Oral Cancer: Awareness, Early Detection, and Prevention of a Silent Disease
Oral cancer refers to a group of malignant conditions affecting the tissues of the oral cavity and oropharynx. These cancers can develop in areas such as the lips, tongue, cheeks, floor of the mouth, gums, palate, tonsils, and throat, often progressing unnoticed until advanced stages.
Epidemiology and Impact
Oral cancer ranks among the most common cancers globally and remains a significant public health concern. Its high mortality rate is largely due to delayed diagnosis.
However, early detection dramatically improves outcomes, with survival rates exceeding 80% in early stages, compared to significantly lower rates in advanced disease.
