worried, liver function elevation

Hello Dr, I'am currently waiting on my waiting on my appointment with you in April. In the meantime I have been worring myself over my recent blood work results. I have had elevated "Alt" for sometime since 2001. It has been around 65 to 80. I have ultrasounds 2002, 2004, 2006 and abdominal MRI middle of 2007 all normal except extensive gallbladder sludge on MRI and spleen hemangioma 1.6 cm. I had shoulder surgery in Jan torn labrum ("no I dont play for the Yankees") and had blood before the surgery alt 78 ast 47 alk 85 bil .08. I went for blood again on monday ( alt 103) ( ast 27 ) (alk 110) ( bil 09.) My ggt which i have only had tested once before in 2004 was "95" then and was" 264" on the most recent. The monday bloodwork was at a differentl lab then the ones used in the past. Concerned about liver cancer. Having some belching and slight discomfort under right rib cage.
