Angiosarcoma is a rare and aggressive type of cancer that originates in the blood vessels or lymphatic vessels. It can occur in various parts of the body, including the skin, breast, liver, and heart. This cancer often appears as a bruise-like lesion and can grow quickly, making early diagnosis important for treatment. Treatment for angiosarcoma typically involves a combination of surgery, radiation therapy, and chemotherapy. Due to its aggressive nature, the prognosis can vary significantly based on the tumor's location and stage at diagnosis. Regular follow-ups are essential for monitoring and managing this condition effectively.
