Angiosarcoma is a rare and aggressive form of cancer that originates in the blood vessels, specifically the endothelial cells lining the walls of blood vessels and lymphatic vessels. This type of sarcoma can occur in various parts of the body, including the skin, soft tissues, and internal organs.
One of the distinctive features of angiosarcoma is its unpredictable and often rapid growth. It tends to be diagnosed at an advanced stage, which can make treatment challenging. The symptoms and manifestations of angiosarcoma depend on its location in the body. For example, skin angiosarcomas may present as bruise-like lesions, while those in internal organs may cause pain, swelling, or other organ-specific symptoms.
The exact cause of angiosarcoma is not well understood, but certain risk factors have been identified, such as exposure to radiation, certain environmental toxins, and a history of chronic lymphedema. Additionally, individuals with a compromised immune system may be at an increased risk.
Diagnosis typically involves a combination of imaging studies, biopsies, and histological examination. Treatment options for angiosarcoma may include surgery, radiation therapy, chemotherapy, or a combination of these, depending on the location and extent of the cancer.
Prognosis for angiosarcoma varies widely, influenced by factors like the tumor's size, grade, and how well it responds to treatment. Due to its rarity and the diverse ways it can manifest, angiosarcoma often requires a multidisciplinary approach to care, involving oncologists, surgeons, and other specialists.
