A recent interview with Dr. Neeraj Goel, director of oncology services at the CK Birla Hospital, Delhi, shed light on the link between tobacco consumption and colorectal cancer. According to Dr. Goel, tobacco smoke contains carcinogens that can damage colon cells’ DNA, leading to uncontrolled cell division and cancer. Smoking also initiates chronic inflammation, oxidative stress, and disruptions in cellular function, all of which contribute to the development and progression of colorectal cancer.
Studies have shown that smoking increases the risk of colorectal cancer by 18-30% compared to non-smokers, and this risk is higher for long-term smokers. Even after quitting, former smokers still face an increased risk for several years.
To prevent colorectal cancer, Dr. Goel recommends quitting smoking, undergoing regular screenings, adopting a healthy lifestyle, and maintaining a balanced diet. Early detection through screenings like colonoscopies can help catch the disease when treatment is most effective. It is important to seek professional medical advice for any questions or concerns about colorectal cancer and to follow prevention tips to reduce the risk of developing this type of cancer.
