My suggestion is for you and other family members to take steps to prevent getting liver cancer to begin with. Keeping the liver cleansed, protected and regenerated would be good ideas, as would measures to make sure that the bile duct is kept open and flowing. Do those things, eat a healthy diet and live a healthy lifestyle and you should be in good shape. Cancers tend to fun in families for two reasons. One is genetics, though no one is genetically predestined to have cancer just genetically disposed to be more susceptible. The other reason is that families tend to have similar diets and lifestyles that may also make them more likely to get cancers. I think that often it is a combination of the two.
Here are some suggestions for the liver:
In addition to periodic liver cleanses.
Occasional Coffee enemas - help open the bile ducts so bile and toxins can be released properly.
Coconut oil - a wonderful item everyone should take, it helps maintain a good bile flow.
Beetroot juice - is also good for the liver and bile flow.
Turmeric - is a cancer fighter itself, especially for smokers, and it helps regulate bile flow.
Milk thistle - is a must as it helps protect the liver and actually regenerate it
Alpha lipoic acid - another liver supplement that also helps fight cancer
Selenium - a third liver supplement that is good against cancer too.
In the Berkson Clinical Study, three women who were facing liver transplants or chemo with interferon (a horrendous treatment with very low success rates for hepatitis and cirhossis), took milk thistle, alpha lipoic acid and selenium, modified their diets a bit and got some daily exercise and restored their liver functions to normal.
