Certain breast lesions diagnosed as benign on core needle biopsy have cancer at surgical excision and thus should be removed, according to a study appearing in the March issue of Radiology.
"Our study shows that all papillary lesions of the breast should be surgically excised to avoid missing a cancer," said the studys lead author, Cecilia L. Mercado, M.D., assistant professor of radiology at New York University Medical Center in New York City.
Papillary lesions are benign growths in the duct of the breast. They comprise approximately 1 to 3 percent of all lesions sampled by core needle biopsies. Currently, the treatment of these lesions alternates between radiographic follow-up and surgical excision, and is often dependent upon physician recommendation.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
