Brain cancer can be a tricky subject to navigate, which is why we will explore the often-asked question: How serious is a brain tumor? Let’s break down and explore the complex world of brain tumors, shedding light on their seriousness, symptoms, types, and more. As a leader in our industry, we aim to empower you with the understanding needed to make informed decisions about this challenging medical condition. Let’s get started!
Understanding Brain Tumors
Brain tumors are a multifaceted medical condition that can vary significantly in terms of their seriousness. These abnormal growths of cells within the brain can be classified into two categories, benign (non-cancerous) or malignant (cancerous).
While most tumors can be put into these categories fairly quickly, some tumor types are more unpredictable and have a 50/50 chance of possibly being cancerous. Head to our blog, “Everything You Need to Know About Brain Cancer”, for more information on what brain tumors are and how they are caused.
Types of Brain Tumors
Generally Benign Brain Tumors (Non-Cancerous)
These tumors are typically slow-growing and have clear borders. They are not known to invade nearby tissues and are less likely to recur after treatment. Two of the most common benign brain tumors are Meningiomas and Pituitary Adenomas. Here are different types of tumors that typically fall into this category:
- Meningioma: Meningiomas are among the most common benign brain tumors, affecting women more often than men. They arise from the meninges, the protective membranes surrounding the brain under the skull. These tumors are typically slow-growing and may not cause symptoms for years. They can occasionally recur even after treatment.
- Pituitary Adenoma: Pituitary adenomas are benign tumors that develop in the pituitary gland, a small gland at the base of the brain. They often affect hormone production and can lead to vision problems as well. Since hormones can be affected, this leads to various symptoms depending on the hormone involved. Treatment may involve surgery, medication, or radiation therapy, depending on the tumor type and size.
- Craniopharyngioma: Craniopharyngiomas are benign tumors that develop near the pituitary gland and the hypothalamus. They can cause hormonal imbalances and pressure on nearby structures, leading to symptoms like headaches and vision problems. This tumor is commonly known to affect teenagers and children, with the occasional adult over the age of 50.
- Schwannoma: Schwannomas are benign tumors from the nerve connecting the ear to the brain. These tumors can cause hearing loss and affect the trigeminal nerve, causing facial pain. Middle-aged adults are most likely to develop this type of tumor.
- Nasopharyngeal Angiofibroma: Nasopharyngeal angiofibroma is a rare, non-cancerous tumor that typically occurs in adolescent boys. It originates in the back of the nasal cavity, near the throat. This tumor consists of blood vessels and fibrous tissue. It can be locally aggressive, meaning it may spread to areas around the nose, causing symptoms like nasal congestion and nosebleeds.
- Choroid Plexus Tumor: Choroid plexus tumors are rare, benign tumors that develop in the choroid plexus of the brain, which is responsible for cerebrospinal fluid (CSF) production. These tumors can lead to hydrocephalus, a buildup of cerebrospinal fluid, resulting in increased intracranial pressure. They most commonly affect young children.
- Dysembryoplastic Neuroepithelial Tumor: DNET is a rare, benign tumor that mainly affects children and young adults. They are slow-growing and are found in the tissues covering the brain and spinal cord. DNETs typically do not invade surrounding tissues, and their most common symptom is seizures.
- Neurofibroma: Neurofibromas are benign tumors that originate from nerve tissue. They are often associated with neurofibromatosis, a genetic disorder. These tumors can occur on or under the skin or within the nerves. They are typically slow-growing and painless.
- Hemangioblastoma: Hemangioblastomas are benign tumors that most commonly develop in the cerebellum, a part of the brain responsible for coordination. These tumors are highly vascular and consist of blood vessels, often causing symptoms like headaches and difficulty with coordination.
- Chondroma: Chondromas are slow-growing benign tumors that originate from cartilage tissue. They often develop in the skull or skull base but can be present in other parts of the body as well. These tumors are typically well-defined and do not invade nearby structures; however, they can lead to bone fractures or cause unwanted pressure on the brain.
- Giant Cell Tumor: As the name suggests, giant cell tumors are made up of large cells and can develop in the skull, legs, or arm bones. These tumors are composed of non-cancerous cells but can grow aggressively and cause harm to the bones.
- Osteoma: Osteomas are benign bone tumors that can develop in the skull or facial bones. They consist of mature bone tissue and tend to grow slowly, potentially causing problems with breathing, hearing, or vision.
Generally Malignant Brain Tumors (Cancerous)
These types of tumors are generally aggressive and often invade nearby tissue. They tend to recur after treatment and can spread to other parts of the central nervous system. While this is not always the case, tumors that fall into this category tend to have a poor prognosis. Here are different types of tumors that typically fall into this category:
- Chordoma: Chordomas are rare, slow-growing tumors that typically develop along the spine, particularly in the sacrum and base of the skull. These tumors tend to spread, invading nearby bones, and are often recurring.
- Chondrosarcoma: Chondrosarcomas are malignant tumors that originate in cartilage cells. They can occur in various parts of the body, including the skull base or face bones. These tumors tend to grow slowly but can be locally aggressive, often requiring surgical removal.
- Medulloblastoma: Medulloblastoma is a malignant brain tumor that primarily affects children between the ages of 5 and 9. It develops in the cerebellum, a part of the brain responsible for coordination. These tumors are fast-growing and can spread to other parts of the central nervous system.
- Olfactory Neuroblastoma: Olfactory neuroblastoma, also known as esthesioneuroblastoma, is a rare cancer that originates in the olfactory nerve in the nasal cavity. These tumors can affect a person's sense of smell and may cause symptoms like nasal congestion, nosebleeds, and difficulty breathing through their nose.
- Lymphoma: Brain lymphoma is a type of non-Hodgkin's lymphoma that affects the brain, spinal cord, or eyes. It typically occurs in people with compromised immune systems and can spread to other parts of the body. primary central nervous system lymphomas are commonly treated with chemotherapy and radiation.
- Gliosarcoma: Gliosarcoma is a rare and aggressive type of brain tumor that contains both glioblastoma and sarcoma components. These tumors tend to be highly invasive, resistant to therapy, and have a poor prognosis.
- Rhabdomyosarcoma: Rhabdomyosarcoma is a malignant tumor that typically arises in soft tissues and can also occur in the head and neck. These tumors develop from muscle cells and are more common in children.
- Paranasal Sinus Cancer: Paranasal sinus cancer refers to cancerous growths in the sinuses, which are air-filled spaces in the bones around the nose and eyes. Symptoms may include sinus congestion, facial pain, and changes in vision or smell.
- Atypical Teratoid/Rhabdoid Tumor (AT/RT): AT/RT is a rare, aggressive tumor that primarily affects children, usually appearing in the central nervous system. These tumors are fast-growing, have a high recurrence rate, and a poor prognosis.
How Serious is a Brain Tumor?
The overall severity highly depends on every personal case. However, in general, tumors that are classified as malignant tend to be more severe than those that are classified as benign.
