Can magick cause?

One of the basic rules of magic is that all things in the astral manifests in the physical world in some way, perhaps the physical manifestation for some demonic influences is cancer causing malignent radiation. Not saing that all cancer patients are bad peaple just on the astral level have come in contact with negative energy. I believe this is why exorcism was used as a cure because it banished the astral form that has manifested in the physical. But cancer could not be caused by simply doing magic because magical energy is different from radiation that causes cancer. In fact experiments with this magical energy also known as orgone by William Reich has caused cancer cells to become reccesive.
