Oral cancer has an overall 5 year survival rate of 65% in the United States as of 2015. [4] This varies from 84% if diagnosed when localized, compared to 66% if it has spread to the lymph nodes in the neck, and 39% if it has spread to distant parts of the body. [4] Survival rates also are dependent on the location of the disease in the mouth. [16]
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.
HPV-positive oropharyngeal cancer generally has a better outcome than HPV-negative disease, with a 54% better survival rate, [18] but this advantage for HPV-associated cancer applies only to oropharyngeal cancers. [19] People with oropharyngeal carcinomas are at high risk of developing a second primary head and neck cancer. [20]
The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer. The 5-year relative survival rate drops to 22% for women with stage IV breast cancer. [3]
Oral cancer is a malignant abnormal excessive growth of cells within the oral cavity, which arises from premalignant lesions through a multistep carcinogenesis process. [12] Most oral cancers involve the lips, lateral border of the tongue, floor of the mouth, and the area behind the third molars, i.e. the retromolar area. [13]

“In 2023, 15-to-44-year-old Californians (to whom we refer as “young adults” in this report) died at a rate of 128 per 100,000 people, compared to just 99 per 100,000 in 2019—
Natal and neonatal teeth are an anomaly that involves teeth erupting in a newborn infant's mouth earlier than usual. The incidence ranges from 1:2,000 to 1:3,500 births. Natal teeth are more frequent, approximately three times more common than neonatal teeth. Some authors reported a higher prevalence in females than males.
