What I learned from other cancer brochure

Evelyn's cancer brochure is about neuroblastoma,a kind of brain cancer.  What I learned from this brochure is this typical cancer is a childhood cancer that spreads very rapidly. Surprisingly, the tumor may vanish on its own. Other times, the tumor may mature and turn into a beign tumor which can be surgically removed. The symptoms of the disease has no difference with flu which are fever, pain, or diarrhea. Neuroblastomas usually starts next to the spinal cord and it is possible to spread to the skull, pelvis, face, legs, skin, etc. Until today, the cause of neuroblastoma is unknown. It hits about 1 outo of 100,000 children and it is more common in boys.
