Brain cancer happens when cells in the brain begin to grow in an uncontrolled way and form a mass called a tumor. Tumors can be benign (non-cancerous) or malignant (cancerous), and they can affect how the brain works depending on where they are and how fast they grow.
When doctors suspect brain cancer, they start by listening to the person’s symptoms and doing a neurological exam. This checks things like balance, movement, speech, and thinking. To see inside the brain, doctors use imaging tests such as MRI (Magnetic Resonance Imaging) or CT (Computed Tomography) scans. These tests help find any abnormal growths and show their size and location. In some cases, a biopsy taking a small tissue sample is done to confirm whether the tumor is cancerous.
Signs and Symptoms That Lead to Diagnosis
The signs of a brain tumor vary depending on where it is and how big it is. Some common symptoms include:
Persistent or severe headaches
Seizures (sudden uncontrolled electrical activity in the brain)
Changes in vision, hearing, or speech
Weakness, numbness, or difficulty moving parts of the body
Problems with balance or coordination
Memory issues and changes in mood or behaviour
Nausea or vomiting without a clear cause
These symptoms don’t always mean brain cancer, but if they last for weeks or are getting worse, a careful evaluation is important.
Causes and Risk Factors
The exact cause of many brain cancers is not always known. Some risk factors include:
Changes in genes that control cell growth
Exposure to certain types of radiation
A family history of brain tumors or related genetic conditions
Weakened immune system
Most of the time, there is no single clear cause.
After Diagnosis
After a diagnosis, doctors determine what type of tumor it is and how it is affecting the brain. This information helps guide decisions on the best path forward.

Do the majority of the people with brain cancer live or die?
The brain cancer survival rate indicates the percentage of people with a certain type and stage of brain cancer who survive the disease for a specific period of time after their diagnosis. In most cases, statistics refer to the 5-year brain cancer survival rate. The 5-year brain cancer survival rate is the percentage of people who are alive 5 years after a brain cancer diagnosis, whether they have few or no signs or symptoms of brain cancer, are free of disease, or are having treatment for brain cancer. The brain cancer survival rate is based on large groups of people, and it cannot be used to predict what will happen to a particular patient. No two patients are alike, and brain cancer treatment and responses to treatment vary greatly.http://cancer.emedtv.com/brain-cancer/brain-cancer-survival.html
How many people have brain tumours?
The Commission on Cancer collects this information. I found a link (below) that you can try. You'll need to choose your state, gender, race and cancer type (brain is an option). It will break down how many people were diagnosis with this.

What does a PET scan show?
PET scans are used most often to find tumors and cancer. They're also used to look at brain activity and also used in heart disease diagnosis.
How was brain cancer first discovered?
Brain cancer was first recognized in the early 19th century through postmortem examinations of patients who had neurological symptoms. As medical knowledge grew, advances in imaging technologies such as MRI and CT scans helped in the early detection and diagnosis of brain tumors. This led to further understanding of the different types of brain cancer and development of treatment options.
What type of brain cancer does John McCain?
John McCain was diagnosed with a glioblastoma, which is a highly aggressive type of brain cancer. Glioblastoma arises from glial cells in the brain and is known for its rapid growth and resistance to treatment. McCain publicly announced his diagnosis in July 2017, and he fought the disease until his passing in August 2018.
What kind of cancer would cause headaches and blurred vision?
Brain cancer, particularly tumors located in the regions of the brain that control vision and coordination, can cause symptoms such as headaches and blurred vision. It is important to consult with a healthcare professional for a proper diagnosis and treatment plan.
What does a definite diagnosis of prostate cancer require?
A definite diagnosis of prostate cancer, however, requires a tissue biopsy.
Is breast cancer the primary diagnosis or the masectomy the primary diagnosis?
Breast cancer is the primary diagnosis, as it refers to the disease itself, while a mastectomy is a surgical procedure performed to treat or manage that diagnosis. The mastectomy is a treatment option for breast cancer, and it is not classified as a diagnosis. Therefore, breast cancer remains the primary concern in clinical records and treatment discussions.

An MRI may show brain changes in a patient that has bacterial meningitis. However, the diagnosis is not given based on images alone.
