What are the early symptoms of colon cancer

At present, colon cancer is a type of cancer with a relatively high incidence rate. Severe colon cancer can even threaten life. Therefore, for this disease, we must detect and treat it early. So what are the symptoms when colon cancer is in its early stages? Let's find out together.

1. After suffering from intestinal cancer, patients are prone to obstruction. Because the cancer infiltrates around the intestinal wall, the intestinal cavity is narrowed, especially at the junction of the rectum and sigmoid colon, which is mostly a narrow type of hard cancer, which is easy to cause obstruction. Patients with advanced rectal cancer will have some systemic cachexia and unexplained anemia or weight loss, fatigue, and loss of appetite due to long-term chronic consumption of the disease. Patients must pay attention to it in time and go to a professional hospital for examination and treatment.

2. Obvious changes in stool shape are also one of the early symptoms of colorectal cancer. Due to the intestinal irritation symptoms caused by the rectal mass and its secretions, patients experience frequent bowel movements, incomplete bowel movements, and feelings of tenesmus, but the discharge is mostly mucus, pus, and blood, accompanied by changes in stool shape, and the stool becomes thinner and thinner. Once colorectal cancer reaches the late stage, it often invades surrounding tissues and organs, such as the bladder and prostate, causing patients to urinate frequently, urgently, and have difficulty urinating. If the lesion invades the presacral plexus, sacral and lumbar pain may also occur.

3. Some patients may also experience abnormal symptoms of anal pain and anal incontinence. This is mainly due to the local pain caused by the infiltration of the lower rectal cancer into the anal canal, so anal incontinence may occur. Bloody stools also occur frequently, and often contaminate our underwear. Therefore, we should pay attention to this phenomenon.

Colon cancer can cause great harm to patients. Therefore, if the above-mentioned symptoms appear, do not take it lightly. It is best to go to the hospital for examination as soon as possible and receive treatment when the disease is in the early stages, which will greatly shorten the recovery time.
