A new study by researchers at UC San Francisco found that heart scans are only useful in prescribing statins to patients at high risk of coronary heart disease who are taking expensive statin therapy. The CAC test can save money on statin costs but may not prevent as many heart attacks, the researchers concluded.
Research from Umeå University and Memorial Sloan Kettering Cancer Center found that frequent PSA testing in areas with high incidence rates results in lower prostate cancer mortality. However, this is offset by increased risk of overtreatment, which can lead to side effects such as erectile dysfunction and urinary incontinence.
A new glycoprofiling test has been developed to halve the number of false-positives in ovarian cancer diagnoses, sparing women from unnecessary worry and further testing. The test targets a specific sugar molecule on the CA125 protein, which is only present in women with ovarian cancer.
