Researchers investigate low-intensity electrical pulses to help the immune system fight cancer

High-intensity electrical pulses have been medically used to destroy tumors while sparing healthy tissue. But lower-intensity pulses may have a different effect — they reshape the battlefield, making tumors more vulnerable to the body’s own defenses.

Researchers at Virginia Tech have discovered that these lower-intensity pulses alter the tumor’s environment, increasing blood vessel density within a day of treatment and boosting lymphatic vessel growth by day three. These changes may help guide immune cells to the tumor, potentially improving the body's natural ability to fight cancer.  Source: Virginia Tech News
