My mother, after a recent stroke, developed an ovarian cyst which was benign thankfully, and two cataracts for which she awaits surgery. Suspiciously, I think there's a connection. However, she has never delayed in getting treatment even though she dislikes doctor and hospital visits, and this is the key for her. Get treatment, get it now, fight with all your might, and get over any reluctance.Wish your friend well.
Peace, Mooh.
