[Marvel] What are some unforeseen problems with becoming a giant, Ala Giant man or Stature?

Would I be able to breathe? Where does the extra mass come from? What should I know that I probably wouldn't think to consider?

Assuming you're using Pym Particles, you have nothing to worry about.  If you're becoming giant without them, and aren't a mutant or otherwise have some superpower to help you do it... well it was nice knowing you.
