A protein that fuels cancer could also be the key to fighting it

Scientists have discovered how to turn a protein that normally fuels cancer growth into a weapon against it. By activating PPARD in immune cells, researchers made them better at burning fat and attacking tumors, slowing or stopping cancer growth in laboratory experiments. The approach showed promise against colorectal, breast, and ovarian cancers, as well as melanoma.

Cancer is rising in younger adults, and scientists can't fully explain why

A major study found that several cancers are rising faster among younger adults in England, even as smoking, diet, and other established risk factors have generally improved. Excess weight explains only part of the increase, leaving scientists searching for other possible causes, including changes in the gut microbiome and early-life exposures.

Pope lung nodule: Could it be cancer?

The case of Pope Leo shows how small lung nodules are often found during routine health checks. Quick treatment is generally advised before nodules can grow to become larger life-threatening masses.

Bowel cancer “melted away” after immunotherapy, then stayed away

A short course of immunotherapy before surgery may offer remarkably durable protection for some patients with stage two or three bowel cancer. In the NEOPRISM-CRC trial, 32 patients with a specific genetic form of bowel cancer received pembrolizumab for up to nine weeks before surgery instead of the usual post-surgery chemotherapy. After nearly three years of follow-up, none of the patients had experienced a cancer recurrence, including those who still had small traces of disease after treatment.

Scientists tested 5 natural compounds on cancer cells. One stood out

Five natural compounds, including curcumin and berberine, were tested for their effects on cancer cells and healthy muscle cells. All disrupted cancer cell energy production and pushed many of the cells into a non-dividing state, with curcumin producing the strongest overall effect. Curcumin also showed a relatively favorable safety profile, while some other compounds caused more toxicity.

Stanford scientists turn a cancer driver into a kill switch

A Stanford-designed molecule turns a major lymphoma-promoting protein against cancer cells, activating their own self-destruct machinery instead of simply blocking tumor growth. In mice, the treatment completely eliminated aggressive human lymphoma tumors within 11 days, although much more testing is needed before it could reach patients.

Cancer cases rising among young people, research finds

New major research has found that cases of several different types of cancer have risen sharply among young people in England, the United States, and the Netherlands. Researchers are not exactly sure why there has been such an increase, but say it could be linked to a growing rate of obesity, poor diets and a lack of exercise.

Cancer rates rising faster among younger people, international study finds

Major new research has found that cases of several different kinds of cancer have risen sharply among young people in England, the US and the Netherlands. The number of people under the age of 50 diagnosed with prostate cancer in England has quadrupled since 2001. Researchers aren't exactly sure why there's been such an increase, but say the broad reason could be linked to a growing rate of obesity, poor diets and a lack of exercise.
