I understand how ionizing radiation can damage DNA. I understand how certain reactive molecules can do the same. I understand how this damage can lease to tumorigenesis.
I do not understand how certain small particles cause cancer. Off the top of my head (and after a quick look around my lab), these substances have carcinogenic dust:
celite 454 (I’m not sure exactly what this is…DE and other stuff?)
molecular sieves (I’m not sure of the composition of this either)
Does anyone know why they are so bad to breathe?
