Nasopharyngeal cancer is a form of cancer in which malignant cells form in the nasopharynx tissues. Risk factors include being of Chinese or Asian ancestry and exposure to the Epstein-Barr virus. Symptoms and signs of nasopharyngeal cancer include a sore throat, a lump in the neck or nose, trouble hearing, nosebleeds, headaches, and trouble hearing, breathing, or speaking. Treatment depends upon the stage of the cancer, the tumor size, the type of cancer, and the patient's health and age.
Most sore throats are caused by viruses or mechanical causes (such as mouth breathing) and can be treated successfully at home. However, a person should be seen by a health care professional if they have a sore throat that has a rapid onset, and is associated with a fever or tenderness of the front of the neck; a sore throat that causes the person to have difficulty swallowing (not just pain swallowing) or breathing; or if a sore throat lasts for more than a week.
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
Nosebleed is common in dry climates during winter months, and in hot dry climates with low humidity. Individual taking blood clotting medications, aspirin, or antiinflammatory medications may be more prone to nose bleeding. Other factors that contribute to nosebleed are trauma (including nose picking), rhinitis, and high blood pressure. Treatment depends on the severity of the condition.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Head and neck cancer is cancer of the oral cavity, salivary glands, paranasal sinuses and nasal cavity, pharynx, larynx, or lymph nodes in the upper part of the neck. These cancers account for 3% to 5% of cancers in the U.S. Tobacco and alcohol use are important risk factors. Treatment may involve surgery, radiation therapy, and/or chemotherapy.
Though it's difficult to say why some people develop cancer while others don't, research shows that certain risk factors increase a person's odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
