Abstract:
It is possible for tumors to develop resistance to currently used drugs. However, its increasing incidence necessitates further study and the development of novel therapies This review explores our current understanding of the factors that enable drug resistance, which include, inactivation of the drug, reduced drug uptake, increased drug efflux, metabolic effect, inhibition of apoptosis, epithelialmesenchymal transition, modified membrane transport, and heterogeneity of inherent tumor cell. This manuscript will also explore some genetic and epigenetic alterations that may encourage drug resistance and fundamental mechanisms of the reluctance of drugs in leukemia, ovarian and breast cancer and it concludes with a few solutions for managing drug resistance.
Insights
Tumor drug resistance is a growing problem. This review examines factors driving resistance, genetic changes, and strategies to overcome it in leukemia, ovarian, and breast cancers.
Area of Science:

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
