What is lung cancer Biology?

Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue.

How does lung cancer work biology?

Lung cancers develop through a multistep process involving development of multiple genetic and epigenetic alterations, particularly activation of growth promoting pathways and inhibition of tumour suppressor pathways.

What causes lung cancer biology?

About 90% of lung cancer cases are caused by smoking and the use of tobacco products. However, other factors such as radon gas, asbestos, air pollution exposures, and chronic infections can contribute to lung carcinogenesis.

How is lung cancer cause on a molecular level?

In order to make an impact on lung cancer, we must understand the molecular abnormalities to target better therapeutics. Lung cancers exhibit multiple genetic lesions including mutations activating the dominant cellular proto-oncogenes as well as those inactivating the tumor suppressor genes.

Is Stage 1 lung cancer curable?

With early intervention, stage I lung cancer can be highly curable. Usually, your doctor will want to remove the cancer with surgery. You also may need chemo or radiation therapy if traces of cancer remain or are likely to stay.

What are the 4 types of lung cancer?

Lung Cancer Types

  • The most common types of lung cancer include lung nodules, non-small cell lung cancer, small cell lung cancer and mesothelioma.
  • Rare lung cancers often don’t originate in the lung.
  • Rare lung cancers vary according to size, recommended treatment options and rate of metastasis.

How do u get lung cancer?

Smoking tobacco is by far the leading cause of lung cancer. About 80% of lung cancer deaths are caused by smoking, and many others are caused by exposure to secondhand smoke. Smoking is clearly the strongest risk factor for lung cancer, but it often interacts with other factors.

What is the leading cause for lung cancer?

Cigarette smoking is the number one risk factor for lung cancer. In the United States, cigarette smoking is linked to about 80% to 90% of lung cancer deaths. Using other tobacco products such as cigars or pipes also increases the risk for lung cancer. Tobacco smoke is a toxic mix of more than 7,000 chemicals.

How long can you live with lung cancer?

This means that about 1 out of 5 people with lung cancer will live for 5 years or longer after diagnosis. The outlook improves when a doctor diagnoses and treats lung cancer early. The NCI add that over half of people who receive a diagnosis of localized lung cancer will live for 5 years or longer following diagnosis.
