Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones. Impact factor can be calculated as average number of citation divided by recent cited articles published in 2 years. Most blood cancers, also called hematologic cancers, start in the bone marrow, which is where blood is produced. Blood cancers occur when abnormal blood cells start growing out of control, interrupting the function of normal blood cells, which fight off infection and produce new blood cells. Treatment for blood cancer depends on the type of cancer, your age, how fast the cancer is progressing, where the cancer has spread and other factors. Some common blood cancer treatments include: Stem cell transplantation: A stem cell transplant infuses healthy blood-forming stem cells into the body. Stem cells may be collected from the bone marrow, circulating blood and umbilical cord blood. Chemotherapy: Chemotherapy uses anticancer drugs to interfere with and stop the growth of cancer cells in the body. Chemotherapy for blood cancer sometimes involves giving several drugs together in a set regimen. This treatment may also be given before a stem cell transplant. Radiation therapy: Radiation therapy may be used to destroy cancer cells or to relieve pain or discomfort. It may also be given before a stem cell transplant.

Many types exist such as acute lymphoblastic leukaemia, acute myeloid leukaemia and chronic lymphocytic leukaemia. Many patients with slow-growing types of leukaemia don't have symptoms. Rapidly growing types of leukaemia may cause symptoms that include fatigue, weight loss, frequent infections and easy bleeding or bruising. Treatment is highly variable. For slow-growing leukaemias, treatment may include monitoring. For aggressive leukaemias, treatment includes chemotherapy that's sometimes followed by radiation and stem-cell transplant. Blood cells are made inside your bone marrow, and that’s where leukemia starts. It causes your body to make white blood cells that grow out of control and live longer than they’re supposed to. And unlike normal white blood cells, they don’t help your body fight infection. There are many different forms of leukemia. Some get worse quickly (acute). You’ll probably feel very sick very suddenly, like you’ve come down with the flu. Other forms can take years to cause symptoms (chronic). Your first clue may be abnormal results on a routine blood test.
