Hi I've posted on here before a couple times about different things, but this time I'm more worried I have a lump on both sides under my ribs I've told my about the one side because was getting pain, he said because of my age(18) he wasn't worried about it being cancer or anything but now I found the second lump on the left side about the same place the other one is and I'm scared I haven't got sick or anything but I get the odd pain that goes away....is this cancer
