A new study by Columbia University Irving Medical Center reveals significant differences in PSA (Prostate-Specific Antigen) and PSAD (Prostate-Specific Antigen Density) test measurements between Caucasian and Hispanic men. The study found that while PSAD can accurately predict cancer risk in Caucasians, it is less effective in Hispanic...

This method could significantly reduce the number of painful biopsies women undergo, with a recent study showing nearly 100% accuracy in detecting these regions.
Sentinel lymph node biopsy is a promising technique gaining popularity for breast cancer treatment. The new guidelines recommend infrequent surgeons not perform SLN biopsy, and positive results prompt full axillary dissection. However, SLN biopsy is contraindicated in patients with clinically palpable nodes, locally advanced breast can...
