Until now, however, cancer optimal therapies have considered that malignancy exclusively depends on the drug concentration and the number of cancer cells, ignoring that the faster the cancer grows the worse the cancer is, and that early drug doses are more prejudicial. Here, we analyze how optimal therapies are affected when the time evolution of treated cancer is envisaged as an additional element determining malignancy, analyzing in detail the implications for imatinib-treated Chronic Myeloid Leukemia %K Optimal control problem %K Time valuation factor %K System of difference equations %K Chronic myeloid leukemia %K Hematopoiesis %K Imatinib therapy %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6540446/
