how come there isn't more
cancer awareness stuff?

I mean you can go into any
store practically and find at
least one item to buy for 
breast cancer awareness,
but why not more cancers?

I'm not saying it's bad that
there's so much stuff for
breast cancer, I'm just 
saying it's the only kind of
cancer where you can 
walk into a store and see
a display of items to buy
where some proceeds
go towards the cause.
