9 Proven Ways to Reduce or Prevent Cancer – A Survivor’s Guide

Cancer is a word no one wants to hear, but it’s a reality that affects millions worldwide. The good news? You have the power to take control of your health and significantly reduce your risk. As a two-time cancer survivor, I know firsthand how important prevention is. My journey started during medical school, where I battled cancer and underwent radiation therapy. Seventeen years later, while working at the Mayo Clinic, I faced lung metastases. This time, I had a family—a wife and three children, the youngest just two years old. That was my turning point. I made a vow to do everything possible to never have cancer again.

So, what can you do to lower your risk? Here are nine science-backed ways to help prevent cancer and lead a healthier life.

1. Nutrition – Eat Smart, Stay Healthy 🥗

The food you eat plays a significant role in cancer prevention. A plant-based diet rich in fruits, vegetables, and legumes can reduce your risk. Here’s how to make smarter food choices:

What to Eat More of:

✅ Organic Fruits & Vegetables – Avoid harmful pesticides, especially in strawberries, peaches, and grapes
✅ Cruciferous Vegetables – Broccoli, cauliflower, and Brussels sprouts have cancer-fighting compounds
✅ Whole Grains – Brown rice, quinoa, and oats contain fiber that helps prevent colorectal cancer
✅ Legumes & Nuts – Lentils, beans, and walnuts provide essential antioxidants
✅ Healthy Fats – Include olive oil, avocados, and fatty fish for inflammation control

What to Avoid:

❌ Processed Meats – Bacon, sausages, and hot dogs increase colorectal cancer risk
❌ Excessive Red Meat – High consumption is linked to increased cancer risk
❌ High-Sugar Diets – Excess sugar promotes inflammation and weight gain, increasing cancer risk

2. Exercise – Move Your Way to Health 🏃‍♂️

Physical activity reduces the risk of many cancers, including breast, colon, and endometrial cancers. But there’s one exception—skin cancer (from excessive sun exposure).

How Much Exercise Do You Need?

✔ 150 minutes of moderate activity per week (brisk walking, swimming, cycling)
✔ 75 minutes of vigorous activity per week (running, high-intensity workouts)
✔ Strength training twice a week

💡 Pro Tip: If exercising outdoors, always wear sunblock to prevent skin cancer.

3. Avoid Smoking & Tobacco – Quit Now! 🚭

Tobacco use is the leading cause of cancer deaths worldwide. Smoking is linked to cancers of the lungs, throat, pancreas, bladder, kidney, and more.

✅ Benefits of Quitting:

• Lowers lung cancer risk by 50% after 10 years
• Improves lung function and blood circulation
• Reduces the risk of second-hand smoke exposure for family members

💡 Tip: Struggling to quit? Try nicotine patches, counseling, and support groups.

4. Alcohol Moderation – Less is More 🍷

Drinking more than one alcoholic drink per day significantly increases the risk of mouth, throat, liver, breast, and colon cancers.

Safe Drinking Limits:

✔ Men: Max 2 drinks per day
✔ Women: Max 1 drink per day
✔ Best Option? Limit alcohol or avoid it altogether

💡 Pro Tip: Opt for mocktails, herbal teas, or infused water instead.

5. Maintain a Healthy Weight – Obesity & Cancer Connection ⚖

Obesity increases the risk of several cancers, including breast, colorectal, pancreatic, and kidney cancer. Excess body fat causes chronic inflammation, which can trigger cancer growth.

How to Maintain a Healthy Weight:

✔ Follow a balanced diet
✔ Exercise regularly
✔ Reduce sugar and processed foods
✔ Get enough sleep to control hunger hormones

💡 Tip: Monitor your BMI (Body Mass Index) and waist circumference.

6. Get Vaccinated – Protect Yourself 💉

Certain viruses can cause cancer. Vaccines reduce infection risk and protect you.

Essential Vaccinations:

✔ HPV Vaccine – Prevents cervical, throat, and anal cancers
✔ Hepatitis B Vaccine – Protects against liver cancer
✔ Flu & Pneumonia Vaccines – Strengthen your immune system

💡 Tip: Talk to your doctor about recommended vaccines for your age.

7. Practice Safe Behaviors – Reduce Risky Activities ⚠

Unprotected sex and sharing needles increase the risk of viruses that cause cancer.

Healthy Habits:

✔ Use Protection – Prevent HPV & HIV transmission
✔ Avoid Sharing Needles – Reduces hepatitis & HIV risk
✔ Regular STD Testing – Early detection of infections

💡 Tip: Stay informed and practice safe behaviors.

8. Prioritize Sleep – The Power of Melatonin 😴

Quality sleep boosts immunity and reduces cancer risk.

How Sleep Helps:

• Melatonin production during deep sleep fights cancer cells
• Restores immune system to detect & destroy abnormal cells
• Reduces stress hormones, which can promote cancer growth

Better Sleep Habits:

✔ Stick to a Schedule – Go to bed and wake up at the same time
✔ Limit Screen Time – Reduce blue light exposure before bed
✔ Avoid Caffeine & Heavy Meals – Especially before bedtime

💡 Tip: Aim for 7-8 hours of quality sleep each night.

9. Regular Checkups & Early Detection – Stay One Step Ahead 🏥

Regular screenings can catch cancer early, when it’s easiest to treat.

Recommended Cancer Screenings:

✔ Skin Checks – Dermatologist exams for moles & unusual skin changes
✔ Breast Exams & Mammograms – Women over 40
✔ Colonoscopy – Adults 50+ or earlier if at high risk
✔ Pap Smear & HPV Tests – Women for cervical cancer
✔ Prostate Exams – Men 45+
✔ Testicular Self-Exams – Young men 20-30s
