Colon cancer: here's what to eat to avoid it

Regularly eating onions, garlic and leeks may reduce the risk of developing colon cancer, an extremely common disease in France.

While colon cancer is the second leading cause of cancer deaths in France, researchers have discovered foods that can reduce the risk of cancer. According to their study published this month in the journal Asia-Pacific Journal of Clinical Oncologygarlic, onion and leek would be preferred.

Onions, garlic and leeks

To come to these conclusions, Dr. Zhi Li and his colleagues at the First Hospital of China Medical University studied 833 patients suffering from this disease and as many healthy people. After dividing them by sex, age and place of residence, they periodically asked them about their eating habits and the frequency of their meals. They found that adults who ate a lot of onions, garlic and leeks were 79% less likely to develop colon cancer than others.

"It is worth noting that in our study, a trend emerged: the more the participants ate Allium vegetables, the more they were protected ... The research findings highlight a cancer treatment of the colon by a change of lifestyle and deserve additional research, "concludes Zhi Li.

Third most common cancer in France

In July, researchers had already made an astonishing discovery about colorectal cancer: drinking sodas with sweeteners would be associated with a better life. "Higher consumption of artificially sweetened beverages may be associated with a significant reduction in cancer recurrence and death in patients with stage III colon cancer (...)." For patients with colon cancer, and who find it hard to stop drinking sugary drinks, choosing sweeteners could save them the negative effects of sugary drinks, "the researchers wrote.

Colon cancer, a tumor that develops from cells lining the inner lining of the colon and rectum, is extremely common in the West. In France, it is the third most common type of cancer, all of which is common and occurs in the majority of people aged 50 and over.

Several treatments can be proposed

Depending on the stage of cancer, several treatments may be proposed: surgery alone in case of very localized lesion, surgical treatment with lymph node dissection and adjuvant chemotherapy when the disease has reached the ganglia, and surgery of the colon and metastasized organs in case metastases. The latter may be followed or preceded by chemotherapy or even targeted therapy.

Fortunately, however, mortality from colon cancer has been steadily decreasing since 1990, thanks in particular to better access to screening (colorectal cancer is asymptomatic, it is important to be screened every two years from the age of fifty). According to the latest figures from the National Cancer Institute (INCA), it has decreased by 1.5% per year on average for men and 1.1% per year on average for women between 2005 and 2012.
