extreme pain on right side

my wife has been getting these pains on her right side now for about 2 years.about one year ago she started having blood come out during her bowel movements, but that recently stopped.the pain was once a month or so but now it is every day.the pain is so intense that she almost can't bear it. they gave her vicodin es for the pain but it does not help.she has been seeing various doctors but each dr. says its something different.The last doctor says she has an enlarged liver, and also there is a growth of somekind in the liver about 1 cm. in size.possibly cancer. she had an ultrasound and a catscan, and they say she has no stones.Does anybody have any suggestions?
Does anybody reccomend flushes for this? any help would be great. Tweet
