  • Anastrazole
    Newly diagnosed, non-metastatic, hormone-receptor positive breast cancer patients, who have undergone lumpectomy, have been advised to not require chemotherapy, but will need to undergo radiation therapy and will be initiating therapy with anastrazole.
  • Control group - 2

Inclusion Criteria:

  • Ambulatory women (aged 60-75), with a new diagnosis of nonmetastatic, hormone-receptor positive breast cancer, having undergone lumpectomy. They will not need chemotherapy and will have been prescribed but not yet started anastrazole. All will need a course of radiation therapy as part of usual care. Participants are instructed not to change their physical activity or eating habits over the period of the study.

Comparisons are:

  • Identical to the cases except they are hormone-receptor negative and don't need hormonal therapy.
  • Healthy controls.

Exclusion Criteria:

  • Nicotine usage
  • Metastatic breast cancer
  • Need for chemotherapy
  • AI other than anastrazole
  • Usage of steroids (equivalent of equal then or more than 7.5 mg prednisone x 3 months)
  • Clinically significant abnormality of thyroid function
  • Treatment with gonadal hormone replacement therapy within last 3 years
  • Status post unilateral/bilateral surgical oophorectomy
  • Having experienced a medical event, which may confound study outcomes [e.g. heart attack, stroke, cancer (metastatic or newly diagnosed within last 5 years, except for non-melanoma skin cancer and breast), lupus, rheumatoid arthritis, chronic inflammatory disease]
  • Medication-dependent diabetes mellitus or hypercholesterolemia.
  • Gastric surgery
  • Weight loss medication (prescription or over the counter)
