heart cancer

What Is Heart Cancer?
Heart cancer is Fairly rare, and the muscle cells of the heart into the hands typically form cancers. Heart Cancer Can Be Visna primary or secondary. Primary heart tumors are not MALIGNANT, But Can Still Be Very Serious.
History
1st Cancer is a Condition Which in normal cells begin Growing rapidly. In ADDITION to expedited Their growth, cancerous cells RESPOND abnormally or not at all a Certain Cell Signals. Cancerous cells Also Can Gain Other Abilities, INCLUDING the ability to create Additional Blood Vessels and to migrate Throughout The Body.
Identification
2nd One of the Reasons why cancers are so heart Rare (a study of 12,487 Hong Kong autopsies found only 7 tumors of the Heart), That is the basic tissue of the heart does not Normally grow and divide. Since rapid cell division is one of the earliest steps of cancer development, this bridge Makes heart cells resistant to tumor formation. Nonetheless, CAN tumors originate in heart tissue (termed primary cardiac tumors) as well as spread from Theresa Another region of the body (secondary tumors).
Types
3rd The most common primary heart tumor is the myxoma. Their origin has Myxomas in Connective Tissue. A cardiac myxoma May create an extra heart sound, and it CAN OFTEN BE detected an echocardiogram. Most primary cardiac tumors are rare to metastasize and spread, as OFTEN SUCH They Are Called benign. Theses tumors can, however, be serious, as They Can obstruct the heart's flow as well as disrupt its electrical System, Which Can Lead to Sudden Death.
Effects
4th Secondary cardiac cancer is the result of a spread and metastasis from Another region in the points. Secondary heart tumors CAN resemble tissue from Other locations, and the new Will resemble tumor tissue from the region where clause the tumor began. Since theses tumors Already has spread, They Are Very Dangerous as They Can invade the heart tissue as well as spread to Other Areas of the body.
Prevention / Solution
5th One of the Difficulties of heart tumors is That, due to the fact That They occur on the heart, They Are Difficulty to Operate on. In ADDITION, radiation therapy is dangerous Because IT CAN Healthy heart tissue damage. Fortunately, primary tumors are rarely dangerous, secondary tumors, on the Other hand, are EXTREMELY Serious. Secondary cardiac cancer is fatal Generally Within Two Years of the diagnosis, as it rapidly invades the heart tissue, blocking normal blood flow off to the heart.
