It turns out that stressful life triggers that deadly disease! Newly tested on mice

In the latest research by scientists, it was found that stress causes cancerous cells to grow and spread. Here is the effect of stress on cancer...

A team from Cold Spring Harbor Laboratory in New York, US, found that chronic stress leads to the formation of sticky networks of white blood cells called neutrophils , making it easier for cancer cells to invade tissues.

The team conducted their research on laboratory mice with breast cancer. When mice were stressed, the risk of cancer spreading increased 2 to 4 times.

While the study appears to confirm that stress promotes the growth of cancer, it does not prove that stress causes tumors in the first place.

"IT IS VERY IMPORTANT TO UNDERSTAND HOW STRESS WORKS ON US"
Stress also affects other parts of the immune system, such as suppressing the activity of important immune cells, making the lungs a more suitable place for cancer cells to proliferate.

Researcher Dr. from Cold Spring Harbor Laboratory. " Stress is something we really can't avoid in cancer patients. You can imagine that once you're diagnosed, you can't stop thinking about your illness, your insurance, or your family. That's why it's so important to understand how stress works on us," said Xue-Yan He.

A LESION OCCURRED IN HIS LUNGS
According to the news in Sözcü, the mice had breast tumors and cancer that had spread to their lungs. They were divided into a control group and a group to be placed under stressful conditions.

In their study, stressed mice showed greater tumor growth and spread to the lungs compared to mice that were not placed under stressful conditions, such as being constantly under bright light, sitting in a tilted cage, hearing loud noises, and being deprived of food.

Co-author of the study, Dr. "I saw this frightening increase in metastatic lesions in these animals. There was up to a fourfold increase in metastasis," said Mikala Egeblad .

"STRESS HORMONE CREATED CANCER CELLS"
Stress also caused a decrease in the number of immune cells such as T cells and natural killer (NK) cells, while also increasing the number of neutrophils circulating through the bloodstream and entering tumors.

They also found that the stress hormone corticosterone promoted the spread of cancer and caused lesions to form in the lungs of the mice.

Apart from this, it accumulated more of a protein called fibronectin, which encourages the invasion of tumor cells and leads to a decrease in T cells that normally suppress cancer growth.

The research was published in the journal Cancer Cell.
