5. Lung cancer Types of Lung Cancer
There are two main types of lung cancer, distinguished by the appearance of the cancer cells under a microscope. Small-cell lung cancer is the more aggressive of the two, meaning it can spread quickly to other parts of the body early in the disease. It is strongly tied to cigarette use and rarely seen in nonsmokers. Non-small-cell lung cancer grows more slowly and is more common, accounting for almost 90% of all lung cancers.

Fatigue, wt. loss, coughing blood, night sweats
There are now strains of TB that are
Multi-drug resistant
