NHS England is to lower the age at which people are first invited for bowel cancer screening from 60 to 50. Early diagnosis will save lives and I want  NHS Wales to do the same. I am a Welsh resident who was diagnosed with bowel cancer at the age of 58, during an emergency admission to hospital.  I have been fortunate that surgery and chemotherapy has been effective for me, but it is not the same for everyone.  Please support my petition for screening at 50 in Wales.
