Why malignant tumors are called cancer

The name "cancer" comes from the term "carcinoma" (Greek καρκίνος - crab, cancer;), introduced by Hippocrates (460-370 BC), which denoted a malignant tumor with perifocal inflammation. Hippocrates called the tumor carcinoma, because it looks like a crab from the presence of outgrowths directed in different directions.

Roman physician Aulus Cornelius Celsius in the 1st century. BC e. suggested treating cancer at an early stage by removing the tumor, and at later stages - not to treat it at all. He translated the Greek word καρκίνος into Latin (cancer). Galen used the word ὄγκος to describe all tumors, which gave the modern root of the word oncology.
