I think you'll find for a large majority of us, there was no lump, both times for me in 2011 and 2015 I had no lumps, all picked up in mammos and ultrasounds. So I wouldnt say it was the most common thing that people start with a lump. I personally haven't heard of BC presenting the way they are suggesting for you. It is so very hard also when other Specialists speculate. Have the tests done, if there is anything wrong, it will be in the report but again, the best person only to talk to after that would be a referral to a Breast Surgeon. Only this specialist is able to tell you exactly what it is. So it is hard absolutely, but they could be way off base, so hang in there! xx
