IDENTIFICATION OF SUSPICIOUS REGIONS TO DETECT ORAL CANCERS AT AN EARLIER STAGE– A LITERATURE SURVEY

Oral cancer is a significant health problem throughout the world. Most oral cancers are identified at a later stage where, treatment becomes less successful. It is very important to detect such types of cancer at an earlier stage. Early detection helps surgeons to provide necessary therapeutic measures which also benefit the patients. Dental Radiographs are the X – rays that help to identify problems with teeth, mouth and jaw. In this paper, a detailed survey has been done on various methods analyzed by the researchers for the detection of oral cancers at an earlier stage. A comparison is made between various methods for the identification and classification of cancers. An overview of algorithms in each step of the cancer detection algorithms is given.
