Leukemia is a cancer of the blood, bone marrow and lymphatic system. In leukemia, the bone marrow produces an abnormally large amount of white blood cells and the white blood cells do not function properly. Symptoms of leukemia include fatigue,...
Bone marrow is the spongy tissue found in the center of bones. It is responsible for making red blood cells, white blood cells and platelets. Marrow is mainly found in flat bones such as the skull, ribs, vertebrae, shoulder blades, hip bones,...
The bone marrow is a tissue inside flat, irregular-shaped bones and the long bones. There is yellow bone marrow and red bone marrow. Yellow, only found in the long bones of adults, contains fat cells. Red bone marrow contains stem cells that give...
Your body uses vitamin B12 to manufacture red blood cells and maintain healthy nerve tissue. A B12 deficiency may take up to five years to manifest. Symptoms of this type of deficiency include fatigue, weakness, pale skin, heart palpitations and...
Bone marrow contains red blood cells, white blood cells and platelets. To help diagnose blood and bone marrow diseases as well as infections, a physician may perform a bone marrow aspiration or biopsy. A large needle is inserted into the bone, and...
Bone marrow aspiration is often one of the first aspects of a bone marrow test. With a bone marrow aspiration, a doctor uses a syringe with a large, hollow needle to extract some of the liquid bone marrow from the body. The bone marrow is often...
Adult men have the diagnosis of anemia if their hemoglobin level is below 13.5g/dL, and women are anemic if their level is below 12g/dL, according to Charles Linker, M.D., clinical professor of medicine at the University of California, in "Current...
There are approximately 8,000 new cases of Hodgkin's disease every year, according to Carol Portlock, M.D., attending physician of the Lymphoma Service at the Memorial Sloan-Kettering Cancer Center in "The Merck Manual for Healthcare...
There are three types of blood cancers: leukemia, lymphoma and myeloma. According to the Leukemia and Lymphoma Society, an estimated 139,860 people in the United States were diagnosed with leukemia, lymphoma or myeloma in 2009. Every 10 minutes...
The bone marrow, which is the spongy material inside of bones, is responsible for making many of the cells that circulate in the blood. The bone marrow contains special cells, called blood stem cells, which are able to produce these mature blood...
As medicine and science begin to better embrace the basic vitamins and minerals our bodies need for good health, there are often reports about these nutritional supplements being a treatment or cure for new conditions and diseases. Vitamin B12 has...
Ganglioneuroblastoma is often identified when a parent or child recognizes a hard mass in the child's abdomen, though the cancerous tumors are capable of growing elsewhere in the body. When they are located on the face or head, there will usually...
Leukemia is a cancer of the blood or bone marrow. The main characteristic of leukemia is the production of too many leukocytes, or white blood cells. Chronic myelogenous leukemia (CML) is one of four types of leukemia. While all forms involve the...
AML is a kind of leukemia that is also known as acute myeloid leukemia, acute myelogenous leukemia, acute granulocytic leukemia and acute myelocytic leukemia. It starts in the bone marrow and the cells that turn into various types of blood cells,...
Lymphoma is the third most common childhood cancer, according to the University of California-San Francisco (UCSF) Children's Hospital. In non-Hodgkin's lymphoma, tumors develop from white blood cells in the lymphatic system, a network of vessels...
Your bone marrow makes immature cells called stem cells; these develop into a myeloid stem cell or a lymphoid stem cell. The myeloid cells develop into red blood cells, myeloblasts and platelets. These myeloblasts turn into white blood cells that...
Experts classify non-Hodgkins lymphoma cells by two different types of cell reactions. B cells are the cells responsible for 90 percent of non-Hodgkins lymphoma cases. Inside your body, the B cells undergo changes within their lifecycles and can...
There are two main categories of lymphomas; Hodgkin's lymphoma and non-Hodgkin's lymphomas. Non-Hodgkin's lymphoma, or NHL, has many subtypes, but it is a type of cancer that starts in cells called lymphocytes that are involved in the immune...
Bone marrow produces immature blood cells that develop into white cells called lymphoblasts or lymphocytes. When your body produces too many of these lymphoblasts, these are called leukemic cells. You develop acute lymphoblastic leukemia when you...
Hodgkin's Lymphoma is cancer of the lymph system. Symptoms may vary depending on how far the disease has spread. At first the symptoms may be vague and feel like the flu. A person may experience fatigue, fever and weight loss. Itching and night...
Retinoblastoma is a childhood cancer that occurs in the eyes of young children. Sometimes one eye is affected (unilateral retinoblastoma) and sometimes both eyes are affected (bilateral retinoblastoma). This rare eye cancer, which originates in...
Hodgkin's disease is cancer of the lymph tissue found in the spleen, lymph nodes and bone marrow. The lymphatic system is part of the immune system that fights infection. MD Anderson Cancer Center states that since lymph nodes are located in...
Hairy cell leukemia is a type of cancer which originates in the bone marrow and affects a type of white blood cell called a B cell. The cancerous cells appear hairy when viewed under a microscope. The cause of hairy cell leukemia is unknown, but...
The red blood cells are critical for transporting oxygen throughout the body. Anemia describes any condition in which there is reduced red blood cell numbers, which can cause pallor and chronic fatigue. Macrocytic anemia is unique among types of...
Blood cancer, also called hematologic cancer, can begin in the bone marrow, lymph nodes or blood itself and involves any of the many types of blood cells that circulate throughout the body. Diagnosis of blood cancer may be easy to make, but...
Bone marrow, the spongy inner part of bones, produces platelets, red blood cells and white blood cells. Bone-marrow testing assesses the health of a patient's bone marrow. Sampling of bone marrow requires either a biopsy or aspiration procedure....
Multiple myeloma is a cancer of plasma cells involving primarily the bone marrow, which releases a distinctive protein into the blood used for diagnosis. The disease usually occurs in older adults, with approximately 16,000 new cases diagnosed...
The blood is composed of cellular and liquid portions. Red blood cells, also known as erythrocytes, carry oxygen. A condition of lower red blood cell counts is called anemia, a condition that can cause weakness, fatigue and pale skin. Anemia is...
The bone marrow is the center of production of white blood cells, red blood cells and platelets. WBCs fight infections, RBCs carry oxygen throughout the body and platelets cause the blood to clot to prevent bleeding. Healthy bone marrow...
