Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Good question: And difficult to tell sometimes. The most straightforward way to put it is that a benign neoplasm will never turn into an invasive malignancy within your lifetime. Cis will eventually turn into one. But, because we don't live forever, cis might not turn into a malignancy during one's lifetime anyway. Pathologists can usually, but not always, tell the difference by microscopic cell exam. ...Read more
