What is Lung Cancer?
LUNG CANCER: an uncontrolled growth of abnormal cells in lung tissue. Primary lung cancer originates in the lungs, while metastic lung cancer spreads to the lungs from another organ. Classification is based on the type of cell the cancer originates from: adenocarcinoma, alveolar cell carcinoma, squamous cell carcinoma, large cell, and small cell carcinomas.
Lung Cancer - The leading cause of cancer death in the U.S., lung cancer is broken down into two groups: small cell lung cancer and non-small cell lung cancer. Although there is no cure, preventative measures can drastically reduce a person's risk of developing lung cancer.
Lung cancer is the malignant transformation and expansion of lung tissue, and is the most lethal of all cancers worldwide, responsible for up to 3 million deaths annually. Although lung cancer was previously an illness that predominantly affected males, the incidence in women has been increasing in the last few decades, which has been attributed to the rising ratio of female to male smokers. Currently, lung cancer is the leading cause of cancer death in women, overshadowing breast cancer, ovarian cancer and uterine cancers combined.However, it is of note that there are certain types of lung cancers that appear in otherwise healthy patients who have never smoked.
