Cancer cells are the bodies normal cells that for some reason (various..genetics, viruses) have become misprogramed to reproduce at a faster rate. The problem when a tumor forms is that is usually is a very vascular structure meaning it forms blood vessels inside it. It begins to rob the body of nutrients in order to feed itself which is why cancer victims loose weight.
Different cells form different tumors..hence the difficulty in fighting cancer.

They replicate non stop and at a faster rate then normal cells. This is the basis of chemo, to kill any cells that is fast replicating. There are also other normally fast growing cells in the body and are killed too - giving some side effects of chemo.
Well back to cancer cells - they would eat away any organ along their path. Also The content of the cancer cells differs also - they have mutation of their nuclear material

Cancer cells are genetically defective. Normal cells die off and are replaced in a normal cell cycle, where as cancer cells are immortal and do not die. They keep replicating forming the tumorous mass of cells. Check out Dr Burzynski's non-toxic alternative. It actually normalizes the cells on a genetic level, without harming healthy tissue.

normal cells have a regulated growth. Something tells them wehn to and not to grow. Cancer cells don't have the regulation. Thye end up taking over the nutrition that your normal cells need.

cancer cells do not have start/stop codeons. they do not know when to stop growing, which is why they are so dangerous. they continue growing killing off healthy cells that get in the way.

Cancer cells are not good for you.

cancer cells keep reducing non-stop...normal healthy cells reproduce then rest and start reproducing again...they stop after the reproduce

Usually larger than normal with a dense, abnormal chromatin pattern in the nuclei and many mitoses due to rapid growth.

Most simply (which is the limit of my knowledge) they reproduce but dont' do any good. Like, in your liver, they take up space, but dont' do any liver functions. So they don't hurt you, exactly, they just block areas where needed tissue would otherwise form.
