How many types of malignant tumors are there?

Types of malignant tumors:

Almost any part of the human body, any tissue, can develop tumors.

According to the origin of the malignant tumor, those that grow from epithelial tissues such as skin, mucous membranes, and glands are called cancers.

Such as gastric cancer, liver cancer, lung cancer, esophageal cancer, cervical cancer, breast cancer, colon cancer, rectal cancer, nasopharyngeal cancer, ovarian cancer, renal cancer, bladder cancer, thyroid cancer, and skin cancer.


Sarcomas are malignant tumors that arise from mesenchymal tissues such as muscle, fat, bone, blood vessels, and lymph. Examples include rhabdomyosarcoma, leiomyosarcoma, fibrosarcoma, liposarcoma, osteosarcoma, chondrosarcoma, angiosarcoma, lymphosarcoma, and kaposi sarcoma.

Specially named

There are also some malignant tumors which have alternative names due to historical reasons, such as leukemia, Hodgkin’s lymphoma, Wilms’ tumor, melanoma, retinoblastoma, testicular seminoma, granulosa cell tumor, Krukenberg tumor, Ewing’s tumor, malignant vascular endothelial tumor, and Paget’s disease of the breast.

Since cancer is far more common than sarcoma (and other malignant tumors), approximately 9:1, meaning that out of 10 patients with malignant tumors, 9 have cancer and 1 has sarcoma. Therefore, malignant tumors are generally referred to as cancer.

There are 62 types of human cancer according to the International Classification of Diseases, with the highest incidence rates being digestive system cancers and respiratory cancers, such as gastric cancer, liver cancer, lung cancer, esophageal cancer, colorectal cancer, etc.
