A survey on skin cancer detection using skin temperature variation analysis

All over the world, in recent years people were suffering from various types of cancer, the skin cancer becomes emerging in that. In India about 2 in 10 cases people are suffering from Melanoma type of skin cancer. In recent years there is no cancer screening tool available for early diagnosis of skin cancer. The existing method, skin cancer can be detected by the doctors (or) self-examination by the person (or) through certain technique which can capture only images (or) through invasive method like biopsy in the abnormal cell proliferated region. Proposed system is implementation of infrared thermal sensor in a noncontact manner which detects the temperature of the epidermal layer of skin, where the temperature of the skin varies for the subjects if they are suffering from cancer

Skin cancer detection using non-invasive techniques

Skin cancer is the most common form of cancer and is globally rising. Historically, the diagnosis of skin cancers has depended on various conventional techniques which are of an invasive manner. A variety of commercial diagnostic tools and auxiliary techniques are available to detect skin cancer. This article explains in detail the principles and approaches involved for non-invasive skin cancer diagnostic methods such as photography, dermoscopy, sonography, confocal microscopy, Raman spectroscopy, fluorescence spectroscopy, terahertz spectroscopy, optical coherence tomography, the multispectral imaging technique, thermography, electrical bio-impedance, tape stripping and computer-aided analysis. The characteristics of an ideal screening test are outlined, and the authors pose several points for clinicians and scientists to consider in the evaluation of current and future studies of skin cancer detection and diagnosis. This comprehensive review critically analyses the literature associated with the field and summarises the recent updates along with their merits and demerits
