It is the same question for any other kind of cancer. My question is if when you have metastasis you have differente kind of cancers or only one in different tissues. If you have different kinds of cancer, must they be treated sepately?

I always notice on the oil bottles when I change my oil about how contact of oil with the skin has been tied to some kinds of cancer, or something like that. Isn’t all the grease, brake dust (asbestos), gasoline, antifreeze, freon, and oil, hazardous? Well, I know it is. I guess it’s okay if you work on your own car from time to time and you’re careful, but what about the mechanics that work on cars ALL DAY, EVERYDAY, THEIR ENTIRE LIVES – BLACK FINGERS THEIR WHOLE LIFE. This is constant exposure. Even though they’re careful and don’t DRINK the antifreeze, they are exposed to it at some small level – for a prolonged period of time. Your skin can absorb this stuff.
