Breast Cancer is the most fatal diseases with high mortality rates, such as this one, survival prediction assumes an important role, since it aids clinicians to better define each patient's prognosis and the corresponding treatments to be attempted. In particular for breast cancer, prognosis is related to the patterns of prediction. Cancer Prediction describes cancer that reappears after treatment, and in the specific case of breast cancer, prediction is very common, being experienced by about one third of patients after initial diagnosis. Therefore, establishing the patterns of prediction is a crucial task to accurately predict the clinical behavior of this pathology. This enables a more personalized treatment for the patients, avoiding undesired overtreatment and adverse complications. Gradient Boosting is a powerful machine learning algorithm founded on the idea that combining the labels of many 'weak' classifiers or learners translates to a strong robust one to predict the breast cancer. Boosting is a greedy algorithm that fits adaptive models by sequentially adding these base learners to weighted data where difficult to classify points are weighted more heavily. Experts claim that gradient boosting is the best off-the-shelf classifier developed so far to detect and predict the Breast Cancer. As we can see from the above versions of boosting, a unique boosting algorithm can be derived for each loss function and its performance can vary depending on which base learner. We can derive a generic version of boosting called gradient boosting for the identification, detection, recognition and prediction of breast cancer.
