I do have a long-standing inguinal hernia for almost greater than 20 years, left untreated as it was not causing any difficulties since then but in the recent four to five months it feels a bit discomfort and it is creating a gurgling sound as it was with its onset. In the month of August 2017, I had mucus in stools and had 1 episode of blood in stool as well as diarrhea but then it subsided after taking meds,as I am having IBS. Can hernia lead to cancer of colon or stomach or testicular cancer?
