August 18, 2021 – Mayo Clinic (Rochester, MN) announced a 110,000-square-foot, $200 million expansion to the Mayo Clinic Proton Beam Therapy Program in Rochester.
The expanded facility is expected to open in 2025. It will feature two new treatment rooms, in addition to four treatment rooms currently in operation and improved access for patients requiring proton therapy.
Mayo Clinic’s Proton Beam Therapy Program uses pencil beam scanning, which allows health care providers to deliver precise radiotherapy to cancerous tissue and lower doses of radiation to healthy tissue, subsequently reducing toxicity and negative side effects for patients receiving treatment.
The expansion will be located on the east side of the Eisenberg Building and attached to the Jacobson Building. The expansion will include two floors below ground, a lobby level and a first level, and be constructed to allow for future expansion.
Site preparation is anticipated to begin in November, with projects to include the relocation of utility tunnels and pedestrian subways. Building construction is scheduled to begin in late 2022, with a goal to begin treating patients in late 2025.
Existing proton beam therapy services will continue to be available during construction.
Once open, the expanded facility is anticipated to treat 900 additional patients per year and create 117 new jobs in a variety of roles.
Plans are also underway for Mayo Clinic in Jacksonville to add a facility where proton beam therapy and carbon ion therapy will be delivered to patients. Proton beam therapy will be available beginning in early 2026. Mayo Clinic in Florida will be the first carbon-ion treatment facility in North America, and it will open in 2027.
