According to WHO data, colon cancer is one of the five most common types of cancer worldwide. In France, the risk of this cancer is very high, it is the most common malignant tumor and the second leading cause of cancer death in this country. What are the symptoms of this type of cancer and how can it be prevented? We explain everything.
Colon cancer is a malignant tumor that forms in the colon. It is generally developed from polyps, from the excrescences present in the walls which line the colon. These are often benign, but some of them can become cancerous.
Colon cancer affects mainly people over 50 years old, those suffering from inflammatory bowel disease, or who have a personal or family history. But although older people are more at risk, those younger can also be affected.
Risk Factors and Symptoms of Colon Cancer:
The appearance of colon cancer can be promoted by various factors such as obesity, sedentary lifestyle and poor diet. Its symptoms, which are rather discrete, manifest only during the later stages of the disease. Blood in the stool, weight loss or abdominal pain, among others.
Cancer of the colon, how to prevent?
To reduce the risk of colon cancer, it is important to adopt a healthy lifestyle. Here are some tips that will help you prevent this disease:
Eat more fruits and vegetables:
In addition to providing essential nutrients for the body's proper functioning, fruits and vegetables also provide plenty of antioxidants and fiber. Antioxidants are highly recognized for their ability to fight free radicals that damage the body's cells and cause various diseases including cancer.
Fibers are essential for good digestion and can also play a protective role against colon cancer. In fact, fibers present in the colon can prevent the occurrence of colon cancer by reducing the time of contact of the carcinogenic toxins present in the stool with the mucosa. And although studies diverge as to the protective effect of dietary fiber, a diet rich in these substances is highly recommended!
Magnesium, which is found in abundance in different fruits is also known for its anti-cancer properties. According to a study conducted by researchers at the University of Wageningen, an additional 100 mg of magnesium, reduces the risk of colon cancer by 12%.
Have a sufficient intake of vitamin D:
According to a meta-analysis published in the Journal of Clinical Oncology, high intakes of vitamin D and high levels of this vitamin in the blood can reduce the risk of colorectal cancer.
The results of the study showed that people with high levels of vitamin D were 33% less likely to develop this cancer, while those who consumed high levels of vitamin D reduced their risk by 12%.
Verdict: consume foods rich in vitamin D and expose yourself to the sun regularly!
Avoid red meat and processed meats:
Red meats have interesting nutritional values because they are high in protein, zinc and iron ... but consuming them excessively can increase the risk of colon cancer.
Indeed, according to various scientific studies, red meat has highlighted positive associations between the appearance of colorectal cancer and the consumption of red meats. In fact, WHO has classified them as likely to be carcinogenic to humans. Processed meat and deli meats, on the other hand, have been classified as carcinogenic to humans.
The harmful effect of sausages and red meats lies in their methods of cooking and preparation. Deli meats are often rich in additives and dyes that can be toxic, while cooking red meat at high temperatures (barbecue) promotes the formation of carcinogenic substances such as polycyclic aromatic hydrocarbons.
It is therefore recommended to avoid processed meat and limit its consumption of red meats (300 to 500 g per week).
Practice sports :
Doing a regular sports activity is essential to maintain a healthy weight and prevent obesity, which is part of the risk factors for colon cancer. In addition, sport facilitates intestinal transit, which reduces the exposure time of the colon walls to carcinogenic substances from the diet, and influences the inflammatory parameters. Recall that chronic inflammation plays a role in the onset of colon cancer.
- Other tips to prevent colon cancer:
- Avoid smoking and limit alcohol consumption
- Consume more seeds and nuts for good fats
- Eat more garlic and onions for anti-cancer effects
- Avoid fried foods that are high in fats and sugars
