What is a brain tumor?

You can't feel a brain tumor directly because the brain and skull have no nerve endings. The lack of nerve endings means that your brain can't sense pain. But when a tumor grows and starts to put pressure on nerves and blood vessels around the brain, in the skull, you may get a painful headache.
Very few headaches are signs of a brain tumor. Most have nothing to do with brain tumors. You can only feel some symptoms of a brain tumor in its later stages.
A brain tumor is an abnormal cell growth in the brain. Brain tumors get classified into more than 120 types. The type of brain tumor depends on which part of the brain it has affected. A tumor can grow anywhere in the brain. The brain is complex and delicate, so any tumor can be dangerous. Not every brain tumor is cancer. There are two types of tumors, benign (noncancerous) and malignant (cancerous).
Brain tumors are pretty rare. They occur in about 30 out of 100,000 adults. A brain tumor becomes dangerous when it grows and starts to put pressure on the adjacent parts of the brain. Such tumors can stop fluid movement in your brain, causing extra pressure in the skull. Some brain tumors can become cancerous and spread to other parts of the brain or spine.
Most brain tumors come to the brain from other parts of the body. Such a tumor is called a metastatic or secondary brain tumor. The secondary brain tumor is most common in individuals who have a history of cancer. Common types of cancers that can spread to the brain include:
If the tumor originates in the brain or the parts around the brain, it's referred to as a primary brain tumor. Such tumors develop when a normal brain cell mutates and continues to grow into a tumor. Some examples of primary brain tumors are:
- Meningiomas
- Germ cell tumors
- Gliomas
- Pituitary adenomas
- Acoustic neuromas
- Medulloblastomas
- Craniopharyngiomas
Brain tumor headache
Headaches are the most common symptom of a brain tumor. But that doesn't mean you have a tumor just because you have a headache. Tumors usually show no signs in their early stages. Most people start getting symptoms of a tumor after it has reached its later stages.
In the case of a brain tumor, you may start getting the effects of pressure after the tumor has gotten too big. Headaches from a brain tumor are different from regular headaches.
Sometimes a headache from a brain tumor may be confused with the other types. While a migraine or a tension headache might be as painful, they are not life-threatening. Suppose you are mainly experiencing a headache with a consistent pattern. In that case, that's more of a migraine than a brain tumor. Headache from a brain tumor is usually accompanied by a number of other symptoms.
Main symptoms of a brain tumor headache
Your headache may be due to a brain tumor if you get:
- Frequent morning headaches as you wake up
- A headache that changes when you switch positions
- Frequent night headaches that wake you from sleep
- Frequent headaches that go on for days or even weeks
- Headaches that don't go away after taking standard pain medications like aspirin and ibuprofen
But remember that brain tumors are not the only condition that causes such pains. Consider looking out for headaches that frequently occur, in different types, and have changing severity. Such occurrences might be an indication of a brain tumor.
Also, consider talking to your doctor if you suddenly start getting frequent painful headaches that you are not used to getting before.
Other symptoms of brain tumor
Depending on the part of the brain that the tumor has developed, symptoms may vary. That's because different parts of the brain have specific functions. For instance, a tumor that develops at the back of the head may cause issues with balance, movement, and coordination. The cerebellum (the part of the brain associated with those functions) is found at the back. The size of the brain tumor and the speed it's growing also determines the symptoms you get.
The other common symptoms of brain tumors include:

