mammogram results

I feel a lump in my right breast, the doctor send me to have a biopsy but when I went in they did an ultrasound  and did not find a mass they just found an area of high density, they then proceeded to do a mammogram where they see an area that appeared white on the mammogram like a concentration of tissue and the radiologist said it is an area where there is a concentration of mammary glands and that I should not worry about it , should I ask for a surgeons opinion( my age is 25)

Dear sfinkelberg, It is difficult to comment on your results specifically without ability to review the films etc.  Getting a second opinion is always an option for you, a breast specialist - surgeon would be appropriate.
