What is Lung Cancer?

Home Abstract What are Lungs? Small-cell Cancer Non-small-cell Cancer Risk Factors Glossary At a Glance Bibliography/Acknowledgement

The Human body is made up of millions of cells. These cells normally divide and multiply in an orderly fashion. New cells replace older cells and shape our growth patterns by applying the specific genes and living habits of the body. Cell Birth and Renewal is what this process is called and it occurs constantly in each and every living body.

When an action of uncontrolled growth of abnormal cells occur, the population of cells become overflowing, and instead of creating thin, uniformly arranged cells they create lumps in the tissue and form a tumor.

The tumor could be benign (quiet, not bothersome) or malignant (troublesome). The malignant tumor is called Cancer.

In a benign tumor the cells do not spread to other parts of the body and they are not cancerous. In a malignant tumor cancerous cell could spread into the other parts of the body and spread the disease.
