This is a quite perceptive observation, that if there is past karma that is targeting a particular organ system and then the symptoms are prevented by a surgical manipulation, not through a karmic repair directly, that the karmic insult will not have been addressed at all. If it is the case that the lesson was learned, alleviation of the symptoms may result in no further difficulty, because the point of karma is not to cause endless suffering but to provide sufficient learning for the individual to make a course correction in their life and do better going forward. This is why healing is possible and why the divine realm can intervene, in some cases, to take away even fatal illnesses that are looming, although not always. The difference is in what the individual needs to experience to gain the lessons, where they are in that sequence, and what the consequences will be of the divine realm stepping in to terminate the ongoing lessons. In this case, there is a transference of the karma to the other health issues and this continues to rumble, so the need for karmic repair is still ongoing. It is being addressed through divine healing by the Lightworker Healing Protocol work. It could be facilitated by doing the subconscious channeling work in addition and will speed the resolution of symptoms.
