Myeloma is a form of blood cancer of the plasma cells in the bone marrow. This condition occurs when plasma cells become cancerous and produce tumours called plasmacytomas. This is also called multiple myeloma because a person may have more than one plasmacytomas. Plasma cells are the white blood cells formed in the bone marrow that create large amount of antibodies. Bone marrow is the spongy tissue found inside some of the bones and is where all blood cells are formed.

Lymphoma is one of the most common types of blood cancer which begins in cells of the lymph system. Lymphoma affects lymphocytes. Lymphocytes are a type of white blood cells which travel through the blood and lymphatic system to defend the body against foreign substances such as bacteria and viruses. In lymphoma, the growth of lymphocytes is out of control, they replicate faster than normal lymphocytes and live longer as they travel in the whole body through the blood and lymphatic system so lymphoma can spread in many parts of the body including spleen, bone marrow, lymph nodes, and other organs. Two main types of lymphoma are: Hodgkin lymphoma (HL): There are five types of Hodgkin Lymphoma. Non-Hodgkin lymphoma (NHL): There are over 90 types of NHL. Lymphoma is very much curable, but the outlook depends on the stage of lymphoma and its type.

Leukemia is a cancer of blood cells. Leukemia happens when there is a problem with the production of blood cells. In leukemia, abnormal blood cells are produced in the bone marrow. Leukemia usually affects white blood cells (WBC) or leukocytes. White blood cells are responsible for fighting infection however abnormal WBCs do not function in the same way as normal WBC. In leukemia, abnormal white blood cells continually divide and grow which eventually crowd out normal blood cells. Because of this, it becomes difficult for the body to fight infection, transport oxygen, and control bleeding. There are different types of leukemia: Acute leukemia: It develops rapidly, and a large number of leukemia cells accumulate very quickly in the blood and bone marrow. This kind of leukemia requires aggressive and fast treatment. Symptoms of acute leukemia are susceptibility to infections, easy bruising, tiredness, etc. Chronic leukemia: It develops slowly, so initially it may not cause specific symptoms. But if it is left untreated, it grows and shows signs like acute leukemia.

Bone marrow transplantation is a procedure wherein stem cells from bone marrow that produce various blood cells like red blood cells, white blood cells and platelets are injected into a recipient after a short course of chemotherapy called conditioning. These stem cells are also referred to as hematopoietic stem cells. Nowadays, hematopoietic stem cells may also be obtained from peripheral blood after treatment with certain growth factors or from umbilical cord. Thus , the term "Hematopoietic stem cell transplantation" is now preferred to "Bone marrow transplantation" to include these other sources of hematopoietic stem cells.

Out of all the blood-related disorders, anaemia is the most common and prevalent one, affecting more than half of the world population. As per a Global Nutrition report, India was placed at the bottom of the list with the maximum number of anaemic women in the world. More than about 51% of women in India belonging to the reproductive age are suffering from anaemia. So, the big question is what anaemia really is and how it affects people’s health. Anaemia refers to a condition where a person lacks enough red blood cells in his blood to carry adequate oxygen to various body tissues. When a person suffers from anaemia it can make him or she feel tired to perform even his everyday activities. Let us have a look at what causes anaemia and the Best Anaemia Treatment in Delhi.

Clinical Hematology or study of blood disorders is a highly specialised field related to diagnosis , evaluation treatment and treatment of blood disorders. Blood disorders range from simple iron deficiency anemia to highly complex and sometimes difficult to treat leukemia and lymphoma. Blood disorder may present as mild weakness , fatiguability , generalised lymphadenopathy , bleeding or fever. Whenever a haematological disorder is suspected, it is very important to consult your haematologist and plan treatment.

Chemotherapy is the administration of drugs that kill rapidly dividing cells such as leukemia or other cancer cells. Chemotherapy may be taken orally in pill or tablet form, or it may be delivered via a catheter or intravenous line directly into the bloodstream. Combination chemotherapy is usually given, which involves a combination of more than one drug. The drugs are given in cycles with rest periods in between. Sometimes, chemotherapy drugs for leukemia are delivered directly to the cerebrospinal fluid (known as intrathecal chemotherapy). Intrathecal chemotherapy is given in addition to other types of chemotherapy and can be used to treat leukemia in the brain or spinal cord or, in some cases, to prevent spread of leukemia to the brain and spinal cord. Side effects of chemotherapy depend on the particular drugs taken and the dosage or regimen. Some side effects from chemotherapy drugs include hair loss nausea, vomiting, mouth sores, loss of appetite, tiredness, easy bruising or bleeding, and an increased chance of infection due to the destruction of white blood cells. There are medications available to help manage the side effects of chemotherapy. Some adult men and women who receive chemotherapy sustain damage to the ovaries or testes, resulting in infertility. Most children who receive chemotherapy for leukemia will have normal fertility as adults, but depending on the drugs and dosages used, some may have infertility as adults.

