Non-small cell lung cancer occurs when abnormal cells form and multiply in the lungs. NSCLC makes up about 80 – 85% of all lung cancer cases. NSCLC may not cause any symptoms and usually gets diagnosed after the cancer has spread. It can spread to other parts of the body like adrenal glands, bones, brain, liver, skin, and more.

• Adenocarcinoma: This type of NSCLC starts in the outer portion of the lungs and is considered the most common type.
• Squamous Cell Carcinoma: Squamous cell carcinoma usually starts from the central part of the lungs near the bronchi. This type of NSCLC is associated with smoking. 
• Large Cell Carcinoma: This type of non-small cell lung cancer can develop in any part of the lungs. 

• Surgery: Surgery may be the first line treatment and involves the surgical removal of the tumour and surrounding tissues. 
• Chemotherapy: Chemotherapy involves using drugs to kill cancer cells. Chemotherapy can also be combined with surgery and other treatment options.
• Radiation Therapy: Radiation therapy involves using X-rays to kill cancer cells. Radiation can also be used in combination with other surgical procedures. 
• Targeted Therapy: Targeted therapy for the treatment of NSCLC involves using certain types of drugs to specifically target and kill cancer cells. 
• Immunotherapy: Treatment procedure involves using drugs and medicines to boost the immune system, so it can recognize and kill cancer cells. 

Surgery: Costs approximately ₹3,00,000 to ₹8,00,000

Chemotherapy: Priced around ₹1,00,000 to ₹3,00,000 per cycle (multiple cycles may be needed)

Radiation Therapy: Priced between ₹1,50,000 to ₹5,00,000 depending on number of sessions and technology used

Targeted Therapy: Ranges from ₹2,00,000 to ₹10,00,000+ annually, depending on drugs prescribed

Immunotherapy: Typically costs ₹5,00,000 to ₹20,00,000+ per year, depending on treatment duration and drug choice

Note: The above costs are approximate and can vary based on factors such as the severity of the allergy, the specific treatment plan, the healthcare facility, and geographic location.

• Metastatic Spread: An untreated NSCLC can spread to other parts and organs of the body, like bones, liver, glands, brain, lymph nodes, etc.
• Haemoptysis: The condition can cause invasion of pulmonary vessels, causing life-threatening bleeding into the airways.
• Recurrent Chest Infections: Untreated condition can lead to the blocking of bronchi, resulting in infection and lung abscess formation.
• Respiratory Issues: An untreated condition can further spread and cause difficulty breathing, wheezing, and coughing.
• Superior Vena Cava Syndrome: SVA syndrome can result from an untreated condition causing obstruction of blood flow, leading to swelling in the face, neck, etc.
