During the six-month follow-up, none of the participants developed infections and no serious adverse events were reported.

...at UCSF. Patients received repeat prostate needle biopsies at 12-24 month intervals, trans-rectal ultrasound (TRUS) every 6-12 months and PSA measurements every three months to track progression. Researchers defined progression as a change in PSA of greater than 0.75 ng/ml per year, increase in lesion size (...New mechanism identified for resistance to targeted lung cancer drugs

Some of the key findings relate to fibroblasts, which are in the dermis, the layer of the skin below the epidermis (outer layer). In young people, fibroblasts are stretched, and this produces enough ...Gene expression test reveals ER and HER-2 status of breast tumors
.... The samples included both fine needle aspiration biopsies and traditional biopsies. The team used 195 fine-needle biopsy samples to set gene expression thresholds that predicted ER-positive status with 90 percent accuracy and HER-2-positive status with 93 percent accuracy. They then applied those threshol...New screening process helps better diagnose oral cancers
