Massage

My wife had a melanoma removed from the back of her knee last July. She was given the all clear for it but still has to be routinely checked every 3 months. She went to have a body massage today 05.04.19 that I had treated her to but the place refused to do it because of the cancer she had saying it was not safe to do so! Is this correct and if so will she be able to have a Turkish massage next month
