we have heard cancer affecting a number of organs of human body.. but nobody heard a HEART CANCER ...WHY..?

Answer 1

1. It's probably evolution. Since the heart is a vital organ, it's not hard to imagine heart cancer being fatal. That probably means long ago if anyone was susceptible to heart cancer, they would've just died off before breeding.
2. The lungs, skins, breasts, and other body parts that usually get cancer are exposed to the outside world to get damaged. The heart is nestled snugly in your body with little outside contact to hurt it.

Answer 2

There is such a thing as cancer of or on the heart. The reason you don't hear about it very much, is because it is pretty rare. In most cases, a tumor on the heart is diagnosed early because the symptoms appear very rapidly. A tumor changes the way the heart pumps blood, and you know it pretty quickly. Surgery is the preferred treatment because chemotherepy damages tissue, and with the heart that's usually fatal. The most common tumors of the heart are in the heart valves, which in some cases can be removed, other cases replaced. Laser surgery has proved effective in vaporizing tumors without damaging the surrounding tissue, but with cancer there is no such thing as a "sure thing". In any case, it's VERY serious.

Answer 3

Cancer of the heart muscle called angiosarcoma do occur but are rare and occur more often in children and more often in the right side of the heart.Cancers like melanoma are known to spread to the heart. That being said, it is somewhat curious why certain tissues are less susceptible to cancer. This is typically ascribed to the belief that the more cells that are actively dividing in an organ or tissue the less likely that organ or tissue will have a cancer arise in it. So skin, intestine and bone marrow which have high populations of dividing cells are more often to have a cancer arise in their cells than the heart whose muscle tissue is essentially non-dividing.

Answer 4

Heart melanoma is an enormously infrequent sort of melanoma. Heart melanoma is split into principal tumors of the guts and secondary tumors of the guts. Most middle cancers are benign myxomas, fibromas, rhabdomyomas and hamartomas, even though malignant sarcomas (corresponding to angiosarcoma or cardiac sarcoma) were identified to arise.... In addition the guts may also be suffering from cure for melanoma in different elements of the frame.

Answer 5

Heart melanoma is an incredibly rare type of melanoma. Heart melanoma is divided into essential tumors of the center and secondary tumors of the heart. Most coronary heart cancers are benign myxomas, fibromas, rhabdomyomas and hamartomas, despite the fact that malignant sarcomas (equivalent to angiosarcoma or cardiac sarcoma) have been identified to occur.... In addition the heart will also be suffering from cure for melanoma in different components of the physique.

Answer 6

Cancers of heart are of several types.1)Sarcoma 2)Lymphoma 3)Metastatic ones like Melanoma etc..But most are diagnosed very late ( a week before death or post mortem).

Answer 7

of course there is a heart cancer ....and its called angiosarcoma .and it effects the children mostly... though it is not really that common....there is a 1 in 1300 case rate....and most infants don't survive it...

Answer 8

There is heart cancer, but it is rare.
