My mum has had three primary cancers in her life, breast cancer at 48, bladder cancer at 50 and then oesophagus cancer at 66 thankfully all were caught early and she is extremely fit and healthy at 69. She has endured a lot and has faced cancer each time head on, we nearly lost her with the bladder cancer as it was extremely aggressive but they were able to remove her bladder and build her a new one from part of her bowel so she has never had to wear a bag, 20 years on there's been a few hiccups but you would never know she has ever faced cancer let alone 3 different types. My mum has never smoked, always exercised , is not overweight, has eaten organic foods most of her life and still she has copped cancer. There is no rhyme or reason to why cancer comes back in different parts of our bodies but there is always a chance it will, just like if someone had never had cancer before. I guess what I'm trying to say is just live your life be happy and if something is worrying you get it checked, cancer casts a shadow over all us and it is scary but unfortunately we can't change what our bodies do. I was always more scared of a secondary cancer than another primary, well guess what that secondary cancer has happened for me with no symptoms at all. I still feel completely well thankfully and am 2 weeks into oral chemo to help contain the cancer to my lymph nodes and base of my neck (C7 ).My primary cancer was extremely aggressive and so was my treatment and I was in remission for 18 months, I am hopeful that this treatment will do the trick and again I can say that I am in remission or at the very least contained and stable. I intend like I did before my first diagnosis, during that treatment , while I was cancer free and during this new battle to enjoy every moment of my life and not worry about the what ifs. What ifs will pop up and when they do, let's just smash em back down!!!!
