Is intestinal malignancy colon cancer?

Intestinal malignancy is colorectal cancer, which is a malignant lesion that occurs in the intestine and may involve the colon, rectum and other parts. The occurrence of intestinal malignancy is closely related to genetics, environment, lifestyle, chronic inflammation and other factors. Early detection and treatment are crucial to prognosis.

1. The causes of intestinal malignant tumors include genetic factors, environmental factors, physiological factors, trauma and pathological factors. Among genetic factors, familial adenomatous polyposis and hereditary non-polyposis colorectal cancer are common types of hereditary colorectal cancer. Among environmental factors, unhealthy lifestyles such as high-fat and low-fiber diets, smoking, and drinking will increase the risk of disease. Among physiological factors, aging, obesity, diabetes, etc. will also increase the probability of disease. Traumatic factors such as intestinal surgery or inflammatory bowel disease may cause intestinal tissue damage, thereby increasing the risk of cancer. Among pathological factors, chronic inflammatory bowel disease, intestinal polyps, etc. are common precancerous lesions.

2. Treatments for intestinal malignancies include surgery, drug therapy, and radiotherapy. Surgery is the main method, and common surgical methods include segmental resection, total colectomy, and proctocolectomy. Drug therapy includes chemotherapy, targeted therapy, and immunotherapy, and commonly used drugs include 5-fluorouracil, oxaliplatin, and bevacizumab. Radiotherapy is often used for rectal cancer, using high-energy rays to kill cancer cells or inhibit their growth.

3. Prevention of intestinal malignancies needs to start with lifestyle and eating habits. In terms of diet, increase dietary fiber intake, such as eating more vegetables, fruits and whole grains, and reduce the intake of red meat and processed meat. In terms of exercise, maintain at least 150 minutes of moderate-intensity exercise per week, such as brisk walking, swimming or cycling. Regular physical examinations, especially for people over 50 years old, are recommended for colonoscopy to detect and treat intestinal polyps or precancerous lesions at an early stage.

The early symptoms of intestinal malignancies are not obvious, but they may include blood in the stool, abdominal pain, weight loss, etc. Once related symptoms are found, you should seek medical attention in time and make a clear diagnosis through colonoscopy, CT and other examinations. Early diagnosis and comprehensive treatment are the key to improving survival rates. In daily life, maintaining a healthy lifestyle and regular physical examinations can help reduce the risk of disease.
