Nasal cavity and paranasal sinus cancer refers to cancers that start inside the nose (nasal cavity) or in the air-filled spaces around the nose (paranasal sinuses: maxillary, ethmoid, frontal, and sphenoid). These areas sit close to critical structures such as the eyes, optic nerves, skull base, and brain, so precise, multidisciplinary care is essential. Although these cancers are uncommon, many are curable—especially when detected early and treated by a coordinated team using modern imaging, surgery, advanced radiation, and tailored systemic therapy.
