A brain tumor is a disease that continues to be a major cause of mortality. Brain tumors are the abnormal, uncontrolled growth of cells in the brain. These cells grow and multiply in an uncontrolled way.
This can interfere with the normal functioning of your brain, causing symptoms like headaches, seizures, and weakness, which you may notice at first. Brain tumors can also grow to exert pressure on other parts of your body, blocking the normal flow of blood and oxygen to your brain and spinal cord, which can cause symptoms in other parts of your body.
Brain tumors are mostly diagnosed in adults, but they can occur at any age. Brain tumors are classified by the type of cell they start in, where they start and how they grow. Brain tumors symptoms are not easy to spot as the signs and symptoms of a brain tumor develop slowly and often mimic the signs of other diseases.
In some cases, the symptoms of brain tumors may be the only indication of a brain tumors diagnosis. If you have ever wondered “what is brain tumor?”, it is important to know the symptoms of brain tumors so that you can seek treatment early if you suspect that you may be experiencing brain tumors symptoms.
What are Brain Tumors?
Brain tumors are a type of cancerous tumor that develops in the brain or spinal cord. tumors that start in the brain are called primary brain tumors and those that start in the spinal cord are called primary spinal cord tumors.
The cells that make up a tumor have lost the ability to stop dividing and have started to grow in an uncontrolled way. Brain tumors are usually named after the type of cell they are made up of. The most common type of brain tumor is glioma. Gliomas are tumors that start in the glial cells.
Glial cells support and protect the nerve cells in your brain. Most types of glioma are called glioblastomas. Glioblastomas are the most common and deadliest type of brain tumor.
Is Brain Tumor Cancer?
A brain tumor is a mass of cells that grows in the brain. It can be benign or cancerous. Benign tumors aren’t cancerous and don’t spread to other parts of the body. They’re called “benign” because they don’t tend to spread. Malignant tumors are cancerous and can spread to other parts of the body.
They’re called “cancerous” because they can grow and spread out of control. Brain tumors can begin in different types of cells within the brain. These cells can be healthy and normal, and are often called “pre-cancerous cells.” Some grow into tumors more quickly than others. Most tumors start in the brain’s nerve cells (neurons), which control how we move and feel.
Main Cause of Brain Tumor
Some head and neck tumors are caused by genetic defects or inherited gene defects. In these cases, there’s a clear genetic cause. In other cases, these tumors are caused by changes in DNA that are not inherited but happen during a person’s lifetime. These changes, called mutations, most often occur by chance.
They can happen randomly during the copying of DNA when a cell divides to create new cells. These mutations can also occur because of exposure to substances in the environment (such as tobacco, alcohol, and radiation) or to infectious diseases like human papillomavirus (HPV).
