“Liposarcoma is a tumour that comes from fat cells in deep, soft tissue.”
Kind of amazing that they were able to find it.
I'm on the thin side - when I was getting an abdominal ultrasound to confirm that my gallbladder had turned into a beanbag, I asked the tech if the job's tougher when working on porkers.
She gave me a big "Hell yeah" and said they often use some 'markers' system to even find the various organs.
