Guide To Effective Lung Cancer Diagnosis And Treatment

Lung cancer is a type of cancer that originates in cells that form in an individual's lung tissues. Lung cancer leads the United States in most cancer precipitated fatalities, claiming more lives than prostate, ovarian, colon, and breast cancers combined. The most prevalent causes of lung cancer are cigarette smoking and prolonged secondhand smoke exposure. Individuals who do not smoke can also get lung cancer, but causes of such cases are unclear. Symptoms include shortness of breath, chest pain, headache, bone pain, hoarseness, coughing blood, and a persistent cough.
