Fighting Cancer Resistance: An Overview

Abstract

The inherent or developed resistance of many cancer cells to chemotherapy and irradiation is actually the main challenge to overcome in cancer treatment. It is well known that cancer cells are characterized by several hallmarks, and it seems that the ability to evolve ways to evade stressful conditions and killing therapies must be consider another typical characteristic displayed by all malignant cells. This overview aims to provide a concise description of the main mechanisms involved in the promotion of resistance to anticancer therapy and to describe the most frequent challenges faced in the war against cancer therapy resistance.
