In recent years, with the changes in people’s lifestyle and diet, the incidence and mortality of colorectal cancer in my country have shown a trend of increasing year by year, with 388,000 new cases and 187,000 deaths each year. The early diagnosis rate of colorectal cancer is very low, and most patients are already in the advanced stage when they are diagnosed. Fortunately, the emergence of precision treatment methods such as targeted and immunotherapy have effectively prolonged the survival of patients with metastatic colorectal cancer, prolonged the life of patients through scientific treatment, and improved the quality of life of patients.
Be alert to changes in bowel patterns
Colorectal cancer is a malignant tumor. Generally, there are no obvious symptoms in the early stage. As the disease progresses, there will be changes in defecation rules, such as frequent or significantly reduced frequency, alternating constipation and diarrhea, unexplained symptoms such as anemia, blood in the stool, weight loss, and abdominal masses. Many patients have already entered the advanced stage of cancer when they are discovered, and have missed the best time for treatment.
Therefore, high-risk groups of people over 50 years of age, with a history of colorectal polyps or colorectal cancer, chronic enteritis, long-term drinking or high-fat diet, long-term sitting and working and lack of exercise can undergo colonoscopy once every 5 years. Perform 1 stool occult blood examination and digital anal examination. If you find intestinal polyps, you must pay attention to it, because 80% of colorectal cancers are evolved from polyps. It takes about 3 to 5 years from polyp to cancer. If treatment can be carried out before cancer, tumor can be effectively prevented.
Surgery is the main treatment
At present, the treatment of colorectal cancer is mainly based on surgery, and this is the only way to cure colorectal cancer. With the development of medical technology, great progress has been made in colorectal cancer surgery in recent years. It can also improve intestinal function while removing tumors and effectively improve the quality of life of patients after surgery. In addition, according to the different conditions of the patients, there are chemotherapy, targeted therapy and immunotherapy.
Surgical treatment mainly includes 3 methods: traditional surgery, palliative surgery and laparoscopic surgery.
Traditional surgery generally focuses on resection of part of the colorectal and part of the anus. The selection is based on the location of the patient’s lesion and the extent of cancer spread. If necessary, invasive surgery is required. Although the effect of traditional surgical treatment is good, it has certain shortcomings. During the operation, the patient has a large amount of bleeding, infection is more likely to occur after the operation, and the postoperative recovery period is long.
Laparoscopic surgery is currently the main method of clinical treatment. Although according to clinical statistics, laparoscopic surgery does not significantly reduce the recurrence rate and mortality after surgery, but the mechanical damage during the operation is relatively small, and the patient’s surgery The recovery is faster and the probability of complications is lower.
Palliative surgery is significantly different from the above two surgical methods. The first two surgical methods are aimed at curing, while palliative surgery is mainly non-radical resection for patients with excessive tumor invasion, and its main purpose is to extend The life of the patient reduces the suffering of the patient.
Chemotherapy is mainly for patients with advanced colorectal cancer and postoperative treatment. Oxaliplatin or irinotecan are generally the mainstay. The two effects are basically the same and can be used interchangeably.
Targeted therapy is a new type of treatment that has emerged in recent years. It is not effective for all patients. It is necessary to perform genetic testing on patients to determine whether it is suitable for targeted therapy. Targeted therapy will target the lesion and rarely cause damage to other normal cell tissues on the basis of killing cancer cells. It is an ideal treatment method.
As an innovative cancer treatment method, tumor immunotherapy does not directly attack cancer cells, but fights tumors by activating the body’s own immune system. It is a good auxiliary method for the treatment of colorectal cancer.
Improve diet and stay away from colorectal cancer
In daily life, you need to do the following to stay away from colorectal cancer:
First, regular physical examinations. Health check-ups should be based on personal physical conditions. It is best to do it once every six months or at least once a year. The main organs such as heart, liver, kidney, brain, lung, rectum, prostate or gynecology should be checked.
Second, pay attention to diet. Insufficient intake of dietary fiber, the residence time of feces in the intestine will be longer, and the intestine will absorb wastes again, causing carcinogens in the feces to stimulate the intestinal wall for a long time. Cellulose can promote intestinal peristalsis, clean garbage and waste in the intestine, reduce the residence time of carcinogens, thereby reducing the risk of colorectal cancer.
Finally, work harder. Exercise can help improve the body’s immunity and prevent the invasion of various bacteria and viruses. In daily life, we must develop good exercise habits, so as to help everyone stay away from colorectal cancer.
