What are Seizures?
Seizures are sudden, uncontrolled electrical disturbances in the brain that can cause a variety of physical and mental symptoms. They can be a symptom of many different underlying conditions, including cancer.
In individuals with cancer, seizures can be caused by a number of factors, such as a tumor pressing on the brain, chemotherapy, or radiation therapy. Additionally, some anti-cancer medications can increase the risk of seizures.
There are many different types of seizures, each with their own unique set of symptoms. The most common types of seizures that cancer patients may experience include:
| Type of Seizure | Description |
|---|---|
| Partial seizure | A seizure that occurs in a specific part of the brain, causing localized symptoms such as twitching or numbness in one area of the body. |
| Generalized seizure | A seizure that affects the entire brain, causing loss of consciousness and widespread muscle spasms. |
| Absence seizure | A type of generalized seizure that presents as a brief loss of consciousness, usually lasting only a few seconds. |
What are the Symptoms of Seizures in Cancer Patients?
The symptoms of seizures in cancer patients can vary widely depending on the type of seizure and the underlying cause. Some common symptoms include:
- Loss of consciousness
- Jerking or twitching of muscles
- Staring spells
- Confusion or disorientation
- Changes in sensation, such as tingling or numbness
If you experience any of these symptoms, it is essential to seek medical attention immediately.
Types of Cancer-Related Seizures
Seizures that occur in cancer patients can be classified into different types, each with its own underlying cause. Here are some of the most common types:
| Type of Seizure | Underlying Cause |

| Generalized seizures | Caused by abnormal electrical activity throughout the brain |
| Absence seizures | Often seen in patients with gliomas or other brain tumors, characterized by brief lapses in consciousness and staring spells |
| Myoclonic seizures | Characterized by brief, involuntary muscle spasms, often seen in patients with brain metastases or other tumors that have spread to the brain |
Cancer-related seizures can also occur as a result of underlying neurological conditions, such as epilepsy or stroke. In addition, certain cancer treatments, such as chemotherapy and radiation therapy, may increase the risk of seizures.
Types of Cancer-Related Seizures
There are different types of seizures that may occur in cancer patients, including:
- Focal seizures
- Generalized seizures
- Absence seizures
- Myoclonic seizures
These seizures can be caused by changes in electrical activity in a particular area of the brain, a consequence of underlying neurological conditions, or as a side effect of cancer treatments such as chemotherapy or radiation therapy.
How Cancer Causes Seizures
Seizures in cancer patients can be caused by a number of different factors. In some cases, seizures may be caused by the tumor itself, particularly if it is located in the brain. Seizures may also be caused by inflammation in the brain caused by the cancer or its treatment.
Cancer treatments such as chemotherapy and radiation therapy may also increase the risk of seizures in some patients. Additionally, some cancer patients may have pre-existing neurological conditions that increase their risk of seizures.
Some types of cancer, such as lung, breast, and colon cancer, may be more likely to cause seizures than others. The risk of seizures may also increase as the cancer progresses or spreads to other parts of the body.
How Tumors Cause Seizures
Tumors in the brain can cause seizures by disrupting the normal electrical activity in the brain. As the tumor grows, it can put pressure on the surrounding tissue and interfere with the brain’s normal functions.
Additionally, tumors may cause inflammation and swelling in the brain, which can further disrupt the brain’s electrical activity and increase the risk of seizures.
How Cancer Treatment causes Seizures
Cancer treatments such as chemotherapy and radiation therapy can also increase the risk of seizures in some patients. Chemotherapy can cause damage to the brain tissue, and radiation therapy can cause inflammation and swelling in the brain.
In some cases, the combination of cancer treatment and pre-existing neurological conditions can also increase the risk of seizures in cancer patients.
It is important for cancer patients to discuss their risk of seizures with their healthcare provider and take steps to manage their symptoms and prevent complications.

Diagnosing Cancer-Related Seizures
Diagnosing cancer-related seizures requires a thorough evaluation by a healthcare professional. In addition to discussing your medical history and symptoms, your doctor may order several tests to confirm the presence of seizure activity.
Electroencephalogram (EEG)
An EEG is a noninvasive test that records electrical activity in the brain. It involves placing small electrodes on the scalp and monitoring brain waves while the patient is at rest and during certain activities. An abnormal EEG can indicate the presence of seizure activity and help doctors identify the type of seizures a patient is experiencing.
Magnetic Resonance Imaging (MRI)
An MRI uses powerful magnets and radio waves to create detailed images of the brain. This test can help identify any abnormalities in the brain that may be causing seizures, such as tumors or inflammation.
Blood Tests
Some blood tests may be ordered to rule out other potential causes of seizures, such as infections or metabolic imbalances.
It is important to follow your doctor’s instructions and attend all scheduled appointments to ensure an accurate diagnosis and appropriate treatment plan.
Treating Cancer-Related Seizures
Treatment for cancer-related seizures involves managing the underlying cause while also controlling the seizures themselves. The primary goal is to help patients maintain their quality of life and reduce the frequency and severity of seizures.
