Can the feces of patients with intestinal cancer be contagious?

Colorectal cancer is the fastest-growing cancer in my country, and the number of young and middle-aged patients has increased significantly. Is colorectal cancer contagious? Why does the risk of developing colorectal cancer increase when a family member has it? It turns out that among the various risk factors of colorectal cancer, the most direct one is diet. So, is the feces of colorectal cancer patients contagious? The answer is of course no. Let's take a closer look.

Data show that a diet high in fat, animal protein, refined carbohydrates, and fiber promotes colorectal cancer. In addition, eating smoked, grilled, and fried foods, drinking strong alcohol frequently, and long-term lack of exercise, constipation, overweight, and obesity increase the risk of colorectal cancer. It can be said with certainty that colorectal cancer is caused by eating.

Fiber-rich foods can prevent colon cancer

Dietary fiber is called "nutritional without nutrition" by nutritionists because its role cannot be replaced by other nutrients. Without dietary fiber, feces will stay in the intestine for a longer time, causing the intestine to reabsorb waste, resulting in carcinogens in the feces irritating the intestinal wall for a long time. Therefore, cellulose is called the cleaner of the intestine. It is like a small brush, promoting intestinal peristalsis, cleaning garbage and waste in the intestine, reducing the residence time of intestinal carcinogens, and thus reducing the risk of colorectal cancer.

The American Cancer Society recommends that each person consume 30 to 40 grams of dietary fiber per day; the standard daily intake for people under 70 years old in Japan is 19 to 27 grams; the standard recommended by my country is 30 grams of dietary fiber per day.

So, how many grams of fresh fruits and vegetables contain 30 grams of dietary fiber? Generally speaking, it is equivalent to about 10 apples, 19 bananas, 4 pounds of celery, 6 tomatoes, etc. Obviously, it is difficult for ordinary people to achieve such an intake. However, eating more fiber-rich foods, even if it does not reach the standard amount, will play an important role in preventing colorectal cancer.

In addition, whole grains such as corn, millet, barley, wheat bran (rice bran) and wheat flour (the material of black bread) are rich in fiber; vegetables such as carrots, green beans, peas, and potatoes are also high-energy foods containing cellulose. This is why sweet potatoes are called the champion of anti-cancer foods. Therefore, eating more potatoes, fish and bean products, especially whole grains such as wheat and bran-preserved flour, which are high in fiber, are beneficial to preventing colon cancer.

Therefore, couples and family members may suffer from colorectal cancer at the same time because they all have the same eating habits and unhealthy lifestyles, which imperceptibly damage the health of both parties. To prevent colorectal cancer, we must first start with eating habits.
