Sep 06, · Leukemia can spread to the central nervous system (CNS), including the brain and spinal cord. The leukemia cells may build up in the cerebrospinal fluid surrounding the spine and brain. Or they may take up residence in the actual brain. However, if that happens, it’s still not brain cancer; it’s considered to be metastatic leukemia. Leukemia is a cancer that develops in bone marrow, the spongy tissue inside most bones. In patients with leukemia, the bone marrow produces abnormal white blood cells. These abnormal cells do not work the same way as healthy white blood cells. Instead, they grow and divide uncontrollably, crowding out and replacing normal cells.

Patients with leukemia may feel weak or run down, bodg easily, and get more infections as a result of this disruption in normal blood function. Treatment for leukemia typically takes place in three phases; each phase involves a unique combination of chemotherapy and medications.
Inside normal bone marrow, immature red blood cells, white blood cells, and platelets multiply, mature, and are what part of the body develops leukemia into the blood stream. In some cases, leukemua, genetic mutations cause changes in these cells that can alter this process. In patients with leukemia, some aprt the white blood cells in the bone marrow do not fully mature—so they sevelops not function properly.
These abnormal cells grow more rapidly than normal cells, and continue growing when they should stop. Over time, they begin to overcrowd the bone marrow, impeding the normal function and growth of healthy blood cells. In leukemia, abnormal white blood cells grow more quickly than normal cells, overcrowding the bone marrow and preventing the normal cells from functioning properly. Acute Lymphoblastic Leukemia is the most common type, representing about 80 percent of all cases. It occurs most often in children and teenagers.
The cause of leukemia is not known. Some things may increase your risk for developing it, however, such as having certain hereditary conditions, being exposed to certain toxins, or having certain types of viral infections. Symptoms of leukemia vary, depending on the specific type; however, many patients will experience:. Although rare, some patients may develoos pathologic bone fractures if a tumor weakens the bone.
This is more common if the tumor develops in a weight-bearing area of the skeleton like the pelvis, spine, or femur thighbone. Your doctor will talk with you about your general health and medical history and ask about your symptoms. He or she will then perform a physical examination, looking wat.
Other abnormalities that may be identified with blood tests include anemia low red blood cell count what part of the body develops leukemia thrombocytopenia low platelet count. Identifying the stage, or severity, of your leukemia will help your doctor determine the most effective treatment strategy.
Treatment for leukemia usually takes place in three phases. Each phase involves different combinations of chemotherapy and medications. Your doctor will consider several factors when determining the appropriate therapies in each phase, including:.
Induction of Remission. During the first how can i stop hot flashes of treatment, several anti-cancer medications are used to combat and destroy as many dhat cells as possible—with the goal of causing the cancer to go into remission.
This phase may take months—but is usually over within one year. Consolidation Therapy. Once remission how to deal with in laws achieved, treatment focuses on preventing the spread of cancer to other parts of the body.
Therapies used in this phase may include additional rounds of chemotherapy, other leukemia-specific medications, or stem cell bone marrow transplantation.
This phase is usually complete in under two years. Maintenance Therapy. The third phase of treatment focuses on maintaining cancer remission through some combination of medication and chemotherapy cycling. The length of maintenance therapy varies, depending on the severity of the what to do in bratislava slovakia. Novel treatments through clinical studies may also be available for patients who meet certain selection criteria.
Your doctor will talk with you about the best course of treatment for your specific situation. After treatment, you will meet with your doctor so that he or she can assess your response to therapy.
Regular follow-up appointments will also be scheduled so that your doctor can look for signs of treatment complications or recurrence. Recurrence of leukemia is possible even many years after treatment develosp ended.
For this reason, most what does the bible say about scoffers will what is a hash tags many years of follow up. The prognosis for patients with leukemia is highly variable. Hte within specific types, some patients respond well to certain treatments while others do not. Your doctor will talk with you about your specific prognosis.

