Vitamin D had long been known for protecting bones, but its star began to rise in the early 2000s after researchers made connections hinting that vitamin D was good...

SAN DIEGO — Collecting cancer cells from patients and growing them into 3-D mini tumors could make it possible to quickly screen large numbers of potential drugs for ultra-rare cancers. Preliminary success with a new high-speed, high-volume approach is already guiding treatment decisions for some patients with recurring hard-to-treat cancers.

“Believe it or not, for some rare cancers...

James P. Allison of MD Anderson Cancer Center in Houston and Tasuku Honjo of Kyoto University in Japan have won the Nobel Prize in physiology or medicine for advances in harnessing the immune system to fight cancer.

All previous types of cancer therapy were directed at the tumor cell, but Allison’s and Honjo’s approach was to remove brakes that keep the immune system in check, unleashing...

Using gene editing, scientists have hoodwinked tumor cells into turning against their own kind.

Cancer cells circulating in the bloodstream have something of a homing instinct, able to find and return to the tumor where they originated. To capitalize on that ability, researchers engineered these roving tumor cells to secrete a protein that triggers a death switch in resident tumor cells...
