Neuroblastoma Disease

神經母細胞瘤是一種類型的癌症，在某些類型的神經組織的形成。

Neuroblastoma (NB) is a type of cancer that forms in certain types of nerve tissue. It most frequently starts from one of the adrenal glands, but can also develop in the neck, chest, abdomen, or spine. Symptoms may include bone pain, a lump in the abdomen, neck, or chest, or a painless bluish lump under the skin. Occasionally neuroblastoma may be due to a mutation inherited from a person's parents. Environmental factors have not been found to be involved. Diagnosis is based on a tissue biopsy. Occasionally it may be found in a baby by ultrasound during pregnancy. At diagnosis the cancer has usually already spread. The cancer is divided into low, intermediate, and high risk groups based on a child's age, cancer stage, and what the cancer looks like.
