In normal cells, hundreds of genes intricately control the process of cell division.
Cancers of the blood, such as leukemias, generally do not form solid tumors. In a healthy body, the trillions of cells it's made of grow and divide mutations can cause cells that should be replaced to survive instead of die, and new cells to form malignant tumors are cancerous and can invade other parts of the body. Many of the top cancer researchers are probing how to better utilize integrative treatments for cancer. But blood cancers, such as leukemia, don't generally grow as tumors;
