Increased role for PET imaging could improve cancer care

PET imaging has shown to be a valuable tool in improving cancer care management by accurately assessing treatment outcomes and monitoring tumor response. Studies have demonstrated that PET can detect residual scar tissue rather than viable tumor, leading to changes in how PET is used in cancer care.

Soaring UK rates of Chlamydia infection partly caused by more sensitive tests

A study found that more sensitive Chlamydia testing led to a significant increase in reported cases, with a 62% jump in female infections and a 56% rise in male infections between 1992 and 2003. The shift from culture tests to nucleic acid amplification testing (NAAT) is believed to be the primary cause of this increase.
