Skin cancer is the most common type of cancer in Brazil, representing about 33% of cases of malignant neoplasms in the country. Melanoma is a type of skin cancer that represents only 3% of cancer cases in the organ, but it is considered the most offensive due to high possibility of metastasis, which is the spread of cancer to other organs. Although melanoma is considered the main fatal skin disease, the introduction of new drugs combined with the detection of the tumor in early stages have contributed to positive prognosis. Through the ABCDEs rule of melanoma, it is possible to identify melanoma by watching some characteristics present in the lesion, however, the identification of melanoma through observation is often a failure, especially when it comes from an inexperienced doctor. Therefore, this work aims to select and use Machine Learning techniques to propose a model that can help dermatologists to identify skin lesions through dermoscopic images, serving as a second opinion to say if it is or it is not melanoma. The proposed model was compared with techniques widely used in the literature for solving complex problems, with the objective of presenting superior performance. Using Precision and Recall, the proposed model proved to be comparable to the others, although it had access to only 0,1% of the dimensions of the image, which indicates that the model worked well on finding the characteristics that discriminate skin lesions.

O estágio supervisionado obrigatório ocorreu baseado no acompanhamento das consultas, atuando no auxílio na manipulação dos animais, dentre outras atividades. Foi coletada ao total uma casuística de aproximadamente 75 felinos durante quase três meses, sendo vivenciados diversos casos, com ênfase em sistemas hepatobiliar, gastrointestinal e renal. O paciente felino por ser mais predisposto a desordem à nível de oxidação dos ácidos graxos pelos hepatócitos, ou da própria incapacidade do fígado para segregar as lipoproteínas encarregadas de transportar as triglicérides através da corrente sanguínea justificam a alta demanda apresentada pelos pacientes no período do estágio. Assim como, por questões próprias da espécie, e questões de manejo, a predisposição de alterações a nível de sistema renal e gastroentérico.

Skin cancer is the most common type of cancer worldwide, divided into two main types: melanoma and non-melanoma. Although rarer, melanoma is the most lethal due to its potential to cause metastasis. Non-invasive methods, such as dermoscopy and the ABCDE rule, have been used to avoid unnecessary surgical procedures and have helped in the identification of lesions, contributing to faster diagnoses. With advances in technology, Artificial Intelligence (AI) has gained prominence, proving to be a promising solution for medical data analysis, especially with the use of Convolutional Neural Networks (CNNs), which can recognize patterns in dermoscopic images and help classify lesions as melanoma or non-melanoma in an automated manner. This project proposes an ensemble of classifiers based on Convolutional Neural Networks to classify dermoscopic images as melanoma or non-melanoma, comparing its performance with validated architectures, such as AlexNet and VGG-16, using Transfer Learning techniques The analyses of Precision, Recall, and F1 Score showed that the ensemble of Convolutional Neural Networks outperformed the models using Transfer Learning techniques, with AlexNet showing better performance than VGG-16. The ensemble of Convolutional Neural Networks demonstrated a greater generalization capability, proving to be promising in capturing relevant features from the images, revealing potential for medical applications, although it still needs refinement to meet clinical standards.
