How does cancer kill you without treatment?

There are several ways it might. First, cancer cells metabolize (i.e. eat) other cells in the body, thus causing tissue damage to whatever they happen to be growing in. Second, cancer cells physically get in the way of other cells just by being there and not doing the job they are supposed to.

Can cancer cells disappear?

The process is typically called “spontaneous regression” or “spontaneous remission,” and a considerable body of literature confirms that cancer and benign tumors do indeed “disappear” and, in exceptional cases, patients are cured of the disease — in which case the phrase “miraculous healing” is sometimes invoked.

What cancer does to body?

Cancer can press on nearby nerves and cause pain and loss of function of one part of your body. Cancer that involves the brain can cause headaches and stroke-like signs and symptoms, such as weakness on one side of your body. Unusual immune system reactions to cancer.
