What Is The Difference Between Carcinoma And Sarcoma
By definition, it is malignant (i.e., being locally invasive and at least theoreticlally capable of metastasizing), and arises from / mimics muscle or connective tissue elements that are not marrow or immune / white cells. The sarcomas are a tremendously varied and troublesome family of tumors, though thankfully less common than carcinomas and the leukemia / ...Read more
Different cancers: Sarcomas are very rare cancers that arise from bone, muscle, nerves, blood vessels or other connective tissues. Carcinomas are very common cancers that tend form glands. Most common examples are breast cancer, lung cancer, colon cancer, prostate cancer and renal (kidney) cancer, among others. ...Read moreSee 1 more doctor answer
Different origins: The suffix "oma" signifies a malignant lesion Since the body has various sources from which cellular and organ structures are derived different tumor types similarly arise. The epithelial cells comprising the tracheobronchial tree and those cells that comprise the lining of the GI tract form malignant lesions known as carcinomas. Those supportive cells of muscle, bone form sarcomas. ...Read more
Derivation: sarcomas arise from supportive tissues of the body. They are found in and derived from muscle, fibrous tissue and fascia, fat, nerve, blood vessel and bone. Spread is to liver and lung. Carcinomas arise from secretory and epithelial membrane spreading first to regional nodes as seen with breast, colon and lung. They respond differently to chemo. ...Read more
See below: Invasive carcinoma means the cancer has grown to the extent that it starts invading into surrounding tissue such as fat, fibrous tissue, lymphatics etc. Sarcoma is one type of cancer that arises from soft or connective tissue such as mucle, bone, blood vessels etc. It behaves differently from carcinoma which comes from lining of skin, ducts or internal organs. Surgery is primary treatment. ...Read more
No: I know no syndrome in which the two run together, but if they did both occur at a young age in the same person, i would suspect one of the cancer family syndromes such as li fraumeni. If there was otherwise a strong family history, or the person wished to make a decision about parenthood, then a talk with a geneticist would be in order. ...Read moreSee 2 more doctor answers
Yes they are: Sarcomas are embryo logically mesodermal tumors like muscle bones , supporting tissue etc, if they are not detected early and not treated they are just as bad as carcinomas, . They tend to spread by blood stream not by lymphatics , usually resistant to radiation. ...Read moreSee 1 more doctor answer
Usually random: Sarcomas are bone and soft tissue cancers. Generally, these occur because of random events in most patients. However things like radiation exposure can increase the risk of bone and soft tissue sarcomas particularly with higher dose radiation like used for treatment of other cancers. There are some genetic diseases like li-fraumeni that can result in getting a sarcoma and other cancers. ...Read moreSee 1 more doctor answer
Terminology: Forget the arcana of germ layers in cancer nomenclature. Sarcomas are cancers that have, for their cell of origin, a connective tissue cell -- bone, cartilage, undifferented mesenchyme, fat, smooth / striated muscle, endothelium. By convention, cancers arising from blood elements, lymphocytes and mesothelium are given non-sarcoma names. ...Read more
