What exactly is Cancer?
In: Biology
Basically, cancer happens when cells in your body lose self control. Cells have a set of instructions on how to operate contained in their DNA/genes. Sometimes old cells don’t die like they should and start growing abnormally. They can pass messages to cells around them that makes them grow abnormally also, and this mass of abnormal cells is called a tumor. If the tumor grows slowly and doesn’t spread or destroy other tissues, it’s benign and isn’t what we’d considered cancer, and is typically easily treated with targeted removal. If it grows rapidly, and invades and destroys tissues around it, it is malignant and is what we consider cancer. When it spreads to different organs it has traveled, or metastasized, and it’s very hard to treat conservatively and has a very bad prognosis (chance of recovery).
