Since many patients do not receive a diagnosis until the disease has spread throughout their body, the prognosis for angiosarcoma is poor, states the Liddy Shriver Sarcoma Initiative. Angiosarcoma tumors are typically aggressive and grow quickly. Outcomes improve if patients have surgery to remove the tumors while they are small and the surgeon can obtain clear margins. Additionally, patients with low-grade angiosarcoma of the breast have a better prognosis than other angiosarcoma patients.
Diagnosis of angiosarcoma usually involves a physical exam along with imaging studies to determine the size of the tumor and find areas where it has spread, according to the Liddy Shriver Sarcoma Initiative. Biopsy is necessary to make a definitive diagnosis. Surgical removal of the tumor is the primary mode of treatment for angiosarcoma, but patients may receive chemotherapy and radiation in conjunction with surgery. After treatment, patients require close monitoring for up to five years.
Angiosarcoma is a cancer that affects the inner lining of blood vessels, reports the Liddy Shriver Sarcoma Initiative. The majority of angiosarcoma cancers occur in the skin, especially of the scalp and face, but other common areas of occurrence include the breasts, liver, spleen and deep tissue. In most cases, the cause of the disease is unknown, but one known cause is lymphedema.
