What is Atypical Teratoid/Rhabdoid Tumor (AT/RT)?
Atypical Teratoid/Rhabdoid Tumor (AT/RT) is a rare and fast-growing tumor that typically originates in the brain and spinal cord. These...
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...
What is Acute Lymphoblastic Leukemia (ALL)?
Acute lymphoblastic leukemia, also called acute lymphocytic leukemia, or ALL for short, is a type of blood cancer that causes bone marrow...
What is Wilms Tumor?
Wilms tumor is a type of kidney cancer that primarily develops in children around the ages of three and four. It’s the most common type of...
What is Retinoblastoma?
In simple terms, retinoblastoma is an eye cancer that develops in the immature cells of the retina. Though it is rare—with approximately...
What is Brain Tissue Donation?
When your child is first diagnosed with brain cancer, you may be asked if you want to donate your child’s tumor tissue. A brain tissue donation is a very personal decision to make, especially at a time when you are confronted with so many decisions and questions. This informative video, “The Journey of Donated Tissue” by our friends at the Swifty Foundation will answer many of the questions you might have. Rally is very supportive of brain tissue donation, and wants to help spread awareness of...
What is an MRI?
MRI stands for Magnetic Resonance Imaging. Having an MRI does not hurt, and it is safe – no radioactivity is present. It may take up to one hour, or, if your child needs an anesthetic, most of the day. An MRI scan provides diagnostic information not available when using plain X-rays, ultrasounds, or CT scans. Using a large magnet, radio waves and a computer, an MRI scanner creates very clear and detailed images of organs and tissues in the body. During the MRI, your child will need to lie very...
What is a CT Scan?
A CT (or CAT) scan is a diagnostic medical imaging procedure that creates three-dimensional images of internal organs, soft tissues, blood vessels and bones. CT stands for Computed Tomography. It provides a more detailed image than a traditional X-ray. Most CT scans take a few seconds, while some may take more than 10 minutes. The CT scanner looks like a giant donut with a sliding bed inside, and your child needs to lie very still during the procedure. It’s important to wear comfortable,...
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,...
What is Lymphoma?
Lymphoma is a cancer of the body’s lymphatic (lymph) system which is essential to the immune system. The lymphatic system is made up of a type of white blood cells also known as lymphocytes which flow throughout the whole body. These lymphocytes fight infections throughout the body, so when cancerous cells begin to grow they can quickly spread through the entire lymph system. This then makes it difficult for the immune system to work properly. Early symptoms of lymphomas usually begin with a...
