First off, all the best to your uncle. My nan on my mum's side had breast cancer but none of my family ever speak about it for obvious reasons so im guessing it was before i was born. She is now well. More recently, my dads best friend was diagnosed with a form of cancer(cant remember which) and was given very little time to live. He recovered and all seemed well and it happened again. After being in hospital for weeks they found out he was misdiagnosed and hes now alot better.
