TY - JOUR T1 - PRemenarchal breast nodules AU - Allaben RD Y1 - 1979/08/17 N1 - 10.1001/jama.1979.03300070016015 JO - JAMA SP - 618 EP - 618 VL - 242 IS - 7 N2 - To the Editor.—  In addition to the proper answers to the question regarding a breast nodule in a premenarchal girl (241:1621, 1979), I believe there is another cause of unilateral breast nodules. This is local self-trauma. It usually occurs in the breast opposite the child's handedness and often is seen when the child has a sibling or good friend who is beginning to experience normal breast development. The treatment is reassurance of the child as well as the parents. SN - 0098-7484 M3 - doi: 10.1001/jama.1979.03300070016015 UR - http://dx.doi.org/10.1001/jama.1979.03300070016015 ER -
