Spindle cell sarcoma

Spindle cell sarcoma is a type of

stage 1, and will not necessarily expand beyond its encapsulated form. However, it may develop cancerous traits that can only be detected through microscopic examination or cell-level molecular analysis. As such, at Stage 1, the tumor is usually treated by excision, which includes wide margins of healthy-looking tissue, followed by thorough biopsy, and additional excision, if necessary. The prognosis for a stage 1 tumor excision is usually fairly optimistic, but if the tumor progresses to levels 2 and 3, prognosis worsens, due to tumor cells' likely having spread to other parts of the body, including nearby healthy tissues, or to system-wide locations that include the lungs, kidneys, and liver. In these cases, prognosis is grim and chemotherapy and radiation

are the only methods of controlling the cancer.

A variety of factors influence the incidence of spindle cell sarcoma, including genetic predisposition, but it may also be caused by a combination of other factors, including injury and inflammation in patients who are already thought to be predisposed to such tumors. Normal spindle cells are a naturally occurring part of the body's response to injury.^[citation needed] In response to an injury, infection, or other immune response, the spindle cells of connective tissue will begin dividing to heal the affected area; if the tissue is predisposed to spindle cell cancer, the high cellular turnover may result in a cell mutating, becoming cancerous, and forming a tumor.
