Question

In leukemia (blood cancer), leucocyte count is
A.> 1 lakh
B.<10,000
C.10 - 20,000
D.None of the above

Answer 1

Leukemia is a condition where abnormalities in white blood cell production cause excessive production of underdeveloped white blood cells, which ultimately destroy normal cells. This condition can be acute or chronic and is commonly diagnosed through a blood test. Normal individuals would have a leucocyte count of up to 4,000 to 10,000 whereas leukemia patients will have leucocyte counts of above 1 lakh to 4 lakhs.
Complete step by step answer:
Leukemia, a form of blood cancer affects the production and functioning of leukocytes within the body. This can be caused by various factors such as genetic disorders, exposure to carcinogenic substances, radiation, or even lifestyle habits such as smoking.
Here, the white blood cells or leukocytes, are produced rapidly in large numbers within the bone marrow and are underdeveloped or poorly developed cells. This poorly developed leucocyte prevents the normal functions of other plasma cells and beyond a point causes irreparable damage and leads to several fatalities.
In a normal individual, the leucocyte count is around 4000 to 10,000 cells per microliter. The leucocyte count is generally low and is only found in elevated numbers during an infection. Whereas in the case of leukemia patients, the normal leukocyte count would be around 1 lakh to 4 lakhs. Blood tests are the most common and effective methods to diagnose leukemia.
Therefore, the correct option is A.> 1 lakh

Note:
This is a cancerous condition of leucocyte which is also known as white blood cells.
This can include both lymphoid cells such as T-cell and B-cell as well as myeloid cells such as granulocytes and agranulocytes.
The condition causes excessive production of leukocytes which inhibit other metabolic functioning of the body.
