Recent scientific advances in the fields of genomics and bioinformatics are gradually changing the traditional medicine approach (disease detection and subsequent treatment) in favour of a predictive, preventive and tailored approach in healthcare and medical therapy.

Precision medicine, genomic medicine or 4P medicine (Predictive, Preventive, Personalised and Participatory) seeks to offer a more efficient and safe healthcare to patients, basing disease diagnosis, prognosis and treatment on the individual genomic/genetic biomarkers of each patient.
