I have my husband who has bile duct cancer and its in his liver now and the branches of the liver his numbers are now 5,300 how high dose it have to be before he dose not survive this. they said less than a year which im taking it to be 3 to 6 months at the most. just last week or so he started turning yellow again but it kinda lighten up. he has stents in. but, they said the cancer is narrowing the opening for bile to flow. and the stents will get blocked as well. his skin color dose not look good to me and he is having pressure and takes pain pills what do you think he might have left in months.
