Thyroid nodules are growths or lumps in the thyroid gland. It can be due to growth of thyroid cells or a collection of fluid. They are relatively common, but should be looked at by a physician. Only about 5% of thyroid nodules are cancerous, but those that are cancerous need to be removed.
A lump in the neck: A lump in the neck that lasts for more than two weeks should be seen by a physician as soon as possible. Not all lumps are cancer, but a lump (or lumps) can be the first sign of cancer of the mouth, throat, larynx, thyroid or certain lymphomas. Such lumps are usually painless and enlarge steadily.
Change in the voice: Any hoarseness or other voice change lasting more than two weeks should alert you to see your physician. An otolaryngologist is a head and neck physician who can examine your vocal cords easily and painlessly. Most hoarseness is not caused by cancer, but should be seen by a physician who can determine the cause.
A growth in the mouth: Most cancers of the mouth or tongue cause a sore or swelling that does not go away. These sores may be painless until they become infected. Bleeding may occur, but not until later stages of the disease. Your dentist or doctor can determine whether a biopsy is needed.
Swallowing problems: Cancer of the throat or esophagus may make swallowing difficult. If you have consistent trouble swallowing food or liquid, you should be examined by an otolaryngologist to determine the cause.
Persistent earache: Constant pain in or around the ear when you swallow can be a sign of infection or tumor growth in the throat. An ENT physician can best evaluate these symptoms.
