I'm 50, not been called for breast screening yet so never had a mammogram and don't know much about how they're actually performed. I've found a lump tonight but it's on the flat, bony bit between my collar bone and where my actual breasts start (if that makes sense!) so I'm wondering whether a mammogram would even cover that area, is it even breast tissue there? Obviously I'll be ringing my GP on Monday but just wanted to get an idea what might happen next in terms of tests.
