Your body doesn't make cancer cells you potato. It's what happens when their self destruct cycle refuses to engage. They are immortal cells that something in your environment has triggered to not die.
Yes, you can catch a virus with negative results after it abuses your body into reproducing them out of control, triggering your body to kill the manufacturing point. There are useful, and also deadly bacteria/virus combinations to us as humans.
You missed my point entirely. You can't "catch" cancer from someone. Cancer is an auto-immune response of your body.
Likewise you can't "catch" a virus. A virus is an auto-immune response of your body.
You can catch bacteria from your environment, however, you can't catch a virus because viruses don't exist outside of your body. Just like cancer. There aren't cancer cells floating in the air. Likewise there are no virus cells floating in the air.
100% troll or retarded.
Show me proof you can catch a cancer from someone?
