How fat cells boost cancer tumour growth

0 Comments

We’ve known for a while that carrying extra weight can raise your risk of cancer. But a new meta-analysis shows why.

According to a new study, the extra fat that you carry around your waist doesn’t just make you put away your skinny jeans for the winter, but also increases your risk of cancer!

One more reason to lose the love handles

This latest meta-analysis, published in Cancer Prevention Research, reviewed 20 studies on the relationship between fat cells and cancerous tumours.

The results showed that certain fat cells, called “adipose stromal cells”, and cancer cells engage in what’s known as “crosstalk”. This means that the two types of cells exchange chemical “signals” with one another. As a result, the fat cells encourage the cancer cells to grow must faster.

The study also found that obese people with cancer have more of these fat cells in their bodies than leaner people — suggesting that being too heavy around the midriff can put you at a higher risk of developing cancer.

In fact, the researchers found that different types of cancers — like colon, rectal, and breast cancers — develop right next to fat deposits, supporting the theory that excess fat cells can contribute to an increased cancer risk.

Previous studies have also shown that obesity increases inflammation throughout your body and undermines your immune defences, both of which can help cancerous tumours grow and spread.

Carrying extra weight can hijack your hormones and increase your insulin levels. So, to maintain a healthy weight and keep cancer at bay, don’t fall for the high carb and sugar laden temptations of the season.

Instead, stick to a diet that eliminates grains, sugars, and processed foods while focusing on fresh foods like fruits, vegetables, fish, meat, nuts, and seeds.
