Perseon Corporation (PRSN) develops, manufactures, markets and services medical systems that treat cancer using heat therapies, including hyperthermia systems for oncology applications such as the Sigma family of hyperthermia systems and the MicroThermX microwave generators; it offers electro-medical and electrotherapeutic apparatus focused on non-invasive cancer treatment solutions. The company, formerly known as BSD Medical Corporation, was incorporated in Delaware in 1986, changed its name to Perseon Corporation around 2016, and maintains headquarters in Salt Lake City, Utah, with operations primarily in the United States targeting healthcare providers and oncology centers worldwide. In recent developments, Perseon has continued to emphasize its legacy hyperthermia technology platform amid a dormant profile in public markets, with no major funding rounds, acquisitions, partnerships or new product launches reported in the last 1-2 years as of late 2025.
