Introduction

Every year, National Cancer Awareness Day, observed on November 7, reminds us that early action saves lives. Cancer remains one of India’s most serious health challenges—with over 14 lakh new cases reported annually. Yet, experts say nearly 40% of cancers are preventable through simple lifestyle changes.

To mark National Cancer Awareness Day 2025, leading oncologists share evidence-based, everyday habits that significantly reduce cancer risk. From eating right to quitting tobacco, these small but powerful choices can safeguard your health and that of your family.

Understanding Cancer and Prevention

Cancer occurs when abnormal cells grow uncontrollably, damaging tissues and organs. While genetics play a role, lifestyle and environment account for the majority of cases.

Cancer prevention means adopting healthy habits to lower your risk of developing the disease. These habits don’t just protect you from cancer—they also improve overall immunity, energy, and longevity.

7 Everyday Habits to Lower Cancer Risk — Oncologist Tips

1. Eat a Balanced, Colourful Diet

Nutrition plays a powerful role in cancer prevention.

  • Include 5+ servings of fruits and vegetables daily—they’re rich in antioxidants that protect cells.
  • Choose whole grains (brown rice, oats) over refined ones.
  • Limit red and processed meat.
  • Use healthy oils like mustard, olive, or sunflower instead of hydrogenated fats.

Oncologist Tip: “A diet rich in fiber, antioxidants, and plant-based foods reduces inflammation and cellular damage—two major cancer triggers.”

2. Stay Physically Active

Exercise helps regulate hormones and strengthens the immune system.

  • Aim for at least 150 minutes of moderate activity per week—brisk walking, yoga, or cycling.
  • Avoid prolonged sitting; take short movement breaks every hour.

Oncologist Tip: “Even 30 minutes of daily movement can lower breast, colon, and lung cancer risk significantly.”

3. Avoid Tobacco in All Forms

Tobacco is linked to over 30% of cancer deaths in India.
Whether smoked or chewed, it damages DNA and promotes uncontrolled cell growth.

  • Quit smoking and avoid secondhand smoke.
  • Avoid gutka, khaini, and betel quid, which increase oral cancer risk.
  • Seek medical help for de-addiction if needed.

Oncologist Tip: “The risk of oral and lung cancer begins to drop within months of quitting tobacco.”

4. Limit Alcohol Consumption

Alcohol acts as a carcinogen—it increases risks of liver, breast, and esophageal cancer.

  • If you drink, keep it minimal (≤1 drink/day for women, ≤2 for men).
  • Stay hydrated and prioritize alcohol-free days.

Oncologist Tip: “Cutting back on alcohol supports your liver and reduces the risk of multiple cancers.”

5. Protect Your Skin from UV Rays

Excessive sun exposure damages skin cells and may lead to skin cancer.

  • Use SPF 30+ sunscreen daily, even indoors.
  • Avoid direct sunlight between 10 AM – 4 PM.
  • Wear protective clothing and hats.

Oncologist Tip: “Melanin protects but doesn’t make Indians immune—UV rays still cause DNA damage.”

6. Go for Regular Screening and Vaccination

Early detection is key.

  • Schedule regular screenings: mammograms, Pap smears, colonoscopies.
  • Get vaccinated for HPV (cervical cancer) and Hepatitis B (liver cancer).

Oncologist Tip: “Regular screening finds precancerous changes early—before symptoms appear.”

7. Manage Stress and Sleep Well

Chronic stress weakens immunity and may indirectly raise cancer risk.

  • Practice mindfulness, yoga, or meditation.
  • Get 7–8 hours of sleep nightly.
  • Spend time with loved ones and limit screen time.

Oncologist Tip: “Sleep is your body’s natural repair time—don’t compromise on it.”

Why Cancer Prevention Matters in India

India faces unique cancer challenges—late diagnosis, lifestyle risks, and limited awareness.
Common cancers include breast, cervical, oral, and lung cancer—many of which are preventable.

Simple lifestyle steps, regular screening, and early consultation with oncologists can change outcomes dramatically.
