Changes in skin, such as a small pale or reddened area on the skin surface, persistent ulcer, persistent changed skin lesion, or a sore throat which does not heal may also indicate skin cancer. Basal cell cancers are commonly seen cancers which are easily treated. They occur due to sun exposure and are prevalent on the face or forehead. A sore on the lip, face, forehead or ear that does not heal needs medical attention. A black or blue-black spot or a mole that undergoes color changes, bleeding, or change in size needs to be immediately examined by a physician.
Malignant melanoma can present with the above symptoms and can be a serious problem.
Lastly, a constant earache or ear pain when you swallow can indicate infection or a throat tumor. Examination by an otolaryngologist is recommended. In summary, any of the aforementioned symptoms, a lump in the neck, changes in your voice, a growth in the mouth, blood tinged secretions, problems with swallowing, changes in skin, or persistent earache may be symptoms of head and neck cancer. However, if the symptoms lead to the diagnosis of cancer, there is hope that if caught early, this disease is very treatable and potentially curable. These chronic irritants are responsible for mouth, throat, voice box and tongue cancers.
