Did you know, leukaemia is one of the most widespread forms of blood cancer in the world? Leukaemia cells behave like abnormal blood cells, hence it is commonly called blood cancer. Its treatment depends on the type, severity of the condition, patient’s age, gender and overall health. In this article, we are going to discuss all that you need to know about leukaemia.

What Is Leukaemia?

Leukaemia is a form of blood cancer that is characterised by the rapid growth of the blood cells. This unprecedented growth usually occurs in the bone marrow, where most of the blood is produced. These blood cells are also often referred to as abnormal white blood cells since they have no purpose in improving your immunity. Instead of helping your body, these blood cells could potentially impair the ability of the bone marrow to produce blood cells and platelets.

What Are The Various Types Of Leukaemia?

Leukaemia can be of two main types, chronic or acute. While chronic leukaemia generally has a slower progression, acute leukaemia requires immediate medical attention. 

Leukaemia can also be classified as lymphocytic or myelogenous. Lymphocytic leukaemia causes abnormal growth of cells in lymphocytes while myelogenous leukaemia causes a growth in the bone marrow cells that mature into red blood cells. The four major classifications of leukaemia include the following:

1. Acute lymphocytic leukaemia (ALL)

ALL is a cancer that primarily affects your blood and bone marrow. It specifically targets your white blood cells which can hamper your body’s ability to combat infections. It is generally more common in children than adults. However, children have higher rates of successful recovery from this disease, compared to adults.

2. Acute myelogenous leukaemia (AML)

AML is a relatively uncommon cancer that impacts both the bone marrow and blood. It is characterized by its aggressive nature. If necessary treatment is not provided early, it may become life-threatening, especially for elderly people.

3. Chronic lymphocytic leukaemia (CLL)

CLL is the most common type of blood cancer found in adults. It usually happens when healthy white blood cells in your bone marrow start mutating or change into cancerous cells. These cells multiply and overcrowd healthy blood cells and platelets.

4. Chronic myelogenous leukaemia (CML)

CML is a type of blood cancer that originates in the blood-forming myeloid cells or stem cells in your bone marrow. However, with several innovative therapies, even a life-threatening disease like CML can be treated effectively.

Symptoms Of Leukaemia

Some of the most common symptoms of leukaemia include:

Causes Of Leukaemia

While there is no definite cause of leukaemia, some risk factors may increase your chances of developing the disease. Factors that may increase your risk for leukaemia include: 

Leukaemia Complications

Several complications associated with leukaemia include:

Leukaemia Diagnosis

Leukaemia is diagnosed with the help of various blood & imaging tests. These tests include:

Annual health checkups can help in the early diagnosis of any medical condition, including cancer.

Takeaway

There is no cure for leukaemia but it is still possible to achieve long-term remission with proper care and medication.

Entire leukaemia treatment and therapy can cost anywhere from Rs. 10,94,000 to Rs. 22,00,000.

3. What is the survival rate of leukaemia?

The survival rates for all four variations of leukaemia are:

• CLL - 5-year survival rate is around 88%
• ALL - 5-year survival rate is around 71.3%
• CML - 5-year survival rate is around 70.6%
• AML - 5-year survival rate is around 31.7%

4. When should you consult a doctor?

If you experience sudden unexplained weight loss, fever, nausea, dizziness or loss of appetite, you should consult a doctor for further investigation. 

5. What is the newest treatment for leukaemia?

The Food and Drug Administration recently approved the use of a drug named zanubrutinib, which is considered to be an effective form of medication to treat CLL with minimal side effects.
