In October I Found A Lump In My Breast. I've

In October I found a lump in my breast. I've had 2 ultrasounds and a mamogram showing nothing. Two doctors and myself have felt the lump. The surgeon did a needle biopsy and the results came back inconclusive. The pathologist is recommending an incisional biopsy and the surgeon is using the wait and see approach. I don't know if I should search a second opinion.
