Hi jane
I had an ongoing sore red hot breast just below the nipple off and on for about six years
I was told it was a blocked milk duct
In February this year I went for a checkup with my new doctor for my hypothyroidism tests and mentioned the sore breast to him
Immediately sent for mammogram, ultrasound and surgeon
The area I complained about all these years showed a 100mm mass of dcis
By May I had wide incision (1.3kg of tissue taken) and sentinel node biopsy
So no I don't think your mad I would most definitely ask for further investigation especially when you have a history
All the best
