El exceso de peso, ligado a un mayor riesgo de mortalidad entre los pacientes de cáncer de mama y colon.
Today we echo a news article published by the international cancer research organization WCRF (World Cancer Research Fund.) who has pointed out how the body mass index (BMI) and cardiometabolic disease (CMD) have a direct link with the survival rates of adult patients with colorectal and breast cancerboth BMI and CMD independently, according to research published by the World Cancer Research Fund last month.
Researchers from IARC and Universität München found that for BMI, for each unit (kg/m2) Additionally, there is a significant association with the risk of dying from those causes of cancer (breast and colorectal: the most common cancer in the world and the third most common cancerrespectively).
The research, which was published in the magazine BMC Cancerstudied a European cohort of 159,045 patients tracked between 1992 and 2000. The findings show that for adults aged 20 to 50 years, an increase in BMI of 1 kg/m2 It meant a 6% increase in the risk of death for patients with colorectal cancer. For breast cancer patients, for every 1 kg/m increase2 in BMI there was a 4% increase in the risk of death.
Direct effect of BMI.
The findings also showed that although a history of cardiovascular risk (as in the case of type 2 diabetes and other metabolic syndrome pathologies) is associated with a 46% increase in the risk of death, it is BMI that has a Direct effect on cancer survival, regardless of whether the individual also has diabetes or other pathologies.
The study’s author, Dr. Heinz Freisling, notes that: «This multicenter study was conducted to further explore the relationship between comorbidities and cancer survival. Surprisingly, both BMI and CMD have been found to have a direct relationship with survival outcomes independently of each other for patients with colorectal and breast cancer. This suggests that the increased risk of death among overweight or obese patients cannot be explained by comorbidities alone.«.
Our Diet, our health.
In any case, studies like this one reinforce the role of a healthy life style (diet, especially the Mediterranean diet, and physical activity) in the prevention and treatment of chronic pathologies such as cancer.
