How Genetics and Lifestyle Play a Role in Cancer Prevention
Let’s be honest—cancer is one of those words nobody wants to hear. But instead of letting it hang over us like a dark cloud, let’s flip the script and focus on what we can do. While we may not have all the answers about what causes cancer, we do know there are plenty of things you can do to lower your risk. From the foods you eat to avoiding everyday toxins (looking at you, bologna), small changes can add up in a big way. So why wait? It’s time to get proactive and take control of your health, starting today.
What Exactly is Cancer?
In simple terms, cancer is the uncontrolled growth of abnormal cells in the body. Under the right conditions, these cells can multiply without limits, which can ultimately be life-threatening. And while it feels like cancer is everywhere these days, the good news is that survival rates are improving. We’re seeing a modest decline in cancer death rates, meaning you're now less likely to die from cancer if diagnosed.
How Can I Reduce My Risk?
I’m so glad you asked! While we don’t know exactly what causes cancer, we do know there are several risk factors that increase your chances. Here’s a quick rundown of what to watch out for:
Smoking: Seriously, people still do this? Avoid it.
Pesticides: Think organic where possible. Not sure where to start? Check out the Dirty Dozen and for the most important foods to buy organic.
Processed Meats: Yes, that bologna (thanks, Oscar Mayer!) increases your risk of colon cancer. Time to toss it.
Formaldehyde: Used in some furniture manufacturing and medical procedures. Before buying new furniture or cosmetics, double-check it wasn’t part of the process.
Radon: If you haven’t tested your home for this, do it! Radon exposure is the top cause of lung cancer in non-smokers. You can find test kits at the hardware store or hire professionals.
Alcohol: It’s a known carcinogen. The more you drink, the higher your risk for cancers like head, neck, esophageal, breast, liver, and colorectal. Keep it in check.
Burnt Foods: Yes, even those crispy BBQ burnt ends can be harmful. They contain heterocyclic amines, which aren’t great for your digestive system or your immune function. So, good luck with that one.
Genetic Predispositions
Some people have a higher cancer risk due to their genes, like the well-known BRCA genes for breast and ovarian cancers. But beyond BRCA, there are plenty of other genes at play that can affect your cancer risk. For example:
Estrogen Metabolism: Certain genes might increase the likelihood of your body producing a more reactive form of estrogen (4-Hydroxy Estrogen), which can increase cancer risk.
Glutathione Production: If your genes don’t help you produce enough glutathione (a key antioxidant), this could worsen estrogen-related issues.
Vitamin A Conversion: Some people’s genes make it harder to convert beta-carotene into Vitamin A, which is essential for immune function—especially when it comes to killing cancer cells.
Running a genetic profile can help you figure out if your body has these or other predispositions, so you can proactively support your health.

Be Proactive, Not Afraid
The key message here is to take control. Cancer doesn’t have to be a looming fear—you can make changes to lower your risk. Eat better, reduce your exposure to toxins, detox regularly (I recommend at least twice a year). And take a look at our nutrigenomics test to see if there are things that might increase your inflammation and then we can make a plan to support those deficiencies.
And most importantly, practice gratitude. It’s not only good for your soul—it’s good for your body, too. Remember: "This is the day the LORD hath made; I will rejoice and be glad in it!"
