Why cancer? Is it related to cancer?

You know cancer, so do you know the origin of its English name? Constellation knowledge answers for you. Cancer, Cancer-the only difference between these two words is whether the first letter C is capitalized or not. You must be curious: Why does the word cancer cross the fields of medicine and astronomy? What is the connection between these two seemingly unrelated interpretations?

About 400 BC, the ancient Greek doctor Hippocrates began to examine and treat patients with "advanced cancer". Of course, the word cancer didn't exist at that time. He named this almost incurable disease Karkinos, which means crab in Greek.

Then why is this disease called crab? There is a saying that the place where malignant tumors grow feels hard outside the skin, which reminds Hippocrates of crab shells. Others believe that the pain of cancer is like a finger in a crab's pliers, which is not only unbearable but also difficult to get rid of. Of course, these explanations are only guesses of future generations and cannot be confirmed.

Around 47 AD, when Celsus, an ancient Roman philosopher, compiled an encyclopedia in Latin, he translated the word karkinos into Latin cancer to name cancer. English also accepted this Latin name, which is still in use today.

A century later, the famous doctor Galen observed the breast tumor and found that the shape of it and its surrounding blood vessels was similar to that of the crab's feet around the crab's body. He also gave a more scientific explanation to Hippocrates' metaphor that the disease was called "crab".

As for Cancer, one of the 12 zodiac animals, its origin is also related to ancient Greece, but it appears in Greek mythology. Wikipedia says: When Hercules, the illegitimate child of Zeus, confronted Lehrner's hydra (Ophiuchus), Heracles' sworn enemy Hera sent a cancer to escape from the swamp and secretly attacked Heracles' feet. Hercules trampled it to pieces in a rage. Afterwards, Hera picked it up and rose to the sky, becoming a cancer.

The conclusion is clear! Here, the question is clearly answered: cancer means crab in Latin, and cancer and today's cancer are derived from its original intention-the former is related to the crab in ancient Greece, and the latter is related to a crab with a crushed shell in ancient Greek mythology.
