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

Guruji Sunil Chaudhary

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.

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

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

💡 Tip: Early detection saves lives—schedule your screenings!
