Causes of leukaemia The cause of acute leukaemia is unknown, but factors that put some people at higher risk are: exposure to intense radiation. exposure to certain chemicals, such as benzene. viruses like the Human T-Cell leukaemia virus.
Age – Generally speaking, individuals over the age of 65 are more at risk for leukemia. Demographics – While anyone can conceivably develop leukemia, white males are statistically most susceptible. Radiation exposure – Exposure to radiation from an atomic bomb increases the likelihood that leukemia cells will form.

Acute leukemia symptoms can often appear suddenly
With acute leukemia, symptoms tend to develop very quickly. You may suddenly spike a fever that won't go away, develop an infection for no apparent reason, or start bleeding spontaneously from your nose or gums and not be able to stop it.
Chronic Leukemia May Go Undetected
It may take months or even several years before the disease begins to cause symptoms that alert the patient that something is wrong.
Unlike symptoms of the flu, which generally subside as patients get better, leukemia symptoms generally last longer than two weeks, and may include sudden weight loss, bone and joint pain and easy bleeding or bruising. Other early warning signs of leukemia include: Fever, chills. Fatigue, weakness.
Decreased appetite. Weight loss. Enlarged spleen and/or lymph nodes. Recurring or chronic infections in areas such as the skin, lungs, or kidneys.
Chemicals: Long-term exposure to certain pesticides or industrial chemicals like benzene is considered a risk for leukemia. Electromagnetic fields: Prolonged exposure, such as living near power lines, may increase a person's risk for developing ALL.
Many studies suggest that short sleep duration increases the risk of cancer whereas some find associations between certain cancers and long sleep duration. Other studies find no definite link at all between how long we sleep for and our risk of cancer.
Stage 1 – A patient has high levels of white blood cells and enlarged lymph nodes. Stage 2 – A patient has high levels of white blood cells and is anemic. He or she may also have enlarged lymph nodes. Stage 3 – A patient has high levels of white blood cells and is anemic.
Leukemia can produce a variety of symptoms, although most are not often apparent in the earliest stages of the malignancy. The most common symptoms of leukemia—fatigue, pale skin, weight loss and night sweats—are often attributed to other less serious conditions, such as the flu.
Acute leukemia may cause signs and symptoms that are similar to the flu. They come on suddenly within days or weeks. Chronic leukemia often causes only a few symptoms or none at all. Signs and symptoms usually develop gradually.
Leukemia cells can spread to the central nervous system and build up in the fluid surrounding the spine and the brain. This can cause symptoms like headaches, seizures, balance problems, and abnormal vision.
Blood tests are essential to accurate diagnosis of this complex disease. These tests can show whether you have leukemia cells or abnormal levels of normal cells: Blood smear: With this test, we take a drop of blood and look at it under a microscope.
If acute leukemia is left untreated, a person with leukemia becomes increasingly susceptible to fatigue, excessive bleeding and infections until, finally, the body becomes virtually defenseless, making every minor injury or infection very serious. Leukemia may be fatal.
During the progression of leukemia, white blood cells (neoplastic leukocytes) found in bone marrow may begin to filter into the layers of the skin, resulting in skin lesions. “It looks like red-brown to purple firm bumps or nodules and represents the leukemia cells depositing in the skin,” Forrestel says.
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 lymphoblastic leukaemia (ALL) is a type of blood cancer. It starts from white blood cells called lymphocytes in the bone marrow. The bone marrow is the soft inner part of the bones, where new blood cells are made. ALL usually develops quickly over days or weeks.
Leukemia is a type of cancer that develops in the lymphoid cells in the bone marrow or lymphatic system. It most commonly affects white blood cells, making it harder for a body's immune system to fight infection.
If caught early, leukemia can be cured by undergoing several cancer treatments.
