This work is about breast cancer which is one of the main causes of mortality in women.
Early detection remains very crucial to improve survival among breast cancer patients. In this
project two main topics are investigated. The first one is related to the automatic detection of
breast cancer using complete blood count (CBC). The second one deals with the prediction of
survival among breast cancer patients. Both detection and prediction go through two stages,
namely feature selection and classification. Different techniques are used for feature
selection. These techniques belong to either the filter approach or the wrapper approach. In
the classification stage, number of machine learning algorithms are used to classify the data
in to two classes, namely cancer and cancer-free for detection version and survive and die for
survival prediction version. Last stage is to evaluate the evaluation metrics like: accuracy,
sensitivity, specificity and area under the curve (AUC). In the breast cancer detection CBC
results at first entry to the clinic give better evaluation metric with 78.8% accuracy and AUC
equal to 0.89. On the other hand, in survival prediction, CBC at the diagnosis date gives
better evaluation metrics with 90.5% accuracy and 0.93 for AUC. The algorithms are
evaluated using CBC data collected and labelled by experts from Sultan Qaboos University
Hospital.
