👉 The Caroline fluid, named after Caroline Herschel who first described it in the 19th century, is a unique and rare bodily fluid found in women's breasts. Unlike milk, it does not have the same properties of being easily digested or absorbed by the body, which is why it remains in the breast tissue. The fluid is composed of a mixture of proteins, enzymes, and other substances, and its viscosity changes over time, becoming thicker and more gel-like as it ages. This characteristic fluid is believed to play a role in breast health, potentially providing some protective functions against breast cancer. However, its exact composition and biological significance are still subjects of ongoing research.
