Can a piles turn to rectal cancer?

No: Hemorrhoids are engorged blood vessels under the lining of the rectum/anus. These are benign. They do not turn into rectal cancer.

Very rarely: More common is to have a rectal cancer ignored/confused for hemorrhoids by a doctor reluctant to do a good rectal exam. Either way, consider getting checked by a colorectal surgeon/proctologist.

Great question, no: Piles, or hemorrhoids, are a normal part of our anatomy. They do not turn into cancer. But what we see too often is patients assuming that rectal bleeding, pain, etc is due to hemorrhoids and not get seen. In other words, the symptoms of piles can be the same as rectal cancer. Even though it's uncomfortable and embarrassing people with these symptoms should get examined
