That is a question I cannot answer for someone else. If I had a tumor in my liver, I certainly would do liver cleanses. In my personal opinion it is safer to release stones and toxins from the bile ducts and release the pressure on the suffocated liver tissue than letting the tumor grow.If medications are used, though, it is better not to cleanse it. It is difficult for the liver to release bile and stones while trying to trap drug chemicals in the bile and capsulate them into stones.
