Synchronous cancers are multiple cancers that develop within six months of the initial diagnosis while metachronous cancers are those that develop more than six months after the initial diagnosis. A combination of three cancers is seen with several patients, which leads to a bad prognosis, and that of synchronous cancers is worse than that of metachronous cancers. Herein, we describe the case of a 62-year-old woman with multiple metachronous head and neck cancers.
Keywords: aero-digestive tract; metachronous cancers; synchronous cancers.
