In medicine, cancer refers to a malignant tumor originating from epithelial tissue, which is the most common malignant tumor. Accordingly, malignant tumors originating from mesenchymal tissue are collectively called sarcomas. So will irregular defecation lead to cancer? How many times a day is defecation a sign of malignant tumor?

Can irregular defecation cause cancer?

The number of times we defecate every day determines our health. Some gastrointestinal signals can always determine your health. So how much do you know about the number of times you defecate every day? How many times a day is defecation healthy? Many people are not very clear about this. Here's how many times defecation is a sign of cancer. There are thousands of ways to die healthily. As long as you get one, the disease will come to you. For example, if you hold your stool for a long time, colon cancer will target you. American experts believe that defecation three times a day is normal, and defecation once is constipation! In this case, it is estimated that more than 90% people are constipated.

Is defecation several times a day a sign of malignant tumor? Can colorectal polyps become cancerous?

Polyps are actually divided into redundant and non-redundant, and redundant polyps refer to adenomas, especially familial adenomatous polyposis. If one person in the family is diagnosed, other members should carry out relevant examinations and treat as soon as possible to prevent cancer. However, it usually takes 5 to 20 years for adenoma to develop into cancer. The probability of canceration is related to the size, quantity, pathological type and location of adenoma, as well as the age and sex of the patient. Non-neoplastic polyp refers to inflammatory polyp and hyperplastic polyp. It will not become cancerous, but it should be removed as soon as possible.

Etiology of colorectal cancer

The incidence of colorectal cancer is related to many factors, such as eating habits, heredity, colon inflammation and so on.

Dietary factors

Such as a high-fat and low-fiber diet; The content of nitrosamines and their derivatives in animal protein and food is high; Intake of alcohol; Fried food; Vitamin a, c, e and trace element selenium are deficient. Dietary factors are considered to be extremely important factors in the pathogenesis of colorectal cancer. In the United States, advocating the change of eating habits since the 1950s has also confirmed the decline in the incidence of colorectal cancer. In contrast, with the improvement of people's living standards in China, people's eating habits in China have also changed greatly, and there are more and more foods with high fat, high protein and high calorie in the menu. This is also the reason for the rising incidence of colorectal cancer in China.

Some benign lesions of large intestine

Such as chronic ulcerative colitis, colorectal adenoma, familial adenomatosis, schistosomiasis and colorectal polyp. People who have suffered from chronic ulcerative colitis for more than 10 years have several times higher risk of colon cancer than the general population. This is because repeated intestinal inflammation is a chronic stimulus to intestinal mucosal cells, which will lead to uncontrolled growth and malignant transformation over time. The same is true for patients with colorectal polyps, whose relative risk of colorectal cancer is 22 times that of patients without polyps, because polyps themselves are benign, but they may also become malignant.

hereditary factor

It is estimated that genetic factors may play an important role in about 20% patients with colorectal cancer. For example, familial adenomatous polyposis and hereditary nonpolyposis colorectal cancer are the most common hereditary colorectal cancers. It was found that the risk of colorectal cancer in children was 2-4 times higher than that in ordinary people, and about 10%- 15% of colorectal cancer occurred in first-degree relatives with a history of colorectal cancer.

Occupational factors and health habits

Lack of physical exercise will increase the risk of colon cancer. However, it is generally not considered that colorectal cancer is an occupational disease.

Symptoms of colorectal cancer: bloody stool

It is the earliest and most common manifestation of colon cancer. Mild cases only show occasional small amount of bleeding, and only a small amount of bleeding can be known after testing. In severe cases, mucus bloody stool, mucus purulent bloody stool or bloody stool may appear, which is often misdiagnosed as dysentery or hemorrhoid bleeding, delaying the diagnosis time. Due to different cancer sites, the amount and characteristics of bleeding are also different, and long-term bleeding can produce secondary anemia.

abdominalgia

Some patients take inaccurate positioning as the first symptom or persistent dull pain with prominent symptoms, and some patients only have abdominal discomfort or bloating. When colorectal cancer is complicated with erosion, obstruction or secondary infection, obvious abdominal colic may occur due to the corresponding increase of intestinal peristalsis and spasm. Some patients showed typical abdominal pain caused by incomplete intestinal obstruction, that is, the pain was paroxysmal colic, which lasted for several minutes, and gas consciously escaped through the pain, followed by exhaust, and then the pain suddenly disappeared. When the elderly have this symptom, colorectal cancer should be considered first.

Changes in defecation habits

Most of them are changes in defecation times or fecal characteristics. For example, defecation used to be 1 time a day, but recently I don't know why defecation occurs 3-4 times a day, or diarrhea and constipation appear alternately, and the shape of stool changes. Originally, the stool was soft and shaped, but recently it suddenly looks like water, and there seems to be blood or pus in it. Remind me that there may be something wrong with my intestines and I need to go to the hospital for examination. It should be pointed out that these symptoms are also common in other diseases, so if you have the above symptoms, you should have a comprehensive physical examination. Some people are accompanied by a sense of urgency, especially when they are young. If there are no other reasons (including travel, changes in living environment and taking oxytetracycline, etc. ), constipation, diarrhea and other intestinal dysfunction often occur, and formal treatment is still ineffective for more than two weeks, which should be paid attention to, which may be an early sign of colorectal cancer.

anaemia

Male patients, especially those who have no other causes of blood loss or intestinal parasitic diseases, should think of the possibility of gastric cancer or colorectal cancer if they find progressive iron deficiency anemia.
