Tungsten-cobalt alloys extremely carcinogenic?

You don't use thoriated tungstens, do you? Ernie Leimkuhler likes lanthanated, so that's what I use. Thoriated are slightly radioactive. Cobalt and chromium compounds can be bad actors. I've never heard of tungsten itself being a problem. Nickel can cause allergies, as can damn near anything else.

Personally, I'm not at all sure I'd prefer Alzheimer's to cancer. Laying around as the living dead for 10 years doesn't appeal. My preference would be to just keel over doing something I like. One of Dad's old friends liked beer and playing cards, and during a card game about midnight, went and laid down on the couch not feeling too good and passed away. He was 92, I think. Dad's 91 and still plugging along.

That's a great way to die.

I thought Russian chemist and composer Alexander Borodin went out the right way, he dropped dead of a stroke during one of his frequent house parties.

I had a friend that did a lot of cobalt blue ceramic glasses and he died of a mysterious to the doctors cancer.

Not enough is known due to a small test base and want/need.

I wouldn't forget a cancer diagnosis.
