All About Leukemia

A drug used to treat multiple sclerosis, Mitoxantrone an immunosuppressant has been found to heighten the risks of contracting leukemia as a side effect. The drug has been approved by the FDA and the side-effect is due to new research onto the interaction of the drug and the body’s response to it. High dosage of the drug has also been found to cause a lot of heart disease and can even cause irreversible heart damage according to the latest data from research.

Military personnel and people who work with radioactive compounds each and every day accept the fact that leukemia, often a risk of their jobs. New research in the use and administration of biphosphates to counteract the effects of radiation induced leukemia is proving promising to help reduce job related-risks for such people. People who work in space line astronauts of the many space agencies worldwide are also at risk of high exposure to radiation from space being out of the earth’s protective atmosphere which protects most of us here on the earth’s surface. Synthesized into chemopreventive medication they are proving effective in initial trials. They have been found to have the uncanny ability to remove uranium from the body which would be quite useful for people who handle and use radioactive munitions.

A newly discovered cancer-causing protein has been found to lessen the effectivity of the drug is now the target of researchers who are trying to block the said protein. This enhances the ability of Imatinib to treat leukemia making the targeting drug’s work easier and better. Proven to be effective against chronic myeloid leukemia (CML), the drug’s efficacy was unknowingly suppressed by some agent which led to the discovery of the cancer causing protein which blocked the drug lessening its effectivity.

Leukemia is cancer of the blood cells. In a healthy person, healthy blood cells are formed in the bone marrow in a normal, controlled manner. On the other hand, a person with leukemia produces large numbers of abnormal blood cells, usually white blood cells.

Chemotherapy is one of the treatment options in leukemia. There are many routes of administration in chemotherapy, oral (mouth), IV (intravenous), and intrathecal. The oral route is the least invasive but is absorbed by the bloodstream the slowest. When administered intravenously, drugs are absorbed rapidly. The problem with the IV route is that drugs do not reach the central nervous system due to the blood brain barrier. To answer this problem, doctors use another technique in giving chemotherapeutic drugs — the intrathecal route.

As with any other cancer treatments, it is important to consult your doctor to fully understand chemotherapy, including its side effects.

Researchers have recently discovered that a drug used to treat drug addiction, methadone has a very desirable effect on leukemia cells, killing them while not affecting the normal ones. This comes as a surprise for not only does it kill leukemia cells, it has also shown effectivity against forms of the disease that have previously been resistant to current drug therapies being used today. The methadone acts on the cancer cell’s by activating the mitochondrial pathway which activated specific enzymes within causing it to die off. This process, called pre-programmed death has also been observed with difficult cases that have not responded well to other treatment options. Animal studies are underway to determine the proper dosage and efficacy of using the drug as treatment for leukemia sufferers. They have proven that even low doses of the drug have had noticeable effects on the cancer cells killing them off making it one of the greatest breakthroughs in leukemia research.

People who live in areas where drilling for natural gas is underway should be aware that the current practice of the drilling industry releases dangerous levels of the cancerous chemical benzene into the water table. Benzene is a colorless, sweet smelling and highly toxic. Considered to be the highest cause of leukemia and some forms of cancer, it was even used as an odorant in the early 1900’s due to the sweet smell. Absorbed into the body in large enough quantities can be fatal and long term exposure has it absorbed into the cells causing DNA to mutate resulting in many forms of cancer. It is widely used as an industrial chemical and is vital for the manufacture of most plastics, it has been recently found in soft drinks and computer casings resulting in several checks by the USFDA and other agencies around the world.

Hairy Cell Leukemia is a chronic disease, which will never totally disappear once you acquire it. It is a rare condition often described as a slow growing cancer of the blood. The bone marrow is abnormally producing too much lymphocytes or B cells. This white blood cell is responsible for fighting infection. The surplus B cells looks hairy when you view it in the microscope, that’ how it got its name. The hairy part is actually the villi or the fine projections from the cell’s surface. As the abnormality increases, lesser healthy white blood cells, RBC and platelets are made. Men are said to be more prone to having this disease than women do. Its only limited to adults. Children and teenagers are not prone to this sickness. The cause of the disease is yet to be known and treatment can just lead to remission. It is not curable yet.

Leukemia has various treatment and stages. One of it is a combination of chemotherapy and radiation and medications are called induction. It is the process of abnormal cells to stop being made in the bone marrow and May last approximately one month and can be repeated if the goal is not achieved. Intensification is another stage; it is continued treatment even though leukemia may not be visible in blood test or bone marrow examination but possible that they are still present in the body. Maintenance is the stage that maintains leukemia-free bone marrow by continuing less intense chemotherapy several years. Regular visits to the doctor are required to detect recurrent disease and manage any side effects of the treatment. Relapse stage is when the bone marrow begins making abnormal cells again. It can occur during any of the stages of treatment, or years after treatment have ended.

All cancers begin in cells, which make up blood and other tissues. Normally, cells grow and divide to form new cells as the body needs them. When cells grow old, they die, and new cells take their place. But with Leukemia the new cells form when the body does not need them, and old cells do not die when they should. Leukemia is cancer that begins in blood cells. No one knows the exact causes of leukemia but there are certain factors that can put people at risk.

People who are at risk of having leukemia are those exposed to very high levels of radiation are much more likely to develop leukemia than others. Exposure to high levels of certain chemicals in the workplace can cause leukemia. Cancer patients treated with certain cancer-fighting drugs sometimes later develop leukemia. Down syndrome and certain other genetic diseases and some caused by abnormal chromosomes may increase the risk as well. Human T-cell leukemia virus-I (HTLV-I)—This virus causes a rare type of chronic lymphocytic leukemia known as human T-cell leukemia. However, leukemia does not appear to be contagious.
People with Myelodysplastic syndrome is at increased risk of developing acute myeloid leukemia.
Most people who have known risk factors do not get leukemia. On the other hand, many who do get the disease have none of these risk factors. People who think they may be at risk of leukemia or has a background of cancer in the family should discuss this concern with their doctor. The doctor may suggest ways to reduce the risk and can plan an appropriate schedule for checkups.

The term leukemia refers to cancers of the white blood cells, which are also referred to as leukocytes or WBCs. When a child has leukemia, large numbers of abnormal white blood cells are produced in the bone marrow. These abnormal white cells crowd the bone marrow and flood the bloodstream, but they cannot perform their proper role of protecting the body against disease because they are defective.

As leukemia progresses, the cancer interferes with the body’s production of other types of blood cells, including red blood cells and platelets. This results in anemia (low numbers of red cells) and bleeding problems, in addition to the increased risk of infection caused by white cell abnormalities.

As a group, leukemias account for about 25% of all childhood cancers and affect about 2,200 American young people each year.

Luckily, the chances for a cure are very good with leukemia. With treatment, most children with leukemia are free of the disease without it coming back. In general, leukemias are classified into acute (rapidly developing) and chronic (slowly developing) forms. In children, about 98% of leukemias are acute.
