Worldwide, lung cancer remains the leading cause of cancer incidence and mortality, with 2.1 million new lung cancer cases and 1.8 million deaths predicted in 2018, representing close to 1 in 5 (18.4%) cancer deaths. In India, lung cancer constitutes 6.9 percent of all new cancer cases and 9.3 percent of all cancer-related deaths in both sexes.

Medical and Hemato- Oncologist, Dr. Harshvardhan Atreya, Apollomedics, Lucknow, told that in India squamous cell carcinoma has become the commonest lung cancer. Increasing age is the most important risk factor for most cancers. Other risk factors for lung cancer include tobacco use; Exposure to cancer-causing substances in secondhand smoke; Radiation exposure from Radiation therapy to the breast or chest; Radon exposure in the home or workplace; Medical imaging tests, such as computed tomography (CT) scans; Atomic bomb radiation; Living in an area with air pollution, Family history of lung cancer, Human immunodeficiency virus infection.

Dr. Harshvardhan Atreya also told that Lung cancer typically doesn't cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer may include, a new cough that doesn't go away, Changes in a chronic cough or "smoker's cough", Coughing up blood, even a small amount, Shortness of breath, Chest pain, Wheezing, Hoarseness, Losing weight without trying, Bone pain, Headache.


Treatment options and recommendations depend on several factors, including the type and stage of cancer, possible side effects, and the patient’s preferences and overall health. This can be done through surgery to completely remove the lung tumor and the nearby lymph nodes in the chest, “Adjuvant therapy”- treatment that is given after surgery to lower the risk of the lung cancer returning including radiation therapy, chemotherapy, targeted therapy, or immunotherapy, Radiation therapy, Chemotherapy, Targeted therapy, Immunotherapy, also called biologic therapy.


Speaking up about preventive measures, Dr. Harshvardhan Atreya said that Different factors cause different types of cancer. Researchers continue to look into what factors cause this type of cancer. Although there is no proven way to completely prevent this disease, one may be able to lower one’s risk. Based on solid evidence, long-term sustained smoking cessation results in decreased incidence of lung cancer and of second primary lung tumors. People who never smoke have the lowest risk of lung cancer. People who smoke can reduce their risk of lung cancer by stopping smoking, but their risk of lung cancer will still be higher than people who never smoked.

Based on solid evidence, exposure to secondhand smoke is an established cause of lung cancer. Research suggests that eating a low-fat, high-fiber diet, including at least five portions a day of fresh fruit and vegetables and plenty of whole grains, can reduce your risk of lung cancer, as well as other types of cancer and heart disease. Attempts to prevent lung cancer with vitamins or other treatments have not worked. There's strong evidence to suggest that regular exercise can lower the risk of developing lung cancer and other types of cancer. Adults should do at least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity each week. If you work in a job that is frequently around harmful carcinogens, such as at a construction site or in a nuclear plant, it is important to protect yourself against those carcinogens. Most employers will insist that you wear a mask or use a respirator.

Based on solid evidence, indoor exposure to radon increases lung cancer incidence and mortality, particularly among cigarette smokers. In homes with high radon concentrations, taking steps to prevent radon from entering homes by sealing the basement would be expected to result in a corresponding decrease in the risk of lung cancer.
