A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular ...
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
