Hi and welcome to HCM.
If you dont have hepatitis
or cirrhosis then possibility of having cancer isnt big,but those lesions must be evaluated. It can be localized fatty infiltration but also liver cancer
or metastases. You should do detailed work up including PET CT scan. What about your liver enzymes and bilirubin
. If this is raised then something is wrong obviously. Your drugs can cause liver damage
but wouldnt cause focal lesions.
Wish you good health.
