Hi. In Finland IBS is tabu. Nobody can talk about it, even doctors know too bit about IBS so this is my only chance.First thing, sorry, my English is not very good. I am 21-years-old Finnish guy and I have had IBS many years but I got a diagnosis until recently. I have been on blood tests, all results are good. I also wanted to Fecal occult blood test and I did it in three days (three samples). I heard result about couple weeks ago and all of them were negative (no fecal blood in stool).Yesterday I saw bright red blood in my stool. Stool was brown and "normally", but there were a couple of drops of blood in the head of stool. I know, probably anal fissures, but can I be sure? My age is only 21 and my family has not colorectal cancer. If my colon leakage of blood, after all, it appeared in fecal occult blood test, right? I guess my stool was hard but I´m not sure anymore... I´m so worried even though common sense says that does not concern. The human subconscious is a stupid thing, it doesn´t leave me alone. Last night I have also diarrhea, but I think that it does not relate to blood because I ate very bad yesterday so it could be diarrhea that´s why. I don´t want go to Doc because he only said that anal fissure ant that´s it. I don´t feeling that there should be fissure, of course the could be.In Finland we have statistic according to a 1655 people each year are a visible blood in stools and 11% of them have colorectal cancer.And my situation: How many percent chance of cancer?
