What symptom is got bowel cancer?

summary

There were more males than females in patients with colorectal cancer, aged between 40 and 60 years. Rectal cancer is a lifestyle disease. So diet and lifestyle are the banes of cancer. In recent years, the incidence of colorectal cancer has been increasing significantly in China. The incidence rate of colorectal cancer increased by 2~3 times in Shanghai alone in 20 years. In particular, the proportion of young people suffering from colorectal cancer is increasing. What symptom is got bowel cancer? Let's talk about it.

What symptom is got bowel cancer?

1、 Stool habit change: stool habit change is a typical symptom of rectal cancer. Due to the rectal mass and its secretions, it can produce intestinal irritation symptoms, resulting in frequent defecation, incomplete defecation, irritability and other symptoms, but the discharge is mostly mucus and pus. At this time, the shape of feces has also changed, and the stool is getting thinner and thinner. At first, these "pseudo diarrhea" phenomenon often occurs shortly after getting up in the morning, which is called "morning diarrhea". Later, the number of times gradually increased, even unable to sleep at night, changed the past defecation habits.

2、 Hematochezia: the early symptoms of rectal cancer are mainly painless hematochezia, and the blood is red or bright red, which is very similar to the symptoms of early internal hemorrhoids, so they are easily confused. In the late stage of rectal cancer, bloody stool is mostly dark red, mixed with mucinous bloody stool or pus bloody stool, sometimes accompanied by blood clots and necrotic tissue.

3、 Intestinal stricture and obstruction: intestinal stricture and obstruction belong to the symptoms of rectal cancer. In the late stage of rectal cancer, because the tumor infiltrates around the intestinal wall, the intestinal cavity is narrow, especially at the junction of rectum and sigmoid colon. Most of them are narrow type hard cancer, which is easy to cause obstruction.

matters needing attention

1、 Control fat intake: whether animal fat or vegetable fat, rectal cancer patients should try to reduce. Too much fat, especially animal fat, can stimulate the secretion of bile acid in the small intestine. When the amount of bile acid in the small intestine is too high, it is easy to become a carcinogen and help the growth of cancer cells. High fat diet is closely related to the occurrence of rectal cancer. 2、 Reduce the intake of fat: rectal cancer patients in the diet to reduce the intake of fat in the diet, the relationship between diet and rectal cancer, which is the most studied is fat, including saturated fat and unsaturated fat. The fat in the diet can promote the growth of cancer cells, but also can make normal cells mutate into tumors in the early stage, so we must reduce the intake of fat. 3、 Appropriate supplement of fiber: if the diet is lack of fiber, the feces in the colon will become dry and hard, coupled with the slow speed, the abdominal wall muscle will become weak, which will prolong the emptying time. If the time is too long, the risk of rectal cancer will be relatively increased. Many studies have confirmed that the fiber in food can dilute the carcinogenic substances in oil, and also accelerate the speed of carcinogenic substances excreted through the digestive system.
