Brain Tumor: Warning Signs, Risk Factors, and Advanced Treatment

Brain tumors don't present themselves plainly—sometimes symptoms are vague and can be misinterpreted as stress, a migraine, or simply tiredness until they become an issue of concern. The Neurology and Neurosurgery teams at Mahatma Gandhi Hospital (MGH), Jaipur, provide evaluation and treatment for patients with brain tumors, supported by specialist expertise, diagnostic imaging, and coordinated patient care.

This guide takes you through warning signs, causes, types, diagnosis, and the treatment options available today to ensure you know what to look for and when to take action.

What is a Brain Tumor?

A brain tumor is a growth of abnormal cells in the brain tissue and/or around the brain. Tumors can develop from cancer in the brain tissue (primary brain tumor) or cancer elsewhere in the body (secondary or metastatic brain tumor) spreading to the brain.

Not all brain tumors are malignant, and the severity of each case depends on the growth rate, location, and nature of the cells in the tumor.

Is a Brain Tumor Cancerous? Is Every Brain Tumor Cancer?

Cancer isn't the only type of brain tumor. Tumors can generally be classified as benign or malignant. Benign brain tumors are non-cancerous, but they can still cause significant symptoms or complications depending on their size and location. Many grow slowly, but some may require treatment if they press on important brain structures or cause neurological symptoms.

What Are the First Signs of a Brain Tumor?

Brain tumor symptoms depend on the size, location, and rate of growth of the tumor and may include the following:

• Recurrent or aggravating headaches, often more painful in the morning.
• Epilepsy, especially if the person has no history of it.
• Upset stomach or vomiting, for no known reason
• Blurring or loss of sight and/or hearing
• Gait disturbance and/or coordination problems.
• Arms or legs are weak or numb, usually on one side.
• Changes to personality or trouble focusing attention.
• Speech difficulties

How Do You Know If You Have a Brain Tumor?

There is no single characteristic symptom—the pattern is important. Symptoms of brain tumor concern are those that happen all at once, get worse, or don't improve after a person normally takes painkillers.

Can Headaches Be a Sign of a Brain Tumor?

Yes, but most of the headaches are not caused by a brain tumor. A headache associated with a tumor is usually not like a tension or migraine headache, as it may get worse in the morning, become worse with coughing or straining, and be accompanied by other neurologic symptoms, such as vision changes or nausea. Headaches without these symptoms are much more likely to be common, non-serious types.

Woman Brain Tumor Symptoms

The warning signs of brain tumors are generally similar in women and men. Persistent or unusual neurological symptoms, such as headaches, seizures, vision changes, weakness, balance problems, or changes in speech, should be medically evaluated rather than automatically attributed to stress or hormonal changes.

What causes a brain tumor?

In most cases, the cause of brain tumors is not known, but some risk factors are known.

The following are factors that increase the likelihood of a brain tumor developing.

• Age: Some types of tumors are more common in older children and adults.
• Hereditary: Individual susceptibility or genetic syndrome may increase the personal risk.
• Prior radiation therapy: Radiation exposure is a known risk factor, especially if it occurred during childhood.
• Immune system impairment:⁣ Some types of brain tumors are associated with an impaired immune system.
• Genetic syndromes: Neurofibromatosis or other syndromes are linked to an increased risk of tumors.

Although there is a continuing debate about lifestyle issues, such as diet or the use of mobile phones, so far there is no evidence that they directly cause cancer.

Types of Brain Tumors

Brain tumors can be classified into several general categories based upon their location and behavior:

• Gliomas: Develop from the glial cells that provide support to nerve function; some of the most common malignant forms of glioma are astrocytomas and glioblastomas.
• Glioblastomas: Aggressive malignant brain tumors that arise from glial cells, specifically astrocytic cells, within the brain.
• Tumors of the pituitary gland: Mostly non-cancerous and related to hormone production.
• Metastatic tumors: Tumors that have spread to the brain from another place in the body, for example, the lungs or breast.
• Medulloblastomas: Found in children in the cerebellum.

Brain Tumor Stages

Brain Tumor Grade and Classification

Brain tumors are generally classified according to their type, grade, and molecular characteristics rather than a conventional Stage I-IV system. The tumor grade provides information about how abnormal the cells look and how aggressively the tumor is likely to behave. These factors, along with the tumor's location and molecular profile, help doctors determine prognosis and treatment.

How is a brain tumor diagnosed?

A diagnosis of a brain tumor usually requires one or more of the following:

• Neurological examination: Checking for abnormalities in vision, hearing, balance, coordination, and reflexes.
• MRI and CT Imaging: Detailed scans that show the size, location, and characteristics of the tumor.
• Biopsy: A procedure in which a tissue sample is removed to determine if a tumor is benign or malignant and what type it is.
• PET scans: Occasionally, to evaluate tumor activity and exclude the possibility of secondary spread from a different site in the body.

Treatment for a brain tumor varies greatly depending on the type, grade, and location of the tumor, and an accurate diagnosis is crucial.

What's the Best Treatment for a Brain Tumor?

No one treatment is best, and treatment will vary based on the type of tumor, its size, location, and the overall health of the person. The most common treatments used for brain tumors are:

1. Brain tumor surgery: This may be the initial treatment for easily reached tumors, where the goal is to safely remove as much of the tumor as possible.
2. Radiation therapy: Used as a single treatment or following surgery to kill any cells that were left behind, especially when a tumor cannot be completely removed.
3. Chemotherapy for brain cancer: Sometimes combined with radiation for more serious types of malignant tumors and used for certain types.
4. Targeted therapy: Treats specific genetic or molecular characteristics of certain types of tumors.
5. Advanced treatment options: Techniques such as stereotactic radiosurgery and image-guided neuronavigational methods improve targeting and minimize healthy brain tissue damage.

Brain Tumor Operation: What to Expect

Pre-surgical imaging and planning are essential in brain tumor surgery to determine the exact location of the tumor in relation to other important brain structures. Modern neurosurgical techniques strive to achieve removal of the tumor with minimal disruption to healthy brain tissue and without significant risk of damage to brain structures. These techniques are designed to preserve as much healthy brain tissue as possible while removing as much tumor tissue as possible.

Brain Tumor After Removal: Recovery and Follow-Up

Recovery from brain tumor removal depends on the type, size, and location of the tumor; the extent of the surgery; and other factors. Depending on which brain functions were affected, many patients will need some time to rehabilitate, such as using physiotherapy or speech therapy. Regular imaging follow-up to check for recurrence, especially for malignant types of tumors.

Can a Brain Tumor Be Cured?

Certain types of brain tumors may be treated successfully, especially if they are benign and are caught in the early stages and completely removed. Malignant tumors are more difficult to manage and may not be completely treatable, but combination treatment can increase survival and quality of life. The response is largely influenced by the type, grade, and early treatment of the tumor.

So, what is the survival rate for a brain tumor?

The chances of survival range widely for each tumor type, grade, location, and early detection and treatment. Most benign tumors have a good prognosis, and malignant tumors are more likely to be difficult to treat. This means that any single statistic is not a very precise indicator, and diagnosis by a neuro-oncology specialist gives a much better idea of what is happening to you.

When to Go to the Doctor?

Seek immediate neurological or neurosurgical advice if you have new, worsening, or persistent headaches; if you have unexplained seizures; if you have sudden vision or balance problems; or if you notice changes in speech, memory, or personality. Early evaluation can facilitate early diagnosis and a broader array of effective treatments.
