Calcium is unique among metals because its ions have a very large concentration gradient across the plasma membrane of all cells, from 10 â3 M Ca 2+ outside, to 10 â7 M Ca 2+ inside.

Home > Cancer Resources > Relapse or Recurrence. Sometimes, despite the best care and significant progress made in treatment, cancer comes back. When this happens it is called a recurrence or relapse. The likely relapse occurs is that a few of the original cancer cells survived the initial treatment. Sometimes, this is because cancer cells spread to other parts of the body and were too small to be detected during the follow-up immediately after treatment.
