All your issues will not go away with one fast. All unwated tissues, tumors, , fibroids, toxins are eaten by the body by the process of autolysis.
You have to be patient and finish one fast. Then plan a good nourishing plan and then fast again. I would use the doctors for teesting anything that you need to, but use fasting to heal and clean.
Remember, everyone here says, it did not take a few days to accumulate the problems, porbably took may moths and years, so it will as long or longer to heal.
