Breast Care

The ACMH Regional Breast Care Center treats men and women of all ages presenting with a family history of breast cancer. Benign and malignant diseases are treated and surgical treatment is offered when appropriate. Located in the Cancer Center adjacent to ACMH Hospital, the office facilitates breast cancer treatment through the services of medical and radiation oncology.

High-Risk Breast Evaluation

The High-Risk Breast Evaluation, available at the ACMH Regional Breast Care Center is designed to help patients better understand their breast cancer risk by completing an individualized risk assessment and developing an individualized breast screening and risk reduction plan such as chemo prevention or risk reducing surgeries.

Patients who may benefit from a High-Risk Breast evaluation include those with a family history of breast cancer, a family member with positive genetic testing results for a known hereditary cancer syndrome, a personal or family history of ovarian cancer, dense breast tissue or concerns about breast cancer risk.
