How Can I Lead a Lifestyle That Keeps Cancer Away for a Long Time? Simple, Practical Lifestyle Changes to Reduce Your Cancer Risk By Dr. M. G. Giriyappagoudar Senior Radiation Oncologist | HCG Cancer Centre, Hubballi, North Karnataka
Introduction Cancer is a growing health concern, but the good news is that many cancers are linked to lifestyle choices and preventable risk factors.
Although no lifestyle can guarantee complete protection from cancer, healthy habits can significantly reduce the risk of several cancers and improve your overall health.
Here are 12 simple steps everyone can follow to reduce their cancer risk and live a healthier life.
- Say NO to Tobacco Avoid smoking cigarettes, beedis and other tobacco products.
Stay away from gutka, khaini and chewing tobacco.
Avoid areca nut (supari), which can also cause cancer.
Quit tobacco at any age to improve your health.
Avoid exposure to second-hand smoke.
Remember: Tobacco is one of the leading preventable causes of cancer.
- Eat a Healthy and Balanced Diet Eat plenty of fresh vegetables and fruits.
Include whole grains, millets, pulses and beans in your daily diet.
Choose healthy protein sources such as dal, beans and nuts.
Limit processed meat such as sausages, bacon and ham.
Reduce frequent consumption of red meat and highly processed foods.
Avoid excessive sugary drinks and calorie-rich snacks.
Do not depend on detox drinks, herbal juices or supplements to prevent cancer.
Remember: A balanced diet and healthy body weight are more important than expensive superfoods.
- Exercise Every Day Walk briskly for at least 30 minutes on most days.
Try cycling, swimming, dancing or other activities you enjoy.
Avoid sitting continuously for long hours.
Use stairs whenever practical.
Include strength-training exercises at least twice a week.
Remember: Aim for 150–300 minutes of moderate physical activity every week.
- Maintain a Healthy Body Weight Avoid excessive weight gain.
Eat balanced meals and control portion sizes.
Reduce frequent consumption of high-calorie foods.
Combine regular exercise with healthy eating.
Avoid crash diets and unproven weight-loss products.
Remember: Excess body fat is associated with an increased risk of several cancers, including breast cancer after menopause and endometrial and colorectal cancers.
- Avoid Alcohol Avoid alcohol for the lowest possible alcohol-related cancer risk.
Do not start drinking for supposed health benefits.
If you drink, consider reducing or stopping your consumption.
Remember: Alcohol increases the risk of several cancers, including cancers of the mouth, throat, food pipe, liver, breast and bowel.
- Take Recommended Vaccinations Get the hepatitis B vaccine if you are not adequately vaccinated.
Discuss HPV vaccination for eligible children, adolescents and adults.
Follow your doctor's advice regarding vaccination schedules.
Remember: HPV and hepatitis B infections are associated with certain cancers, and vaccination can help prevent these infections.
- Do Not Ignore Cancer Screening Women should follow recommended breast cancer screening guidance.
Follow recommended cervical cancer screening with HPV testing and/or other appropriate tests.
Eligible adults should discuss colorectal cancer screening with their doctor.
People who use tobacco or areca nut should seek medical assessment for suspicious oral lesions.
People with a strong family history of cancer may need earlier or additional screening.
Remember: Screening is intended to detect certain cancers early, sometimes before symptoms develop. Not everyone needs every screening test.
- Know Your Family History Find out whether close relatives have had cancer.
Pay attention to cancers occurring at unusually young ages.
Consult your doctor if several relatives have had breast, ovarian, pancreatic, prostate or colorectal cancer.
Consider genetic counselling if your family history suggests an inherited cancer risk.
Remember: A family history does not mean you will develop cancer, but it may help identify people who need additional preventive care.
- Protect Yourself From Excessive Sun Exposure Avoid prolonged exposure to strong sunlight.
Wear protective clothing and a broad-brimmed hat.
Use broad-spectrum sunscreen of SPF 30 or higher on exposed skin.
Avoid artificial tanning devices.
Consult a doctor about a changing mole or a skin sore that does not heal.
Remember: Ultraviolet radiation can damage the skin and increase the risk of skin cancer.
- Recognise the Warning Signs of Cancer Consult a doctor if you notice:
A lump in the breast or another part of the body.
A mouth ulcer that does not heal within two weeks.
Persistent difficulty swallowing or hoarseness.
Blood in the urine or stools, or coughing up blood.
Unexplained weight loss.
Persistent changes in bowel or bladder habits.
Unusual vaginal bleeding.
A persistent cough or a changing skin lesion.
Remember: These symptoms do not always indicate cancer, but persistent or unexplained symptoms should not be ignored.
- Sleep Well and Manage Stress Maintain a regular sleep schedule.
Aim for 7–9 hours of sleep each night as an adult.
Practise yoga, meditation or relaxation techniques if helpful.
Spend quality time with family and friends.
Seek professional help for persistent sleep or mental health problems.
Remember: Good sleep and stress management support overall health, although they are not proven ways to prevent cancer on their own.
- Avoid Unnecessary Tests and Unproven Treatments Do not undergo whole-body scans without an appropriate medical indication.
Avoid unnecessary radiation examinations while accepting medically indicated tests.
Do not depend on unproven cancer-prevention supplements or herbal remedies.
Choose screening tests based on your age, medical history and individual risk.
Consult a qualified doctor before starting any cancer-prevention programme.
Remember: More tests do not always mean better health care. The right test at the right time is what matters.
