Abstract: “Skin Ulcers are likely to be caused by the increase in UV radiation which occurs as a result of ozone depletion with the culture of the sun. Major other causes of skin cancer are burns, scars, sores, radiation or certain chemicals like arsenic. Moreover, tattooing is considered as a fashion in the younger generations, unaware of the fact that it can cause a skin cancer. However, if detected early, all forms of skin cancers are curable. This relies heavily on classifying skin lesion at an early stage. Skin lesion classification involves data from patient concerning both, their individual features and wound origin to be collected. Skin ulcer images and medical diagnosis about its grade can be stored, thereby submitting these data to the data mining procedures in order to detect some relations between them.Detection of Stage I skin ulcers become more difficult by unaided visual inspection. Therefore, patients are more prone towards developing Stage –II and Stage –III skin ulcers. Research”
