Heart Cancer Overview

HRART CANCER

Primary cancers of the heart, where the cancer starts and develops in the heart are very rare. Metastatic tumors to the heart, where the original cancer elsewhere and spread to the heart, are more common than primary cancers of the heart are uncommon.
Cardiac tumors may develop from any of the heart. In adults, the most common tumors angiosarcoma of the heart, which usually develops in the right upper chamber of the heart (atrium). Angiosarcoma cells that make up the lining of arteries. When cells become cancerous, they multiply and create an irregular blood vessel-like masses, which can swell in the atrium, and spread to adjacent structures.

Cardiac rhaabdomyosarcoma cancer is the second most common primary heart in adults and cancer of the most common primary heart in children. These tumors are derived from muscle cells become cancerous. Rhabdomyosarcoma can develop anywhere in the heart, but almost always involve at least a portion of the myocardium, cardiac muscle thick. Less frequent types of primary cardiac tumors include cardiac liposarcoma, mesothelioma, fibrosarcoma, histiocytomas and schwannomas.
