Was the point of origin of [name withheld]’s breast cancer that she was murdered in a past life after sexual torture in which one of her breasts was cut off?

This indeed is the case and you were seeing this quite accurately from the akashic records. The incidence of cancer is a function of past trauma and this is not only emotional trauma per se but the totality of the human experience. There are often grave physical problems in the form of illness or injury at the hands of another, and this includes the self as well. All can be karmic predisposition for cancer and the expression of the illness is always traceable back to an inner conflict at an earlier point in time that left the person diminished in some way, largely with regard to their ability to control their circumstances and their destiny. This disempowerment is a key factor in promoting discord and a lowering of the basic well-being. When the energy of the karmic event re-emerges in a subsequent lifetime, it confers a resetting of many inner adjustments and alignments within the energy systems and this is read by the cells as marching orders and can send them into varying degrees of disarray. And with alteration of gene expression patterns, the problem can escalate. Normally, the cells are self-policing. They may auto-destruct or they may be attacked and cleaned up by the immune system looking for aberrant cells to remove as this is part of the so-called immune surveillance system to maintain well-being. The seeds of cancer and other tumors are sprouting within the body constantly, but do not reach the stage when they become discernible normally, but are beaten back and often cleared altogether. It is those with a strong karmic underpinning that persist and have the expression in a diagnosable illness.
