Let’s take a closer look at the structure and function of the lymph glands? The lymph nodes have a thin filter inside the membrane-enclosed outer wall. There are lymph nodes and lymphocytes that filter out the lymphatic fluid. This is called a lymph node, and it removes antigens that filter out various bacteria or foreign substances that have entered the body, as well as cells that can produce antibodies. If you look at the lymph glands a little bit, you think they’re really important organs that drive our health, right? To put it simply, it’s like a military police post and a cleaner responsible for detoxification and immunity? As such, normal functions serve as a sewer that discharges immunity and waste, but in the case of cancer patients, it is also a station where cancer cells pass.
