Show all keywords - [cancer](< /en/search?q=cancer >) - [Comprehensive Cancer Center](< /en/search?q=Comprehensive Cancer Center >) In the Molecular Radiotherapy Unit of the Comprehensive Cancer Center, we provide intracorporeal targeted radiotherapy. Our Molecular Radiotherapy Unit specializes in radiation therapy, where the source of radiation migrates to the colony of cancer cells with circulation and destroys cancer cells. We carry out some of the unit's treatments as outpatient care and some as inpatient care due to the radiation isolation required for treatments. We develop and carry out radionuclide therapy in collaboration with various experts such as physicians, physicists, pharmacists, and nurses. In addition to gamma camera and SPECT computer tomography scans related to treatments, we also conduct studies to determine the prevalence of cancer or the functioning of a particular organ. ## [ Care pathways for cancer ](/en/patient/treatments-and-examinations/cancer) The care pathways offer reliable information on various types of cancer, the related diagnostic tests, and the different stages of care at HUS.
