All cancer patients are discussed at conferences attended by these cancer specialists. There are multiple cancer specialists involved simultaneously and from the beginning. This is why cancer center accreditation is so critical. This level of team involvement is what is required. Dr. Mangiameli’s program is the only accredited cancer center from Patchogue to Montauk and Orient. He has offices in Patchogue, Southampton, and Riverhead. Every site visit of Dr. Mangiameli’s team since 2014 by the American College of Surgeons has resulted in a perfect full accreditation.

This includes minimally invasive breast surgery, complex oncoplastic surgery, chest wall resections and reconstruction, nipple-sparing and traditional mastectomies, sentinel lymph node mapping and biopsy, and full lymph node dissections. Additionally, he collaborates with his plastic surgery colleagues to achieve immediate reconstruction using implants and all forms of autologous flap reconstruction. In addition, he has extensive training and experience in screening and managing women who have high breast cancer risk from genetic mutations and other cumulative risk factors.
He has been a founding program director of a breast cancer center here in Suffolk County since 2014. Dr. Mangiameli has continuously provided the energy and leadership to compel and coordinate these clinical teams. Together they have treated thousands of women according to national guidelines. Additionally, he has been involved in many community outreach programs, including the NYS Cancer Screening Program. He also serves as a Police Surgeon for The New York State Troopers and the Police Surgeons Benevolent Association.
