Emerging research shows shift work disrupts the body's natural sleep cycles, impairing the brain's waste-clearing system and raising long-term risks of dementia, heart disease and certain cancers; scientists are studying whether planned naps and biphasic sleep could mitigate harm for millions of night workers.
A study in PLOS Medicine found prolonged sitting increases cancer risk and mortality, even for active individuals. Researchers tracked over 91,000 adults for 12 years, noting a 10% higher cancer death risk for every additional hour of continuous sitting.
Tom Hutchins, a 30-year-old business director in Hong Kong, was diagnosed with testicular cancer after noticing a small dot, not a lump. Early detection and his girlfriend's encouragement led to prompt medical attention, mitigating the shock of the diagnosis.
Amid European heatwaves, a social media claim suggests sunscreen increases skin cancer risk. DW fact-checked this, finding no scientific evidence to support it; instead, studies show regular sunscreen use reduces melanoma risk. Melanoma cases have risen since 1975, but this is not linked to sunscreen.
A study found HPV vaccination virtually eliminates cervical cancer deaths before age 30. However, falling vaccination rates in England could lead to hundreds of avoidable deaths annually, reversing progress towards elimination.
Recent studies suggest GLP-1 obesity treatments may reduce cancer risk, showing correlation with decreased incidence in 6 out of 7 cancers, potentially through anti-inflammatory effects beyond weight loss.
New research suggests GLP-1 agonists like Ozempic could cut breast cancer risk by 30%. A retrospective study found a significant reduction in incidence among women using these drugs, potentially due to weight loss and anti-inflammatory effects.
A study of nearly 112,000 women found those taking GLP-1 drugs for diabetes or weight loss had a 30% lower chance of developing breast cancer. Researchers suggest metabolic effects and weight reduction may inhibit tumor growth.
New studies presented at a major oncology conference suggest GLP-1 weight-loss drugs could reduce cancer risk by 30%. Research indicates they may lower the likelihood of developing breast cancer, decrease mortality risk in breast cancer patients, and reduce the spread of various cancers.
A new review suggests nicotine e-cigarettes may increase cancer risk by damaging DNA and causing chronic inflammation. While less harmful than traditional cigarettes, they are not risk-free, and long-term effects are still unknown. Experts recommend FDA-approved cessation methods over vaping.
A US study found that transplanting young gut bacteria into aged mice reduced liver inflammation and cancer-related changes. Treated mice showed decreased liver damage and no liver cancer cases, suggesting gut microbiota's role in aging and cancer risk.
Medical experts emphasize that lifestyle factors such as diet, physical activity, and regular screening are critical in preventing colon cancer, which is increasingly affecting younger adults.
A study presented at the American Association for Cancer Research conference suggests younger non-smokers who develop lung cancer consume more fruits, vegetables, and whole grains than the general population. However, experts have sharply criticized the research, calling it a 'stretch' that lacks a control group, uses arbitrary mutation groupings, and speculates about pesticides without data. Multiple experts noted the finding likely reflects that younger people and non-smokers tend to have healthier diets, and that leanness correlates with lung cancer. They emphasized decades of evidence showing fruits and vegetables lower or have no effect on lung cancer risk.
