Cancer risk is influenced more by lifestyle choices than genetics, according to Dr. Rohit Kumar C, a Consultant in Surgical Oncology at Aster Whitefield Hospital. Daily decisions regarding diet and physical activity play a pivotal role in how the body combats inflammation, builds immunity, and repairs cellular damage. Genetic mutations occur naturally during cell division, but chronic inflammation, obesity, and oxidative stress can lead to dangerous accumulations of these mutations. A diet rich in fruits, vegetables, whole grains, and legumes provides essential antioxidants that protect against DNA damage, while excessive consumption of ultra-processed foods and alcohol increases cancer risk. Regular exercise not only helps maintain a healthy weight but also boosts immune surveillance, reducing the likelihood of abnormal cell growth. The combination of a balanced diet and physical activity enhances the body’s ability to resist chronic inflammation and supports natural repair mechanisms. While no single diet or exercise regimen can guarantee cancer prevention, consistent, small lifestyle changes can significantly lower risk over time.
