Tumor Types (e.g., Leukemia, Neuroblastoma, Wilms Tumor)

Tumors are abnormal growths of cells in the body. **Leukemia** is a cancer of the blood and bone marrow, leading to an overproduction of immature white blood cells. **Neuroblastoma** is a cancer that primarily affects infants and young children, originating from nerve cells in the adrenal glands or spine. **Wilms Tumor** is a kidney cancer found mostly in children, typically affecting one kidney and often diagnosed before age five. Each type has distinct characteristics, affected areas, and treatment approaches, highlighting the diversity of cancer as a group of diseases.
