Prostate cancer: abdominal obesity "promote the development of dangerous tumors"

For several years, many studies have shown that obesity seems to increase the risk of cancer. This new study of the Canadian National Institute for Scientific Research (INRS) more specifically underlines an association between abdominal obesity and an aggressive form of prostate cancer, relays Radio Canada.

According to this study, men who have been obese all their lives and who have obesity in the abdomen in adulthood appear to be at greater risk of developing aggressive prostate cancer.

Marie-Élise Parent, the professor who accompanied the work of doctoral student Éric Vallières, explains to the Canadian media that obesity increases hormonal levels. Because the prostate is an organ that is hormone dependent, severe obesity could reduce testosterone levels and lead to chronic inflammation. Inflation which can promote the development of dangerous tumors.

To carry out this study, the researchers questioned nearly 2,000 men – some of whom had had prostate cancer – from the Montreal region about their weight in adulthood, their waist circumference and the circumference of their hips. It appears that men with a larger waist circumference were more at risk of developing aggressive prostate cancer. This is particularly marked in people who have been obese all their lives.

Ms. Parent confirms that a person “who has been obese all his life and in addition, as an adult, has obesity that is markedly abdominal had an increased risk of aggressive prostate cancer. And obviously aggressive prostate cancer is the one that we of most interest in terms of prevention because it is associated with a worse prognosis. “

Researchers hold important information, because the risk factors on which one can influence are rather unknown for this type of cancer.
