfriend has stage IV squamous cell carcinoma and has been offered pembrolizumab which if successful may give her some extra months. However she has also been told the side effects can be very nasty, and some people have died from the treatment. She already has bowel diseases and a weak heart so she is scared she would react badly to treatment. She feels she would rather have less months of feeling better, than go through nasty side effects and end up in hospital again. I was interested in hearing from others who have faced this dilemma, and also if anyone has had alternative treatments for this particular type of cancer and stage 4. She has been told chemotherapy would be no good, and nor would radiotherapy. The consultant said she may have 4 to 5 months left without treatment, and 7 to 12 months with immunotheraphy. Kind regards.
