Hemorrhoids can produce several uncomfortable, but non-serious problems. A blood clot in the hemorrhoid may cause severe pain and usually demands immediate medical attention. Hemorrhoids can ooze fresh red blood, whether located externally or internally. External hemorrhoids often cause dripping of blood from the anus while sitting on the toilet. The blood might also be seen as soiling of the underwear. Internal hemorrhoids that bleed may produce fresh blood in the stool. External hemorrhoids can be itchy, especially if the area is moist and irritated.
Hemorrhoids do not develop into cancer. However, both hemorrhoids and cancer can cause rectal bleeding. In fact, many disorders can be the cause of rectal bleeding. When rectal bleeding occurs in persons over age 30, and especially in those over age 50, it should be considered a serious problem until an exact diagnosis is made. The physician who directly examines the rectal area can make the specific diagnosis.
