While I strongly feel that breast cancer survivors' privacy and dignity are sacrosanct, I cautiously advise readers that in the case of most breast cancer survivors, "scars" are an emotionally necessary euphemism for consequences of life saving surgery that do indeed constitute physical irregularities. It is indecently cruel to dwell on this.

A scar that simply effects the skin usually will not register as an irregularity.

There's no need to believe that anyone's lying here.