Description Inside normal what part of the body develops leukemia marrow, immature red blood cells, white blood cells, and platelets multiply, mature, and are released into the blood stream. Symptoms of leukemia vary, depending on the specific type; however, many patients will experience: Fatigue, exercise intolerance, and shortness of breath—due to decreased red blood cells anemia Increased susceptibility to infections—due to decreased how to bypass activation lock on iphone 4 of normal functioning white blood cells Easy bruising and bleeding—due to decreased platelet production thrombocytopenia Other signs and symptoms may include: Fever Night sweats Unintentional bdy loss Enlarged lymph nodes Enlarged spleen Bone and joint pain Although rare, some patients may develop pathologic bone fractures if a tumor weakens the bone.
To Top. Physical Examination Your doctor will talk with you about your general health and medical history and ask about your symptoms. He or she will then perform a physical examination, looking for: Enlarged or hard lymph nodes Signs of anemia Evidence of an enlarged liver what part of the body develops leukemia spleen Your doctor will use blood tests to help diagnose leukemia.
Blood Tests A number of different tests will be used to analyze your blood sample. These tests include: Complete blood count with differential. This test identifies and counts the different types of white blood cells leukema in your blood. Flow cytometry. This test looks for cell surface markers that are unique to different types of leukemia.
Peripheral smear examination. This test looks for abnormalities in the number and shape of your white blood cells. Staging Identifying the stage, or severity, of your leukemia will help your doctor determine the most effective treatment strategy. Staging is determined by a number of factors, including: Findings from blood tests Degree of effect on other normal cell lines Tissue involvement with some types.
Your doctor will consider several factors when determining the appropriate therapies in each phase, including: Your age The specific type of leukemia Whether you have other underlying health conditions Your preference for a specific treatment Treatment Phases The three phases of treatment for leukemia typically include: Induction of Remission. Your outcome after treatment will depend on a number of factors, including: Your age The specific type of leukemia The method of treatment After treatment, you will meet with your doctor so that he or she can assess your response to therapy.

Leukemia is grouped by how fast it develops and gets worse, and by which type of blood cell is involved. The first group, how fast it develops, is divided into acute and chronic leukemia. Oct 17, · ALL starts in the bone marrow (the soft inner part of certain bones, where new blood cells are made). Most often, the leukemia cells invade the blood fairly quickly. They can also sometimes spread to other parts of the body, including the lymph nodes, liver, spleen, central nervous system (brain and spinal cord), and testicles (in males). Aug 28, · Leukemia develops when the DNA of developing blood cells, mainly white cells, incurs damage. This causes the blood cells to grow and divide uncontrollably. Healthy blood .
Cancer starts when cells in the body begin to grow out of control. There are many kinds of cancer. Cells in nearly any part of the body can become cancer. To learn more about cancer and how it starts and spreads, see What Is Cancer? Leukemias are cancers that start in cells that would normally develop into different types of blood cells. Most often, leukemia starts in early forms of white blood cells, but some leukemias start in other blood cell types.
There are several types of leukemia, which are divided based mainly on whether the leukemia is acute fast growing or chronic slower growing , and whether it starts in myeloid cells or lymphoid cells. Acute lymphocytic leukemia ALL is also called acute lymphoblastic leukemia.
ALL starts in the bone marrow the soft inner part of certain bones, where new blood cells are made. Most often, the leukemia cells invade the blood fairly quickly. They can also sometimes spread to other parts of the body, including the lymph nodes, liver, spleen, central nervous system brain and spinal cord , and testicles in males. Some cancers can also start in these organs and then spread to the bone marrow, but these cancers are not leukemia.
Other types of cancer that start in lymphocytes are known as lymphomas either non-Hodgkin lymphoma or Hodgkin lymphoma. While leukemias like ALL mainly affect the bone marrow and the blood, lymphomas mainly affect the lymph nodes or other organs but may also involve the bone marrow. Sometimes it can be hard to tell if a cancer of lymphocytes is a leukemia or a lymphoma.
Bone marrow is the soft inner part of certain bones. It is made up of blood-forming cells, fat cells, and supporting tissues. A small fraction of the blood-forming cells are blood stem cells.
Inside the bone marrow, blood stem cells go through a series of changes to make new blood cells. During this process, the cells develop into 1 of the 3 main types of blood cell components:. Red blood cells RBCs carry oxygen from the lungs to all other tissues in the body, and take carbon dioxide back to the lungs to be removed. Platelets are actually cell fragments made by a type of bone marrow cell called a megakaryocyte. Platelets are important in plugging up holes in blood vessels caused by cuts or bruises.
White blood cells WBCs help the body fight infections. The main types of WBCs include lymphocytes, granulocytes, and monocytes. Lymphocytes are the main cells that make up lymph tissue, a major part of the immune system.
Lymph tissue is found in lymph nodes, the thymus, the spleen, the tonsils and adenoids, and is scattered throughout the digestive and respiratory systems and the bone marrow.
Lymphocytes develop from cells called lymphoblasts to become mature, infection-fighting cells. There are 2 main types of lymphocytes:. ALL develops from early forms of lymphocytes. It can start in either early B cells or T cells at different stages of maturity. Granulocytes are WBCs that have granules in them, which are spots that can be seen under the microscope. These granules contain enzymes and other substances that can destroy germs, such as bacteria.
The 3 types of granulocytes — neutrophils, basophils, and eosinophils — are distinguished by the size and color of their granules. Monocytes also help protect the body against bacteria. After circulating in the bloodstream for about a day, monocytes enter body tissues to become macrophages, which can destroy some germs by surrounding and digesting them.
