What are the preventable causes of colon cancer and how to prevent it?

Did you know that most of the causes of colon cancer can be easily prevented by following a healthier lifestyle and a healthy diet? We will discover which ones.

It is estimated that each year are diagnosed about 140,000 new cases of colorectal cancer, among which is the cancer of colon and rectal cancer. While, in our country, colon cancer is considered one of the malignant tumors with the highest incidence, with figures ranging between 28,500 and 33,800 cases each year..

It is, as they warn, a type of malignant tumor whose incidence is increasing alarmingly, especially in western and developed countries, while in Spain the 5-year survival after diagnosis is 64% (somewhat higher than the average European). However, it is a cancer whose cure rate is high if detected early, especially since it tends to take a long time to develop.

Colon cancer is a disease that usually appears on an existing polyp in the mucosa of the colon, which for different reasons evolves into a malignant tumor. Malignant cells are usually located in the longest part of the large intestine, as well as in the middle portion.

As you surely know, the colon is the place where stool is stored before being expelled to the outside through the anus. That is to say, it accumulates waste substances, making it a place that is certainly conducive to the appearance of a malignant tumor.

It is a type of cancer that usually appears after the age of 40, so its incidence increases as the years go by. For this reason, the number of experts who request that the tests to detect it early be carried out at younger ages, instead of doing them from 50-55 years.

Among the tests most commonly used for early detection, the Cancer Society advises performing a CT colon gram every 5 years, a colonoscopy every 10 years, a double-contrast barium enema every 5 years, or a flexible sigmoidoscopy test for 5 years. Years.

On the other hand, there are also other tests considered as effective as a colonoscopy, such as the fecal occult blood test or the fecal immunochemical test.

What are the main causes of colon cancer that can be prevented?

As immune scientific studies have already confirmed, as is the case with other types of cancers but in colon cancer with the highest incidence, colorectal cancer is closely related to the lifestyle and diet that we follow throughout our lives.

For this reason, there are some causes that can help prevent colon cancer. How?  Very simple: changing certain habits, improving our lifestyle and taking care of the diet that we follow every day.

Control overweight

Did you know that being overweight is related to colon cancer? In fact, a higher body mass index is known to be strongly associated with a higher risk of colorectal cancer.

Abdominal obesity due to the distribution of fat in the body appears to be an important factor.

It is as we see an easily avoidable and preventable cause. It is enough to change our diet, especially if we follow an unbalanced and unhealthy diet (that is, we consume foods high in fat and sugar), and opt for healthy, fresh and natural foods. Among these foods, fruits, vegetables and vegetables stand out, as they are rich in fiber.

Avoid constipation

The constipation is also a related cause with colon cancer. We must bear in mind that the colon is together with the rectum the place where feces are stored precisely before being expelled to the outside through the anus.

Therefore, it is important to reduce the accumulation time of feces in the large intestine, following a varied and balanced diet that helps and improves intestinal transit. A good option is to eat foods rich in fiber, such as whole grains, fresh fruits and vegetables, as well as nuts and legumes.

Among the cereals, oats, barley, rye and wheat germ and bran stand out. Also nuts such as almonds, hazelnuts and walnuts. On the other hand, other foods such as lentils, beans, peas and flax seeds stand out.

Eliminate cold cuts and reduce red meat

The intimately existing relationship between the habitual consumption of cold cuts, cold cuts (processed meats) and red meat with colorectal cancer is becoming clearer, increasing the risk and incidence the higher and more excessive their consumption is.

This was alerted by a report in which it considers processed meat as “carcinogenic to humans”, and red meat as “probably carcinogenic to humans”.

Get moving and avoid physical inactivity

Following a sedentary lifestyle favors the appearance of colon cancer. In fact, it is estimated that the probability of suffering from it increases by 8% when there is an increase of 2 hours of sedentary lifestyle per day.

The same is true of sedentary work, which can increase the risk of certain long-term chronic diseases, including colorectal cancer.

The solution? Although it is true that sedentary work is related to cancer risk despite physical exercise being practiced during free time, we must avoid sedentary lifestyle, practicing sports regularly every day.

Dietary Tips for Colon Cancer Prevention

  • Eat foods rich in fiber: foods rich in fiber are essential –and essential- in the prevention of this type of cancer, since it is a nutrient that facilitates intestinal transit and the expulsion of waste. In fact, they help because they reduce the time in which the waste (rich in toxic agents) is in contact with the intestinal wall. It also absorbs bile acids, thus preventing them from acting on bacteria to produce fecapentanes (carcinogenic substances that are formed once food has decomposed within the colon). Therefore, it is important to consume at least 25 grams of fiber a day.
  • Eat foods rich in calcium : calcium is a mineral whose daily consumption helps to have a lower incidence of colorectal cancer, since it  controls the multiplication of the epithelial cells that line the colon , which when they proliferate increases the risk of suffering from it. Opt for dairy products and derivatives, as well as vegetables, legumes, soybeans, nuts and fish.
  • Essential and protective vitamins: vitamin C stands out (blocks the formation of nitrosamines in the stomach, carcinogenic substances that are formed from nitrites and nitrates), vitamin D (eliminates the formation of new blood vessels that feed the growth of tumors) and vitamin E (in addition to being an antioxidant, it blocks the formation of carcinogenic substances in our body).

Causes that cannot be prevented

However, there are certain causes that cannot be prevented, especially in the presence of  familial colonic polyposis (affects 1% of colon cancers, appears during adolescence and causes multiple polyps in the clone and rectum, as a result of a mutation of the APC gene that is transmitted from parents to children), or hereditary no polyposis colorectal cancer (it accounts for 5% of tumors and occurs in patients who do not have polyps).
