First, your body doesn't do anything to harm you, so there is nothing to be afraid of. However, fear of the unknown may manifest what you expect. Negative expectations are self-fulfilling prophecies. When they become fulfilled, they give us the idea that they would have happened anyway, as if we had no choice. But this isn't true. Although we often create what we fear through subconscious programming, we can change the programme.
Each negatively viewed situation like the bump on your hand can also be seen positively, or ideally, through the eyes of acceptance. When you accept something without turning it right away into something good or bad, you connect with it, and can thereby heal it. Healing is prevented, on the other hand when we fear what we perceive or imagine; simply because when you are afraid of something you also separate from it. When you are separated from it, you can neither connect with it nor heal it. Your body's cells go into protection mode and try to safe their energy, but this prevents them from growing and regenerating themselves.
Tumors of any kind are manifestations of fear = separation + protection. They heal spontaneously when your resistances disappears. When you consciously accept/embrace what or who you resist to (which are just reflections of the way you see yourself), not just the fear disappears, but also the body's cells can return to the more natural growth mode. Growth results in homeostasis or health.
The power of your thoughts, feelings and emotions is at least 10 times stronger than any physical influence can be. Stones in the liver or not, you are still more influential than they are. So don't fall into the trap of thinking the body is causing you problems that you cannot heal. Place both hands over your liver and say "thank you" to the cells of your liver and gallbladder, for they can hear you. Thanking the cells of the body is a powerful secret of healing, because the vibration of thank you connects what has been separated.
I am aware that this is not the answer you expected, but I feel that it will be of use to you.
