They will even copy articles for you. However, they do charge for the searches. This article was written to give patients a general overview of this class of diseases. The leukemias are cancers of the blood forming cells. Acute leukemia involves the most primitive of these types of cells.
Clonal cells share two common features that lead to the symptoms of leukemia.
The cells divide without control and fail to respond to the signals that tell them to stop. These cells have a longer life than normal cells and gradually accumulate in the bone marrow. This uncontrolled production of long lived cells leads to the replacement of the normal cells in the bone marrow with leukemic clones. Since the space is limited in the marrow, the normal cells are crowded out by these clones. All the normal blood forming elements are eventually affected if the leukemia goes unchecked.
