What Is Chronic Lymphocytic Leukemia?
Leukemia and lymphoma are both forms of blood cancer. The main difference is that leukemia affects the blood and bone marrow, while. Excellent question. "Leukemia" basically means "white blood", or too many white blood cells in your peripheral blood. So it is the description of a clinical. The main difference between lymphomas and lymphocytic leukemias is the location of the cancer cells. In leukemia, they're found primarily in.
The cancer leukemia cells start in the bone marrow but then go into the blood. In CLL, the leukemia cells often build up slowly.
Many people don't have any symptoms for at least a few years. But over time, the cells grow and spread to other parts of the body, including the lymph nodes, liver, and spleen. Leukemia is cancer that starts in the blood-forming cells of the bone marrow. When one of these cells changes and becomes a leukemia cell, it no longer matures the way it should and grows out of control. Often, it divides to make new cells faster than normal. Leukemia cells also don't die when they should.
This allows them to build up in the bone marrow, crowding out normal cells.

At some point, leukemia cells leave the bone marrow and spill into the bloodstream. This increases the number of white blood cells in the blood.
Once in the blood, leukemia cells can spread to other organs, where they can prevent other cells in the body from functioning normally. Leukemia is different from other types of cancer that start in organs like the lungs, colon, or breast and then spread to the bone marrow.
Cancers that start elsewhere and then spread to the bone marrow are not leukemia. Knowing the exact type of leukemia helps doctors better predict each patient's outlook and select the best treatment. What is a chronic leukemia?
Leukemia vs. Lymphoma: What’s the Difference?
In chronic leukemia, the cells can mature partly and more are like normal white blood cells. These cells may look fairly normal, but they're not. They generally don't fight infection as well as normal white blood cells do. The leukemia cells survive longer than normal cells, and build up, crowding out normal cells in the bone marrow.
It can take a long time before chronic leukemias cause problems, and most people can live with them for many years. But chronic leukemias tend to be harder to cure than acute leukemias. What is a lymphocytic leukemia? Leukemia is myeloid or lymphocytic depending on which bone marrow cells the cancer starts in.
Lymphocytic leukemias also known as lymphoid or lymphoblastic leukemia start in the cells that become lymphocytes. Leukemia comes in many forms, but the key diagnosis is determined by whether the disease is acute or chronic.
Acute leukemias are fast-growing and may require aggressive treatments. Learn more about leukemia Lymphomas: These diseases affect the cells in the lymphatic system. In lymphomas, immune cells called lymphocytes grow out of control and collect in lymph nodes, the spleen, in other lymph tissues or in neighboring organs.
There are dozens of types of lymphoma, but the disease is largely categorized as Hodgkin or non-Hodgkin. Immunotherapy may be used to treat some cases of Hodgkin lymphoma. Other lymphoma treatments include chemotherapy and surgery to remove affected lymph nodes. Blood regulate the flow of oxygen and carbon dioxide in and out of the body, contains immune cells that fight infection, and delivers nutrients and hormones.
Red bone marrow produces new blood cells and platelets, which help regulate clotting.
Yellow bone marrow produces and stores fats that help build bone and cartilage. Lymph fluids carry immune cells throughout the body, deliver bacteria to lymph nodes to be filtered out of the circulatory system, and return excess proteins to the blood supply.

Patients with blood cancers often have symptoms common to all three forms of the disease: And some leukemias and lymphomas are so similarthey may be considered the same disease, but are named depending on whether they are found in the blood or in the lymph system. For instance, chronic lymphocytic leukemia and small lymphocytic lymphoma affect the same kind of cells—small lymphocytes—and are often considered different versions of the same disease.
A definitive diagnosis may require a bone marrow biopsy or a procedure called flow cytometryin which cancerous cells are analyzed with a laser. Topolsky says its critical to accurately diagnose not only the type of blood cancer, but which of the many sub-types the patient may have.
