WASHINGTON, Jan. 28, 2025 – Cancer accounted for nearly 10 million deaths in 2020 – almost one in every six deaths globally – according to the World Health Organization. Because the detection of abnormal diseased cellular growth often occurs too late, timely cancer diagnosis remains one of humanity’s most pressing and elusive medical objectives. Recent research has focused on the detection in peripheral blood of rare circulating tumor cells (CTCs), which serve as noninvasive markers that can help inform diagnoses. It is inherently difficult to separate controllable target cells to examine. Traditional ...

A new study published today in JAMA Network Open explores the effects of both recent and lifetime cannabis use on brain function during cognitive tasks. The study, the largest of its kind ever to be completed, examined the effects of cannabis use on over 1,000 young adults aged 22 to 36 using brain imaging technology. The researchers found that 63% of heavy lifetime cannabis users exhibited reduced brain activity during a working memory task, while 68% of recent users also demonstrated a similar impact. This decline in brain activity was associated with worse performance on working memory - the ability to retain and use information to perform tasks. For example, working ...