While the exact cause of most brain tumors is unknown, some factors put you at higher risk:
- Age. The older you get, the higher your chances of developing a brain tumor. The majority of brain tumor cases affect adults between 85 and 89. But certain types of brain tumors occur more in children.
- Genetic inheritance. If you have a family history of conditions like tuberous sclerosis, neurofibromatosis type 1, neurofibromatosis type 2, and Turner syndrome, you are more likely to develop a brain tumor. Those conditions have been found to increase the risk of getting brain tumors.
- Radiation. Certain brain tumors affect individuals who have done head CT scans, X-rays, and radiotherapy. However, radiation only causes very few types of brain tumors.
Treatment of brain tumors
The management of brain tumors depends on factors like:
- The type of tumor
- The location
- Your health situation
- The size and how far it has spread
- The abnormality extent of the cells
Brain tumor treatment involves:
- Chemotherapy
- Radiotherapy
- Steroids
- Medications for symptoms management (i.e., painkillers)
- Surgery
Conclusion
Early detection of a brain tumor is vital for successfully treating the condition. The earlier you detect the tumor, the easier it will be to get rid of it. If you get some of the symptoms mentioned earlier and you suspect you might have a brain tumor, consider talking to your doctor about it for proper examination and screening.

Adrenocortical Carcinoma
Adrenocortical carcinoma (ACC) is rare cancer that affects the adrenal glands located on the top of the kidneys. Adrenal glands are one of the endocrine glands that produce cortisol, aldosterone and adrenaline hormones, which regulate the body's most important functions. Adrenal cancer or adrenocortical carcinoma commonly affects children (aged younger than five years) and middle-aged adults (aged 40 to 50 years). Women are at a higher risk than men.Adrenocortical Carcinoma in Children
Pediatric adrenocortical carcinoma is a rare type of cancer. It mostly occurs in the outer layer of the adrenal gland during the first five years of life or adolescence. An adrenocortical tumor is a cancer of the adrenal glands with a female gender predominance. Most tumors (9 out of 10) of the adrenal cortex in children are functioning tumors. They may cause signs or symptoms, depending on the type of hormone made by the tumor, whether it is excess androgen hormone or excess estrogen and cortisol.ataluren
Ataluren is an investigational drug used to delay disease progression in ambulatory patients with Duchenne muscular dystrophy (DMD), a progressive and fatal neuromuscular disease. The medication is not yet approved by the FDA and is not available in the U.S. Common side effects of ataluren include headache, nausea, vomiting, diarrhea, upper abdominal pain, gas (flatulence), abdominal discomfort, constipation, decrease in appetite, increase in cholesterol and triglyceride levels in blood, fever (pyrexia), ear infection, red rash (erythematous rash), feeling unwell (malaise), weight loss, high blood pressure (hypertension), and others.Brain Cancer
Cancers that form from brain tissue are called primary brain tumors. Brain tumors may be malignant (brain cancer) or benign. Certain risk factors, such as working in an oil refinery, as a chemist, or embalmer, increase the likelihood of developing brain cancer. Symptoms include headaches, weakness, seizures, difficulty walking, blurry vision, nausea,vomiting, and changes in speech, memory, or personality. Treatment may involve surgery, radiation therapy, or chemotherapy.Brain Cancer: Tumor Signs, Symptoms, and Treatment

Brain damage, also known as brain injury or neurological injury, is an injury to the brain that affects its ability to function properly. There are several tests used to detect brain damage, including medical history, physical examination, neurological examination, neuroimaging, neuropsychological testing, and other specialized tests. Brain damage can be subtle and may not always be detectable. Sometimes the effects of brain damage may not become apparent until later in life.Is GCT Cancerous?
Giant cell tumors (GCTs) are benign (noncancerous) tumors that most commonly occur in the bones of the arms and legs. These tumors are also called osteoblastoma or giant cell reparative granuloma. They can cause problems if they grow or spread to other parts of the body. In some cases, GCTs may recur after treatment, and there is a small risk of GCTs transforming into cancerous tumors.Is TGCT a Cancer?
Any joint can develop tenosynovial giant cell tumors (TGCTs). TGCTs are not cancerous but can grow and damage surrounding tissues or structures. Symptoms may include decreased movement or pain in the affected joint and a locking or catching sensation when moving the joint. Although it is not a fatal disease, TGCT can cause persistent discomfort and a negative influence on the quality of life.What Are the Signs of Dying From Brain Cancer?
