Chronic Lymphocytic Leukemia and the Railroad

CLL (chronic lymphocytic Leukemia) is a type of cancer which affects both bone marrow as well as blood. It is a cancer that grows slowly that can cause a low blood platelet count (thrombocytopenia), swelling of lymph nodes or growths of the liver and/or spleen.

Research has linked exposure to benzene, a chemical that is found in diesel fumes/exhausts and used by railroad workers on trains, with an increased risk of CLL. CLL has also been associated with exposure to certain pesticides.

Benzene

Benzene can be harmful to humans and may cause cancer in those who are exposed to the chemical for a long period of time. Benzene can be found in industrial solvents, gasoline, like glue, paint and varnish. It can also be used to create other chemicals such as phenol, aniline, and dodecylbenzene, which are used for dyes as well as degreasing the metal. The most serious complication of exposure to benzene are blood cancers and lymph nodes, specifically leukemia. It is known that benzene damages cells in the bone marrow. This damage could lead to chronic myeloid (CML). The disease begins in the bones and develops into blood. It may also progress into blood cancers of other types such as non-Hodgkin's lupus or myelodysplastic Syndrome.

People who are regularly exposed to benzene while at work are at a higher chance of developing these illnesses. Researchers analyzed 15 studies as part of the 2010 Environmental Health study and found that workers who were regularly exposed at work were exposed to a 40% higher risk of leukemia.

Exposure to benzene poses dangers to any person, but it's particularly dangerous for those working in oil refineries, rubber factories gas stations, shoe manufacturing plants. Other professions that are affected include mechanics, truck drivers and Railroad Multiple Myeloma employees. In addition to its effects on the bone marrow cause eye and skin irritation. It can be breathed in and consumed by workers.

Butadiene

It is beyond dispute that Railroad Emphysema workers are exposed many dangerous chemicals, such as benzene and butadiene, on a regular basis. These chemicals are found in the diesel exhaust which is emitted by trains on tracks. Exposure to harmful chemicals can cause serious health problems for railroad employees and their family members. The presence of these substances in diesel exhaust has been associated with CLL, as well as other cancers and leukemias.

Butadiene is a synthetic chemical that is used to create synthetic rubber and other plastics. It is also an ingredient in some fungicides, and latex adhesives. 1,3-Butadiene is also a byproduct from extraction of oil and gas as well as processing of petroleum. It is released into the atmosphere from industrial workplaces as well as bush and forest fires.

Exposure to BD can cause irritation of the nose, eyes throat and the lungs. It can also cause drowsiness, or blurred vision. In chronic exposure, it can cause kidney and liver damage and also anemia. It is a recognized cancer-causing agent and has a moderate acute and a slight chronic toxicity to aquatic life.

Butadiene will evaporate quickly if released into the air. Its half-life is around one day in the air. If exposed to sunlight, it deteriorates quickly. The most commonly used method of human exposure to butadiene is through inhalation.

Pesticides

Many railroad workers were exposed to benzene butadiene and pesticides on a regular basis. These chemicals are found in diesel fumes/exhaust that Railroad Multiple Myeloma workers breathed through their noses as well as mouths. Railroad Interstitial Lung Disease workers also employed insecticides and herbicides on railway tracks, Railroad Multiple Myeloma at railway crossings, and within the rail yards to control the growth of vegetation. Certain chemicals have been linked to cancer, including paraquat and 2,4D.

Other factors that increase the risk of developing chronic leukemia include age (this cancer is most common in older people) and a family background of bone-marrow cancers and blood, including other types lymphoma. A small number people with chronic leukemia will develop an aggressive form of the disease, which is known as diffuse large B cell lymphoma. This is associated with other health issues, such as hemolyticanemia that is autoimmune and a low platelet count.

The National Cancer Institute (NCI) suggests that patients suffering from chronic lymphocytic tumors discuss their work history with a doctor. This is particularly important if the worker was exposed to carcinogens such as butadiene or benzene while in the course of their work. This PDQ cancer information summary was written by NCI staff and is based upon scientific evidence from research in people. It's meant to assist patients, their families, and caregivers make informed decisions about their care.

Genetics

The chance of having chronic lymphocytic cancer is determined by a variety of factors. It's more prevalent in older adults, specifically those in their 70s. People who have an ancestor with the disease are also at a higher risk. Exposure to certain chemicals, such as benzene, can also increase the risk. People who worked in the railroad industry are at a higher risk of developing CLL and other blood cancers.

In certain instances, B cells that produce antibodies change and transform into cancerous cells. They then begin to grow at a higher rate than healthy cells. The cancerous cells could block healthy cells from the bone marrow and Railroad Multiple Myeloma blood and cause other health problems.

If the cancerous cells are CLL that is Ig-unmutated and they are growing at a slower rate than CLL with Ig mutations. They can cause a range of symptoms, depending on the extent to which they expand and the places they are spread.

The symptoms include symptoms include anemia (low levels of red blood cells), the thrombocytopenia (low number of platelets), and chronic infections. The slow-growing version of the disease can also lead to large nodes that could cause problems for nearby organs.

Researchers are investigating whether a genetic component could be linked to the risk of developing chronic leukemia. Participants in genetic studies must provide DNA or saliva sample, as well as medical and family histories.
