Current study: Very thin people have a significantly higher risk of colorectal cancer

Lean people with high insulin levels have a greater risk of colorectal cancer
In general, obese and obese people are at an increased risk of developing various diseases. But a healthy body weight is no guarantee for a flawless health. Researchers found that thin people may look healthy but still have an increased risk of colon cancer.

Researchers from the International Agency for Research on Cancer( IARC) in France found that thin people may be healthy but sometimes have a significantly higher risk of developing colorectal cancer. This is related to an increased insulin level. The physicians published the results of their study in the journal "Public Library of Science Medicine".

blood level measurement can improve colorectal cancer diagnosis and treatment

Abnormal insulin levels are associated with an increased risk of colorectal cancer, regardless of individual obesity, say the authors. The results suggest that blood level measurement could help identify the disease. This will increase the likelihood of early diagnosis and treatment, the researchers add.

Watch out for insulin levels to prevent colorectal cancer
These results show for the first time that the risk of colorectal cancer is linked to an increase in insulin levels in lean people, but also in people with obesity.

Unhealthy diet and lack of exercise couldCause
There are often high levels of insulin in overweight people. Lean people are less likely to have elevated insulin levels, explain the authors."We do not know exactly why even thin people can have an elevated insulin level," the researchers continue. A wrong diet or lack of exercise could be due to the increased insulin levels, so the scientists guess.

Insulin levels and BMI help assess colorectal cancer
Measurements of insulin levels may be used alongside the so-called BMI( Body Mass Index) as a new tool to assess the risk of colorectal cancer. For this, however, we need stronger surveillance. In general, many of the cases of colon cancer could actually be prevented by a healthy lifestyle, explain the doctors. Prevention could be even easier if they are regular coffee drinkers. Because researchers have already determined in earlier investigations that coffee can reduce the risk of colon cancer.

Physicians Examine the Level of C-Petid
The study was part of the large European Prospective Investigation into Cancer and Nutrition Survey( EPIC).The subjects included 737 participants with colorectal cancer and the same number of people without the disease, the researchers explain. The physicians examined the subjects in the levels of a so-called insulin biomarker, the so-called C-peptide.
Take care of healthy diet and exercise
The interesting new findings allow us to identify the populations of the population most at risk for colorectal cancer, say the authors. In general, it is very important to pay attention to a healthy diet and exercise regularly. This not only helps reduce the risk of colorectal cancer, but also protects against a variety of other cancers, explain the physicians. It is also known that, for example, fat fish protects against colon cancer and even inhibits tumor growth.
