Cancer is out-of-control cell division. It involves a change in the DNA structure that causes an alteration of the normal DNA regulating mechanisms. The malignant (cancerous) cells no longer respond to normal regulatory signals. Cancer most often strikes older individuals.

How do cancers spread?
When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.
