Synonyms: lymph nodes
(LIMF glans) Lymph glands or nodes filter the lymphatic fluid (lymph). Some of the lymph glands closest to the prostate are the periprostatic, obturator, hypogastric, sacral and common iliac. Since these glands often capture prostate cancer cells that have migrated from the tumor, analysis of them can help to determine the stage of the cancer.
