A cancer pulse is usually double layered, but it can also be Concealed, Knotted, Substitutional, Choking, or Intermittent. When it is double layered, usually the very top it will be Knotted. Anytime a pulse is mixing with another one it will create a knotted sensation at the fingertips. When the cancer completely takes over, the whole pulse will become doubled and will look like two distinct layers. If the pulse is just knotting, then it means that something is blocking and growing, but if it actively doubling, then it is creating a malignant activity.
