It can be used as an easy PR move to shine a spotlight on some group specific issues, like prostate cancer or breast cancer or etc.

Yes. Two things might be conflated: innate attribute (ie, biological gender) and awareness (ie, type of cancer). A mother's day#, aunt's day, or a men's day seems to subtly poke at how a group is taken for granted; that doesn't mean they need a day or special help.

I get every PR means can help as part of a holistic strategy for awareness.
