Soft tissue sarcomas are a group of cancers that arise from soft tissues in the body, such as muscles, fat, blood vessels, and connective tissues. They can occur in any part of the body but are most commonly found in the arms, legs, and trunk. These tumors can vary in size and may be benign or malignant. Diagnosis typically involves imaging tests like MRI or CT scans and a biopsy to confirm the presence of cancer cells. Treatment options often include surgery, radiation therapy, and chemotherapy, depending on the type and stage of the sarcoma. Early detection is crucial for better outcomes.
