Unlikely. It's most likely a cyst. If it's painful it certainly can be drained.
Unliklely to be Canc. Cancer can occur in 28 year olds but not likely in your case as you have cysts. Most lumps(>80%) turn out to be cysts. So quit worrying...That will cause pain.

Even painful breasts can be taken care of well by a breast ex.
