Usually the body maintains the system of checks and balances on cell growth, so that cells divide to produce new cells are needed. Disruption of the balance system of uncontrolled cell growth and eventually form a mass called a tumor.

Tumors can be benign or malignant, and malignant tumor is called cancer. Benign tumors can usually be removed and not spread to other body parts. But malignant tumors grow aggressively and attacking other body tissues, so that the tumor cells into the bloodstream or lymphatic system and then to the inside of the body. Distribution process is called metastasis.

Because the lung cancer tends to spread or metastasize, it is life-threatening to someone who is suffering. Lung cancer can spread to every organ in the body, especially the adrenal glands, liver, brain, and bone. This cancer is also one of the most difficult cancers to be treated. The lungs are also the organ most frequently affected by tumors in other body parts.

The reason

Decisions about treatment will be eligible for certain individuals must take into account the localization and extent of the tumor and the patient's overall health status.

Such as other cancers, maybe determined revocation or cancer therapy or palliative measures cannot cure cancer, but can reduce the pain and suffering from the patients.