Biological therapy is any treatment that uses living organisms, substances that come from living organisms, or synthetic versions of these substances to treat cancer. Biological therapies for various types of cancer can include antibodies, tumor vaccines, or cytokines (substances that are produced within the body to control the immune system). Monoclonal antibodies are antibodies that react against a specific target that are used in the treatment of many kinds of cancer. Interferons are cell signaling chemicals that have been used in the treatment of leukemia. Side effects of biological therapies tend to be less severe than those of chemotherapy and can include rash or swelling at the injection site for IV infusions of the therapeutic agents. Other side effects can include headache, muscle aches, fever, or tiredness.

Targeted therapies are drugs that interfere with one specific property or function of a cancer cell, rather than acting to kill all rapidly growing cells indiscriminately. This means there is less damage to normal cells with targeted therapy than with chemotherapy. Targeted therapies may cause the target cell to cease growing rather than to die, and they interfere with specific molecules that promote growth or spread of cancers. Targeted therapies are given in pill form or by injection. Side effects can include swelling, bloating, and sudden weight gain. Other side effects can include nausea, vomiting, diarrhea, muscle cramps, or rash.

Radiation therapy uses high energy radiation to target cancer cells. Radiation therapy may be used in the treatment of leukemia that has spread to the brain, or it may be used to target the spleen or other areas where leukemia cells have accumulated. Radiation therapy also causes side effects, but they are not likely to be permanent. Side effects depend on the location of the body that is irradiated. With any radiation therapy, the skin in the area being treated may become red, dry, and tender. Generalized tiredness is also common while undergoing radiation therapy.

In stem cell transplantation, high doses of chemotherapy and/or radiation are given to destroy leukemia cells along with normal bone marrow. Then, transplant stem cells are delivered by an intravenous infusion. The stem cells travel to the bone marrow and begin producing new blood cells. Stem cells may come from the patient or from a donor. Autologous stem cell transplantation refers to the situation in which the patient's own stem cells are removed and treated to destroy leukemia cells. They are then returned to the body after the bone marrow and leukemia cells have been destroyed. An allogeneic stem cells transplant refers to stem cells transplanted from a donor. These may be from a relative or an unrelated donor. A syngeneic stem cell transplant uses stem cells taken from a healthy identical twin of the patient. Stem cells may be removed (harvested) in different ways. Typically, they are taken from the blood. They can also be harvested from the bone marrow or from umbilical cord blood. Stem cell transplantation is done in a hospital, and it is necessary to remain in the hospital for several weeks. Risks of the procedure include infections and bleeding due to the depletion of normal blood cells. A risk of stem cell transplant with donor cells is known as graft-versus-host disease (GVHD). In GVHD, the donor white blood cells react against the patient's normal tissues. GVHD can be mild or very severe, and often affects the liver, skin, or digestive tract. GVHD can occur at any time after the transplant, even years later. Steroids or medications that suppress the immune response may be used to treat this complication.

Because many of the treatments for leukemia deplete normal blood cells, increasing the risk for bleeding and infection, supportive treatments may be needed to help prevent these complications of treatment. Supportive treatments may also be needed to help minimize and manage unpleasant side effects of medical or radiation therapy. Types of supportive and preventive treatments that can be used for patients undergoing treatment for leukemia include the following: Vaccines against the flu or pneumonia Blood or platelet transfusions Anti-nausea medications Antibiotics or antiviral medications to treat or prevent infections White blood cell growth factors to stimulate white blood cell production ( such as granulocyte-colony stimulating factor [G-CSF], made up of filgrastim [Neupogen] and pegfilgrastim [Neulasta] and granulocyte macrophage-colony stimulating growth factor [GM-CSF], made up of sargramostim [Leukine] ) Red cell growth factors to stimulate red blood cell production ( darbepoetin alfa [Aranesp] or epoetin alfa [Procrit] ) Intravenous injections of immunoglobulins to help fight infection
