While chronic stress isn't proven to cause leukemia, strong evidence shows it can significantly worsen the disease's progression, negatively impact treatment response, and is linked to more advanced stages, potentially by affecting the bone marrow's microenvironment and immune response through pathways like beta-adrenergic signaling. It's a factor that can accelerate cancer development and make existing leukemia harder to fight.
Causes of leukemia in adults
Scientists believe it's often a mix of genetic mutations and environmental triggers. Here are some possible reasons (Chennamadhavuni et al. 2023): Chemical exposure: Certain chemicals, like benzene (used in some industrial processes), are known to damage DNA in blood-forming cells.
In people with AML, symptoms usually develop and progress rapidly over the course of a few weeks. Because it is an aggressive cancer, treatment should start as soon as it is diagnosed.
Early signs of leukemia often mimic the flu or other common illnesses, including persistent fatigue, unexplained fever, frequent infections, easy bruising/bleeding, and night sweats, along with potential weight loss, bone pain, swollen lymph nodes, or pale skin, though some people have no symptoms initially. These vague symptoms occur due to the body's inability to produce healthy blood cells.
Leukemia Treatment
Researchers also discovered that as leukemia cells drink up taurine, it promotes glycolysis (a breakdown of glucose to produce energy) to feed cancer growth. Prior to this, the authors said, it was not known that taurine might have a cancer-promoting role. Leukemia has several subtypes and survival rates vary.
The goal of treating leukemia is complete remission. While this may not be a true "cure" in the traditional sense, it's considered the most successful outcome in those living with cancer. Experts are hesitant to use the word "cure" because the disease may recur, or come back, after remission.
Common leukemia signs and symptoms include:
Some people with leukemia or myelodysplastic syndromes have bone or joint pain. This bone pain is most often felt in the long bones of the arms and legs, in the ribs, and in the breastbone.
Leukemia is commonly misdiagnosed as the following conditions:
Leukemia starts in the soft, inner part of the bones (bone marrow), but often moves quickly into the blood. It can then spread to other parts of the body, such as the lymph nodes, spleen, liver, central nervous system, and other organs.
Acute emotional or physical stress can increase WBC counts. There are various types of white blood cells (WBCs) that normally appear in the blood: Neutrophils (polymorphonuclear leukocytes; PMNs) Band cells (slightly immature neutrophils)
Most people with leukemia are over 60. Although you can develop it at any time of life, most types are rarely diagnosed in people under 40.
Who is most at risk?
Leukemia is caused by DNA mutations in blood cells, leading to uncontrolled growth, but the exact trigger for these mutations is often unknown, likely a mix of genetic and environmental factors like radiation, benzene exposure, certain viruses, and inherited conditions (e.g., Down Syndrome). These genetic changes tell cells to keep multiplying instead of dying, crowding out healthy cells in the bone marrow.
When it comes to cancer, genetics and chance often steal the spotlight. Yet lifestyle factors—including smoking, exposure to certain chemicals, dietary habits, and more—can also sway the odds of developing leukemia.
Chronic lymphocytic leukemia (CLL) is often a silent disease during the initial stages, with many patients having no noticeable symptoms. CLL is commonly detected by accident when routine blood testing reveals an elevated lymphocyte count (lymphocytosis).
Weight loss
CLL itself uses up energy that your body would otherwise use or store. So you may lose weight, even if you eat normally.
Corticosteroids, powerful anti-inflammatory medications, are usually part of the chemotherapy regimen. Doctors also use medications that reach the spinal canal and the brain, such as methotrexate or cytarabine, to treat any cancer in these parts of the body or to prevent it from spreading there.
Leukemia symptoms include: Weakness, tiredness and fatigue. This can be caused by the leukemia itself or by the low levels of hemoglobin seen in many leukemia patients. Fever and frequent infections due to low counts of healthy white blood cells.
In the initial stages of diagnosing acute myeloid leukaemia (AML), your GP will check for physical signs of the condition and arrange for you to have blood tests. A high number of abnormal white blood cells, or a very low blood count in the test sample, could indicate leukaemia.
Complete blood count. A complete blood count (CBC) is the first test for diagnosing and monitoring leukemia. You will likely get multiple CBC tests throughout your treatment if you have leukemia. Your results help your doctors understand if your disease is advancing or how your body is responding to treatments.
Treatment
Leukemia symptoms commonly include:
So, is leukemia a hereditary disease? In most cases, the answer is no. Leukemia is largely caused by genetic mutations acquired during a person's lifetime. However, specific gene mutations can increase the likelihood of developing leukemia within families.
