In Canada, an estimated 7,400 Canadians will be diagnosed with head and neck cancer annually. Head and neck lymphedema (HNL) is a significant and commonly neglected side effect, from surgery and/or radiation therapy.
HNL could manifest externally (e.g. skin, face, neck, head), internally (e.g. oral cavity, tongue, pharynx) or both.
Prevalence of HNL ranges between 12% to 90% for external HNL, and as high as 97% for internal HNL.
