This is for a friend. Her sister is terminally ill with breast cancer, their Aunt died of breast cancer, but they don't know their medical history for one side of the family as their mother was adopted. Apparently the type of cancer that her sister has, and her age, indicate that it could be genetic, but her sister has refused the test. My friend has been referred for an NHS appointment to get the ball rolling but was told it can take a really long time, so is mulling over going private, depending on how much it might be. Has anyone had it done privately?
