In Croatia, 2400 new cases of this type of carcinoma are discovered each year. Since 2006, it has been considered the leading cause of death in Croatia, which led to the implementation of the national program for the prevention of breast cancer, including mammography for all women aged between 50 and 60. A person's age, gender, nutrition, positive family history, late first childbirth, stress, smoking, hormones, and mutations on the genes BRCA1 and BRCA2 are considered the main risk factors potentially leading to breast cancer. Physiotherapeutic procedures for patients with breast cancer provide therapeutic content in preoperative and postoperative rehabilitation. One of the main goals of physiotherapy is to improve the quality of life while performing diverse everyday activities. Physiotherapy also deems important preventing potential complications after surgical procedures, including lymphedema and posture deformations. A very common consequence of breast cancer treatment is in the shoulder area. Preventing adhesion with shoulder exercises after surgery should be started as soon as possible because restriction of movement in the shoulder joint occurs after the fourth day. The application of the PNF concept gives a positive effect on blood circulation, muscle endurance and ensures greater muscle relaxation in the shoulder girdle. Through a united collaboration between physiotherapists and patients diagnosed with breast cancer, it is possible to achieve great results.
