Diabetes and Breast Cancer: Today’s runaway life and unhealthy lifestyle have given rise to many serious diseases. One of them is Type-2 diabetes, which people often ignore as “sugar disease”. But do you know that this disease is not limited to blood sugar just? New research has revealed that type-2 diabetes can make breast cancer more aggressive. Yes, this disease makes dangerous disease like breast cancer even more dangerous. Let us know what shocking things scientists have told about this.

New study opened big secret

Researchers at Chobanian and Awedician School of Medicine at Boston University, USA have made a shocking discovery. Their study suggests that type-2 diabetes changes the body’s immune system. This change weakens the immune cells inside the breast cancer tumor. outcome? The body does not stop the growth of tumors, and breast cancer begins to spread rapidly.

Research found that small particles present in the blood of diabetes patients, called exosomes, replace immune cells inside the tumor in such a way that they lose their strength. This discovery is special because for the first time it has been proved that diabetes can suppress the activity of the immune system in breast cancerous tumors.

How did scientists discover?

Researchers took samples from tumors of breast cancer patients and prepared 3D tumor models in the lab. He then understood how immune cells work inside the tumor using modern technology like single-cell RNA sequencing. This research made it clear that diabetes makes the tumor atmosphere more complicated.

Why is breast cancer complex?

Breast cancer is a complex disease in itself. If a patient also has type-2 diabetes, the results of the treatment may be worse. Scientists say, “Our study showed that diabetes changes the immune system inside the tumor. That is why modern technologies like immunotherapy are not as effective on these patients.”

Aggressive breast cancer risk

There are many types of breast cancer. Some grow slowly, such as DCIS, LCIS and Philoids Tumors, while some are extremely aggressive, such as triple-negative, inflammatory and angiosarcoma. According to the American Cancer Society, aggressive breast cancer cases are increasing rapidly in women under 40 years of age, which is a matter of concern.

What is type-2 diabetes?

According to the World Health Organization (WHO), type-2 diabetes occurs when the pancreas is not able to make enough insulin or the body is unable to use that insulin properly. Insulin is the hormone that controls blood sugar. When this balance deteriorates, the level of blood sugar increases, which can damage the heart, kidney, veins and eyes.

Therefore, it can be dangerous to ignore diabetes as just a “sugar disease”. The disease changes the immune system so much that a serious disease like breast cancer becomes even more dangerous.
