but also constitute a substantial component of liver

people seldom heard of cardiac cancer, cancer of the spleen, is this why?

No epithelial tissue

heart

heart as the hub of human organs and cancer insulation for several reasons:

first, and the organization structure of the heart. Epithelial tissue covering the surface of the human body, but also covers the inner surface of the digestive tract, respiratory, urinary, reproductive tract, but also constitute a substantial component of liver, kidney, breast, prostate and other organs. Cancer is a malignant tumor of epithelial tissue, no epithelial tissue in the heart, so there will be no primary cancer.

second, the heart and Cheap Chelsea Jerseys blood vessels constitute a closed circulatory system, make it less susceptible to direct Cheap Italy Soccer Jerseys attack outside harmful substances.

In fact, the heart is not absolutely not cancer, angiosarcoma, rhabdomyosarcoma, lymphoma, malignant tumors can occur in the heart; in addition, melanoma, renal cell carcinoma, lung carcinoma, choriocarcinoma, breast cancer can also be transferred to the heart, become secondary to malignant tumor. However, whether primary or secondary, compared with other organs, the heart is still very rare malignant tumor.
