It is becoming a public health problem due to its increasing prevalence. Some of the signs that occur with prostate cancer are: intermittent stream of urine, frequent urination, pain and burning when urinating, diagnosis begins with taking an anamnesis, followed by a digital rectal examination, PSA in the blood and prostate tissue biopsy. There are 4 stages of cancer. The treatment depends on the clinical picture, the tumor itself and its size, type and aggressiveness, but also on the patient, his age and state of health, and if the patient's condition allows, it is most often an operation. A nurse is an important person in the team that cares for a patient with prostate cancer. She prepares him for the surgery itself, where she focuses his attention on psychological support. After the operation, the nurse intensively cares for the patient, carries out education and provides support to him and his family until he is discharged home.
