Yttrium-90 釔-90
Yttrium-90 (90Y) is essentially used for therapy in nuclear medicine. Metabolic therapy comprises administering to patients a radioelement associated with a molecule which will preferentially focus on the tumour tissue in order to destroy it. Tumour-specific targeting helps increase the effectiveness of treatments while minimising harmful effects to healthy tissue. Yttrium-90 effectively fights certain lymphomas (so called non-Hodgkin's), cancers type that originates in the immune system (lymphocytes).
