Lung cancer is a disease in which cancer cells grow in the lungs.
Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor.
The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.
There are two types of lung cancers:
Non-small cell lung cancer—generally grows and spreads more slowly (more common form)
Small cell lung cancer—generally grows more quickly and is more likely to spread to other parts of the body
is the use of radiation to kill cancer cells and shrink tumors. This may also be used to relieve symptoms, such as shortness of breath. Radiation may be:
External—directed at the tumor from a source outside the body (more common for treating lung cancer)
Internal—radioactive materials placed into the body in or near the cancer cells
the use of drugs to kill cancer cells. This may be given in many forms, including pill, injection, and via a catheter. Chemotherapy is often used to kill lung cancer cells that have spread to other parts of the body.
Promising New Treatments
These two types of treatments are not yet widely used. The National Cancer Institute considers these potential therapies:
Photodynamic therapy (PDT)—a type of laser therapy. A chemical is injected into the bloodstream. It is then absorbed by the cells of the body. The chemical rapidly leaves normal cells. It will remain in cancer cells for a longer time. A laser aimed at the cancer activates the chemical. This chemical then kills the cancer cells that have absorbed it. This treatment may also be used to reduce symptoms.
Cryosurgery—a treatment that freezes and destroys cancer tissue
