Lung Cancer

Lungs are responsible for your body’s optimal respiratory health. Lung cancers occur when cells in the lining of the bronchi, bronchioles, or alveoli grow uncontrollably. This is the second-most common cancer in men and women in the U.S. Accounting for 1 in 5 cancer-led deaths in the U.S, lung cancer statistics are alarming.

Small cell lung cancer (SCLC) and Non-small cell lung cancer (NSCLC) are the two major types of lung cancer with NSCLCs accounting for approximately 80 to 85% of all the cases. The American Cancer Society reports 2,38,340 new cases alone in 2023 with 1,27,070 deaths. Watching out for the symptoms, evaluating risk factors and opting for periodic health screenings can help you prevent and manage lung cancer optimally.

The Types of Lung Cancer

Lung cancers can be broadly classified as Non-small Cell Lung Cancers (NSCLCs) and Small Cell Lung Cancers (SCLCs). NSCLCs can be further categorized into adenocarcinomas, squamous cell carcinomas, large cell carcinomas. SCLCs can be either Small Cell Carcinomas or Oat Cell Cancers and Combined Small Cell Carcinomas.



A type of non-small cell lung cancer that originates in the mucus-producing cells in the lungs.

Squamous cell carcinomas

Squamous cell carcinomas

A type of non-small cell lung cancer that typically begins in the thin, flat cells lining the airways.

Large cell carcinomas

Large cell carcinomas

A type of non-small cell lung cancer that can appear in any part of the lung and tends to grow and spread quickly.

Small cell carcinomas

Small cell carcinomas

A type of lung cancer that grows rapidly and is more likely to spread to other parts of the body early in the course of the disease.

Combined small cell carcinomas

Combined small cell carcinomas

A type of lung cancer that has characteristics of both small cell and non-small cell lung cancer, often requiring different treatment approaches.

The Symptoms of Lung Cancer

What Causes Lung Cancer?

Inherited and acquired genetic changes, and tobacco consumptions are deemed the potent causes of lung cancers.

Risk Factors of Lung Cancer

Risk Factors of Lung Cancer

  • Tobacco consumption
  • Exposure to passive smoking
  • Exposure to radon, the naturally occurring radioactive gas
  • Exposure to asbestos and other hazardous chemicals at workplaces
  • Excess arsenic in drinking water
  • Certain dietary supplements
  • Radiation therapy
  • E-cigarettes
  • Family history

If your healthcare provider suspects you to exhibit certain lung cancer signs, you will be recommended to go for a physical examination. Imaging tests, such as CT scans, PET scans, MRI scans, and bone scans are also recommended to identify lung cancer signs. However, for arriving at a conclusive diagnosis, you might have to undergo tests, such as sputum cytology, thoracentesis, needle biopsy, bronchoscopy, etc. Molecular tests can also be leveraged to determine genetic changes. CBC tests and blood chemistry tests can also help your healthcare provider assess your signs and determine whether you are fit for surgical interventions for eliminating lung cancer.

Lung cancer can be categorized into SCLC and NSCLC and both these variants have different stages. Thus, the treatment may also vary based on the type and stage of lung cancer.

Treatment for SCLC by Stage

Stage I – At this stage, the cancer is usually restricted to the lungs and has not spread to the nearby lymph nodes. Surgical interventions are best suited for this stage and are often followed by chemotherapy and radiation therapy to address any relapse concerns.

Limited Stage – At this stage, the tumor is relatively bigger and is often difficult to remove with surgery due to its difficult placement in the lungs. Chemotherapy, radiation therapy, and concurrent chemoradiation are often leveraged to destroy cancer cells and restrict further spread.

Treatment for NSCLC by Stage

Stage 0 – At this stage, cancer is still confined to the airways’ lining. Surgical interventions, such as segmentectomy, and sleeve resection, and therapeutic measures, such as photodynamic therapy, laser therapy, brachytherapy, etc. can be leveraged to treat stage 0 NSCLC.

Stage I – Surgery, adjuvant chemotherapy, immunotherapy and radiation therapy are some of the common treatment modalities for treating stage I NSCLC.

Stage II – Sleeve resection is the most recommended surgical procedure to remove the cancer cells. At times, pneumonectomy or the complete removal of the lungs might also be necessary depending on the cancer progression. 

Stage III – Chemotherapy, radiation therapy, immunotherapy, either in a standalone or a combination manner, can be leveraged to treat advanced-stage NSCLC. 

Stage IV – For stage IVA and IVB NSCLC, targeted therapy is recommended.


The treatment modalities for SCLCs vary slightly than NSCLCs.

The recommended treatment modalities for SCLCs include:

Surgery – Some of the key surgical interventions leveraged for treating SCLCs include:

  • Pneumonectomy – The removal of the entire lung
  • Lobectomy – The removal of the entire lobe containing tumor
  • Segmentectomy – The removal of the part of the lobe with tumor
  • Sleeve resection – This surgery aims at preserving lung function

Chemotherapy – Chemotherapy for SCLCs is often administered in an intravenous manner, through central venous catheters (CVCs) and central venous access devices (CVADs). This is ideal for SCLC as the cancer has spread and can’t be treated or managed with surgery and radiation.

Radiation Therapy – This treatment modality leverages high-energy x-rays to target cancer cells. Key external beam radiation therapy types, such as 3D-CRT, IMRT, VMAT, SBRT, and stereotactic radiosurgery (SRS) are leveraged to treat SCLCs based on the stage and progression.

Lung cancer prevention measures include:

  • Avoiding tobacco consumption
  • Avoiding exposure to radioactive and cancer-causing agents
  • Opting for healthy diet and lifestyle choices

The survival rate of Lung cancer is at least 5 years after diagnosis.

Survival rates for lung cancer have shown improvement, especially for those diagnosed at an early stage. About 65 out of 100 people with stage 1 lung cancer survive for five years or more post-diagnosis. This statistic reflects progress in early detection and treatment, bringing hope and better outcomes to those fighting the disease.
