What is Ewing Sarcoma?
Ewing Sarcoma Defined Ewing sarcoma is a cancerous bone tumor that affects children, adolescent and young adults—usually developing during puberty between the ages of 10 and 20 years old. Approximately 87% of Ewing sarcomas are in the long bone, meaning the arm, thigh, shin and pelvis. On rare occasion, Ewing sarcomas can occur in soft tissue like cartilage or nerves. These are called pPNET tumors and can be found in the nerve tissue in many parts of the body; if a pPNET is found in the chest,...
What is Rhabdomyosarcoma?
Rhabdomyosarcoma (RMS) is a type of soft tissue cancer that most commonly affects children and adolescents. It’s often found in skeletal muscle tissue or organs, such as the head and neck area, the urinary system, the reproductive system or appendages like the arms and legs. Rhabdomyosarcoma is part of a larger grouping of cancers called sarcomas which emerge in the body’s connective tissues, like muscles, fat, bones, blood vessels and joints. There are 50 different types of sarcomas. There...
What Is Osteosarcoma?
Osteosarcoma is the most common type of bone cancer in children and adolescents. The tumor often originates in the long bones of the body, and while osteosarcoma frequently starts in a particular bone, it can potentially move to other sites in the body, such as the lungs and other bones. This movement, known as metastasis, makes the disease more difficult to treat. “For patients that present with no evidence of metastatic or disseminated disease, the overall prognosis is about 70-75%,” said...

What is an Astrocytoma?
An astrocytoma is a brain tumor that begins in astrocytes—a type of glial cell that supports nerve cells in the brain. Astrocytomas can be benign or malignant and typically occur in the brainstem, cerebellum, cerebrum, hypothalamus or optic nerves. Tumors that start in glial cells are called gliomas and are named for the specific kind of glial cell in which they originate: astrocytes, oligodendrocytes or ependymocytes. Astrocytomas are the most common form of gliomas found in...
What is Langerhans Cell Histiocytosis (LCH)?
Langerhans cell histiocytosis (LCH) is a rare disorder in which the body produces an overabundance of Langerhans cells. These cells, which are also known as histiocytes, are a type of white blood cell that helps the immune system fight off infections. LCH causes too many of these cells to form, ultimately resulting in a buildup in the body. This accumulation of cells then damages organs, forms tumors, and otherwise disrupts normal tissue functions. According to the Histiocytosis Association,...
