After feeling very tired for a long period, having regular blood tests and visiting my local doctor, I was told to have a colonoscopy. Due to my very low iron levels my doctor felt I could be bleeding internally so I was pleased when I was able to book the colonoscopy for a couple of days later. After the colonoscopy was over I was told that I had bowel cancer. Shock, horror at that word. No one in my family had ever had cancer.
