Leukaemia is a type of cancer that originates in the blood-forming tissues, primarily the bone marrow, leading to the abnormal production of white blood cells. These abnormal cells can interfere with the body's ability to fight infections, carry oxygen, and control bleeding. Leukaemia can occur in both children and adults and may develop rapidly or progress slowly depending on the type. Early diagnosis and appropriate treatment are important for improving outcomes and managing the disease effectively.
What are the Types of Leukemia?
It is classified by how rapidly it progresses and the type of blood cell involved.
- Acute Myeloid Leukemia (AML): AML where immature white blood cells multiply rapidly, crowding out healthy blood cells. Treatment includes aggressive chemotherapy and, in some cases, stem cell transplantation.
- Chronic Myelogenous Leukemia (CML): CML is a slow-progressing leukemia characterized by the overgrowth of myeloid white blood cells. It is often linked to the Philadelphia chromosome. Targeted therapies have revolutionized CML treatment.
- Chronic Lymphocytic Leukemia (CLL): CLL is a slow-growing cancer that affects mature lymphocytes in the blood and bone marrow. It may not require immediate treatment but can be managed with therapies like chemotherapy, immunotherapy, or targeted treatments when necessary.
- Acute Lymphocytic Leukemia (ALL): ALL is a fast-progressing leukemia, especially common in children. It involves immature lymphocytes and requires immediate, aggressive treatment with chemotherapy, targeted therapies, and stem cell transplantation in some cases.
What are the Common Causes and Risk Factors of Leukaemia?
The exact cause of leukaemia is often unknown. It develops when genetic mutations occur in blood-forming cells, causing abnormal growth and survival of white blood cells.
Several environmental, genetic, and medical factors may increase the risk.
Causes
- Genetic mutations in bone marrow cells
- Abnormal blood cell development
- Chromosomal abnormalities
- Disruption of normal cell growth regulation
Risk Factors
- Previous chemotherapy or radiation therapy
- Exposure to high levels of radiation
- Exposure to benzene and certain chemicals
- Family history of leukaemia
- Genetic disorders such as Down syndrome
- Smoking
When to See a Doctor for Leukaemia?
Persistent fatigue, unexplained bruising, recurrent infections, prolonged fever, or unusual bleeding should be evaluated by a Hematologist or Oncologist. Early diagnosis can improve treatment outcomes and reduce complications.
You should see a doctor if you experience:
- Persistent tiredness or weakness
- Frequent infections
- Easy bruising or bleeding
Seek immediate medical attention if:
- Severe bleeding occurs
- High fever develops with signs of infection
- Shortness of breath or chest pain occurs
These symptoms may indicate serious complications requiring urgent medical care.
How is Leukemia Diagnosed?
A doctor will begin by reviewing the patient's medical history and performing a physical examination. Physical examination is, however, not a trusted way to diagnose leukemia. Instead, the doctor will make diagnoses based on the following criteria:
- Blood Tests: A complete blood count (CBC) looks at the number and maturity of different types of blood cells. A blood smear is used to look for abnormal or immature cells.
- Bone Marrow Biopsy: During a bone marrow biopsy, a long needle is used to collect marrow from the pelvic bone. It can tell a doctor what sort of leukemia someone has and how severe it is.
- Spinal Tap: The removal of fluid from the spinal cord is known as a spinal tap. It can tell a doctor whether or not the leukemia has spread
- Imaging Tests: CT, MRI, and PET scans can all be used to identify leukemia.
How is Leukemia Treated?
The form of leukemia, the extent to which it has spread, and the general health of the patient affect the leukemia treatment to be provided. The following are the most important treatment options:
- Chemotherapy: It is a leukemia treatment that uses medicines to eliminate cancer cells in the blood and bone marrow. The medication is easily accessible.
- Radiation: It employs high-energy X-rays to destroy or prevent the development of leukemia cells. It can be acquired all over the body or only in one place with many cancer cells.
- Immunotherapy or Biological Therapy: It is a biological treatment that assists the immune system in finding and fighting cancer cells. Drugs like interleukins and interferon can help the body's natural defenses against leukemia.
- Targeted Treatment: It involves using drugs to stop cancer cells from growing by inhibiting specific genes or proteins. This treatment can halt the growth and multiplication of leukemia cells, cut off their blood supply, or kill them immediately.
- A stem Cell Transplant: In the bone marrow, a stem cell transplant replaces leukemia cells with new blood-producing cells. The new stem cells may originate from your own body or a donor. Chemotherapy in high dosages will kill the cancer cells in your bone marrow. The new stem cells will then be injected into one of the veins. They will mature into new, healthy blood cells.
- Surgery: The doctor may remove the spleen if it is loaded with cancer cells and pressing on other organs. The medical word for this leukemia treatment procedure is splenectomy.

What is the Recovery Process for Leukaemia?
Recovery depends on the type of leukaemia, response to treatment, and overall health. Some patients achieve long-term remission or cure, while others require ongoing therapy and monitoring.
Regular follow-up is essential to detect recurrence, manage complications, and maintain overall health.
Recovery Includes
- Regular hematology follow-up visits
- Routine blood tests
- Monitoring for recurrence
- Management of treatment side effects
- Physical and emotional rehabilitation
- Long-term survivorship care
Frequently Asked Questions
1. What are the symptoms of Leukemia?
Common symptoms include fatigue, frequent infections, fever, easy bruising or bleeding, swollen lymph nodes, bone pain, and unexplained weight loss.
2. How is Leukemia diagnosed?
Diagnosis typically involves blood tests, bone marrow biopsy, imaging studies, and genetic testing to identify the type and extent of the disease.
3. What are the different types of Leukemia?
The main types include Acute Lymphoblastic Leukemia (ALL), Acute Myeloid Leukemia (AML), Chronic Lymphocytic Leukemia (CLL), and Chronic Myeloid Leukemia (CML).
4. Is Leukemia hereditary?
Most cases of leukemia are not inherited, but certain genetic conditions and family history may increase the risk of developing the disease.
5. How is Leukemia treated?
Treatment may include chemotherapy, targeted therapy, immunotherapy, radiation therapy, stem cell transplantation, or a combination of these approaches.
6. Can Leukemia be cured?
Some types of leukemia can be cured, especially when diagnosed and treated early. Treatment outcomes depend on the type of leukemia, age, and overall health of the patient.
7. Who is at risk of developing Leukemia?
Risk factors include older age, smoking, exposure to radiation or certain chemicals, family history, and certain genetic disorders.
8. What complications can occur with Leukemia?
Complications may include severe infections, anemia, bleeding problems, organ involvement, and side effects related to treatment.
9. What is the prognosis for Leukemia?
The prognosis varies depending on the type of leukemia, stage of disease, response to treatment, and individual patient factors. Many patients achieve long-term remission with modern therapies.
