The study suggests that factors contributing to continued screenings include lack of awareness, physician enthusiasm for screening, ...
HIV-infected women are 3.9 times more likely to have HPV infection at the outset of the study, and smoking significantly increases this risk. Smoking and HIV infection may each alter the natural history of HPV infection to heighten tumor risk.
A survey of oncologists and nurses found that while most agree to offer trial results to patients, only 62% actually do so due to concerns over potential negative effects, patient interpretation, and resource consumption. Additionally, a new study demonstrates tamoxifen's association with reduced breast density, particularly in younger...
