Breast cancer is the most common malignant disease in women, especially in the developed contries of the world. Glandular tissue is not limited only to the breast, thus a possibility exists that sometimes the mastectomy will not result in the removal of whole glandular breast tissue. The appearance of a painless lump on the breast is the most common indicator of breast cancer. Timely detection of breast cancer plays a decisive role in the recovery process. Breast cancer treatment can be performed locally and systemically The consequences of treatment can be grouped into three groups, namely: physical, psychosocial and spiritual consequences. The basis of the physiotherapeutic assessment is the SOAP protocol, which includes subjective assessment, objective assessment, measurement and testing, and creation of the therapy plan. Physiotherapeutic interventiones can be divided into three phases: early postoperative physiotherapy, late postoperative physiotherapy, and late physiotherapy. Lymphedema is a general term for a set of pathological conditions in which there is an excessive, regional interstitial accumulation of protein-rich fluid. In today's times, the possibility of recovery is significant, but it primarily depends on the time of the discovery, the stage of the disease and the possible presence of distant metastases.
