3 HCC patients

For your patients with unresectable hepatocellular carcinoma Personalised and versatile TheraSphereTM Y90 Therapy


Preserve liver function while achieving tumour response3

Patient talking with doctor

TheraSphereTM Y90 Therapy has been shown to extend survival and provide predictable outcomes for patients with HCC. What is more, these benefits are obtainable without compromising on liver function.

Preserve liver function
