How Can Cancer Be Prevented?
Whenever I hear the word “cancer,” one question immediately comes to my mind: Can it be prevented? While there is no guaranteed way to prevent every type of cancer, medical research has shown that many cancers are linked to lifestyle, environmental exposures, infections, and certain risk factors that I can influence.
The encouraging news is that I have more control over my health than I might think. Small, consistent choices—such as avoiding tobacco, maintaining a healthy lifestyle, getting vaccinated, and attending regular cancer screenings—can significantly reduce my risk of developing several types of cancer.
At Under Nivedita’s Care, I believe that prevention is just as important as treatment. By understanding how cancer develops and taking proactive steps today, I can help protect my future health and inspire those around me to do the same.
Let’s explore the most effective, evidence-based ways I can reduce my risk of cancer.

Can Cancer Always Be Prevented?
The simple answer is no.
Some cancers occur because of inherited genetic mutations or factors beyond my control. Age, family history, and certain medical conditions can increase my risk despite living a healthy lifestyle.
However, according to global health experts, a significant proportion of cancers are preventable through healthier living and risk reduction.
Instead of worrying about what I cannot control, I choose to focus on what I can.

1. Avoid Tobacco in Every Form
If there is one lifestyle change that has the greatest impact on cancer prevention, it is avoiding tobacco.
Smoking and tobacco use increase the risk of several cancers, including:
– Lung cancer
– Oral cancer
– Throat cancer
– Esophageal cancer
– Bladder cancer
– Kidney cancer
– Pancreatic cancer
This also includes:
– Cigarettes
– Bidis
– Cigars
– Smokeless tobacco
– Gutkha
– Khaini
– Pan masala with tobacco
Even exposure to second-hand smoke can increase cancer risk.
Quitting tobacco is beneficial at any age, and the health benefits begin almost immediately.

2. Eat a Balanced, Nutritious Diet
No single food can prevent cancer, but my overall eating pattern plays an important role in reducing risk.
I aim to include:
– Plenty of fresh fruits
– Colourful vegetables
– Whole grains
– Pulses and legumes
– Healthy fats
– Nuts and seeds
I also try to limit:
– Processed meats
– Excessive red meat
– Sugary beverages
– Highly processed foods
– Excess salt
A balanced diet supports a healthy immune system and helps maintain a healthy body weight.

3. Maintain a Healthy Weight
Being overweight or obese increases the risk of several cancers, including:
– Breast cancer (after menopause)
– Colorectal cancer
– Endometrial cancer
– Kidney cancer
– Liver cancer
– Pancreatic cancer
I focus on gradual, sustainable lifestyle changes instead of crash diets.
Healthy weight management combines nutritious eating with regular physical activity.

4. Stay Physically Active
Exercise offers benefits far beyond fitness.
Regular physical activity helps:
– Maintain healthy weight
– Improve immunity
– Reduce inflammation
– Improve hormone balance
– Lower cancer risk
I aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous activity each week, along with strength training on two or more days.
Simple activities such as brisk walking, cycling, swimming, dancing, or yoga can make a meaningful difference.

5. Limit Alcohol Consumption
Alcohol increases the risk of several cancers, including:
– Breast cancer
– Liver cancer
– Colorectal cancer
– Mouth cancer
– Throat cancer
– Esophageal cancer
The less alcohol I drink, the lower my cancer risk.
If I choose to drink, moderation is important, and avoiding alcohol altogether offers the greatest protection.

6. Protect My Skin from the Sun
Excessive exposure to ultraviolet (UV) radiation is one of the leading causes of skin cancer.
To protect my skin, I:
– Apply sunscreen regularly.
– Wear protective clothing.
– Use hats and sunglasses outdoors.
– Avoid prolonged sun exposure during peak hours.
– Avoid tanning beds.
Protecting my skin today reduces the risk of future skin damage and skin cancer.
—
7. Get Vaccinated
Certain infections increase the risk of cancer.
Vaccinations can help prevent some of these cancers.
Important vaccines include:
HPV Vaccine
Helps reduce the risk of:
– Cervical cancer
– Anal cancer
– Penile cancer
– Vulvar cancer
– Certain head and neck cancers
Hepatitis B Vaccine
Reduces the risk of chronic liver infection and liver cancer.
Vaccination is a simple yet powerful cancer prevention strategy.

8. Attend Regular Cancer Screening
Some cancers can be detected before symptoms appear.
Screening helps identify disease at an earlier, more treatable stage.
Depending on my age, sex, and risk factors, my healthcare provider may recommend:
– Mammography for breast cancer
– Pap smear and HPV testing for cervical cancer
– Colonoscopy or stool-based screening for colorectal cancer
– Oral cancer examination
– Low-dose CT scan for eligible individuals at high risk of lung cancer
Screening saves lives because it allows treatment to begin early.
—
9. Know My Family History
Some cancers have a hereditary component.
If several close relatives have had cancer—especially at a young age—I should discuss this with my doctor.
Knowing my family history may help determine whether:
– Genetic counselling is appropriate
– Genetic testing is recommended
– Earlier or more frequent screening is needed
Awareness allows me to take proactive steps.
—
10. Listen to My Body
Cancer sometimes gives subtle warning signs long before it becomes advanced.
I should never ignore symptoms such as:
– Persistent lumps
– Unexplained weight loss
– Blood in stool or urine
– Persistent cough
– Difficulty swallowing
– Abnormal bleeding
– Changes in moles
– Persistent fatigue
Most of these symptoms are not caused by cancer, but they deserve medical evaluation if they persist.
—
Can Stress Cause Cancer?
This is a common question.
Current scientific evidence does not show that stress directly causes cancer.
However, chronic stress may contribute to unhealthy habits such as smoking, excessive alcohol consumption, poor diet, or lack of exercise—all of which can increase cancer risk.
Taking care of my mental well-being is an important part of overall health.

Small Habits That Protect My Health
Cancer prevention doesn’t require perfection.
Small daily habits add up over time.
I can:
– Choose stairs instead of elevators.
– Eat one extra serving of vegetables.
– Quit smoking.
– Schedule overdue health check-ups.
– Wear sunscreen.
– Stay physically active.
– Prioritize adequate sleep.
Every healthy decision is an investment in my future.

Prevention Begins Today
I cannot eliminate every cancer risk, but I can greatly influence many of them through informed choices.
By avoiding tobacco, maintaining a healthy lifestyle, staying active, limiting alcohol, protecting my skin, receiving recommended vaccinations, and attending regular screenings, I give myself the best possible opportunity to reduce my risk.
Cancer prevention is not about living in fear—it is about living with awareness.

Conclusion
Preventing cancer is not about making one perfect decision; it is about making many small, consistent choices that support long-term health. While no lifestyle can guarantee complete protection, healthy habits, regular screening, and timely medical advice can significantly reduce the risk of many cancers and improve overall well-being.
At Under Nivedita’s Care, we believe that prevention is one of the most powerful forms of care. Every positive step I take today has the potential to protect my health tomorrow and encourage those I love to do the same.
If one healthy habit could lower my cancer risk, which one will I choose to start today?
