Colon Cancer Support Group
Colorectal cancer, also called colon cancer or bowel cancer, includes cancerous growths in the colon, rectum and appendix. Many colorectal cancers are thought to arise from mushroom-like growths that are usually benign, but some may develop into cancer over time. The majority of the time, the diagnosis of localized colon cancer is through colonoscopy.
Anyway, I read your latest post and glad he's got an appointment for a colonoscopy. I will be on my third one in December (every 3 years if diagnosed with cancer). But do hope for a much better outcome for him:)
All the best!
