How did we understand a cancer patient's sudden verbal abuse of her caregiving son?

Her son requested help. He said his mother had cancer and poor health, and he watched her diet to avoid excessive oil and salt. She suddenly directed vicious words at him, very unlike her past behavior, frightening him. We visited the hospital to understand the situation and, considering unseen interference at the time, performed about fifteen minutes of energy infusion.

Her emotions later changed, and test readings that evening also fell. She was taking medication then, and I recall even the doctor being surprised. This remains striking in my memory, but illness still requires doctors, and religious help has limits. We considered unseen factors after understanding her circumstances. Sudden swearing by a cancer patient does not universally justify the same interpretation, nor does similar handling guarantee the same result for everyone.
