Three symptoms indicate colon cancer

Colorectal cancer refers to malignant tumors that occur in the colon or rectum. The incidence of colorectal cancer is closely related to factors such as lifestyle, genetics, and colorectal adenoma. There are more than three symptoms of colorectal cancer, but usually there will be changes in bowel habits, bloody or black stools, abdominal pain or discomfort, weight loss, intestinal obstruction, and abnormal intestinal function. It is recommended to seek medical attention in time for relevant examinations. The details are as follows:

1. Changes in bowel habits: including constipation, diarrhea, or changes in bowel movement frequency. Bowel movements that last longer may be a sign of colon cancer.

2. Bloody or black stools: Bowel cancer may cause bright red or dark red blood in the stool, or the stool may appear black and tarry. This is caused by tumor bleeding or ulcer formation.

3. Abdominal pain or discomfort: Intestinal cancer can cause abdominal pain, discomfort or cramps. The pain may be related to the location, size and spread of the tumor.

4. Thinness and weight loss: If colon cancer causes loss of appetite, malabsorption or metabolic changes, patients may experience unexplained weight loss and thinness.

5. Intestinal obstruction: When intestinal cancer forms a mass or obstruction in the intestine, it may cause intestinal obstruction. Obstruction symptoms include abdominal distension, nausea, vomiting, decreased or absent bowel sounds, etc.

6. Abnormal intestinal function: Colorectal cancer may interfere with normal intestinal function, leading to intestinal gas accumulation, abdominal distension, abnormal bowel sounds, etc.

If one or more of the above symptoms occur and last for a long time, it is recommended to seek medical attention in time to check whether it is caused by colorectal cancer. Colorectal cancer requires colonoscopy, pathological biopsy and other clear diagnosis. After a clear diagnosis, surgical resection, radiotherapy, chemotherapy and other measures can be performed under the guidance of a doctor. Surgical resection is one of the main methods for treating colorectal cancer, and radiotherapy and chemotherapy can be auxiliary treatments. Early detection and diagnosis of colorectal cancer can improve cure and survival rates. It is also very important for high-risk groups to perform regular colorectal cancer screening.
