@tisme - when you advised your team of the lump, did they do a mammogram and/or ultrasound to check it out, or a biopsy? I would imagine that would be 'standard procedure' first up ..... if they didn't - maybe contact your local cancer centre or GP (or even the Cancer Council) and get that sorted first. Best to do it before the weekend - as you'll be more worried over the weekend. :(
Please ring the helpline (number is up on the blue banner at the top of the page) and have a chat with one of the mods - they will be able to talk you thru it & may be able to give you phone numbers to contact up there..
All the best xx
