LUNg CAncer

"Every breath is a reminder of the preciousness of life, and in the face of lung cancer, we stand resolute, fueling the fight with unwavering determination and the power of knowledge. Together, we strive for a future where every breath is free from the shadow of this disease."


Lung cancer is a complex and serious disease characterized by the uncontrolled growth of abnormal cells in the lungs. It is primarily caused by tobacco smoking, including both active smoking and exposure to secondhand smoke. However, other risk factors, such as exposure to asbestos, radon gas, air pollution, and genetic predisposition, can also contribute to its development. 

Lung cancer is categorized into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most common type, accounting for about 80-85% of cases, while SCLC represents approximately 10-15% of cases. Each type has distinct characteristics, treatment options, and prognoses.

WHAT IS LUNG CANCER?

TYPES OF LUNG CANCER

Non-Small Cell Lung Cancer (NSCLC)

  • Adenocarcinoma: This is the most common subtype of NSCLC, usually found in the outer areas of the lungs. It often develops in current or former smokers and can also affect non-smokers. Adenocarcinoma can spread to other parts of the body.
  • Squamous Cell Carcinoma: This type typically occurs in the central part of the lungs and is often associated with a history of smoking. It tends to grow slowly and is less likely to spread initially compared to other types.
  • Large Cell Carcinoma: This is a less common subtype of NSCLC. It can appear in any part of the lung and tends to grow and spread rapidly. It is often diagnosed when the cancer has already advanced.

Small Cell Lung Cancer (S CLC)

  • Small Cell Carcinoma (Oat Cell Cancer): This type of lung cancer is highly aggressive and tends to grow quickly. It is strongly associated with smoking and is often diagnosed at an advanced stage. Small cell carcinoma typically starts in the central part of the lungs and has a high tendency to spread to other organs.
  • Combined Small Cell Carcinoma: This subtype involves a mixture of small cell carcinoma and non-small cell carcinoma components, such as adenocarcinoma or squamous cell carcinoma.
  • Small Cell Carcinoma with Neuroendocrine Features: This subtype exhibits neuroendocrine features, including the production of hormones or neuropeptides, such as ACTH (adrenocorticotropic hormone) or ADH (antidiuretic hormone).
  • Small Cell Carcinoma with Variant Histology: This refers to SCLC that demonstrates atypical histological patterns, such as glandular or spindle cell differentiation, which may resemble other types of cancer.
