Cancer is a deadly disease which can occur in any organ of the human body ranging from an organ as small as the eye to something as big as the heart. The heart is the most vital part of the circulatory system in the human body. It pumps blood throughout the entire body by means of blood vessels by repetitive and rhythmic contractions. Heart cancer is one of the most unusual forms of cancer. It can begin its growth from any part of the heart. Heart cancer can be primarily divided into two types – primary cancers of the heart and metastatic cancers of the heart.

Primary cancers of the heart are the ones in which the malignant cancerous cells start their growth and further development inside the heart itself. This kind of heart cancer is very rare. Metastatic cancers of the heart are the ones in which the cancer originates in another organ or at any other location at first, and then gradually progresses and spreads to the heart. Though this type of heart cancer occurs more commonly than primary heart cancers, still it is also not a very commonly seen disease.

The commonest type of heart cancer in adults is angiosarcomas, which tends to develop in the right upper chamber of the heart. Angiosarcomas starts to originate from the cells which form the lining of the blood vessels. When these cells become cancerous, they proliferate and generate irregular blood vessel-like heaps which can swell and go into the atrium and can also spread to the adjoining structures.

The second most common type of primary heart cancer in adults is cardiac rhabdomyosarcoma. This type of cancer originates from the muscle cells which have become cancerous. Rhabdomyosarcomas can start building up at any place in the heart, but it almost always involves at least a part of the myocardium which is the thick muscular layer of the heart. This is also the most common type of primary heart cancer in children. Other less common kinds of primary heart cancers include fibrosarcomas, mesotheliomas, schwannomas, cardiac liposarcomas and fibrous histiocytomas.

The risk factors for heart cancer have not yet been identified as it is a very rare form of cancer. The common symptoms of heart cancer include: cough, irregular heartbeat, shortness of breath, chest pain, fever, sudden weight gain or weight loss, fatigue, swelling of the feet and ankles, etc. Various treatments are designed for heart cancer to control the symptoms and improve the patients’ quality of life.
