The rise in cancer cases feels like a dread across the globe. India alone bears millions of diagnoses every year, across every age group and community. Doctors now speak with a new clarity that says many cancers are not inevitable. In fact, research shows that lifestyle choices, diet, exercise, avoiding tobacco and alcohol, are not just good for general health but have been linked to significant reductions in cancer risk, especially for breast, colorectal and prostate cancers.

Studies reveal that adopting healthier behaviours correlates with tangible reductions in cancer risk. In one comprehensive review, people who followed a healthy lifestyle, maintaining healthy weight, eating nutrient-rich foods, staying active, and avoiding smoking and excessive alcohol, showed a marked decrease in overall cancer incidence. Dr Vivek Bande, Surgical Oncologist at TGH Onco-Life Cancer in Talegaon says that combining good lifestyle practices can lower both new cancer cases and cancer deaths by nearly one-third compared to unhealthy routines. Even breast cancer mortality decreased among women who joined regular screening and maintained healthful routines.

Dr Bande adds caution and empowerment. “In view of rising cancer cases, it is necessary to exercise caution for everyone. Healthy daily choices, early screening, and lifestyle awareness can lower the risk of developing cancer,” he says, his tone as steady as it is compassionate.

He reminds us that prevention is not blame — it’s power. “While not all cancers are avoidable, adopting healthier habits can greatly reduce risk and improve overall well-being.”

Dr Bande shares tips that can help protect your health

Quit smoking and tobacco use

Tobacco in any form, be it cigarettes, bidis, chewing tobacco, carries deadly chemicals that damage DNA and spark cancer growth in lungs, mouth, throat and beyond. Stopping any tobacco habit is the single most impactful change you can make.

Eat with intention and nutrition in mind

A diet rich in fruits, vegetables, whole grains and lean proteins supports immunity and lowers cancer-linked inflammation. Processed foods, sugary snacks and red meat correlate with higher risk, so swap them for colourful, whole ingredients.

Move your body; often and with joy

Physical activity isn’t just about fitness, it’s a proven defence. Regular exercise helps regulate hormones and reduces inflammation, lowering chances of breast, colon and uterine cancers. Aim for activity most days, even if it’s brisk walking with friends.

Limit or rethink alcohol intake

Alcohol is a known carcinogen linked to cancers of the liver, breast, colon and more. Even moderate drinking can elevate risk over time; the safest choice is mindful reduction or abstinence.

Prevent infection where possible

Certain viruses like HPV and hepatitis B account for thousands of cancer cases yearly. Vaccination and safe healthcare practices are key tools in prevention, especially for cervical and liver cancers.

Follow regular screening appointments

Screening detects hidden cancers early, when treatment has the best chance of success. Tests like mammograms, Pap smears, colonoscopies or prostate checks save lives long before symptoms appear.
