The Secret Weapon Against Breast Cancer? (Boosts Survival 24%)

Let’s face it – if you’ve never had to tangle with breast cancer, you know someone who has.

There are about 380,000 American women diagnosed every year.

That’s more than the entire population of Cleveland.

And women endure the grueling treatments – like painful, disfiguring surgeries or brutal radiation – to give themselves every chance to beat the disease.

But surviving breast cancer may have just gotten a little easier…

Researchers have discovered a simple way to boost your odds of beating the disease by 24%.

Even better? There are NO harsh treatments required – and it takes just minutes a day.

Researchers from the Roswell Park Comprehensive Cancer Center, Buffalo, NY, recently followed more than 4,500 women who had been diagnosed with invasive breast cancer.

Whether they survived or not often came down to a surprisingly simple factor…

How were their vitamin D levels at the time of diagnosis?

Women with sufficient vitamin D levels were 24% more likely to survive their bouts with breast cancer.

Could something as simple as your vitamin D levels really give you that much of a boost against breast cancer?

Absolutely.

Vitamin D plays an essential role in supporting your immune system and controlling inflammation – two critical factors in your fight against any cancer.

If you or a loved one has been diagnosed with breast cancer, talk to the care team about this latest research and have their vitamin D levels checked.

As you know, I’d always rather you increase your vitamin D levels through regular sun exposure. Start with 5-10 minutes a day, with as much skin exposed as possible.

Then, try to increase your time in the sun by a few minutes each week.

But if you’re fighting breast cancer and your D levels are low, talk to your doctor about supplementing as necessary.
