I've found lumps before and they turned out to be non cancerous cysts. But yeah, scary as hell!! Don't know about you but the time after finding the lump and getting the relieving words from the doctor I was a basket case. It's all I could think about and played out a zillion scenarios in my head including the funeral! My mind just ran with it. I think that's not unusual though. It's a scary thing. Good that you got a doctor's appointment, being proactive is smart.

Work on distractions to help you through this period. The games section here is awesome for chilling out. Keep posting and take good care.
