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]
Head and neck cancer is a general term encompassing multiple cancers that can develop in the head and neck region. These include cancers of the mouth, tongue, gums and lips (oral cancer), voice box (), throat (nasopharyngeal, oropharyngeal, [1] hypopharyngeal), salivary glands, nose and sinuses.
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.
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 tongue cancer is a cancer that happens in the front two-thirds of the tongue, while oropharyngeal tongue cancer forms at the base of the tongue in the back portion of the mouth and can extend ...
For men over 64 with prostate cancer limited to the pelvis, using fewer, larger doses of radiation (hypofractionation) results in similar overall survival rates. [28] The risk of dying from prostate cancer or having acute bladder side effects may be similar to that of longer radiation treatment. [ 28 ]
Prognosis is good for acinic cell carcinoma of the parotid gland, with five-year survival rates approaching 90%, and 20-year survival exceeding 50%. Patients with acinic cell carcinomas with high grade transformation (sometimes also called dedifferentiation ) have significantly worse survival.
Over a 45-year span — between 1975 and 2020 — improvements in cancer screenings and prevention strategies have reduced deaths from five common cancers more than any advances in treatments.
