- Leukemia - a blood cancer that begin in the bone marrow and affects leukocyte development (white blood cell blasts). The most common type of childhood leukemia is ALL (acute lymphoblastic leukemia), followed by AML (acute myloid leukemia). There are also chronic and infectious leukemias, which occur mainly in adults.
- Lymphoma - a cancer of the B or T lymphocytes, a crucial part of the immune system. It affects the lymph system as well. There are over a dozen kinds of lymphoma, with the most common kinds being Hodgkins and Pre-T Cell Lymphoma.
- Sarcoma - a soft or connective tissue tumor that can occur in various tissue types, such as bone (Osteosarcoma, Ewing's Sarcoma), cartilage/connective tissue (chondrosarcoma, fibrosarcoma, neurofibrosarcoma), skeletal muscles (rhabdomyosarcoma), or smooth muscle (leiomyosarcoma). While these cancers are rare, 15% are diagnosed in children.
- Wilm's Tumor - a tumor of the kidney, which occurs only in children.
