INTRODUCTION From the time of the physician Galen (2nd century AD) in his work "On the causes of symptoms" the term "tumor" is used, denoting to this day the pathological mass of cells. Terms such as cancer, tumor, mass, malignancy, mutation as well as names such as "incurable disease" are used for oncological diseases causing many confusion for both health professionals and patients and attendants. According to the World Health Organization, cancer is one of the leading causes of death worldwide and even 70% in low-income countries. In Greece it is the second leading cause of death after cardiovascular disease. It is also worth mentioning that both the disease itself and the treatment followed, can lead to emergencies. "An oncological emergency (EOP) or problem or event is defined as any acute, life-threatening condition of a patient that is directly or indirectly associated with cancer or anticancer therapy." The purpose of this study is to highlight the oncological emergencies of cancer patients due to either the disease itself or the treatment.
