Disorders of the throat may be caused by inflammation, infection, or growths such as polyps, ulcers or even cancerous tumors. Throat problems are very common, especially in young children. A sore throat is usually minor and may go away on its own. However, some sore throats can be caused by a streptococcus (usually called just strep) bacteria and may require an antibiotic. If you see white patches on the back of your throat, you should suspect strep throat and see your doctor. If you have a lump or sore that doesnt go away, trouble swallowing or hoarseness and especially if you smoke and drink alcohol, you may be at risk for throat or mouth cancers. If found early these kinds of cancers are often curable. See your doctor to get the right diagnosis.
