Ewing sarcoma is a rare cancer that most often starts in bone, but it can also begin in soft tissues. It belongs to a group of cancers called sarcomas, which develop from connective tissues such as bone, muscle, or fibrous tissue. It is commonly discussed in pediatric and adolescent/young adult oncology because it occurs more often in younger people, though adults can be affected. In clinical care, the term Ewing sarcoma is used to describe a specific tumor type with characteristic pathology and genetic features.

Osteosarcoma is a cancer that starts in bone-forming cells and produces abnormal bone tissue. It most often develops in the long bones, such as around the knee, upper arm, or hip. It is commonly discussed in orthopedic oncology, pediatric oncology, and sarcoma care. It is treated as a medical emergency in oncology because it can grow quickly and spread.

Bone sarcoma is a rare group of cancers that start in bone or the tissue around bone. It is different from cancers that spread to bone from another organ (bone metastases). The term is commonly used in orthopedic oncology, medical oncology, radiation oncology, and pathology. It is also used in imaging and biopsy reports when a primary bone tumor is suspected or confirmed.

Angiosarcoma is a rare cancer that develops from cells lining blood vessels or lymph vessels. It is a type of soft tissue sarcoma, meaning a cancer of connective and supportive tissues. It can occur in the skin, breast, liver, heart, and deeper soft tissues. The term Angiosarcoma is used in oncology, pathology, and radiology to describe this specific vascular cancer diagnosis.

Synovial sarcoma is a rare type of soft tissue sarcoma, which is a cancer that starts in connective tissues like muscle, fat, or fibrous tissue. Despite its name, it usually does not arise from the synovium (the lining of joints). It most often develops near joints in an arm or leg, but it can occur in many body locations. In cancer care, the term is used to describe a specific sarcoma diagnosis confirmed by pathology and molecular testing.

Leiomyosarcoma is a rare type of cancer that starts in smooth muscle cells. Smooth muscle is the involuntary muscle found in places like the uterus, blood vessels, and the digestive tract. Leiomyosarcoma is most often discussed in cancer care when evaluating a mass (tumor) in soft tissues or organs. It is commonly managed by multidisciplinary sarcoma teams that include surgery, medical oncology, and radiation oncology.

Liposarcoma is a rare cancer that starts in fat-forming (adipocytic) soft tissues. It is one of several cancers grouped as **soft tissue sarcomas**, which arise from connective tissues. Liposarcoma most often develops in deep tissues of the limbs or in the retroperitoneum (the back of the abdomen). In clinical care, the term *Liposarcoma* is used to describe a specific diagnosis that guides imaging, biopsy, staging, and treatment planning.

Soft tissue sarcoma is a group of cancers that start in the body’s soft tissues. Soft tissues include fat, muscle, nerves, blood vessels, and connective tissues that support organs and joints. It can arise almost anywhere, including arms and legs, the trunk, and deep spaces such as the retroperitoneum (the back of the abdomen). The term is commonly used in oncology, surgery, pathology, and radiology to describe diagnosis and care for these tumors.

Ependymoma is a tumor that develops in the central nervous system (CNS), meaning the brain or spinal cord. It arises from cells related to the lining of fluid-filled spaces in the CNS (the ventricular system and the central canal). Ependymoma is used as a diagnostic term in oncology, neurosurgery, and neuropathology. It is discussed in pediatric and adult cancer care because it can occur across age groups and locations.

A Spinal cord tumor is an abnormal growth that involves the spinal cord or the tissues around it. It can be benign (non-cancerous) or malignant (cancerous). It may start in the spine (primary) or spread from another cancer (metastatic). The term is commonly used in neurosurgery, oncology, radiation oncology, and neurology care.
