Some children may be very ill, and some children may not have any symptoms at all. Types of Solid Tumors 1.

Bone marrow transplant (BMT) also called as hematopoietic stem cell transplant (HSCT) is the procedure that is used to replace the unhealthy bone marrow with new and healthy bone marrow. Bone marrow is the soft, fatty tissue inside the bones that is responsible for the production of blood cells. There are several medical conditions due to which the bone marrow become dysfunctional and therefore needs to be replaced.
