A brain tumour is a growth of cells in the brain that multiplies in an abnormal, uncontrollable way. Grades and types of brain tumour. Brain tumours are graded according to how fast they grow and how likely they are to grow back after treatment. Grade 1 and 2 tumours are low grade, and grade 3 and 4 tumours are high grade.

This is called raised intracranial pressure. It can be caused by the size of the tumour, swelling around the tumour, or because the tumour is blocking the flow of fluid in the brain. The most common symptoms of this are headaches, feeling sick and vomiting. The headache may be worse in the morning or get worse when you cough, sneeze or bend down.
A malignant brain tumour is a cancerous growth in the brain. It's different from a benign brain tumour, which isn't cancerous and tends to grow more slowly. Symptoms. The symptoms of a brain tumour depend on where it is in the brain. Common symptoms include: headaches (often worse in the morning and when coughing or straining) fits (seizures)

Brain tumor Types
There are many types of brain tumors. The type of brain tumor is based on the kind of cells that make up the tumor. Special lab tests on the tumor cells can give information about the cells. Your health care team uses this information to figure out the type of brain tumor. Some types of brain tumors usually aren't cancerous. These are called noncancerous brain tumors or benign brain tumors. Some types of brain tumors usually are cancerous. These types are called brain cancers or malignant brain tumors. Some brain tumor types can be benign or malignant. Benign brain tumors tend to be slow-growing brain tumors. Malignant brain tumors tend to be fast-growing brain tumors.
The signs and symptoms of a brain tumor depend on the brain tumor's size and location. Symptoms also might depend on how fast the brain tumor is growing, which is also called the tumor grade.
General signs and symptoms caused by brain tumors may include:
•Headache or pressure in the head that is worse in the morning.
•Headaches that happen more often and seem more severe.
•Headaches that are sometimes described as tension headaches or migraines.
•Nausea or vomiting.
Brain tumors that begin in the brain
Brain tumors that start as a growth of cells in the brain are called primary brain tumors. They might start right in the brain or in the tissue nearby. Nearby tissue might include the membranes that cover the brain, called meninges. Brain tumors also can happen in nerves, the pituitary gland and the pineal gland. Brain tumors happen when cells in or near the brain get changes in their DNA. A cell's DNA holds the instructions that tell the cell what to do. The changes tell the cells to grow quickly and continue living when healthy cells would die as part of their natural life cycle. This makes a lot of extra cells in the brain. The cells can form a growth called a tumor. It's not clear what causes the DNA changes that lead to brain tumors. For many people with brain tumors, the cause is never known. Sometimes parents pass DNA changes to their children. The changes can increase the risk of having a brain tumor. These hereditary brain tumors are rare. If you have a family history of brain tumors, talk about it with your health care provider. You might consider meeting with a health care provider trained in genetics to understand whether your family history increases your risk of having a brain tumor. When brain tumors happen in children, they're likely to be primary brain tumors. In adults, brain tumors are more likely to be cancer that started somewhere else and spread to the brain.
In most people with primary brain tumors, the cause isn't clear. But doctors have identified some factors that may raise the risk.
Risk factors include:
•Age. Brain tumors can happen at any age, but they happen most often in older adults. Some brain tumors mostly affect adults. Some brain tumors happen most often in children.
•Race. Anyone can get a brain tumor. But some types of brain tumors are more common in people of certain races. For example, gliomas are more common in white people. Meningiomas are more common in Black people.
•Exposure to radiation. People who have been exposed to a strong type of radiation have an increased risk of brain tumor. This strong radiation is called ionizing radiation. The radiation is strong enough to cause DNA changes in the body's cells. The DNA changes can lead to tumors and cancers. Examples of ionizing radiation include radiation therapy used to treat cancer and radiation exposure caused by atomic bombs.
Low-level radiation from everyday objects isn't linked to brain tumors. Low levels of radiation include the energy that comes from cellphones and radio waves. There is no convincing evidence that using cellphones causes brain tumors. But more studies are happening to make sure.
There's no way to prevent brain tumors. If you get a brain tumor, you didn't do anything to cause it.
People with an increased risk of brain tumor might consider screening tests. Screening isn't brain tumor prevention. But screening might help find a brain tumor when it's small and treatment is more likely to be successful.
May 21, 2023 · Non-cancerous (benign) brain tumours and cancerous (malignant) primary brain tumours are uncommon. Overall they occur in about 12 in 100,000 people each year. The most common types in adults are benign meningioma and a glioma called glioblastoma multiforme. Some types are very rare. Brain tumours can occur at any age.
Pituitary gland tumour symptoms. The pituitary gland makes hormones that are important for your body to function. A tumour in this area of the brain can cause: weight gain. infertility. mood changes. high blood pressure. high blood sugar levels (diabetes) leakage of milk from the breasts when you're not breastfeeding.
