What are the early symptoms of colon cancer?(1) Change in bowel habitsFrequent defecation, diarrhea, constipation, alternating constipation and diarrhea, incomplete defecation, anus swelling, and changes in the shape of the stool (thinning of the stool, and marks in the discharged stool).

(2) Mucoid stool or mucopurulent bloody stool:

Due to the friction of feces, if the surface of the tumor in the intestinal cavity is penetrated and bleeding occurs, it is easy to produce light or light red bloody stools. Because early-stage tumors are relatively small, the incidence of bloody stools is relatively low or only occurs intermittently.

(3) Abdominal bloating and indigestion:

When tumors in the colon develop to a certain extent, they can cause intestinal obstruction, abdominal distension, abdominal discomfort, and intermittent abdominal pain.

(4) Systemic symptoms such as anemia, low-grade fever, fatigue, edema, and unexplained weight loss:

These systemic symptoms are common to many cancers and even non-cancer diseases. They are not specific and are most easily ignored.

What are the causes of colon cancer?Like other cancers, the cause behind colon cancer is not clear, but some related risk factors have been initially clarified, including the following four points:

(1) Dietary habits: Colon cancer is a "rich cancer". A diet high in animal protein, high in fat, and low in dietary fiber is an important reason for the high incidence of colon cancer.

(2) Heredity: Although colon cancer is not a hereditary disease, it has a clear genetic tendency. People with a family history of colon cancer will have a significantly increased risk of colon cancer.

(3) Induced by some diseases: If certain precancerous intestinal lesions are not treated in time, they will also increase the risk of colon cancer, such as chronic ulcerative colitis, polyposis, adenoma, etc.

In addition, poor lifestyle factors such as prolonged sitting, lack of physical activity, obesity, and other factors will increase the risk of colon cancer.

How to detect colon cancer in its early stages?It is still not possible to judge early-stage colon cancer based on symptoms. The symptoms are mild and not specific. When some symptoms are obvious, the disease may be late.

The most reliable way to detect colon cancer early is to undergo colon cancer screening.

Theoretically, everyone is likely to suffer from colon cancer, but the cost is a bit high and it is a waste of resources.

Therefore, screening for colon cancer mainly focuses on middle-aged and elderly people and high-risk groups.

Screening methods include a fecal occult blood test once a year and a colonoscopy every 10 years. In addition, you can also choose flexible sigmoidoscopy, colon CT, blood or stool DNA testing.

For high-risk groups with a history of adenomatous polyps, persistent inflammatory bowel disease, or first-degree relatives with colorectal cancer, screening should start early.
