question: I have a 4 cm gallstone.  Should it be taken out if I dont have many of the usual symptoms.  I am 65 and my dr. says that I have probably had it a long time.  I dont hurt when I eat a fatty meal or a big meal.  Right now I keep having a pain just about the area of my right bottom rib cage.  It has been there for about 4 months. I weigh 150 pounds and am female.
