Sadly, you should be suspicious because this &quot;article&quot; is just a gloss of the university&#x27;s press release (and university press releases are notoriously worthless).<p>The clue is phrases like &quot;a cure rate of 98.6 percent&quot;.  First of all in any therapy that&#x27;s an extraordinary number.  But in face what&#x27;s a &quot;cure&quot;?  Typically a study has specific endpoints; in oncology (not my specialty) they&#x27;ll be things like 5 year survival, tumor size reduction etc.<p>SBRT appears to be effective for small, contained tumors apparently like prostate cancer, so that part is great.
