Breast cancer is one of the most common cancers among women in the United States. Thanks to decades of fundamental research, it's also one of the most curable. The exception is a particularly aggressive variant known as triple-negative breast cancer (TNBC). It accounts for 10% to 15% of all breast cancer cases. It disproportionately affects younger and African American women.

Millions of people are expected to lose access to Medicaid and Affordable Care Act marketplace health insurance plans if federal lawmakers approve the One Big Beautiful Bill Act, President Donald Trump's domestic policy package, which is now moving through the Senate.

In the fight against cancer, immunotherapy—which aims to boost the body's natural defenses against cancer—is experiencing remarkable growth. Most of these treatments are based on CD8 T lymphocytes, "killer cells" able to eliminate diseased cells. A team from the University of Geneva (UNIGE) has explored an alternative approach involving CD4 T lymphocytes.

As public health insurance in the United States faces potential cuts, a Rutgers University review of medical records finds that Medicaid and Medicare patients with opioid addiction tend to receive behavioral health care services less often than those with other types of funding.

President Donald Trump's One Big Beautiful Bill Act, sprawling legislation to extend his tax cuts and enact much of his domestic agenda, would require 40 states and the District of Columbia, all of which expanded Medicaid, to add a work requirement to the program.

California lawmakers are poised to delay the state's much-ballyhooed new law mandating in vitro fertilization insurance coverage for millions, set to take effect July 1. Gov.

In radiation therapy, precision can save lives. Oncologists must carefully map the size and location of a tumor before delivering high-dose radiation to destroy cancer cells while sparing healthy tissue. But this process, called tumor segmentation, is still done manually, takes time, varies between doctors—and can lead to critical tumor areas being overlooked.
