Can there be cancer in the heart, the answer is yes, primary tumors of the heart are extremely rare, a case series study of over 12,000 autopsies identified only 7 primary tumors with an incidence of no more than 0.1%, in comparison, cardiac metastatic tumors are more than 20 times more common, according to the autopsy case series study, which reported that as many as 1 in 5 patients who died of cancer had a cardiac metastatic tumors. More than 75% of primary cardiac tumors are benign and can be cured surgically in most cases. The majority of benign lesions in adults are mucinous tumors; other benign tumors include hemangiomas, lipomas, malignant tumors, papillary elastofibromas, and teratomas, with rhabdomyosarcomas and fibromas being the most common in children. Mucinous tumors are most commonly found in the left atrium, accounting for about 2/3 of all cardiac mucinous tumors, followed by right atrial mucinous tumors, which account for about 1/5 of the total, while ventricular tumors and multiple cardiac chambers mucinous tumors are rare.
