Types of Brain Tumors in Young Adults
A brain tumor is a mass or growth of abnormal cells in the brain. It can be benign (noncancerous) or malignant (cancerous). Most brain tumors start in other parts of the body and spread to the brain, a condition called metastatic brain cancer. The most common type of metastatic brain cancer is breast cancer.
Brain tumors can also start in the brain. Brain tumors can occur at any age but most commonly affect people over 60. also is one type of brain tumor in young adults.
There are many types of brain tumors. The type of brain tumor depends on its location in the brain and the type of cell involved.
Most brain tumors are benign, which means they are not cancerous. Benign brain tumors can still be severe and cause symptoms because they grow and press on sensitive areas in the brain.
Malignant brain tumors are cancerous and can spread to other parts of the body. Malignant brain tumors are more likely to come back after treatment than benign tumors.
Brain tumors can cause a wide variety of symptoms, depending on the tumor's location. Common signs of brain tumors in adults include headache, seizures, nausea and vomiting, vision problems, memory problems, difficulty speaking or understanding speech, difficulty swallowing, weakness, or paralysis.
Types of Brain Tumors in Young Adults
There are many types of brain tumors in young adults and elders.
1) Astrocytomas: These tumors, which are the most common type of brain tumor, are particularly prevalent in young adults. They arise from star-shaped glial cells called astrocytes. There are four main types of astrocytomas: diffuse astrocytoma, anaplastic astrocytoma, glioblastoma, and brainstem glioma.
2) Meningiomas: These tumors develop in the meninges, the thin layer of tissue covering the brain and spinal cord. They are usually benign, which can provide some reassurance to those diagnosed with this type of brain tumor. They are another of the most common primary types of brain tumors in adults.
3) Medulloblastomas: These tumors develop in the cerebellum, the part of the brain that controls balance and coordination. They are the most common type of brain tumor in children.
4) Schwannomatosis: This rare type of tumor develops on the nerves that supply feeling to the skin.
5) Ependymomas: These tumors develop on the ependymal cells, which line the brain's ventricles (fluid-filled cavities). There are three main types of ependymoma: subependymoma, myxopapillary ependymoma, and clear cell ependymoma.
6) Oligodendrogliomas: These tumors arise from oligodendrocytes, which are cells that make up the myelin sheath (a fatty covering) that surrounds and protects nerve cells.
7) Choroid plexus papillomas: These tumors develop in the choroid plexus, a network of blood vessels and supportive tissue in the brain's ventricles. They are usually benign tumors.
8) Craniopharyngiomas: These tumors develop near the pituitary gland, a small endocrine gland at the base of the brain that regulates hormone production. Craniopharyngiomas are usually benign tumors.
9) Germ cell tumors: These tumors develop from germ cells, which are the cells that give rise to sperm or eggs. Germ cell tumors can be either benign or cancerous.
Causes of Brain Cancer and Risk Factors
The exact cause of brain cancer is unknown. However, several risk factors are associated with an increased risk of developing brain cancer, including:
- Age: The risk of brain cancer increases with age. Most diagnosed tumors are people over the age of 60.
- Gender: Brain cancer is more common in men than women.
- Family history: A family member with brain cancer increases the risk of developing the disease.
- Radiation exposure: People exposed to ionizing radiation (such as X-rays or radiation therapy) have an increased risk of developing brain cancer.
- Exposure to certain chemicals: People exposed to certain chemicals, such as vinyl chloride or pesticides, have an increased risk of developing brain cancer.
- Immune system problems: People with weakened immune systems (such as those with HIV/AIDS or who have had an organ transplant) have an increased risk of developing brain cancer.
- Previous cancer diagnosis: People diagnosed with another type of cancer are at an increased risk of developing brain cancer.
Diagnosing Brain Cancer
If a person has symptoms potentially caused by brain cancer, their doctor will likely order one or more of the following tests:
Imaging tests: These tests help create pictures of the inside of the body. Standard imaging tests used to diagnose brain cancer include:
- Computed tomography (CT) scans.
- Magnetic resonance imaging (MRI) scans.
- Positron emission tomography (PET) scans.
A biopsy is a procedure in which a small tissue sample is removed from the body and examined for cancer cells. A doctor can perform a biopsy using various methods, including surgery, needle, and endoscopic.
