A brain tumour is a growth of brain cells or cells close to the brain. The tissue of the brain can develop brain tumours. Near the brain tissue, brain tumours are also possible. The pituitary gland, pineal gland, and membranes that surround the surface of the brain are nearby structures.
Brain tumours can start there. Primary brain tumours are what they are. Cancer can occasionally move from another section of the body to the brain. These tumours are what are known as metastatic or secondary brain tumours.
Many different types of primary brain tumors exist. Some brain tumors aren’t cancerous. These are called noncancerous brain tumors or benign brain tumors. Noncancerous brain tumors may grow over time and press on the brain tissue. Other brain tumors are brain cancers, also called malignant brain tumors. Brain cancers may grow quickly. The cancer cells can invade and destroy the brain tissue.
Brain tumours can be very little or quite enormous in size. Because they produce symptoms that you can immediately identify, some brain tumours are discovered while they are very little. Before they are discovered, other brain tumours enlarge considerably. The brain has several regions that are more and less active. If a brain tumour develops in a less active area of the brain, symptoms may not appear right away. Before the tumour is found, its size may increase significantly.
The sort of brain tumour you have, as well as its size and location, all affect your treatment options. Radiation therapy and surgery are frequent forms of treatment.
Brain tumours can take many different forms. The kind of cells that make up the tumour determine the type of brain tumour. On the tumour cells, specialised lab tests can reveal information about the cells. This data is used by your medical team to identify the kind of brain tumour.
There are some brain tumours that are often not malignant. These are benign brain tumours, sometimes known as non-cancerous brain tumours. Brain tumours of some forms are frequently malignant. Malignant brain tumours or brain cancers are the names for these kinds. There are both benign and malignant varieties of brain tumours.
Slow-growing brain tumours are frequently benign. Brain tumours with malignancy frequently grow quickly.
The following types of brain tumours:
1 Gliomas and related brain tumours
Gliomas are cell growths that resemble glial cells. In the brain tissue, glial cells encircle and support nerve cells. Astrocytoma, glioblastoma, oligodendroglioma, and ependymoma are a few examples of gliomas and related brain tumours. Although benign gliomas can occur, the majority do. The most typical form of malignant brain tumour is glioblastoma.
2 Choroid plexus tumours
The cells that produce the fluid that covers the brain and spinal cord are where choroid plexus tumours originate. Cerebrospinal fluid is the name of this substance. The fluid-filled spaces in the brain called the ventricles are where choroid plexus tumours are found. Tumours of the choroid plexus can be benign or cancerous. The malignant variation of this sort of brain tumour is choroid plexus carcinoma. The prevalence is higher in kids.
3 Embryonal tumours
Cells that are left behind from foetal development are where embryonic tumours start. After birth, the embryonal cells continue to exist in the brain. Malignant brain tumours called embryonal tumours most frequently affect infants and young children. Medulloblastoma is the most prevalent kind of embryonal tumour. The cerebellum, a region of the brain in the back, is often where it is located.
4 Germ cell tumours.
Germ cells, which develop into sperm and egg cells, are where germ cell tumours originate. Most germ cells are found in the testicles and ovaries. However, occasionally they can also be found in the brain and in other organs. In the brain, germ cell tumours frequently develop close to the pituitary or pineal glands. Most benign tumours are made of germ cells. Children are more likely to have them.
5 Pineal tumours
Pineal tumours begin in and around the pineal gland in the brain. In the middle of the brain is where the pineal gland is situated. It produces melatonin, a hormone that promotes sleep. Pineal tumours can either be benign or cancerous. The most prevalent type of malignant pineal tumour in children is called pineoblastoma.
Brain tumours called meningiomas begin in the membranes that surround the brain and spinal cord. Although meningiomas are typically benign, they can occasionally be cancerous. The most typical kind of benign brain tumour is meningioma.
7 Nerve tumours
Growths within and around nerves are referred to as nerve tumours. The auditory neuroma, also known as schwannoma, is the most prevalent form that develops in the head. The primary nerve that connects the inner ear to the brain is where this benign tumour is located.
