Primary Lung Cancer – The Leading Cancer Growth In The World

There Are Several Types Of Cancer; Primary Lung Cancer Originates In The Respiration System

When the natural growth and division of lung cells in the human body is disturbed, leading to a mass of uncontrollable expansion, the formation of a tumor develops. Some tumors are benign, stable, and will not attack or invade parts of the lung or other organs. Unfortunately this is not the case for all tumors. Primary lung cancer is the result of malignant tumors developing cancerous cells at a rate faster than the body can control them. These cancerous cells will attack anything in their path, and can travel through the body to infect and prey upon nearly any tissue matter. When a cancer develops in a specific organ, it is known as “primary”; all other tumors (benign or otherwise) that develop elsewhere are called secondary.

Primary lung cancer is the leading cancerous growth in both the United States and the world, often as a result of repeatedly inhaling chemicals or carcinogens over an extensive period of time. While tobacco use is the most common cause of lung growth, it is not uncommon for it to develop in residents of large, polluted cities or workers in industrial factories and mining facilities. Inhaling harmful material, whether it is dust or metals or microscopic shards, alters the foundation of lung cells, causing them to divide in unnatural formations or at an unusually high rate. This cancer, once established, is difficult for the immune system to fight off, as the white blood cells responsible for homeostasis are often outmatched by virulent cancerous cells.

The bloodstream is the most common “pathway” for cancer to spread through a body. Primary cancers will have a foundation in one organ, but cells traveling through the blood vessels or lymph nodes can transfer into new areas with receptive host organs. As such, it is possible to have cancerous lung cells develop on your kidneys, heart, or even brain. They are treated the same way, regardless of their location. By comparison, a benign tumor will not expand to new areas of a body, although many doctors insist on removing benign tumors for safety’s sake.
