Diagnosing Skin Cancer
Where does my skin sample go?
After our surgical team removes your lesion, it is placed in a specimen container which has a formaldehyde solution inside to preserve the tissue and characteristics of the specimen. It is then sent off to Perth laboratories with the specimen goes through a series of processing to determine a diagnosis at peter hsiao. The specimen is cut into thin sections and stained with special dyes, following this the pathologist views the slides under a microscope who reports on his/her findings. These findings are then reported back to your doctor, usually taking 2-3 days, who will then discuss with you the diagnosis and any further treatment methods.
