Hello ..my mum has recurrent SCC and had full dose RT 3 years ago, this is a new location (1.1cm) floor of mouth ..the RO said was scared that it would cause osteonecrosis ..but this would be a new area in her mouth .. they said they didn't do cyberknife to the oral cavity, but I've read some studies that have done cyberknife on recurrent SCC on mandibular Gingival with very good results

Thanks
