How much cancer is actually preventable, and what moves the needle most
A large US analysis attributed 42 percent of cancer cases to modifiable risk factors. One factor dwarfs all the others, and it is not diet.
Alcohol causes cancer at every level of drinking. Most people do not know it.
A 2025 US Surgeon General advisory put alcohol third among preventable causes of cancer. The global data show light drinking contributes too, not only heavy use.
Korea's gastric cancer screening works — until about age 70, on new national data
In 555,904 matched adults, screening endoscopy cut gastric cancer mortality in the 50s and 60s. Past 80, or with heavy comorbidity, the association reversed.
The alcohol flush is a genetic warning light for oesophageal cancer, not just a red face
An inactive enzyme carried by an estimated 540 million people lets a carcinogen build up when they drink. In heavy-drinking carriers, oesophageal cancer risk runs many times higher.
An off-the-shelf cancer vaccine provoked an immune response in every person who got it
Nous-209 targets 209 mutations shared across a whole class of tumours, so it can be manufactured in advance. What the trial has not yet shown is that anyone got less cancer.
A sequencing method accurate enough to count mutations one molecule at a time
Two Nature papers apply duplex sequencing with fewer than five errors per billion bases to cheek swabs and sperm — finding 46 genes under selection in mouth lining and a fatherhood risk that rises with age.
