Sarcoma is the term for a group of different kinds of tumors that can form in the bones and in the soft tissue. The treatments vary widely, based on the location of the tumor and what type it is.
Sarcoma vs. Carcinoma
Sometimes it can be confusing since both Sarcoma and Carcinoma are malignant tumors that can both affect bones. So what’s the difference? The difference is that they are both made up of different types of cells that grow and spread differently.
Sarcomas grow like masses that look like balls, and they often push other structures (veins, arteries, and nerves) out of the way. These muscles also push into adjacent muscles and form a satellite-like projection of the mass, which is called a “satellite nodules.” These nodules are microscopic in size, compared to the actual mass.
- Sarcomas typically start in the bone, rather than traveling to the bone
- Sarcomas most commonly spread to the lungs
- Sarcomas also most commonly spread from one bone to other bones
- Sarcoma also can spread to the liver
Carcinomas grow through infiltration and very easily invade adjacent nerves, muscles, and veins. Their structure (shape) is less easily defined and therefore it is very difficult to remove it entirely with surgery because the extent of its spread is somewhat unknown. Carcinoma can very commonly spread to lymph nodes, bones, lungs and other organs, depending on the type of carcinoma. By definition, carcinomas can spread to bones, but they don’t originate in the bone. Unfortunately, a common scenario of carcinoma could be that a woman has her breasts removed, due to carcinoma, and several years later, have carcinoma show up in a bone tumor or elsewhere.
