NSC Lung Cancer

What Is Non-small cell lung carcinoma (NSCLC)/ Lung Cancer ?

Lung cancer starts when cells of the lung become abnormal and begin to grow out of control. As more cancer cells develop, they can form into a tumor and spread to other areas of the body, a process called metastasis.
Types of non-small cell lung cancer
There are 2 main types of lung cancer:
About 80% to 85% of lung cancers are non-small cell lung cancer (NSCLC)
About 10% to 15% are small cell lung cancer (SCLC)
There are subtypes of NSCLC, which start from different types of lung cells. But they are grouped together as NSCLC because the approach to treatment and prognosis (outlook) are often similar

Adenocarcinoma: 40% of lung cancers are adenocarcinomas. These cancers start in early versions of the cells that would normally secrete substances such as mucus
This type of lung cancer occurs mainly in current or former smokers, but it is also the most common type of lung cancer seen in non-smokers. It is more common in women than in men, and it is more likely to occur in younger people than other types of lung cancer. Adenocarcinoma is usually found in outer parts of the lung. Though it tends to grow slower than other types of lung cancer and is more likely to be found before it has spread, this varies from patient to patient.

Squamous cell (epidermoid) carcinoma: About 25% to 30% of all lung cancers are squamous cell carcinomas. These cancers start in early versions of squamous cells, which are flat cells that line the inside of the airways in the lungs. They are often linked to a history of smoking and tend to be found in the central part of the lungs, near a main airway (bronchus).

Large cell (undifferentiated) carcinoma: This type accounts for about 10% to 15% of lung cancers. It can appear in any part of the lung. It tends to grow and spread quickly, which can make it harder to treat. A subtype of large cell carcinoma, known as large cell neuroendocrine carcinoma, is a fast-growing cancer that is very similar to small cell lung cancer.

Key Facts On Lung Cancer

The five-year survival rate for lung cancer is 56 percent for cases detected when the disease is still localized (within the lungs). However, only 16 percent of lung cancer cases are diagnosed at an early stage. For distant tumors (spread to other organs) the five-year survival rate is only 5 percent
Treatments Available:-
Targeted Therapy
Lung Cancer is the largest cancer killer in the world
Lifetime lung cancer risk for men is one in 13; one in 16 for women. These numbers include smokers and nonsmokers.
