A major interest of Frass is
homeopathy. He has published several papers on this subject.
Article in the Oncologist In 2020 Frass was the corresponding author of an article in the medical journal
The Oncologist which concluded that additional homoeopathic treatment improves
quality of life and
survival rates in patients with
non‐small cell lung cancer (NSCLC). The results of the article were discussed outside of academic circles, for example in the
Wiener Zeitung. After criticism (for example from the Informationsnetzwerk Homöopathie), the
Austrian Agency for Scientific Integrity (Österreichische Agentur für wissenschaftliche Integrität) concluded that the article contains
data manipulation and forgery.
The Oncologist released an
expression of concern in 2022 and
retracted the article in November 2025. ==Airway==
