Patients with multiple tumors in the same breast who underwent a lumpectomy followed by radiation therapy had local recurrence rates comparable to those historically observed in patients with a single tumor, according to results from the ACOSOG Z11102 (Alliance) prospective phase II clinical trial, which were presented at the San Antonio Breast Cancer Symposium, held December 6-10, 2022.
Many women with two or three breast tumors can get by with lumpectomy surgery instead of having their whole breast removed, a new study suggests. In recent years, more patients with multiple tumors have been identified, a result of more sensitive imaging techniques that can reveal tiny, once-hidden cancers. To take part in the study, their tumors had to be less than 5 centimeters and separated by 2 to 3 centimeters of normal breast tissue.
In an article published in the journal Applied Sciences, researchers designed a long wavelength infrared imaging optical system with a large relative aperture.
In a study using specialized imaging techniques, Johns Hopkins Medicine researchers report distinctive changes in the "white matter" and other brain tissue physiology of those with post-treatment Lyme disease, a condition affecting 10% to 20% of the nearly half a million Americans who contract Lyme disease annually.
