what does a hemorrhoids look like,Blood in the stool must be checked for rectal cancer!

    In daily life, hemorrhoids and rectal cancer may have the same or similar symptoms (such as blood in the stool), which makes some patients relax their vigilance. In fact, the condition of blood in the stool and hemorrhoids in colorectal cancer is slightly different.

    Hemorrhoids can occur in people of any age, and patients with rectal cancer are mostly middle-aged or elderly. Hemorrhoid patients have blood in the stool, which is caused by scratching the affected area during defecation. Most of the blood drips with the stool, so it does not mix with the stool, and there is no mucus. The stool of patients with rectal cancer is often mixed with blood, mucus and pus, and the stool habits will change significantly.

    [Long-term constipation, one of the causes of colorectal cancer]

    Long-term constipation can lead to higher and higher concentrations of carcinogens remaining in the stool. Long-term contact of the intestinal wall with these carcinogens may be a predisposing factor for colorectal cancer. At the same time, constipation is also one of the manifestations of colorectal cancer. Because the descending colon on the left is stenosis, if the tumor is on this side, it will often be obstructed and cause constipation. The doctor can basically determine where the colorectal cancer is through consultation and digital examination.

    [Changes in bowel habits are also a sign of rectal cancer]

    Changes in bowel habits should not be taken lightly, which may be a precursor to rectal cancer. Changes in bowel movements include many aspects. For example, normal bowel movements are relatively dry, but they have suddenly become thinner or become dry in the past few days; in some people, the frequency of bowel movements has changed from once a day to two or three times, or vice versa. In short, if there is abdominal discomfort, pain, local lumps, tenesmus, stool characteristics and shape changes (from dry to thin, with mucus and blood, or stools are not shaped, thin and flat), that is, the bowel movement is not the same as the usual regularity. , You should go to the hospital for a specialist examination as soon as possible.

    [Prevention of rectal cancer requires a scientific attitude]

    In addition to regular colonoscopy screening, it is also important to emphasize that the diet must be healthy. It is forbidden to eat spiced foods, eat less pickled food, eat less glutinous rice food, eat less instant noodles and other industrial fried and puffed foods; develop a good life Habits, do not smoke, do not drink alcohol; pay close attention to changes in stool characteristics and bowel habits: when mucus, bloody stools, black stools, irregular stools, thinner stool notes, changes in stool and bowel habits, changes in bowel frequency, frequent diarrhea or When you have difficulty defecation and other symptoms, you must go to the hospital to see a doctor for examination.
