I know someone who was just diagnosed with Gental Warts, and he thinks he has one on his neck. Do they spead to other areas of your body like that? Can you get them on your neck, hands, arms ect? Thanks!

1.Recently I found those warts and I am extremly nervouse about it because I heared it only happens to old men/women am I in a trouble?
2.I live in Toronto. Is there any good skin care centre near me?