The cerebrospinal fluid test involves removing a small sample of cerebrospinal fluid (the fluid surrounding the brain and spinal cord) and testing it for cancer cells.
Neurological exam: This is a physical exam of the nervous system, including the brain, spinal cord, and nerves. During a neurological exam, the doctor will test a patient's vision, hearing, balance, coordination, and strength.
Neuropsychological testing: This cognitive testing assesses thinking, memory, and behavior. It can determine how a person's brain tumor affects their mental abilities.
Signs of Brain Cancer in Adults and Complications
One of the most common symptoms of brain cancer is a headache. The headache usually worsens in the morning and improves as the day continues. Other symptoms of brain cancer include:
- Seizures
- Nausea
- Vomiting
- Vision problems
- Memory problems
- Difficulty speaking or understanding speech
- Difficulty swallowing
- Weakness or paralysis
If a person experiences any of these symptoms of brain cancer, it is essential to see a doctor to diagnose and treat the cause.
Brain cancer can cause several complications, such as:
- Brain cancer can damage the brain, leading to problems with thinking, feeling, and controlling the body.
- Seizures are a common complication of brain cancer. Seizures happen when there is abnormal electrical activity in the brain.
- Brain cancer can cause the brain to swell. This swelling can lead to increased pressure inside the skull, which can be dangerous.
While brain cancer can be severe, with early diagnosis and treatment, many people with brain cancer live long and healthy lives.
Treatment and Prevention for Brain Tumors
The treatment for brain tumors depends on the type of tumor, its location, and the person's age and overall health. Treatment options include surgery, radiation therapy, and chemotherapy.
- Surgery is the most common treatment for brain tumors. The type of surgery performed depends on the size and location of the tumor. In some cases, a craniotomy (a surgery where part of the skull gets removed to access the brain) is necessary.
- Radiation therapy uses high-energy beams, such as X-rays or protons, to kill cancer cells. Radiation therapy can be given externally (from a machine outside the body) or internally (from a small device placed inside the body).
- Chemotherapy is a type of cancer treatment that uses drugs to kill cancer cells. Chemotherapy can be given intravenously (through a vein) or orally (by mouth).
- Targeted therapy is a type of cancer treatment that targets specific molecules involved in the growth and spread of cancer cells. Targeted therapy drugs usually get administered intravenously.
Treatment for brain tumors may also involve clinical trials, which are research studies that test new treatments in humans.
People with brain tumors may also receive palliative care, which is caring to relieve symptoms and improve quality of life without treating the underlying disease.
There is no sure way to prevent brain tumors. However, some things may help lower the risk of developing a brain tumor, such as:
- Not Smoking: Smoking is a risk factor for brain tumors. Quitting smoking can help reduce the risk of developing a brain tumor.
- Wearing sunscreen: ultraviolet (UV) radiation from the sun can damage DNA and increase the risk of developing a brain tumor. Wearing sunscreen with an SPF of 30 or higher can help protect against UV damage.
- Avoiding exposure to harmful chemicals: Certain chemicals, such as benzene, can increase the risk of developing a brain tumor. Preventing exposure to these chemicals can help reduce the risk.
- Getting vaccinated: There is a vaccine for the human papillomavirus (HPV), a risk factor for brain tumors. The HPV vaccine can help protect against this virus.
- Eating a healthy diet: Eating a diet high in fruits and vegetables and low in processed foods may help reduce the risk of developing a brain tumor.
Exercising regularly: Regular exercise has many health benefits, including reducing the risk of developing a brain tumor.
- Maintaining a healthy weight: Being overweight or obese is a risk factor for many diseases, including brain tumors. Maintaining a healthy weight can help reduce the development of a brain tumor.
- Regular checkups are not just routine visits. They are your best defense against cancer for early diagnosis when it's most treatable.
- Checking for family history of cancer: Having a family member with cancer can increase the risk of developing cancer oneself, and knowing a family history of cancer can help people make informed decisions about their health.
- These lifestyle changes can help reduce the risk of developing many types of cancer, not just brain tumors. Adopting these healthy habits may also help improve the overall quality of life.
CLL is a type of leukemia that affects white blood cells, making it harder for the body to fight infections. It often goes unnoticed in its early stages, but symptoms like fatigue, weight loss, and enlarged lymph nodes may appear as it progresses.
