Two tests may be better than one.
That’s the conclusion of researchers in a new study that looked at the reliability of both ultrasounds and mammograms. Where mammography is available, ultrasound should be seen as a supplemental test for women with dense breasts who do not meet high-risk criteria for screening MRI and for high-risk women with dense breasts who are unable to tolerate MRI.
However, mammograms expose women to small doses of radiation. Also, it may miss masses in dense breasts. Breast ultrasound has its advantages, too. The technician may look for lesions hidden within dense breast tissue (parenchyma). There’s no radiation involved. How effective an ultrasound exam depends on the skill of the person performing it.
Human error can lead to overlooked lesions or misinterpreted results. But unlike mammography, ultrasound can’t make out architectural distortions, calcifications, or asymmetries. There is also a higher false-positive rate of ultrasound compared to mammography. False positives often lead to more tests, including biopsies. That can add to healthcare costs.
The risk is so low that it is impossible to read using tables of published health data and statistics. Children do get cancer, but very rarely breast cancer. Statistics will often group women aged 15–39 as “young women” but this is very misleading as the bump in cases begins in women over 20, or eve....

Yes, PARP inhibitors are relatively newer class of drugs and scientists have just begun to explore their functionality and usage in Cancer treatment. LYNPARZA is the first and only PARP inhibitor approved in 2 distinct settings: For the maintenance treatment of adult patients with recurrent epitheli....
