    Radiation therapy

    Radiation therapy is used to fight many types of cancer.  Radiation targets rapidly dividing cells like cancer cells. Radiation prevents cell division and the replication of DNA (the genetic building blocks).

    Radiation therapy uses high-powered x-rays, particles, or radioactive seeds to kill cancer cells.

    Renal cell carcinoma

    The kidneys are responsible for removing wastes from the body, regulating electrolyte balance and blood pressure, and stimulating red blood cell production.

    Renal cell carcinoma is a type of kidney cancer that starts in the lining of very small tubes (tubules) in the kidney.

    The kidneys are responsible for removing wastes from the body, regulating electrolyte balance and blood pressure, and stimulating red blood cell production.

    Cancer of the renal pelvis or ureter is cancer that forms in the kidney’s pelvis or the tube (ureter) that carries urine from the kidney to the bladder.

    Retinoblastoma

    The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle tunic layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.

    Retinoblastoma is a rare, cancerous tumor of a part of the eye called the retina.

    Rhabdomyosarcoma

    Antigens are large molecules (usually proteins) on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, drugs, and foreign particles. The immune system recognizes antigens and produces antibodies that destroy substances containing antigens.

    Rhabdomyosarcoma is a cancerous (malignant) tumor of the muscles that are attached to the bones. This cancer mostly affects children.
