Inclusion Criteria:

- All patients diagnosed with breast cancer during the study period commencing January
2006, regardless of gender, ethnicity/race, stage of disease or treatment, are
eligible.

- Potential study participants must meet the eligibility criteria found in the
Eligibility Checklist. The Eligibility Checklist must be completed and stored on
site. Eligibility is confirmed during registration by answering, "yes" to the
question, "Have all eligibility criteria been met?" on the Registration Form.

- For the current proposal, we intend to include only breast cancer patients. However,
the investigators hope to eventually include the following groups: 1) Participants at
intermediate to high risk for breast cancer (documented BRCA or other genetic
syndromes for breast cancer, atypical hyperplasia or LCIS, modified Gail score
>1.66), and 2) Healthy volunteers (no history of cancer). When the infrastructure and
funding is set-up to include these participants, an amended protocol will be
submitted for HRRC review.

Exclusion Criteria:

- Not specified.
