Danger: Eye damage if it hits you directly in the eye. Temporary if it’s only a short exposure, permanent if you let it keep burning a hole in your retina.
Cancer danger: None
Yes, if it’s burning a disk rather than just reading, the light is more intense, but that still doesn’t change things much. Not enough to hurt anything except the eyes, though it will damage them quicker. And since you say your eyes are fine (which they would be unless the beams were going directly into your eyes all that time, which you would have noticed), you’re totally safe.

Nothing like cancer…wrong type of radiation, but exposure could cause eye damage but nothing really severe
dont worry you hypochondriac

No you’re fine. Unless maybe you held it directly to your brain…you might lose a few cells.
Consumer electronics products go through rigorous testing before they are release. The warnings on the sides are mandatory for the manufacturer. Of course they’ll have the warnings on them because somewhere, some idiot will eventually manage to injure themselves.

A Class 3B laser produces light of an intensity such that the MPE for eye exposure may be exceeded and direct viewing of the beam is potentially serious. Diffuse radiation (i.e., that which is scattered from a diffusing surface) should not be hazardous. CW emission from such lasers at wavelengths above 315nm must not exceed 0.5 watts
