Malignant melanoma is a common skin cancer that is mostly curable before metastasis, where melanoma growths spawn in organs away from the original site. Melanoma is the most dangerous type of skin cancer if left untreated due to the high chance of metastasis. This paper presents Melatect, a machine learning model that identifies potential malignant melanoma. A recursive computer image analysis algorithm was used to create a machine learning model which is capable of detecting likely melanoma. The comparison is performed using 20,000 raw images of benign and malignant lesions from the International Skin Imaging Collaboration (ISIC) archive that were augmented to 60,000 images. Tests of the algorithm using subsets of the ISIC images suggest it accurately classifies lesions as malignant or benign over 95% of the time with no apparent bias or overfitting. The Melatect iOS app was later created (unpublished), in which the machine learning model was embedded. With the app, users have the ability to take pictures of skin lesions (moles) using the app, which are then processed through the machine learning model, and users are notified whether their lesion could be abnormal or not. Melatect provides a convenient way to get free advice on lesions and track these lesions over time.
