I have found that on this site it is never wrong to ask anything or say what ever you want. We are all in this together & can only try to help & support each other as best we can.
I don't think there is any way to truely understand this horrible type of cancer. Believe me, I have tried. It seems to affect everyone differently & treatments that work for some do not for others. I too have been angry at times & wondered why things happened the way they did & why others have more success with both diagnoising & treating it.
In my husband's case, it was intrahepatic & confined to the bile ducts of his liver. Unfortunately, by the time he was diagnoised it was in 95% of the liver. He didn't even have a fighting chance. Up until his first symptoms, which presented only 7 weeks before he passed on, he was a normal, happy, healthy man. Obviously, the cancer had been there for a long time, but there were no symptoms. We didn't have a clue.
I'm not sure how helpful this will be to you or if it will just confuse you even more, but I just wanted to tell you how it was for him.
Hopefully in the future there will be more answers & some day even a cure for this horrific disease.
