Why Does the Immune System Sometimes Fail to Prevent Cancer?
Cancer cells often develop mechanisms to evade the immune system. Some can express proteins that inhibit immune responses, while others can create an immunosuppressive microenvironment that hinders immune activity. Moreover, cancer cells can mutate rapidly, making it difficult for the immune system to recognize them as threats. This ability to adapt and hide from immune detection is a significant reason why cancer can progress in the body.
