Cancer is the second leading cause of death in the United States and affects 1 out of 3 people in the world. It is a heterogeneous class of disease that comes in many forms and invades different part of the body.

Different symptoms surface depending on the type of cancer a person develops but general symptoms include unexplained weight loss, blood when coughing, and change in bowel movements. The exact cause of the disease is unknown but some medical professional claims it comes from carcinogens.

The disease comes in two types: Type I or insulin-dependent diabetes, an autoimmune disorder that destroys the pancreas’ ability to produce insulin, and Type II or the more common form that generally affects obese people, it is caused by slow pancreatic secretion of insulin or the insufficient responsiveness or cells producing insulin. Common diabetes symptoms include frequent urination, extreme fatigue, extreme thirst, blurry vision, and bruises that heal slowly. But there are more specific symptoms for each type like losing weight for Type I and numbness of hands and feet for Type II. There’s no cure for diabetes but those who have Type II diabetes can control their blood glucose through exercise and eating right.
