Smoking and Lung Cancer: The Connection You Need to Know




When discussing lung cancer, the Best Oncologist in Delhi, Dr. Dodul Mondal, emphasizes the undeniable link between smoking and the development of this deadly disease. Smoking remains the leading cause of lung cancer, contributing to around 85% of all cases. The harmful chemicals in tobacco smoke, such as tar, nicotine, and carbon monoxide, directly damage the cells in the lungs. Over time, these damaged cells can turn cancerous, leading to the development of tumors.

Even though the risk is significantly higher for smokers, it's important to note that non-smokers are not entirely safe from lung cancer. Secondhand smoke, also known as passive smoking, can also be a significant risk factor. Inhaling smoke from others can cause the same type of damage to lung cells as direct smoking, increasing the likelihood of lung cancer.

Quitting smoking is the most effective way to reduce the risk of lung cancer. The body begins to heal almost immediately after quitting, with lung function improving and cancer risk decreasing over time. For those who have smoked for many years, the benefits of quitting are still substantial and can lead to a significantly lower risk of developing lung cancer.

In conclusion, the connection between smoking and lung cancer is clear and well-established. Whether you are a smoker or exposed to secondhand smoke, it's crucial to understand the risks and take steps to protect your lung health. For those concerned about lung cancer or seeking advice on quitting smoking, consulting with the Best Oncologist in Delhi, Dr. Dodul Mondal, can provide expert guidance and support. Early detection and proactive measures can make a significant difference in outcomes.
