  • Stage I: Cancer is present, but is small and has not spread beyond the lungs

Prevention, Screening, and Diagnosis of Lung Cancer

Prevention Icon

The best way to prevent lung cancer is to avoid smoking and exposure to secondhand smoke. If you are a smoker, quitting is the most effective way to lower your risk of lung cancer.

Screening tests, such as low-dose CT scans, may be recommended for certain individuals at high risk of lung cancer. If lung cancer is suspected, your doctor may order further tests, such as a biopsy, to confirm the diagnosis.

Treatment Options for Lung Cancer

The treatment plan for lung cancer will depend on the stage of the cancer, as well as the patient’s overall health and personal preferences. Treatment options may include:

Surgery: This may include a lobectomy, which removes a portion of the lung, or a pneumonectomy, which removes the entire lung.

Chemotherapy: This treatment uses drugs to kill cancer cells.
Radiation therapy: This treatment uses high-energy beams, such as X-rays, to kill cancer cells.
Immunotherapy: This treatment helps the immune system fight cancer cells.
Targeted therapy: This treatment targets specific proteins or genes that play a role in the growth and spread of cancer cells.
If you have been diagnosed with lung cancer, it’s important to work with your medical team to determine the best treatment plan for you. With the right treatment and support, it is possible to manage lung cancer and improve your quality of life.

Tales from

Our Healthcaring Journey

Lung cancer is the leading cause of cancer deaths worldwide. People who smoke have the greatest risk of lung cancer, though lung cancer can also occur in people who have never smoked. The risk of lung cancer increases with the length of time and number of cigarettes you’ve smoked.

Dr Apar Jindal, Clinical Director & Consultant- Institute of Heart & Lung & Transplant Mechanical Circulatory, Pulmonology discusses about the causes of lung cancer and the treatment available at MGM Healthcare.

Lung Cancer

Lung cancer screening is a process that’s used to detect the presence of lung cancer in otherwise healthy people with a high risk of lung cancer. The goal of lung cancer screening is to detect lung cancer at a very early stage — when it’s more likely to be cured. By the time lung cancer signs and symptoms develop, the cancer is usually too advanced for curative treatment. Studies show lung cancer screening reduces the risk of dying of lung cancer.

Dr Balaji Ramani, Senior Consultant, Oncology, MGM Cancer Institute, Chennai has talked how lung cancer is the leading cause of deaths in India & how the early diagnosis can be helpful in saving lives.

Lung Cancer

Lung cancer surgery is an option for some patients depending on the type, location and stage of their lung cancer and other medical conditions. Removing the tumour with lung cancer surgery is considered the best option when the cancer is localized and unlikely to have spread. This includes early-stage non-small cell lung cancers and carcinoid tumours.

Dr Dhanasekar Padmanabhan, Senior Consultant, Oncology, MGM Cancer Institute, Chennai has talked about the role of surgery in treating lung cancer & saving lives.

Lung Cancer

Women are more likely than men to develop lung cancers that are unrelated to smoking. Everyone shares the same risk factors for developing lung cancer, regardless of sex. This is especially true of chronic exposure to tobacco smoke, which is responsible for 85 to 90 percent of lung cancer diagnoses overall.

Dr Shubham Sharma, Consultant, Interventional Pulmonology discusses about lung cancer is affecting the female population & what can be done about it.

Lung Cancer

Smoking is by far the leading risk factor for lung cancer. About 80% of lung cancer deaths are thought to result from smoking. The risk of lung cancer for people who smoke is many times higher than for people who don’t smoke. The longer you smoke and the more packs a day you smoke, the greater your risk.

Dr. Soumitra Sinha Roy, Senior Consultant, Pulmonology discusses about the perils of smoking & its contribution in lung cancer.

Dr Soumitra Sinha | Medical Oncology

Lung cancer is one of the commonest cancers and cause of cancer related deaths all over the world. Cancer can grow in your body for a long time — years — before you know it’s there. Lung cancer often doesn’t cause symptoms in early stages. While there are many factors that can increase your risk of lung cancer, smoking any kind of tobacco products, including cigarettes, cigars or pipes is the biggest single risk factor. The treatment will depend on the type of lung cancer you have, where it is, how far it’s spread and many other factors.
