This is interesting...I certainly heard of dogs smelling cancer on their owners. Sometimes it's the first clue one does have cancer...
First, I remember when my brother (unknown to us, at first) was developing lung cancer. His wife said his breath was horrendous! She couldn't stand to be in the car with him, it was that bad.
Second, I have noticed many times my urine had an off-smell. Someone said like "cat pee" and I would agree with this as well as the ammonia smell. I thought it was a result of all the medications I take. I had my bilateral mastectomy in May 2025. But occasionally I still smell it in my urine. I had one positive lymph node...I am going to try the spoon test. Since my concussion and subsequent development of migraines my sense of smell is really sharp. Thanks for sharing this "oddity??" everyone.
We all can't be crazy, there is certainly something to this - the smell of cancer.
