Lung cancer is basically what happens when the cells in lung tissue begin growing at a rate that the body cannot cope with - the lungs are some of the most vital organs and the need a delicate balance of homeostasis like the rest of the body. Lung cancer can lead to potentially metastasis, an invasion of nearby bodily tissue and posibly the lung cancer can spread into other parts of the body.
Lung Cancer Information

Lung cancer is one of the most common causes of death in men and second most in women (women die mostly from breast cancer).

Lung Cancer Symptoms Defined
Some of the more common symptoms of lung cancers are a constant cough, a sudden change in coughing habits, or being short of breath. This is due to the alveoli being constricted from cancerous grouwth. Also, other symptoms of lung cancer can be a persistent coughing up of phlegm or blood, as well as problems or pain when breathing.
The cancerous cells in the lungs cause an imbalance in the body's nutrition and possibly nerve impulses, which can lead to a loss of appetite and weight from not eating properly. Fatigue will also occur.
Other lung cancer symptoms, less common until the cancer becomes advances, can be a hoarse voice, difficulty swallowing, a swelling in the face, which would be caused by a blocked blood vessel. If the lung cancer has reached the liver, it's likely that there'll be pain and discomfort in the right side of the body beneath the ribs. The lungs will have fluid built up around them, which will cause a shortness of breath due to the lungs themselves not being able to expand.
