Sarcoma develops from tissues like muscle or bone tissues.
There are two primary types of sarcoma:
1. Soft tissue sarcoma
Soft tissue sarcoma starts in the soft tissues such as fat, nerves, muscles, fibrous tissues, deep skin tissues or blood vessels.
Osteosarcoma is a cancer of the bone that usually affects the large bones of the arms or legs.
We are going to focus on soft tissue sarcoma in this section.
A soft tissue sarcoma may appear as a painless lump under the skin, often on an arm or a leg. Sarcomas that begin in the abdomen may not cause symptoms until they become very large. As the sarcoma grows larger and presses on nearby organs, nerves, muscles, or blood vessels, symptoms may include pain or trouble breathing.
