Yes, cancer does have a certain smell from what I've heard, and dogs can detect it. We have one dog who has cancer, and all of the others are constantly sniffing him.

Years ago, I had a girlfriend who had breast cancer. We all went out to lunch, and as she turned to speak with me, I smelled the most horrible scent coming from deep within her throat.

It smelled like dead, rotting meat and once you smell something like that, you never forget it. I knew right then that she was dying.

We helped her go to a wheat grass clinic, and she lasted 3 more years.

OP, I hope your husband turns out to be okay. I sure do understand your worrying about this. Wasayo
