I am a 26yrs old, female. I found a marble size lump in my left breast. I told my doctor and she checked. She also felt the lump. She sent me for an ultrasound and a mammogram. But when i went to the hospital, i got through the ultrasound and they said all i have is a large amount of dense breast tissue and they refused to do the mammogram on me. It’s still in a lot of pain and I’m seeking a second opinion. Can someone please explain to me what my next step should be and how to ease my breast pain i have on a regular basis?
