Blood cancers begin in the bone marrow or immune system and affect how blood cells grow and function. These cancers often develop silently, with symptoms that may go unnoticed until the disease is advanced. While some risk factors are genetic or unknown, certain environmental and workplace exposures increase the risk of developing blood cancers.

Blood Cancer Today reports that approximately 66,890 individuals are expected to be diagnosed with leukemia, leading to around 23,540 deaths in 2025. These increases are from various reasons, including chemicals like benzene and PFAS, household products, and even drinking water. 

This article shares facts that matter to help patients and families understand the risks and recognize early signs.

Common Sources of Toxic Exposure

Toxic exposure happens more often than many people realize. It can occur at work, at home, or even in the surrounding community. Let’s understand some common sources that increase the risk of blood cancers.

Workplace Exposure

Many people are exposed to dangerous chemicals while on the job. Industries such as oil refining, chemical manufacturing, dry cleaning, and firefighting are known for high exposure risks. Benzene is one of the most harmful chemicals found in these settings. It is used in the production of plastics, rubbers, dyes, and other materials. 

A study in PubMed showed that workers exposed to more than 550 mg/m³ of benzene had a higher risk of developing leukemia. Also, alcohol use may intensify the risk of leukemia in those exposed to benzene. Exposures to these chemicals are often short-lived, yet they still carry long-term consequences. The risk builds over the years, especially without proper safety measures.

Home and Daily Environment

Toxic exposure is not limited to the workplace. It can also happen inside the home. One major source is the use of gas stoves. A study published in ScienceDirect highlights that benzene exposure increased sharply in homes with medium to high gas stove usage.

The kitchen, living room, and especially bedroom were found to have the highest benzene concentrations after gas stove use. Children’s cancer risk from gas stove benzene exposure was 1.85 times higher than adults. 

Even household dust can be a threat. The University of California, Berkeley, highlights a study that analyzes PFAS chemicals found in household dust. They found that children who were exposed to PFAS chemicals in dust had a 1.6 times higher chance of developing leukemia. This shows that exposure can also come from the carpet under your feet or the air in your kitchen.

Community and Environmental Risks

Some communities face higher risks because of nearby factories, military sites, or outdated water systems. In the U.S., military sites like Camp Lejeune and Little Rock Air Force Base have become examples of community-wide toxic sites. People living in these areas have shown clusters of blood cancer cases connected to PFAS and industrial pollutants in local water systems.

In response, affected individuals began filing lawsuits against PFAS manufacturers. Their claims centered on the lack of warning about the health dangers of prolonged PFAS exposure. For people facing similar situations, especially those in Arkansas, speaking with a Little Rock personal injury lawyer may be an important step. 

Keith Law Group says a qualified attorney can help assess whether long-term toxic exposure may be linked to a cancer diagnosis. They can also explain the legal options available to hold companies accountable for the harm caused. 

Who Is at Higher Risk of Blood Cancers

Some people face a greater risk of blood cancers from toxic exposure based on where they live, work, or how they grow up. These risks are not evenly shared. People working in industrial jobs are one of the highest-risk groups. These include workers in oil refineries, manufacturing plants, dry cleaning services, and chemical warehouses. 

Those who serve in the military, especially on bases with known contamination, are also at high risk. For example, service members stationed at Camp Lejeune between the 1950s and 1980s were exposed to drinking water filled with toxic chemicals. Decades later, many of them have developed leukemia and other cancers linked to those exposures.

Furthermore, pregnant women and children are especially sensitive to chemical exposure. Their bodies are still growing and are more likely to absorb toxins quickly. Pediatric Cancer Research Foundation highlights that PFAS exposure during pregnancy may increase the risk of acute lymphoblastic leukemia (ALL) in children. Mothers with the highest levels of a PFAS called PFOS had the highest chance of having a child with ALL.

People who rely on private wells for drinking water also face added risks. These wells are often unregulated and can be contaminated without warning. In areas where PFAS has leaked into the groundwater, families may drink tainted water for years without knowing. Over time, these exposures increase the risk of blood cancer, especially for older adults and people with other health conditions.

FAQs

What is the leading cause of blood cancer?

The leading cause of blood cancer is genetic mutations in blood-forming cells. This can occur naturally or be triggered by environmental factors such as radiation, toxic chemical exposure (like benzene), or certain infections. These mutations disrupt normal blood cell production and lead to uncontrolled cell growth.

What is the deadliest cancer?

Lung cancer is the deadliest cancer worldwide, causing the highest number of cancer-related deaths each year. Its aggressive nature, late-stage diagnosis, and strong links to smoking and environmental pollutants contribute to its high mortality rate.

Is blood cancer curable?

Some types of blood cancer are curable, especially when detected early and treated effectively with chemotherapy, targeted therapy, or stem cell transplants. However, outcomes vary depending on the specific type, stage, and patient factors, with some forms remaining difficult to cure completely.

Blood cancers caused by toxic exposure are not random; they are often the result of long-term contact with chemicals. Many of these exposures happen without warning, leaving people to deal with serious health issues they didn’t see coming.

Patients and families deserve honest, clear information about the risks in their environments. They also need stronger protections to reduce future harm and the chance to seek accountability when those protections fail. 

If your illness is tied to exposure that could have been prevented, you have every right to ask questions and seek legal support. Acting early can make a real difference. It can lead to better treatment options, fair compensation, and peace of mind for what lies ahead.
