A brain tumor diagnosis can look like a life threatening scenario. But even though the symptoms of most common brain tumors are the same, not all tumors are malignant. In this article, we are going to have a look at some of the most common types of brain tumor that is prevalent in the present scenario.
What Is Brain Tumor?
A brain tumor is a growth or mass of abnormal cells in your brain. Several varied forms of brain tumors prevail. There are some brain tumors that are noncancerous and there are some tumors that are cancerous. Brain tumors can start in your brain (basically brain tumor), or cancer can start in other sections of the body and they spread to your brain as secondary brain tumors.
How fast a brain tumor can evolve can defer greatly. The rate of growth along with the location of a brain tumor evaluates how it will impact the operation of your nervous system. Brain tumor treatment categories depend on the forms of brain tumors you have along with their location and size. There are various causes of brain tumors, but today we are not going to talk about that. Today let us have a look at the various types of brain tumors in adults.
List Of 4 Most Common Brain Tumors
There are nearly 130 varied forms of brain and central nervous system tumors, all varying from benign brain tumors to malignant, and from highly rare to relatively common. But among those 130 brain tumors, which are the most common? On this World Brain Tumor Day, let us be aware of the most common brain tumors.
The most common brain tumors in adults, metastatic tumors are categorized as secondary brain tumors, which implies they arise from cancer that was created elsewhere in the human body and then spread to the brain. Even though exact incidence rates are unknown, the American Brain Tumor Association anticipates between 200,000 and 300,000 metastatic brain tumors are identified every year. According to Dr. Lustig, who also mentioned that metastatic tumors most often stem from breast or lung cancer.
Larger metastatic tumors will seldom be surgically resected which implies removal, while smaller tumors may be processed with a gamma knife, which is a type of radiation therapy that aims 200 small beams of radiation onto the tumorous area.
These tumors are mechanically not brain tumors, as they shape in the pleura, which are the membranes that line the skull and the vertebral canal. But their growth may impact the brain by creating several disabilities like hearing and vision impairment, memory loss, or also seizures. Incidents of meningioma raise with age, and the tumors evolve slowly, so symptoms could originate gradually over time. Dr. Lustig said in an interview that many meningiomas are benign, so doctors may select to leave asymptomatic cases alone. However, if the tumor begins adversely impacting the quality of life, physicians will either surgically discard it or treat it using radiation therapy. As per doctors, the most common early sign of meningioma is chronic headaches.
Even though this is the third most common brain tumors, Glioblastoma is the most common basic tumor, which implies it begins in the brain. It is also among the most lethal brain tumors. Approximately 15,000 new scenarios of Glioblastoma are diagnosed each year, Glioblastoma has created headlines for taking the lives of senators Ted Kennedy and John McCain along with Beau Biden, the son of former Vice President Joe Biden. A complete range of treatment advances is often used for fighting Glioblastoma, which includes surgical resection, chemotherapy, and radiation therapy.
These tumors originate in star shaped cells that are known as astrocytes, which are situated in the cerebrum of the brain. The grade of Astrocytoma tumor which implies their level of aggressiveness and malignancy. Treatment strategies for Astrocytoma always include surgery, and at times include radiation and chemotherapy. In comparison to other tumors mentioned in this list, Astrocytoma has more positive complete survival rates. For patients between the age group of 20-44, the rate of survival for low grade Astrocytoma is nearly 68%, decreasing to 44% for patients between the age of 45-54.
As a whole, constant headaches are the earliest and most common signs of brain tumors. Having said that, headaches are quite a regular occurrence in our daily life. According to experts, there are various ways to differentiate headaches from ones that may be related to a larger issue like a brain tumor. Some of the brain tumor warning signs would be if the frequency and intensity of your headache increase over days and weeks, and if your headaches become so severe that they wake you up when you are sleeping.
Treatment for brain tumors is often successful and it is possible to completely recover. However, the outlook of the brain tumor can vary on different grounds like the type of tumor, the size of the tumor, your general health, and the location of your tumor. Getting treatment early can stop you from entering complications that can happen as the tumor grows from spreading to other tissues in the brain. With the help of the above guide on the most common brain tumors, you can understand this matter better.
