I Know Its A Long Shot To Give A Straight

I know its a long shot to give a straight answer. My sister is 48 doesn't take any hormone replacements is in menopause has history of cyst preent when she gets her mamograms they are not serious, this one is its cancer we don't know what type yet or what stage it's size of a orange doctor told her. I'm worried for her just wondering how serious could this be? She's tired, and it's painful. She's scheduled to see onogolisist in Chapel hill soon, I would think it should be tomorrow. Isn't time important with this...
