A new study of women with early stage, localized breast cancer identifies new patterns and risk factors for invasive disease that may influence how patients are treated. Published in the May 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study reveals that patients with lobular carcinoma in situ (LCIS) are actually at higher risk of developing advanced stage tumors than previously thought. In addition, women with ductal carcinoma in situ (DCIS) who are under 50 years old, African-American or Hispanic are at increased risk of developing advanced stage invasive tumors.
In situ lesions, such as DCIS and LCIS, are early generation cancer cells that have not yet invaded adjacent tissue. The diagnosis of DCIS and LCIS has been increasing up to 7-fold since 1980, according to U.S. statistics. The increase is hypothesized to be due primarily to more screening mammograms and breast biopsies.
The significance of these confined lesions in the course of breast cancer continues to be explored. Current research indicates that DCIS and LCIS clinically have different courses and prognoses, and consequently, should have different treatments. Oncologists recommend surgery for DCIS, considered a precursor to same breast invasive cancer. In contrast, observation after biopsy is recommended for uncomplicated LCIS, which is thought to have little invasive risk but may be a risk factor for later breast cancer. A few small studies have suggested that LCIS has a risk for same and contralateral invasive tumors, prompting some to recommend bilateral mastectomy in high risk patients.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
