Once you have control over your sixth/super sense and subconscious mind, you may be able to revamp or regenerate your malfunctioning or dysfunctioning organs the same way as nails, hair, skin and liver get regenerated. An instruction from the super sense is passed to the subconscious mind to cure diseases like cancer, AIDS or hepatitis, etc., or to revamp a body organ, rest is the job of the subconscious mind to clear (cure) the instructed ailments from the body either by the available genetic and neurotic resources or by reconstructing new genetic or neurotic combinations.
With this type of sixth/super sense related mind power, you will also be able to control the speed of such revamping remedies and cures.
