Brief summary
The purpose of this study is to see if Positron Emission Tomography (PET) imaging with a radioactive form of the hormone progesterone called FFNP will give the same results as hormone receptor testing already performed on tissue used to diagnose breast cancer.
Interventions
PET imaging following injection of F18-FFNP to image hormone receptor status in patients with newly diagnosed breast cancer
Blood and urine samples for standard laboratory testing and radioactive counts will be obtained during the imaging sessions. Testing will include: urinalysis, complete blood count, comprehensive metabolic panel, and progesterone levels
ECG tracings and vital signs (blood pressure, heart rate, body temperature and respiration rate) are obtained at several time points before, during and after the imaging sessions.

Eligibility
Inclusion criteria
* Female patients 18 years of age or older * Biopsy-proven breast cancer * Tumor estrogen-receptor and progesterone-receptor status already determined or scheduled to be determined at time of surgery without intervening therapy. * Primary lesion size ≥ 1.5 cm as determined by imaging studies (ultrasonography, mammography, CT or MRI) or physical examination * Able to give informed consent * Not currently pregnant or nursing: Subject must be surgically sterile (has had a documented bilateral oophorectomy and / or documented hysterectomy), post menopausal (cessation of menses for more than 1 year), non lactating, or of childbearing potential for whom a urine pregnancy test (with the test performed within the 24 hour period immediately prior to administration of FFNP) is negative.
Exclusion criteria
* No previous history of hormone therapy; NOTE - subjects who were treated with hormone therapy for reasons other than breast cancer or breast cancer prevention may be allowed to participate after review of history by the primary investigator * Patients with other invasive malignancies, with the exception of non-melanoma skin cancer, who had (or have) any evidence of the other cancer present within the last 5 years * Unable to tolerate 60-90 minutes of PET imaging per imaging session
