Symptoms of cancer inside the nose, also known as paranasal sinus or nasal cavity cancer, include nosebleeds, congestion, runny nose and facial numbness, explains the National Cancer Institute. Nose cancer can also lead to the formation of lumps on the roof of the mouth or inside the nose.
Tumors caused by nasal cavity cancer and paranasal sinus cancer can put pressure on the sinuses and nerves, manifesting in blocked sinuses, facial numbness and tingling, ear pressure, and eye problems, as the National Cancer Institute explains. Nasal cavity cancer is characterized by nosebleeds, congestion and nasal sores that do not heal properly.
Types of nasal cancer include sarcoma, melanoma and inverting papilloma, according to the National Cancer Institute. Inverting papilloma is when tumors grow inside the nose, but these tumors are often benign, or noncancerous. Melanoma begins in the skin cells, while sarcoma cancer starts in the muscle or connective tissue inside the nose. A midline granuloma, which is a cancer of central facial tissues, may also affect the nasal cavity. A person with nasal cavity cancer may need chemotherapy, radiation therapy or surgery. The National Cancer Institute also mentions clinical trials, which use experimental drugs and treatments that are being tested for effectiveness.
