The lungs play a significant role in the human body. Increased air contamination and inadequate lifestyle choices affect lung well-being, which can lead to life-threatening diseases such as cancer, doctors say.
Lung cancer is now a significant health problem and accounts for around 13% of all new cancers in India. Misconceptions surrounding the disease, regardless of its high incidence, continue to prevail. Indian experts share their insights to raise awareness of the disease.

Dr Vishwanath S, medical oncologist consultant, Apollo Hospitals, Bangalore, explains: “The most standard types of lung cancer are non-small cell tumors (NSCLC) and include adenocarcinomas and squamous cell carcinomas, among others. Small cell tumors tend to be aggressive and progress rapidly, accounting for about 10-20% of all lung cancers.There is a possibility that cancers from other parts of the body will spread to the lungs, these are called metastases.
What are the symptoms?
It is difficult to detect the disease in its early stages as symptoms may be close to those of a respiratory infection or there may be no indications. Dr. Lancelot Pinto, consultant pulmonologist, PD Hinduja Hospital & MRC, mentions symptoms that may be related to less severe and acute illnesses:

Dr Sajjan Rajpurohit, Principal Consultant- Medical Oncology & Center Head, Max multi-specialty center, explains: “Normally you should be screened after age 50, but if you have smoked tobacco in the past, screen with a low dose CT. (LDCT) could be something you should discuss with your doctor. Detection of non-cancerous abnormalities is common and could lead to anxiety and invasive testing, so you should be mentally prepared and advised before undergoing such screening. “

Additionally, environmental exposure to tobacco (ETS or secondhand smoke), occupational exposure to certain chemicals, air pollution and a genetic predisposition could all contribute, “adds Dr. Lancelot Pinto, consultant pulmonologist, PD Hinduja Hospital. & MRC.
