6 differences between normal and cancer cells

The first goal and the only wish of cancer scientists and researchers are to find a way to kill cancerous cells. They constantly search for how to block the hyperactivity of cancer cells and make them die like normal cells.

So, some questions jump to mind always about this topic; first, how do the normal cells die? Second, what is the difference between normal cells and cancerous cells? Third, how do cancerous cells die? And is there any possibility of these cells dying naturally? Fourth and last, what are the symptoms of growing cancer cells again?

How do normal cells die?

Normal cells have a typical cycle; this cycle starts by producing new cells, then divide and dies in the end. Let’s know more about the cells cycle; there are 2 primary stages in this cycle:

Interphase stage:

It is the longest stage in the cycle, and during it, the cell starts to grow to its maximum size, replicates its DNA, and prepares for cell division. This phase divides into 3 parts G1, G2, and S phases.

Mitotic phase (M-Phase):

Here, in this phase, the cell divides the transfers one copy of its DNA to 2 identical cells, which are called daughter cells. This phase is composed of 2 coupled processes, mitosis and cytokinesis.

Mitosis process:

in the cell, nucleus chromosomes separate into 2 identical sets in 2 nuclei.

Cytokinesis process: the cytoplasm, organelles, and cell membrane start to divide into 2 cells containing the same equal shares of these cellular components.

So, What is the G0 phase?

It is called the resting phase, and here the cell stops dividing, stops preparing to split, and exits the cell cycle, this is according to study.com.

That’s the normal process that every cell should go through. But what happens with cancerous cells is really different. Let’s find out the differences.

Differences between normal cells and cancerous cells?

As we explained above, each cell reaches the time to die, but what happens in the cancer cells is that instead of dying, they multiply and start to reproduce abnormal cells; these cells can invade body parts like the breast, brain, and lungs. They also may attack other parts of your body by flowing through the blood and the lymphatic system.

If you have cancer, this knowledge will help you understand more about what exactly happens in your body.

Difference 1: Cancer cells keep growing and dividing:

The body gives orders and signals to cells to stop dividing, but cancer cells ignore these orders and continue splitting; here, it ignores the programmed cell death (apoptosis) too, which tells the body that it is the time to get rid of cells. Normal cells are good listeners to the body; they stop reproducing cells when there are already enough cells.

Difference 2: No time for cancer cells to mature:

Normal cells divide and mature into different cell types. And each type of cell has its function, like liver cells that remove alcohol from your blood and metabolize carbohydrates, fats, and proteins, while cancerous cells multiply with no chance to mature enough to become the cell they set out to be.

Difference 3: Cancer cells harm normal cells:

Yes, cancer cells may influence normal cells badly and affect their behavior. They affect molecules and blood vessels that locates close to the tumor too.

Cancerous cells order the close normal cells to develop new blood vessels to keep the tumor alive and extend it with blood, oxygen, and nutrients.

Difference 4: Cancer cells deceive the immune system:

You know well that your immune system helps fight diseases and infections. Usually, it gets rid of damaged or abnormal cells, but cancer cells can avoid and evade this process, allowing them to grow and develop.

Difference 5: cancer cells invade the body:

As we mentioned before, normal cells listen to body signals while cancer cells do not. It ignores the orders to stop dividing and start developing and invading the tissues nearby and spreading to other body parts. In the case of benign, it pushup the nearby tissues but never invade them.

Difference 6: The high ability to spread:

Cancer cells can spread to all body organs. Normal cells know their place well and stay put. Metastatic cancer spreads from a part to a part like breast cancer when spread from breasts to lungs; its name here a metastatic, not lung cancer.

If you already have cancer, you should follow up gradually with your doctor to ensure that you follow the best suitable treatment plan for your case. If you dought about symptoms you feel, don’t hesitate to consult a professional online health care provider.
