What is the origin of lung cancer?

Lung cancers typically start in the cells lining the bronchi and parts of the lung such as the bronchioles or alveoli. A thin lining layer called the pleura surrounds the lungs. The pleura protects your lungs and helps them slide back and forth against the chest wall as they expand and contract during breathing.

What cells are involved in lung cancer?

Squamous cell carcinoma: A form of non-small cell lung cancer usually found in the center of the lung next to an air tube (bronchus). Large cell carcinoma: A form of non-small cell lung cancer that can occur in any part of the lung and tends to grow and spread faster than adenocarcinoma or squamous cell carcinoma.

Which tissue is lung cancer most likely to arise from?

Lung carcinomas derive from transformed, malignant cells that originate as epithelial cells, or from tissues composed of epithelial cells.

The five-year survival rate for lung cancer is 56 percent for cases detected when the disease is still localized (within the lungs).

How long does it take for lung cancer to develop to stage 4?

It takes about three to six months for most lung cancers to double their size. Therefore, it could take several years for a typical lung cancer to reach a size at which it could be diagnosed on a chest X-ray.

What cells are found in lungs?

The lungs contain many different types of cells. Most cells in the lung are epithelial cells. Epithelial cells line the airways and make mucus, which lubricates and protects the lung. The lung also contains nerve cells, hormone-producing cells, blood cells, and structural or supporting cells.

Can you have lung cancer for years and not know it?

Early lung cancer does not alert obvious physical changes. Moreover, patients can live with lung cancer for many years before they show any signs or symptoms. For example, it takes around eight years for a type of lung cancer known as squamous cell carcinoma to reach a size of 30 mm when it is most commonly diagnosed.
