Head and Neck Cancers Cancer
The oral cavity, pharynx, larynx, nasal cavity, para nasal sinuses, salivary glands, and thyroid. In Tanzania there is no national prevalence data about head and neck cancers but data available at ORCI shows that they contribute about 7% of all cancers.
These tumours may present with a neck mass due to lymph node metastases, with or without findings from the primary disease site. Important etiological factors are smoking, excessive alcohol, viral infections (eg HPV and EBV), genetic predisposition, previous exposure to radiation and industrial chemicals. Squamous cell carcinoma is the commonest histological type for the malignancies but salivary gland tumors are mostly adenocarcinoma
