Do you have 'Blast Cells' in your Blood Report? Let's talk about this simply (Blast Cells)

Have you ever seen the word 'Blasts' when looking at your blood report? It's normal to feel a little scared and curious when you see it. Because this unfamiliar word actually says a lot about our health. So today, let's talk about what these Blast Cells are, how they are important to our body, and what their increased number indicates. Don't worry, let's understand this simply.

What are Blast Cells in simple terms?

Simply put, blast cells are "baby cells" or immature cells. Like a baby. These are the cells that later mature, that is, grow up, and become the different types of cells that our bodies need. But if your lab report mentions "blasts," it most likely refers to immature blood cells . Hematologists and oncologists look at the number of these blast cells in your blood to make conclusions about various blood-related diseases.

What is the difference between Stem Cells and Blast Cells?

This is also something that confuses many people. Think of stem cells as the "original cell" that starts everything. It's like a lump of clay. We can make anything from that lump of clay, like a pot, a cup, anything. That's how stem cells are. They can become any type of cell.

Blast cells are the next step in the development of these stem cells. Now we've started to make a pot out of that lump of clay, and it's taking shape. Now we can't make it into a cup again. So, a blast cell is a cell that has started to go on a specific journey. That is, it has decided to become a red blood cell, a white blood cell, or a platelet. That's why blast cells are also called "precursor cells."

The function of blast cells in our body and where they are formed

Blast cells are just one stage in the process of blood formation in our body. We call this blood formation process `Hematopoiesis`. This mainly happens inside our bone marrow . The bone marrow is like the blood-making factory of our body.

Inside this factory, the main stem cell called the `Hematopoietic Stem Cell (HSC)` gives rise to two main types of blast cells:

• Myeloblast: These blast cells later grow to become red blood cells (which carry oxygen), some types of white blood cells (granulocytes - which fight infection), and platelets (which help the blood clot).
• Lymphoblast: These blast cells later develop into lymphocytes, another important type of white blood cell (an important part of the immune system).

What causes an increase in blast cells?

Blast cells should make up less than 5% of the total number of cells in a healthy person's bone marrow. Also, there should be no blast cells in the bloodstream of a healthy person.

If you have an increased number of blast cells in your bone marrow or blood, it could be a sign of a blood cancer such as leukemia, especially if these cells look abnormal when viewed under a microscope.

You can get a better understanding of this from the table below.

Can blast cells multiply without causing cancer?

Yes, you can. This is very important. An increase in blast cells does not always mean cancer. Some non-cancerous conditions and treatments can also cause blast cells to temporarily enter the blood.

• Serious Infections: When the body develops a serious infection like `Sepsis`, our body starts producing excessive amounts of white blood cells to fight the infection. At this time, some immature blast cells may also enter the blood from the bone marrow.
• G-CSF treatment: When undergoing cancer treatments like chemotherapy, the white blood cells decrease. At that time, an injection called `Granulocyte-colony stimulating factor (G-CSF)` is given to stimulate the production of white blood cells. This injection can also temporarily increase the number of blast cells in the blood.
• Stem cell transplants: After stem cell transplants for a certain condition, the number of blast cells may increase during the process of new blood formation.

But the important thing is that these non-cancerous blast cells usually look healthy under the microscope. They can do their job when they grow. In cancer, we see abnormal, misshapen blast cells.

How do you check the blast cell level?

Doctors use several main tests to learn about blast cells.

• Peripheral Blood Smear (PBS): This involves smearing a drop of your blood on a glass slide and looking at it under a microscope. This can give a rough idea of ​​whether there are blast cells in the blood, what they look like, and what the percentage is.
• Bone marrow tests: This is the best way to get the most accurate and complete information about blast cells. A bone marrow biopsy or aspiration involves taking a small needle from a large bone, such as the hip bone, and taking a sample of the bone marrow. It is then tested in a lab to determine the percentage of blast cells and their exact nature.
• Complete Blood Count (CBC): This checks your red blood cell, white blood cell, and platelet counts. When blast cells increase, the number of these healthy cells can decrease.

So don't panic if you see 'blasts' on your report. It can be a sign of something serious, and sometimes it can be a temporary condition. The most important thing is to talk to your doctor about it and follow his advice. He will refer you to a blood specialist if necessary.
