My mum beat cancer. She lost parts of her body in the process and chemo changed her physically (her hair and nails never came back the same). It took three years of regular testing to finally be given the "you're officially cancer free" verdict. Three tense years.
All that said she's incredibly lucky not only to have beat it but not to have to live with additional medication due to it. I know somebody who lost a lot more and while is alive now needs a lifetime of medication to "put in" what the partial removed organs no longer produce.
