Totally normal, i feel i shouldnt complain but we are human and individual, cancer effects people in different ways, i have immature terratoma what was mis-diagnosed as irritable bowel for three years before the tumour turned and was 18 inches wide i was never aware as symptoms were very mild. People kept telling me i was lucky.........Never think someone is better off as its circumstancial you are an individual and far from lucky its not lucky you got cancer just unfortunate, Keep strong sending big hugs
