Cancer is caused by genetic changes that break down normal constraints on cell growth.
It is known that obesity and being overweight increase the risk of developing cancer, but the question until now has been why?
In a new study from the University of Bergen, researchers found that lipids linked to obesity make cancer cells more aggressive and likely to form actual tumors.
They discovered that the changing environment surrounding the cancerous cell, from a normal weight body to an overweight or obese body, pushes the cancer cell to adapt.
This means that even in the absence of new gene mutations, obesity increases the risk that tumors will form.
Obesity is the cause of approximately 500,000 new cancer cases each year—a number that is expected to grow as obesity rates continue to increase.
The team says to scientifically dissecting how these two complicated diseases interact has been extremely interesting and rewarding.
Especially as this new understanding will enable researchers to design improved treatments for obese cancer patients.
If you care about cancer risk, please read studies about common vitamin that is very important for cancer prevention, and daily food that is directly linked to cancer risk.
For more information about health, please see recent studies about vegetable that could help lower your cancer risk, and results showing this stuff in avocado may help treat blood cancer.
The study is published in Nature Communications. One author of the study is associate professor Nils Halberg.
