Cancer’s Secret Fuel Source, Finally Exposed
You already know that being overweight or obese increases your risk of major issues like heart disease, type 2 diabetes, sleep apnea, and joint problems.
But did you know those extra pounds also fuel your cancer risk?
Obesity is strongly linked to 13 types of cancer—and some research indicates it could be tied to as many as 30 different kinds.
Now, researchers finally may have uncovered the missing link between obesity and cancer…
It turns out that fat cells are one of cancer’s favorite foods.
Using human tissue, researchers evaluated fat cells at various distances from breast tumor cells. They found that the cells closest to the tumors were the most depleted in lipids.
The tumors inserted microscopic “straws” into fat cells to drain their lipids—supercharging tumor growth and spread.
In other words, breast cancer cells transform nearby fat into an all- you-can-eat energy buffet.
But when the researchers blocked the tumor’s ability to create these “straws,” they effectively STOPPED the growth of the tumors.
The same results were found in mouse models of breast cancer.
The study used an aggressive type of cancer called triple-negative breast cancer, which has lower survival rates.
However, it’s possible (and even likely) that this exact mechanism is at play in other cancers that are connected to overweight and obesity.
This study suggests that blocking tumors from making and using these “straws”—essentially cutting off their food supply—may hold the key to halting aggressive cancers.
Certain medications already exist that work in this manner, and studies are underway to determine their effectiveness against cancer.
In the meantime, there’s something you can do right now to lower your risk—or to improve your odds if cancer ever strikes…
Lose weight!
Starve these glutenous cancer cells by cutting off their all-you-can-eat buffet.
Studies show that even modest weight loss can lower your risk of cancers like breast cancer.
This could be a big reason why.
P.S. Your do-it-yourself “prescription” for cancer survival.
