About 1 million new cases of colon cancer are diagnosed worldwide every year, and about 500 thousand patients die each year from this disease. Colon and rectal cancer is a malignant tumour of the colon, which is the third most common. The life expectancy of patients with colon cancer is directly related to the degree of prevalence of the tumour process.
Despite the high mortality rate from colon cancer, the disease is treatable with its early diagnosis. Regular examinations, blood tests, colon examinations (colonoscopy) are recommended for the determination of precancerous polyps and colon cancer at a first stage. As a preventive measure of pathology, it is also possible to cleanse the body of toxins and harmful substances using a colonic hydrotherapy procedure regularly.
Treatment of colon and rectum cancer
The choice of treatment method is based on the assessment of the tumour process stage, tumour localisation, the specific features of the tumour’s tissue structure, and the patient’s physical condition.
The primary treatment method is surgical. In the absence of distant metastases, a basic operation is performed, during which a tumour is removed along with the affected tissues and regional lymph nodes to prevent metastasis. Surgical treatment can be combined with radiation therapy and chemotherapy.
Radiation therapy is treatment with ionising radiation. Radiation therapy is often used as an additional method of surgical procedure and chemotherapy to reduce the risk of cancer recurrence.
Chemotherapy in oncology of the intestine refers to the methods of general exposure, which distinguishes it from surgery and radiation therapy. This type of treatment is used for various purposes: to destroy cancer cells, suspend tumour growth for a long time, reduce the size of a tumour before surgery or radiation therapy, and destroy micrometastases that could appear before or after removal of a tumour.
Chemotherapy for bowel oncology is one of the most effective treatments. Preparations used for chemotherapy have a destructive effect on tumour cells. Chemotherapy is always a course of treatment.
Postoperative chemotherapy for bowel oncology is used to reduce the risk of recurrence and progression of the disease.
A patient with an intestinal tumour, who was operated on, after the operation must consult an oncologist for the proper selection of postoperative chemotherapy and prevent the development of a tumour in the future.
