My advice to anyone else going through this is to give yourself sufficient time to adjust to the changes in your body. Seek support early. Use every service that is made available to you. Most importantly - be kind to yourself!
After a positive screen test in 2009 at age 50, I was instructed to have a colonoscopy. The procedure in 2010 found a polyp which was removed and as a result, my surgeon suggested I have a further colonoscopy in 2013.
This procedure uncovered a small cancer in the left descending colon.
