This book can be used as a basis for experimental research aimed at improving the health condition of patients who use chemotherapy and, consequently, may develop alterations that compromise their quality of life. We would like to pay tribute to Prof. Dr. Ronaldo Ribeiro (in memorian) for the opportunity to carry out this research at LAFICA/UFC. We hope that this reading will serve as support and encouragement to other researchers who, like us, are looking for new horizons.
