Know all about Lung Cancer from the experts.

 In Cancer

Lung cancer is a serious health concern around the world, particularly in cities like Delhi, India, where environmental pollution and smoking contribute to the disease’s prevalence. Dr. Ashish Gupta, a renowned oncologist at Unique Hospital Cancer Centre in Delhi, India, sheds light on this complex disease, aiming to simplify understanding and highlight the most recent advances in treatment.

Understanding Lung Cancer:

Lung cancer, which results from uncontrolled cell growth within the lungs, is India’s fourth leading cause of cancer. It is classified into two types: non-small cell lung cancer (NSCLC) and small cell lung cancer. NSCLC, the most common type, has subtypes such as adenocarcinoma and squamous cell carcinoma, whereas SCLC is known for its rapid progression.

Causes and Risk Factors:

Tobacco smoke remains the primary cause of lung cancer, contributing to around 85% of cases globally. However, non-smokers can also develop lung cancer due to exposure to factors like radon gas, asbestos, and air pollution. Dr. Ashish Gupta emphasises the significance of environmental factors, particularly in cities like Delhi, where high levels of air pollution are a major concern.

Symptoms and Diagnosis:

Early-stage lung cancer may not cause obvious symptoms, making early detection difficult. However, as the disease progresses, symptoms like a persistent cough, chest pain, and difficulty breathing may appear. Imaging tests such as X-rays and CT scans are typically used to make the diagnosis, which is then confirmed by a biopsy.

Breakthroughs in Treatment:

Recent years have seen significant advances in lung cancer treatment, including targeted therapy and immunotherapy. Dr. Ashish Gupta discusses these novel approaches, which provide more personalised treatment options based on the tumour’s specific genetic makeup.

Targeted Therapy:

Targeted therapy focuses on specific genes or proteins found in cancerous cells. For patients with specific genetic mutations, targeted drugs can effectively inhibit cancer growth and spread while minimising side effects.


Through immunotherapy, cancer cells are fought off by the body’s immune system. Immunotherapy has improved lung cancer patient survival rates by stimulating the immune system’s ability to fight cancer.


While lung cancer remains a major health concern, there is hope for better outcomes through prevention and ongoing research. Dr. Ashish Gupta emphasises the importance of quitting smoking and limiting exposure to environmental risk factors. Staying up to date on the latest advances in lung cancer research and treatment is critical for medical professionals who want to provide the best care to their patients.

In conclusion, Dr. Ashish Gupta, an experienced oncologist at Unique Hospital Cancer Centre in Delhi, India, emphasises the importance of understanding lung cancer and the most recent advances in treatment. Improved outcomes in the fight against lung cancer are possible thanks to targeted therapy, immunotherapy, and preventive measures.
