I'm in my early-mid twenties. Last April I had a surgery to remove a double fibroadenoma. I hadn't been tested ever since but I am doing so in a month.
Within this year I've had a discomfort in the breast that underwent surgery. Most days it doesn't even bother me. But at times I have this stinging sensation on that spot and my nipple gets very sensitive and sore, especially if I sleep on it or if I wear any bra. I never paid attention to it thinking it should recover but more than a year later I'm kind of panicking, as I was told by my doctor that I am in higher risk of developing non-benign growths.
Of course one can not diagnose through the internet, I'm only asking for possible similar experiences
