Why Is There No Incidence Of Heart Cancer?

Cancer is a tumor and tumors can be either benign (non-cancerous) or malignant (cancerous). Malignant tumors are further classified as primary or secondary, that is, whether it arises in the organ itself or spread from other organs. There are incidences of cancer of the heart and if it does occur it is usually benign such myxomas (the most common), fibromas, rhabdomyomas, and hamartomas. Malignant tumors of the heart such as angiosarcoma or cardiac sarcoma are know occur but are extremely rare. In fact any tumor of the heart is extremely rare. In a study of 12,487 cases where autopsies were performed only 7 tumors were found. Benign tumors of the heart can be surgically removed and the success rate is almost 100%. The success rate of the treatment of a malignant tumor of the heart depends on the further spread of the cancer to other vital organs.
