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. FRANCE 24's Sharon Gaffney speaks with Jon Shelton, Head of cancer intelligence at Cancer Research UK.

MIT scientists find a hidden cancer risk of the keto diet

A ketogenic diet increased small-intestinal tumors in cancer-prone mice while reducing tumors in the colon, revealing a strikingly different response within neighboring parts of the gut. Researchers traced the increased risk not to ketones, but to the way intestinal stem cells processed the diet’s high levels of fat. That fat-burning activity pushed the cells to multiply more rapidly, potentially raising the chance of cancerous changes.

Colorectal cancer is rising in young people and often found too late

Colorectal cancer in young people is often diagnosed at an advanced stage, with researchers finding most patients age 21 or younger already had Stage III or IV disease. Because symptoms like rectal bleeding, weight loss, abdominal pain, and bowel changes may be overlooked, researchers are calling for greater vigilance.

Cancer-fighting t cells burn out. Scientists may have found a fix

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn through their energy while producing cancer-killing proteins. In animal and laboratory studies, blocking MEK helped the cells conserve energy, survive longer, and remain active even in the harsh environment around tumors.

Breast cancer: the post-tests

Started on October 1st of the new Pink October campaign. The objective remains the same: to raise awareness of breast cancer and to recall the importance of screening. In 2026, the same is true: the disease is getting better and better, but it continues to progress. Especially among young women.

One in eight cancers worldwide linked to infections, WHO agency says

A new study from the International Agency for Research on Cancer (IARC) shows that an estimated 2.3 million new cancer cases worldwide in 2024 – about 12% of all new cancer cases – were caused by infections and could be prevented with treatment or vaccines. FRANCE 24's Jennie Shin speaks with the lead author of the study, Dr Gary Clifford, Scientist at the IARC.

A major risk of breast cancer screening may have been overestimated for decades

A new analysis suggests mammograms may lead to far less breast cancer overdiagnosis than some earlier studies indicated. Researchers reexamined all eight major randomized screening trials and accounted for differences in follow-up time, screening frequency, and screening after trials ended. Their results were consistent with an overdiagnosis rate below 5%, rather than estimates approaching 30% to 50%.
