Is your friend afraid or does she not like dr's just be her friend and tell her that you would be glad to take her in for a check-up or a mammogram and any=one knows that has ever has had the they are not very comfortable aand they do not show weather you have cancer 100% but they are a good place to start and they must have been invented by a man but you have to show her that you will be there for her and that she needs to start watching out for these things on her body , the longer she waits, the more trouble she might find.
Good luck to you and your friend! Remember that er are here for the both of you! But you also have to remember that you can lead a horsr to water but you cannot make them drink.
