These tiny particles, called extracellular vesicles, are everywhere. They are released by cells throughout the body. This can be normal, or it can happen during disease. Even more interesting, these tiny particles can send signals to other cells. They can help start, grow, and spread cancer.

One cancer they are known for aiding is a type of cancer in the mouth and throat. This cancer is called oral squamous cell carcinoma. It is the most common type of cancer in the head and neck. Even worse, it kills a lot of people each year. Lots of scientists are now looking into it. They are trying to find out how exactly it causes the cancer to spread. And they are looking for ways to use these particles to spot the cancer early.

The particles travel around the body. They can change the environment around the tumor. They can help the tumor move and grow. They can even help it spread to other parts of the body. They can also mess with the immune system. This is the body's defense system. The immune system is designed to fight off invaders. In this case, the invaders are cancer cells. However, the immune system can be tricked into helping the cancer grow.  This can lead to creating resistance to treatments.

They can also carry proteins. These proteins can be used as signs of the cancer. A sign of something means evidence that something has taken place. If you take a blood sample, you can look for these proteins. If you find them, that can be a sign that you have cancer. These signs can be found early, even before you see any symptoms. This is important. It means you can catch the cancer earlier. Early detection can lead to getting treatment faster.  Early treatment increases your odds of survival.

Research is looking at how these proteins can be used to make sure people get treatment for cancer sooner. .  Knowing what exactly is happening to these proteins in the body. Can lead to  helping better diagnose the condition in people.  Better diagnosis can lead to saving lives.
