Is it the cancer or the treatment that you're smelling?

It smelled like the cell culture lab. I wouldn't know what the treatment smelled like but it's possible the treatment might have smelled like DMEM.

This is my thought as well. A specific medication that is secreted when sweating, or an odour picked up during a treatment process.

Radiation therapy leaves a distinct oder I can detect.
