Double meaning of the ‘Cancer’ term.

I'm más and más annoyed por the term ‘Cancer’, which refers to a zodiac sign and at the same time to the horrible disease...

Anyone knows why is it so? Why haven't anyone suggest a change?

I've heard many times: “how to defeat cancer” guide. Thank tu very much tu want to defeat myself. :/

I'm really angry with this ‘coincidence’! D:<
