The objective of the study is to further understanding of proteins that occur in both normal cells and tumor cells and to learn more about certain diseases and potential alternative treatments for these diseases.
Cases will be identified from clinic patient medical records and linked to pathology reports. The surgical pathology record number will thus be obtained and used to retrieve the archival blocks and slides. Approximately three representative blocks will be selected and 4-6 four micron thick sections will be cut on a microtome. Cases with limited archived diagnostic material will not be selected nor blocks where there is little materials.
Choosing to participate in a study is an important personal decision. Talk with your doctor and family members or friends about deciding to join a study.

Accepts Healthy Volunteers:
Cases will be identified from clinic patient medical records and linked to pathology reports. The surgical pathology record number will thus be obtained and used to retrieve the archival blocks and slides. In addition, all these participants will be clinical patients of the Protocol Director, thus the Physician will always be familiar with the participants.
Patient must be over the age of 18.
Patients must have benign and malignant breast and thyroid cancer.
