Alcohol Metabolism
Alcohol and hepatitis B damage the same organ. Among hepatitis B carriers, the more they drink, the higher their liver cancer risk. This comes from observational studies (an association that cannot by itself show cause), but the direction is consistent and the mechanism is plausible.
Fatty Liver (MASLD)
Whether the upstream cause is the hepatitis B virus or metabolic fatty liver disease (MASLD), liver injury wakes stellate cells that lay down collagen, which builds up into fibrosis and then cirrhosis, and most liver cancers arise on that ground. Hepatitis B has an extra route: viral DNA integrates into liver cells, so cancer can develop even without cirrhosis.

Milk Thistle
No herb has been shown to clear the hepatitis B virus; pooling randomized trials in alcoholic liver disease and in hepatitis B and C liver disease, milk thistle had no significant effect on death or complications.

Why the virus can't be cleared

EVIDENCEGUIDE 2 · REVIEW 1

READ THE ORIGINAL

Drugs can hold hepatitis B down, but they almost never clear it. The reason is not that the drugs are weak. The virus has hidden its master copy inside the nucleus of your liver cells.

Once inside a liver cell, the virus's first important job is not copying itself but filing. It moves its loose, gapped ring of DNA into the nucleus, fills the gaps, closes it into a complete small circle, wraps it in proteins, and parks it beside your own chromosomes. This is covalently closed circular DNA (cccDNA), in effect a viral mini-chromosome (Nassal 2015). Every new batch of virus starts from it: the nucleus copies RNA off it, the RNA goes out to the cytoplasm, is reverse-transcribed back into viral DNA, and is packed into a shell and shipped.

The first-line oral drugs (nucleoside analogues such as entecavir and tenofovir) block the reverse transcription step. They can push the virus in the blood below detection, but they cannot reach the master copy in the nucleus. Stop the drug and the copying starts again, and the virus comes back (Nassal 2015; EASL 2017). That is why most people who start treatment usually stay on it long term.

If the skin or the whites of the eyes turn yellow, the belly swells noticeably, you vomit blood or pass black stools, or you become confused, these are signs that the liver is failing to cope. Seek medical care immediately.
