I’m only 19 years old, and I’ve noticed a lump in by right breat. I’ve had it for about a month, my mom .. who’s a nurse told me to watch it and just wait, but it showed up before my period and i’m about to start again. It hurts really bad, like it burns sometimes. My family doesn’t have a history of breast cancer or anything and when my mom and aunt were younger they both got cysts, do you think thats what this is?
