Cancer What Lung Cancer - Non-Small Cell ? Are You Know !

Non-small cell lung cancer (NSCLC) is a type of lung cancer that accounts for about 85% of all lung cancer cases. It is a malignant tumor that begins in the cells lining the lungs and can grow and spread to other parts of the body if not treated early.

There are three main subtypes of NSCLC:

Adenocarcinoma: This is the most common subtype of NSCLC and it usually develops in the outer areas of the lung. It is more common in women and non-smokers.

Squamous cell carcinoma: This type of NSCLC develops in the lining of the bronchial tubes, which are the tubes that carry air into the lungs. It is more common in men and smokers.

Large cell carcinoma: This subtype of NSCLC is less common than adenocarcinoma and squamous cell carcinoma. It can develop in any part of the lung and tends to grow and spread more quickly than the other subtypes.

Symptoms of NSCLC can include persistent coughing, chest pain, shortness of breath, hoarseness, weight loss, and coughing up blood. Treatment options for NSCLC depend on the stage of the cancer and may include surgery, radiation therapy, chemotherapy, targeted therapy, or immunotherapy. Early detection and treatment can improve outcomes and survival rates.

Lung Cancer - Non-Small Cell why 

Non-small cell lung cancer (NSCLC) is a type of lung cancer that arises from the cells that make up the tissues of the lung. NSCLC is the most common type of lung cancer, accounting for approximately 85% of all cases.

The term "non-small cell" refers to the fact that the cancer cells are larger in size compared to the cells found in small cell lung cancer. NSCLC is further classified into three subtypes based on the type of cells that are affected:

Adenocarcinoma: This subtype of NSCLC arises from the cells that line the air sacs in the lungs. Adenocarcinoma is the most common subtype of NSCLC, accounting for about 40% of cases.

Squamous cell carcinoma: This subtype of NSCLC arises from the flat cells that line the air passages of the lungs. Squamous cell carcinoma accounts for about 25% to 30% of NSCLC cases.

Large cell carcinoma: This subtype of NSCLC is less common and accounts for about 10% to 15% of cases. It arises from the cells that make up the lung tissue, but it does not have the specific features of adenocarcinoma or squamous cell carcinoma.

The reason why NSCLC is called "non-small cell" is because the cells in NSCLC are larger than the cells in small cell lung cancer. In contrast to NSCLC, small cell lung cancer has small cells that are tightly packed together and can grow and spread rapidly.
