The Breast Cancer Trigger Nobody Warns You About
There’s no doubt in my mind that the way we approach breast cancer in America is horribly backward.
We spend billions treating it… and not a dime preventing it.
Mainstream medicine will talk up a storm about the importance of “early detection” and mammograms.
But all that does is catch cancer after you have it.
How about we help women lower their risk of ever getting breast cancer to begin with?
Case in point? New research out of Texas is showing that a simple health problem… one that many women ignore… can send your risk of aggressive breast cancer soaring.
But here’s the good news – you can fix it and lower your risk of ever tangling with breast cancer.
And you can start today.
We’ve known for a long time that disruptions to your circadian rhythm – your body’s natural sleep/wake cycle – can increase your risk for cancer.
But for the first time, researchers at Texas A&M University saw it happen, in real time, with breast cancer.
Researchers took a group of mice genetically engineered to develop breast cancer, and then disrupted the circadian rhythms for some of the mice.
And that’s when all heck broke loose.
The mice with the circadian disruptions experienced:
- Weakened immune systems
- Changes to their breast tissue
- Cancer that developed 22% faster
- And tumors that were FAR more aggressive and likely to spread to their lungs
Could something as simple as a disrupted sleep/wake cycle really cause all of that damage?
You bet it could. Your circadian rhythm is essential to countless processes happening inside your body, including how well your immune system functions.
And that’s a big deal, because your own immune system is your best defense against cancer.
So how can you keep your circadian rhythm healthy and lower your breast cancer risk? Here are two steps you can take right away.
First, get sunlight in your eyes first thing every morning – no glasses or contact lenses. You don’t have to look directly into the sun – just keep it in your peripheral vision.
Second, avoid artificial blue light at night from TVs, computers, and cell phones. Your body mistakes this light for sunlight, which disrupts your circadian rhythm.
If you have to use these devices in the evening, wear glasses that block blue light glasses (they’re easy to find online for less than $20).
