The best part of a woman is her breasts. That's how I got the nickname "Breast Cancer".  I always cut them off.
This seems like a pretty dark joke to make in all honesty.
These comments are just a joke. I love all women and I would never remove their breasts in real life.
Whether you were making a joke or not, it is not a good idea to make jokes about someone having their body parts cut off. Things like this actually happen in our society today, so to make light of it is not a great idea.
