They reckon scientists are getting near to finding a cure. My mother died of cancer, but some people luckily are surviving. DO NOT mess about if you have any symptons, blood in your stools or urine get straight to a doctor is my message it may not be serious hopefully. By the way if sometimes you drink any red coloured drink or eat tomatoes you don't realise and after you have been to the toilet you may panick but then you know what caused that, it happened to me a few times.
