To me, cancer cells smell like the culture medium used to grow them. I’ve grown billions of cancer cells for laboratory experimentation.

I wonder what substances the cells would be secreting to give a distinct odor.

I am no expert, but I have seen a documentary video demonstrating how they would have a dog check 20 or 30 jars, and would find the one with cancer cells placed in them. Don’t know how they obtained them, but it was a demonstration of the dog’s accuracy.
