==Heart cancer == is an extremely rare. For example, one study reviewed more than 12,000 autopsies and found only seven cases of primary cardiac tumor. At Mayo Clinic, on average only one case of heart cancer is seen each year. Form of cancer that is divided into primary tumors of the heart and secondary tumors of the heart.

Causes
Oncologists continue to study the causes of cells malignant transformation and the occurrence of heart tumors. Despite the fact that nowadays, researchers cannot clearly identify the causes of heart malignant tumors, it has been revealed a genetic predisposition to this disease development. The cause of heart cancer may be hereditary syndromes. "Herzliya Medical Center" specialists in genetics can help to diagnose genetic relationship of the tumor and to determine the risk degree of the disease in the patient's immediate relatives.

Symptoms
Symptoms of heart cancer can resemble those of heart disease, such as chest pain, irregular heart rhythms, shortness of breath, and fatigue. Sometimes these symptoms develop suddenly.

Effects
Although still rare, most cancers found in the heart have come from elsewhere in the body. Cancers that begin near the heart, such as lung cancer, can grow to involve the heart or the lining around the heart (pericardial sac). Or cancer can begin elsewhere in the body and spread to the heart through the bloodstream. Cancers that may affect the heart include breast cancer, kidney cancer, lung cancer, leukemia, lymphoma and melanoma, among others.

Cancer can affect the heart in other ways, as well. A rare type of cancer known as carcinoid tumor at times produces hormones that can damage heart valves.

Treatment
Cancer treatments also can damage the heart. Cancer treatments linked to heart problems include several types of chemotherapy drugs, certain targeted therapy drugs, radiation therapy aimed near the heart, and hormone therapy. Some heart problems are detected during treatment, while others may not become apparent for many years after treatment. In many cases, the heart damage is reversible, though some types of heart damage can be permanent.
