Is Breast Massage Necessary to Find Sentinel Lymph Node?

Sentinel lymph node biopsy is important for staging in patients with breast cancer and changes the way of surgery. One of the most commonly used methods to find the sentinel lymph node during surgery is to apply blue dye around the areola and then search for the sentinel lymph node. Breast massage is recommended following administration of the blue dye. However, the necessity of this massage is controversial. In this study, investigators will try to find out whether massage of the breast after blue dye injection has any positive effect on finding the sentinel lymph node.
