I have a question about metastisis. My sister had tonsillar cancer in right tonsil a year ago and after neck dissection pathology report said it was in one lymph node also. Is this considered a metastisis? I thought it was, but the an article in our newspaper about cancer says it is when the cancer travels from primary source toa DISTANT area of body. The example they gave was ovarian cancer traveling to brain. Would my sister's-tonsil to lymph node in neck be a metastisis?
