The heart is an extremely important and indispensable internal organ of the human body, which provides sufficient blood flow to all tissues and organs of the human body, supplies oxygen and various nutrients, and maintains the normal metabolism and function of the human body. If a tumor is found in the heart, it is definitely more dangerous and may cause a series of serious complications, which must be taken seriously and treated actively. Although cardiac tumors are rare in clinic, if the tumor grows in the heart, it may block the normal blood flow of the heart, causing heart failure as well as fainting, chest pain, arrhythmia, pericarditis, pericardial tamponade, etc. If the tumor and the thrombus embolus caused by the tumor dislodges, it may also cause circulatory embolism leading to hemiplegia, coma, sudden death and other serious complications. In addition to the heart, it can also cause fever, emaciation, anemia and other systemic manifestations. Surgical resection is preferred for early detected tumors or benign tumors, while malignant tumors may also require radiotherapy and chemotherapy.
