overview about some diseases
Cancer (Brain cancer)
Brain cancer is an overgrowth of cells in your brain that forms masses called tumors. Cancerous, or malignant, brain tumors tend to grow very quickly. They disrupt the way your body works, and this can be life-threatening. However, brain cancer is quite uncommon.

Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat..

Breast cancer
Breast cancer is a type of cancer that starts in the breast. Cancer starts when cells begin to grow out of control.Cancer causes the cells to multiply uncontrollably. They do not die at the usual point in their life cycle. This excessive cell growth causes cancer because the tumor uses nutrients and energy and deprives the cells around it.
