Re: Scared about liver cancer.
I think probably not. My gut feeling is a problem with liver cancer is that the liver has so much extra capacity that by the time liver has impaired it's function enough to show symptoms, it's way too late. So unlikely anything is going to show up in a short amount of time, certainly nothing that will produce symptoms.
The fatty liver and diabetes are more likely things to worry about. Cutting out Sugar, HFCS, and alcohol won't hurt you and may help.
Also recurring pain around your liver is more likely due to a gall bladder issue. Especially if associated with eating.
