Leukemia

Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, however, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. There are different types of leukemia, including: -Acute lymphocytic leukemia. -Acute myeloid leukemia. -Chronic lymphocytic leukemia. -Chronic myeloid leukemia. Leukemia can develop quickly or slowly. Chronic leukemia grows slowly. In acute leukemia, the cells are very abnormal and their number increases rapidly. Adults can get either type; childen with leukemia most often have an acute type.Some leukemias can often be cured. Other types are hard to cure, but you can often control them. Treatments may include chemotherapy, radiation and stem cell transplantation. Even if symptoms disappear, you might need therapy to prevent a relapse.

Acute lymphoid leukemia

Acute lymphoblastic leukemia (ALL), also known as acute lymphocytic leukemia, is a subtype of acute leukemia, a cancer of the white blood cells. Somatically acquired mutations in several genes have been identified in ALL lymphoblasts, cells in the early stages of differentiation. Germline variation in certain genes may also predispose to susceptibility to ALL (Trevino et al., 2009). Genetic Heterogeneity of Acute Lymphoblastic Leukemia A susceptibility locus for acute lymphoblastic leukemia (ALL1) has been mapped to chromosome 10q21. See also ALL2 (613067), which has been mapped to chromosome 7p12.2; and ALL3 (615545), which is caused by mutation in the PAX5 gene (167414) on chromosome 9p. [from OMIM]

metaplastic cell transformation

The conversion of a cell from a normal phenotype, which undergoes a limited number of mitotic divisions, into an aberrant phenotype that is immortal and divides indefinitely. Transformed cells no longer retain cell-cycle checkpoints and may ultimately become malignant cancer cells via additional genetic mutations, or damaging environmental events. [from NCI]

Lymphatic Diseases

The lymphatic system is a network of tissues and organs. It is made up of: -Lymph - a fluid that contains white blood cells that defend against germs. -Lymph vessels - vessels that carry lymph throughout your body. They are different from blood vessels. -Lymph nodes - glands found throughout the lymph vessels. Along with your spleen, these nodes are where white blood cells fight infection. Your bone marrow and thymus produce the cells in lymph. They are part of the system, too. The lymphatic system clears away infection and keeps your body fluids in balance. If it's not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.  [from MedlinePlus]

Disorder of immune system

Your immune system is a complex network of cells, tissues, and organs that work together to defend against germs. It helps your body to recognize these foreign invaders. Then its job is to keep them out, or if it can't, to find and destroy them. If your immune system cannot do its job, the results can be serious. Disorders of the immune system include: -Allergy and asthma - immune responses to substances that are usually not harmful. -Immune deficiency diseases - disorders in which the immune system is missing one or more of its parts. -Autoimmune diseases - diseases causing your immune system to attack your own body's cells and tissues by mistake.
