Brief Summary
Our objective in this pilot study will be to identify PA parameters that can distinguish benign vs. malignant lesions, and also, if PA parameters change with within breast tumors during chemotherapy t...
Detailed Description
This study will investigate photoacoustic tissue characteristics of breast lesions both at diagnosis, and within a separate subgroup of patients, physiological changes in breast tumors during neoadjuv...
Eligibility Criteria

- Subjects must give appropriate written informed consent prior to participation in the study;
- Subjects must be able and willing to comply with the safety procedures during the Scanning Period;
- Subjects must be men and women of between 20 to 80 years of age, inclusive, on the day the Informed Consent Form is signed;
- Subjects must be receiving neoadjuvant chemotherapy for locally-advanced breast cancer.
- Biopsy-confirmed diagnosis of locally advanced breast cancer; of all molecular subtypes (ER+/-, PR+/-, HER2+/-).
Exclusion
- Subjects with a past medical history of abnormalities, significant injury, or medical or surgical procedures (e.g. Silicone/saline implants) involving either breast, exclusive of the lesion at issue;
- Subjects with any dermatologic abnormalities (including tattoos, open sores, or breached skin) involving either breast;
- Subjects with a current or past medical history of connective tissue disease;
- Subjects who are pregnant or lactating;
- Subjects with an implanted electronic device such as a cardiac pacemaker, defibrillator, or neurological stimulator;
- Subjects with a history or expectation of significant anxiety associated with undergoing diagnostic evaluations;
- Subjects with a history of musculoskeletal disease which may predispose them to discomfort during the Scanning Period;
- Subjects with a known sensitivity to low-power infrared radiation (e.g., as a result of a dermatologic condition); and
- Subjects, who, in the opinion of the investigator or clinical research coordinator, may not otherwise be appropriate for inclusion into the study.
- Cohort 2 - Breast Mass Characterization:
- Inclusion Criteria:
- Subjects must give appropriate written informed consent prior to participation in the study;
- Subjects must be able and willing to comply with the safety procedures during the Scanning Period;
- Subjects must be men and women of between 20 to 80 years of age, inclusive, on the day the Informed Consent Form is signed;
