My mum has had undergone a colonoscopy 2 weeks ago and they found a 3cm tumour, she had a biopsy taken and the results are back with the GP but he has said that he cannot interpret the results and she needs to speak to the hospital.  We have phoned the hospital and they have said that the colectaral nurse specialist should have been in touch.  We are all going out of our mind with worry, does anyone know what we can do.  We have left messages, tried calling but no response.
