Interpretation: Can you run if you have colorectal cancer?

A statistic conducted by the Department of Oncology shows that in the past two years, 4 to 5 out of every 100 colorectal cancer patients in the department were under the age of 35. The proportion of young people suffering from colorectal cancer continues to rise, and more men than women. Many young people rarely exercise. If they have colorectal cancer, proper running can help their health. So why are people who rarely exercise more likely to get colorectal cancer?

First, less physical activity does not stimulate colon peristalsis, thereby increasing the retention time of food factors, endogenous bile acid and carcinogens in the colon;

Second, less physical activity can reduce the level and function of T cells, B cells, natural killer cells and interleukin I in the body, which is not conducive to killing cancer cells in the body;

Third, people with a higher body mass index participate less in strenuous physical activities, which is not conducive to maintaining an internal environment in the body that is not conducive to the growth of cancer cells (lower levels of insulin, blood sugar and triglycerides) and is conducive to the growth of colon cancer cells.

Who is more likely to develop bowel cancer?

1. Patients with colorectal polyps: Polyps are mainly divided into two categories: adenomatous and hyperplastic (inflammatory). It is known that adenomatous polyps, especially multiple polyps, are prone to canceration. The incidence of colorectal cancer in patients with adenomatous polyps is 5 times higher than that in patients without adenomas! In particular, large adenomas with a diameter greater than 1 cm are more dangerous. Therefore, adenomatous polyps are called "precancerous lesions of colorectal cancer" and must be removed completely to prevent future problems. Even after removal (including surgical resection), we should still be vigilant against recurrence. Inflammatory polyps have a lower chance of becoming cancerous.

2. Patients with ulcerative colitis: The risk of cancer in patients with ulcerative colitis is 5 to 10 times higher than that in normal people. If the disease occurs before adulthood, the lesions are always active and widespread, and the disease lasts for more than 5 years, the risk of cancer is even greater.

3. Those who have received pelvic radiotherapy: Most of them are patients with ovarian and uterine cancer. Their incidence of rectal cancer is 4 times higher than that of the general population. Rectal cancer usually occurs 10 years after radiotherapy, especially in patients with a large dose of radiotherapy.

4. Those with a family history of colorectal cancer: The incidence of colorectal cancer in those with a family history is three times higher than that in those without a family history, which may be related to the same eating habits.

5. Patients who have undergone cholecystectomy: After cholecystectomy and proximal and distal small intestine anastomosis, the toxic secondary bile acid directly enters the colon and stimulates the intestinal mucosa, increasing the risk of developing colon adenomatous polyps and cancer.

6. Those engaged in certain occupations: such as asbestos processing industry and textile industry workers.
