What’s more, cancers that arise in the rectum can cause pain in the bottom that is worse after opening the bowels or a sensation of incomplete emptying, and bleeding, he added.
So, what does Mr Kinross advise?
If you’re concerned you should also keep an eye out for other typical symptoms, the colorectal surgeon said.
Other signs to spot include blood in your poo, or a persistent change in your bowel habits, such as going more frequently than usual.
“If you notice these changes lasting for more than two weeks speak to your GP,” Mr Kinross advised.
