My father died July 5th of what doctors are saying was Malignant lymphoma of the liver. They said his liver was 4 times the normal size, hard as a rock, and no blood when they cut to do the biopsy.
My father was the picture of health, up until 2 weeks before he died, and then only had mild flu like symptoms, and kept saying that he was very tired.

My questions are, why were there no symptions, if his liver was so bad? How long could he have had this with no symptoms? We have no family history of cancer. This was a man who was a casual drinker, ate mostly fruits and vegetables, salads. Any one that could enlighten us would be wonderful, we are just blown away and would like to understand more.
Thank you
