Hello and hope you are doing well.
Understand your predicament. A biopsy of the lesion would be the next step. This will help to determine the type of tumor, the histopathological grading. Also, the extent of spread needs to be assessed with ultrasonography, CT Scan and blood markers. Based on this and the other co morbid conditions, the prognosis is determined. Discuss the possibilities with your consulting doctor.
Hope this helped and do keep us posted.
You should probably post this on the liver transplant expert forum. The doctor there is a transplant surgeon but he is extremely knowledgeable about all liver related issues.
Here is the link to that forum:

Good luck,
