Early signs of nasal cancer mostly refer to the early symptoms of nasal cancer, which may manifest as pain, nasal congestion, bleeding and so on. Patients should do pathological examination, nasal cavity examination, tumor marker and other related examinations to clarify the cause of disease. 1. Pain: Because cancer cells press surrounding nerves, it will cause compression symptoms and patients will manifest local pain. 2. Nasal congestion: patients with early nasal cancer whose cancer cells grow in nasal cavity or sinus will have nasal congestion. 3. Bleeding: When cancer cells are stimulated adversely, it may cause bleeding in the affected area and the symptom of blood in nasal mucus may appear. Patients who have pain in the nose area, nasal congestion and bleeding should actively consult doctor, do not delay the condition, and standardize the treatment under the guidance of doctor’s consultation, and patients should not use medicine by themselves.
