Cancer of the Tongue
Tongue cancers are oral cancers that are differentiated by their location in the mouth and on the tongue. If the cancer is on the forward portion of the tongue, it is known as a squamous cell cancer of the oral tongue. If the cancer is located towards the rear third of the tongue, it is known as a squamous cell cancer at the base of the tongue. (rarediseases.org)
Generally, the first sign of squamous cell cancer of the oral tongue is a pinkish-red sore at the side of the tongue that persists and seems not to heal over time. Quite often, the sore bleeds easily if bitten or touched. If this occurs, it is recommended that the person see a physician, especially if the person is older than fifty. (rarediseases.org)
In its earliest developmental period, squamous cell cancer of the base of the tongue is asymptomatic. This means that the cancer does not make itself known until later in its growth. However, symptoms may begin with pain in the tongue and surrounding tissue, changes in voice tones and sounds, and difficulty in swallowing that may lead to feelings of bloat or fullness.
Because the early symptoms are dormant, most squamous cell cancers of the base of the tongue are further advanced by the time a patient sees a physician. Many patients will have already had squamous cancer cells in the lymph nodes of the neck (metastases). (rarediseases.org)
About 5 percent of all oral cavity tumors are verrucous carcinoma, a type of very slow-growing cancer made up of squamous cells.
Only 1 in 8 (12.5%) happen in people younger than 50.
Smokers who also drink heavily are 15 times more likely to develop oral cancers than other people.
The five-year relative survival rate for tongue cancer (which compares the survival of people with cancer with the expected survival rate for people without cancer) depends on the stage of the cancer. If the cancer has spread far, the five-year relative survival rate is 36 percent . If the cancer has only spread locally (for example, to lymph nodes in the neck), the relative survival rate is 63 percent. If the cancer has not spread beyond the tongue, the five-year relative survival rate is 78 percent. (healthline.com)
Lifetime
Risk of Developing Cancer : Approximately 0.4 percent of men and women will be diagnosed with tongue cancer at some point during their lifetime, based on 2015–2017 data. (seer.cancer.gov)
