I would completely agree. Just recently had a patient who recurred in the lymph nodes underwent surgical resection and now will start adjuvant nivolumab. Had to have a very difficult discussion about discontinuation of breast feeding as well as future fertility as she really would like to have more children. Not a conversation that came easily.
I believe in the patients for whom this is applicable this will be an important discussion upfront and included in the pretreatment teaching as with any other expected side effect.
