Recently, people always ask me, “Doctor: I have blood in my stool, is it hemorrhoids? It’s not rectal cancer, right?

So let us tell you the difference between rectal cancer and hemorrhoids. 1.Blood in stool is one of the main symptoms of hemorrhoids. The characteristic of hemorrhoid bleeding is that bleeding occurs during defecation and does not bleed after defecation. It is often intermittent blood in the stool, bright red in color, and can be dripping, spraying or with blood on the stool paper. Bleeding hemorrhoids are often painless, and repeated bleeding over time can cause anemia. The reason for the bleeding is that the elevated varicose veins of the hemorrhoid are rubbed during defecation and the pressure in the blood vessels is increased by the force of defecation, so it is easier to occur and aggravate the blood in the stool when the stool is dry and hard. 2, swelling and pain internal hemorrhoids are generally not painful, but when there are embedded infection, thrombosis and other complications often occur swelling and pain, the pain increases when defecating, accompanied by redness and swelling and hot pain and swelling. 3.Extra-anal masses are often dominated by external hemorrhoids, often with unclean wipe after stool, discharge and occurrence of dampness and itching outside the anus, and sometimes swelling and pain. This is a symptom of the larger internal hemorrhoids and mixed hemorrhoids turning out from the anus, and in serious cases the appearance is like a wreath, which can be self-retracted after a bowel movement in the early stage, or can be retracted after bed rest or hand support in the middle stage, or can be retracted with difficulty or incomplete retraction in the late stage, making it semi-prolapsed and turned out for a long time, accompanied by extra-anal discharge, skin ulcers, as well as local itching and discomfort, and inflammation of the hemorrhoid nucleus. Rectal cancer is more frightening, and some need to dig out the anus! At present, the incidence of rectal cancer is increasing year by year and is getting younger.

Change in bowel habits is the earliest and most common symptom of rectal cancer.
