There are two basic types of strokes: haemorrhagic (caused by bleeding) and ischemic (caused by a lack of blood supply). Both lead to abnormal brain function in certain areas.

Breast cancer.

Lung cancer, another name for respiratory cancer, is a type of cancerous growth that starts in the lungs. It happens when aberrant cells in the lung tissue proliferate out of control.


The one of the most dangerous diseases that mostly affects the lungs are called tuberculosis (TB). 

When a person with tuberculosis coughs, sneezes, or sings, the disease can spread. These TBs release minute amounts of the germs into the atmosphere. The bacteria can then enter the lungs of another individual who inhales the droplets.
