What is the prevalence of cardiac angiosarcoma?
Cardiac tumors occur as primary tumors or tumors that arise from the heart tissues themselves or secondary tumors which are tumors that have spread (metastasized) to the heart. Secondary tumors are 20-40 times more prevalent than primary tumors. Of the primary tumors, 75% are benign and 25% are malignant. Of the malignant tumors, about 75% are sarcomas. Primary malignant tumors of the heart occur about 1 in 10,000 people. Angiosarcomas are the most frequent cardiac sarcoma occurring. |
