Last week I had a breast sonogram done, and the results showed benign nodules, eight altogether. I've now been told to have a mammogram. I am a healthy year-old woman. Is it uncommon to have that many benign nodules in the breast, and could having my period during the test have made a difference?

Purpose: To determine whether sonography could help accurately distinguish benign solid breast nodules from indeterminate or malignant nodules and whether this distinction could be definite enough to obviate biopsy. Materials and methods: Seven hundred fifty sonographically solid breast nodules were prospectively classified as benign, indeterminate, or malignant. Benign nodules had no malignant characteristics and had either intense homogeneous hyperechogenicity or a thin echogenic pseudocapsule with an ellipsoid shape or fewer than four gentle lobulations. Sonographic classifications were compared with biopsy results.
