Besides malignant tumor and cancer, what other diseases are there?

There are differences. Malignant tumor is a general term, and cancer is just one of them. In medicine, tumors derived from epithelial tissues are called cancers, which mainly include body surface and visceral cavity surface, such as squamous cell carcinoma, adenocarcinoma, ductal carcinoma, hepatocellular carcinoma and so on. In addition to cancer, malignant tumors from hemolymph are called lymphomas, and those from soft tissues are called sarcomas, such as osteosarcoma, liposarcoma and fibrosarcoma. There are also some tumors from embryonic germ cells, such as yolk sac tumor and seminoma, and some tumors from mother cells are called * * * blastomas.
