Skin Cancer Deteciton Using ABCD Rule
Human Cancer is one of the most dangerous diseases which is mainly caused by genetic instability of multiple molecular alterations. Among many forms of human cancer, skin cancer is the most common one. To identify skin cancer at an early stage we will study and analyze them through various techniques named segmentation and feature extraction. Here, we focus on malignant melanoma skin cancer, (due to the high concentration of Melanoma- Hier we offer our skin, in the dermis layer of the skin) detection. In this, we used our ABCD rule dermoscopy technology for malignant melanoma skin cancer detection. In this system different steps for melanoma skin lesion characterization i.e, first the Image Acquisition Technique, pre-processing, segmentation, definition feature for skin Feature Selection determines lesion characterization, classification methods. The Feature extraction by digital image processing method includes symmetry detection, Border Detection, color, and diameter detection, and also we used LBP to extract the texture-based features. Here we proposed the Back Propagation Neural Network to classify the benign or malignant stage.
Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body.
There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous cell skin cancer (SCC), and melanoma. The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).
Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death. It often appears as a painless raised area of skin that may be shiny with small blood vessels running over it or may present as a raised area with an ulcer.
Squamous-cell skin cancer is more likely to spread. It usually presents as a hard lump with a scaly top but may also form an ulcer. Melanomas are the most aggressive.
Signs include a mole that has changed in size, shape, color, irregular edges, has more than one color, is itchy, or bleeds. A skin that has inadequate melanin is exposed to the risk of sunburn as well as harmful ultraviolet rays from the sun . Clinical analysis and biopsy tests are commonly used.
