How often should I check my breasts?

You should check your breasts every month beginning at about age 20. At this early age, any small lumps are probably just normal breast glands and ducts. Over time you will get used to how your breasts normally feel so that you're able to tell if a new lump appears. Check your breasts a few days after your period (when your breasts are usually less sore). If you don't have periods or if they come at varying times, check your breasts at the same time every month.
