I personally use a supplied air mask whenever I weld. Even outside. I think the fumes affect different people differently. I, myself, feel the effects even after a few minutes, and I feel the possible risk and permanent future discomfort is worth the annoying discomfort of a supplied air mask now.

I do not know the real risks. I have asked doctors and they just stare at me.

Safety is paramount in this industry. And I think the biggest concerns are those things that we cannot see. I just do not see anything, even $ justifying the risk so many welders take.
