Long-standing gallstones are associated with increased risk of gallbladder cancer It is better to have the gallbladder removed surgically in a planned manner as complications are unpredictable

Gall bladder stones dont go away just with medicines..also they can cause infection called cholecystitis or jaundice..once you form a stone..your body will keep forming new stones...better to go for a planned surgical removal of gall bladder
