biopsy

The ETH Zurich researchers analysed fat tissue biopsies from formerly overweight people who had undergone stomach reduction or gastric bypass surgery.

Then, a general dermatologist performed a physical exam using the visual appearance of the blemishes and a dermatoscope to make a diagnosis, and if needed, performed a biopsy.

He asked his doctors to remove it and conduct a biopsy, which came back cancerous.

Reaching this conclusion based on the biomarkers is like diagnosing cancer without doing a biopsy.

He said there had been a delay in getting biopsy results for Ms Turbill, which he said was because of a shortage of trained staff and staff-leave.
