Researchers call for urgent attention from health policymakers to address these issues and ensure accessible care.
A novel mutant gene variant of MLH1 significantly increases the risk of colon cancer among Israeli patients, with a 40-percent lifetime risk. Researchers discovered the gene in Sephardic and Ashkenazi Jews, Muslim and Christian Arabs, and other ethnic groups, suggesting its widespread presence globally.
A genome-wide screen reveals new functions for old genes associated with chromosome cohesion, a process keeping chromosomes together until cell division. The study identified 17 genes involved in this critical aspect of genetic material manipulation.
The HART study found HPV testing was more sensitive than cytology for detecting pre-malignant cells, but less specific. Surveillance at 12 months was as effective as immediate colposcopy for women with minimal abnormalities. This approach could improve detection rates of cervical cancer without increasing colposcopy referrals.
