St. Joseph's Medical Center Begins New Lymphedema Prevention Program to Improve Care for Cancer Patients

(STOCKTON, CA) November 28, 2023  –  Dignity Health St. Joseph’s Medical Center, a provider of comprehensive cancer care to the San Joaquin community, today announced an innovative new program to reduce the impact of secondary lymphedema in breast cancer patients and survivors. The new program will assist breast cancer patients who are at risk of developing lymphedema from surgery, radiation, or taxane-based chemotherapy treatments.

“At St. Joseph’s we continually strive to provide the best possible care for our breast cancer patients,” said Arthur Hill, Director of St. Joseph’s Cancer Institute. “For us this means both delivering excellent care to our patients during treatment and after they have beat the disease. Breast cancer survivorship is growing rapidly as a result of improved treatments, and we are proud to be the first hospital in our market to offer lymphedema prevention as a service to our patients.”

Breast cancer-related lymphedema is characterized by buildup of lymphatic fluid that causes painful and sometimes debilitating tightness and swelling in the affected arm. There are over 290 thousand newly-diagnosed breast cancer patients every year in the U.S. and 80% are at risk of developing arm lymphedema.

The new lymphedema prevention program utilizes the latest lymphedema detection technology called L-Dex. L-Dex is a measurement of fluid buildup in an at-risk limb compared to a healthy limb and is measured on the SOZO® system, graciously funded by the St. Joseph’s Foundation of San Joaquin, which uses a sophisticated technology called bioimpedance spectroscopy (BIS). The SOZO test is non-invasive, takes less than 30 seconds to complete, and provides results immediately after the test. At-risk patients receive a baseline measurement and then are measured regularly after treatment.
