Can intestinal polyps turn into cancer? Which intestinal diseases are likely to cause intestinal cancer?

Intestinal cancer is another name for colorectal cancer, which also includes rectal cancer and colon cancer. Because the early symptoms are not obvious or asymptomatic, they are often ignored by people. Then as the disease progresses, they gradually appear. When they are discovered, it is usually too late, which buries a fatal hidden danger for people who usually ignore their health. In order to avoid this situation from happening on a large scale, everyone should pay attention to their physical health and see a doctor in time if related abnormal symptoms occur. Especially those with these intestinal diseases should be more careful about cancer.

Which intestinal diseases are likely to cause colon cancer?

1. People with intestinal diseases

For example, patients with colorectal polyps, which are growths that grow from the intestinal mucosa, will increase with age. There are many types of polyps, the most dangerous of which are adenomatous polyps, which need to be removed in time, otherwise they can easily become cancerous. In addition, patients with schistosomiasis, the eggs of schistosomes will exist in the colorectal mucosa for a long time, which can also stimulate the intestinal mucosa and cause cancer. Finally, there are patients with ulcerative colitis, which can cause patients to have repeated bloody stools, and the chance of cancer is five to ten times higher than that of normal people.

2. People who have received pelvic radiation therapy

Patients with uterine and ovarian cancer often have to undergo radiotherapy. The incidence of rectal cancer in these people is four times higher than that of normal people, especially those who have received radiotherapy ten years ago or with a larger dose.

3. Patients who have previously suffered from colorectal cancer

Between 2% and 11% of colorectal cancer patients develop a second primary colorectal cancer after treating the first cancer. This phenomenon is called metachronous multiple cancer. Therefore, colorectal cancer patients should not rest assured just because they have been treated, but should undergo regular check-ups.

What are the symptoms of bowel cancer?

1. Blood in the stool is likely to occur

A common symptom of colorectal cancer is bloody stools. Colorectal cancer can cause secondary infection of the intestines, which will lead to narrowing of the intestinal lumen. Severe patients may even experience intestinal deformation. Over time, the intestines are no longer suitable for the excretion of feces, the quality of intestinal epithelial cells decreases, and the intestines are easily damaged due to long-term friction. This is also the root cause of bloody stools in patients with colorectal cancer.

2. Weak digestion and absorption capacity

The invasion of cancer cells can damage healthy cells in the intestines, and the patient's digestion and absorption ability will also be greatly reduced. Some colorectal cancer patients have digestion and absorption abilities that are even worse than children. This also shows that the patient's intestinal flora has been damaged, and the redox reaction rate in the intestine is very low. Patients usually do not need to defecate for several days.

Warm reminder: People who suffer from the above-mentioned intestinal diseases must actively treat the original disease and prevent cancer. In addition, they should go to the hospital for a physical examination every six months or a year. If any abnormalities occur, they should seek medical attention as soon as possible. This will reduce the incidence of colorectal cancer and improve the diagnosis and cure rates of colorectal cancer.
