About Ascires Biomedical Group

With a team of over 700 professionals, Ascires focuses its activity on precision diagnosis and individualised treatment. By volume of annual patients treated and medical technology, we are Spain’s leading biomedical group in Genetics, Diagnostic Imaging and Nuclear Medicine, as well as a benchmark in Radiation Oncology. We treat more than 500,000 patients a year in public and private hospitals where the group provides its Diagnostic Imaging and Genetics services and in our network of Ascires biomedical clinics.

With over 50 years of experience, Ascires reinvests 20% of its profits in R+D+i and dedicates an average of 65,000 hours per year to research. An investment effort that allows us to incorporate the latest advances in biomedical technology, both in Genomics and Diagnostic Imaging and Radiotherapy.

Ascires Biomedical Group is made up of three pioneering teams in Spain in their respective fields: the first massive genetic sequencing for clinical diagnosis (2009), the first magnetic resonance imaging scan (1983) and the first image-guided radiation therapy (2005). Our vocation is always aimed at making the latest medical advances accessible to the patient.

The biomedical group is currently applying Artificial Intelligence (AI), big data and Deep Learning to all its lines of activity with the aim of maximising the precision of diagnoses and treatments.
