You have a patient with a history of breast cancer that was successively treated a year ago. She comes to you with swollen sublingual lymph nodes. What do you tell her?

You inform the patient of a need to imaging and/or a biopsy on her node to check if the swelling was caused by a recurrence of her breast cancer.

The usual nodes affected by breast cancer metastasis are the axillary nodes and the supraclavicular nodes but based on a paper published by Chaturbhuj et al. on the Indian Journal of Nuclear medicine entitled "Breast Cancer Recurrence Presenting as Solitary Intraparotid Nodal Metastasis Detected by 18F-Fluorodeoxyglucose Positron Emission Tomography: A Very Unusual Occurrence" there are rare cases of metastatic involvements of salivary glands in patients who were previously treated for breast cancer.