8 Pituitary tumours
Pituitary tumours can start in or around the pituitary gland. This little gland is situated not far from the brain’s base. The majority of tumours that develop in or near the pituitary gland are benign. The pituitary gland itself can develop tumours. The brain tumour known as a craniopharyngioma develops close to the pituitary gland.
9 Other brain tumours.
In and around the brain, a wide variety of uncommon tumours can develop. Muscles, blood arteries, and connective tissue around the brain are possible sites for tumour initiation. The skull’s bones can develop tumours. The brain’s immune system cells that combat infection can give rise to malignant brain tumours. Primary central nervous system lymphoma is the term used to describe this form of brain cancer.
Depending on the size and location of the brain tumour, specific signs and symptoms may be present. The severity of the symptoms may also be influenced by the tumour grade, another term for the rate of growth of the brain tumour.
- Brain tumour-related general signs and symptoms may include:
- Headaches that occur more frequently and feel worse
- Headaches are occasionally referred to as migraines or tension headaches.
- vomiting or nauseous.
- Eye issues such as double vision, hazy vision, or losing vision to the sides of your field of view.
- losing sensation or motion in a leg or arm.
- Have balance issues.
- Speech issues.
- incredibly exhausted.
- confusion in routine issues.
- memory issues.
- having difficulty obeying simple instructions.
- seizures, particularly if there has never been a history of seizures.
Changes in personality or behaviour.
- Hearing issues.
- Vertigo is another name for dizziness or the sensation that the world is spinning.
- gaining weight and experiencing extreme hunger.
Symptoms of non-cancerous brain tumours typically appear gradually. Benign brain tumours are another name for non-cancerous brain tumours. They could produce minor symptoms that you initially don’t notice. Over the course of months or years, the symptoms could worsen.
The symptoms of cancerous brain tumours rapidly worsen. Malignant brain tumours and brain cancer are other names for cancerous brain tumours. They result in symptoms that appear out of nowhere. Within a few days or weeks, they deteriorate further.
Headaches from a brain tumour
The most typical symptom of brain tumours is headaches. About 50% of persons with brain tumours get headaches. If a developing brain tumour pushes on nearby healthy cells, headaches may result. Or a brain tumour may expand the brain, increasing head pressure and bringing on a headache.
Brain tumour-related headache discomfort frequently gets worse in the morning. But it’s possible at any time. Some people are awakened from sleep by headaches. When coughing or straining, headaches from brain tumours frequently become more painful. Most frequently, brain tumour patients describe their headache as feeling like a tension headache. Some claim that the headache is similar to a migraine.
Back of the head brain tumours might result in a headache and neck pain. The headache may feel like sinus pain or eye pain if the brain tumour is in the front of the head.
Symptoms of a brain tumour by location
The cerebrum is referred to as the brain’s major structure. Different symptoms of brain tumours in various areas of the cerebrum are possible.
1 the front of the brain is affected by brain tumours.
In the front of the brain are the frontal lobes. They command behaviour and thought. Brain tumours in the frontal lobe may affect one’s ability to walk and maintain balance. There could be personality changes, such as lack of interest in routine activities and forgetfulness. Family members may occasionally notice a change in the brain tumour patient.
2 In the midst of the brain tumours
The parietal lobes are in the upper middle part of the brain. They help process information about touch, taste, smell, vision and hearing. Parietal lobe brain tumours can cause problems related to the senses. Examples include vision problems and hearing problems.
3 In the back of the brain, brain tumours
In the back of the brain lie the occipital lobes. They regulate eyesight. Vision loss may result from occipital lobe brain tumours.
4 Located in the bottom portion of the brain, these tumours
On the sides of the brain are the temporal lobes. They process sensitive data and memory. Memory issues may be brought on by tumours in the temporal lobe. They might make someone have false perceptions of taste, smell, or sight. Sometimes the flavour or scent is disagreeable or strange.
When to see a doctor
If you have persistent symptoms that bother you, schedule a visit with your healthcare professional.
