Breast cancer is a malignant tumor that originates in the mammary gland's cells that grow locally in the breast metastasizes to the lymph nodes and internal organs (lungs, liver, bones and brain). Over 23% of cancer cases in women in Poland and the world are breast cancer. Techniques for irradiating breast cancer have developed continuously in recent years. The study aimed to present the radiotherapeutic techniques used in irradiation of breast cancer - from two-dimensional 2D static to dynamic techniques (IMRT intensity modulated radiation therapy, VMAT volumetric modulated arc therapy) up to DIBH deep inspiration breath hold. The paper focuses on implementing the given techniques and describing the influence of a given technique on the dose distribution in the Planning Target Volume (PTV) and doses in critical organs in breast cancer radiotherapy.
