i had a liver ultrasound done and it said that it was very fatty. Because of the excess fat, localized lesions can't be seen clearly but no mass lesions have been detected. Does this mean I do not have a tumor which in turns means no liver cancer?

I had the ultrasound done because I had elevated liver enzymes so my doctor suspects it to be the liver inflammed from fatty change. But after 3 months of exercising and dietary change my liver enzymes have returned to normal. Please let me know if the terminology from my ultrasound means no liver cancer. Thanks
