Is it "actually carcinogenic" or only if you use it 8 hours a day?
FWIW I run the printer in a downstairs bathroom with its own extractor fan and cure in the sun.

It's actually carcinogenic. Also, exposure can cause an allergy to resin (which makes you allergic to all sorts of everyday objects), and a single drop in your eye can cause permanent blindness.
Resin is fairly inert once fully cured + aged/dried 2 weeks, but in its uncured state PPE should always be used. The uncured resin contact with skin is known to sometimes cause autoimmune sensitivities like allergic reactions. If you ever get blisters or a rash, than you are likely no longer able to work around acrylic resins and paints.
Always protect your skin, eyes, and lungs... even when the SDS/MSDS doesn't explicitly warn of currently known possible exposure hazards.
In general, treat it the same as paint with a booth/tent, exhaust fan, and paper-lined drip pan for when(not if) the membrane perforates. If the object is small, one could also use 100% infill so it may be cleaned properly (coating prints in a automotive UV-resistant clear acrylic spray paint a few weeks later prevents yellowing, and reduces handling risks.)
Around 40% of people will get cancer in their lifetimes, and most will never know. In general, avoiding physical contact with organic solvents is a good idea, and be pleasantly surprised if it turns out to be an overly cautious decision. =3
