MRI twice as likely as biopsy to spot prostate cancer, research shows

Researchers publishing in the Lancet medical journal have shown that an MRI picks up 93% of aggressive cancers, compared with 48% for a biopsy. The biopsy, which removes a sample of tissue for lab testing, often misses the tumour altogether. The Prostate MRI Imaging Study (Promis), led by researchers at University College London (UCL), also showed that more than a quarter (27%) of all men with suspected cancer could avoid a biopsy altogether.
