Some may think medical marijuana for brain cancer is too good to be true. They may question if it does kill brain cancer cells. But while human clinical trials are still awaiting results, recent research is showing promise. Scientists and researchers for the past two decades have been testing the tumor-killing qualities of THC, and their findings may just surprise you.

What Side Effects and Symptoms of Brain Cancer Can Medical Marijuana Treat?

Cancer is a qualifying condition for the use of medical marijuana in a growing number of states. Cannabinoids in medical cannabis for brain cancer play a palliative intervention role against symptoms like:

Marijuana doctors also use Nabilone, which is a synthetic cannabinoid, and THC for weight loss and anorexia. These cannabinoids help improve mood when given in lower doses. CBD is anxiolytic (reduces anxiety) and works as an antidepressant.

What Is Brain Cancer?

Brain cancer is the overgrowth of brain cells that form tumors. Brain tumors often proliferate. They disrupt how your body functions, which could be life-threatening. But brain cancer isn’t common. In fact, the American Cancer Society states you have less than a one percent chance in your lifetime of developing brain cancer.

Types of Brain Cancer

Various brain tumor types exist. Some tumors in the brain are benign while others are malignant (cancerous). Primary brain tumors develop in your brain, while metastatic or secondary brain tumors develop in other body areas and spread to your brain.

  • Benign: Tumors are benign when they don’t spread to indirect areas or invade nearby tissue. Benign tumors aren’t as serious as malignant tumors. However, they can press on adjacent tissue, causing various problems in your brain.
  • Malignant: A malignant tumor may grow and spread rapidly and overpower your healthy cells as it takes up their blood, space and nutrients. Malignant tumors may also spread to other areas of your body. Tumor cells require nutrients and blood to survive, just like your other body cells.
  • Metastatic: Cancerous cells from tumors in other areas of the body make up metastatic brain tumors. Cells from another tumor spread to your brain in a metastasis process. These tumors are the most common type of brain cancer.
  • Primary: Certain brain cancers develop when a certain cell type transforms from its natural characteristics. These cells then begin growing and multiplying abnormally once transformed. As abnormal cells continue growing in your brain, they form a tumor. Doctors refer to brain tumors arising from this as primary brain tumors since they start in your brain.

Common types of primary brain tumors include:

  • Gliomas
  • Pituitary adenomas
  • Meningiomas
  • Medulloblastomas or primitive neuroectodermal tumors
  • Vestibular schwannomas

The glioma term includes:

  • Astrocytomas
  • Glioblastomas
  • Ependymomas
  • Oligodendrogliomas

Many of these get their name from the brain area or brain cell type they arise from.

History of Brain Cancer Treatment

Brain tumor surgery links centrally to the evolution of neurosurgery as a surgical specialty.  William Macewen performed the first successful removal of a brain tumor in a young female in 1879. In 1884, Mr. Rickman Godlee performed the first resection of a primary brain tumor.

During the tail end of the 19th century, we began seeing published works on the efforts to remove brain tumors. Since then, technological advancements have directly impacted the capability of neurosurgeons to remove tumors while decreasing the operation’s risk.

Symptoms of Brain Cancer

Brain cancer symptoms are plentiful and aren’t specific to brain tumors — other illnesses could be causing them. To be sure what’s causing your symptoms, you would require diagnostic testing. A couple of factors may cause symptoms:

  1. A tumor is invading or pressing on other areas of your brain, preventing them from functioning properly.
  2. Brain swelling is caused by the tumor or inflammation surrounding it.

While symptoms of metastatic and primary brain cancers are similar, the symptoms and signs of a brain tumor vary greatly depending on the tumor’s size, rate of growth and location in your brain.

brain cancer symptoms

Common brain tumor symptoms may include:

  • New onset or change in pattern of headaches
  • Unexplained nausea or vomiting
  • Gradual increase in frequency and severity of headaches
  • Trouble balancing
  • Problems with vision like double or blurred vision or loss of peripheral vision
  • Confusion in daily matters
  • Speech problems
  • Hearing problems
  • Behavior or personality changes
  • Seizures, particularly in those with no seizure history

Many individuals may experience a gradual onset of these symptoms, or they may miss them altogether. Some individuals act like they are having a stroke. If you notice any of the following symptoms, you should seek emergency medical help immediately:

  • Persistent and unexplained vomiting
  • Increased sleepiness or lethargy
  • Double vision or unexplained blurry vision, particularly on just one side
  • New type or pattern of headaches
  • New seizures

While many believe headaches are a common brain cancer symptom, they often don’t occur until later in the progression of your cancer. Your doctor may recommend you go to the hospital if you’re experiencing a significant headache pattern change. You’ll also want to pay attention to new symptoms such as:

  • Mental status changes like memory problems, excessive sleepiness or inability to concentrate
  • Seizures
  • Trouble expressing yourself or difficulty with speech
  • Difficulty walking or clumsiness
  • Personality or behavior changes
  • Nausea or vomiting (particularly in older or middle-aged individuals)
  • Sensory problems like visual changes
  • Sudden onset of fever, particularly after receiving chemo

If you know you have a brain tumor, any relatively rapid or sudden worsening of symptoms or occurrence of new symptoms should warrant a trip to the ER.

Effects of Brain Cancer

Those who have central nervous system neoplasms have a higher risk of a whole range of neurologic and medical complications with their condition or the treatments for their condition. These complications present a substantial cause of systemic and neurologic morbidity. Therefore, recognizing them and appropriately managing them is critical in optimizing your quality of life.

Brain tumors can harm important neurological pathways as well as encroach and compress brain tissue. Severe and occasionally life-threatening complications may occur with brain cancer such as:

  • A cerebral hernia, which is a progressive, life-threatening condition where portions of your brain force through a skull opening.
  • Restricted cerebrospinal fluid flow from the third ventricle, potentially leading to sudden death.
  • Hemorrhagic stroke producing unexpected loss of speech or vision, paralysis and unconsciousness.

Brain tumors can also cause mental effects. Your brain controls all aspects of who you are and what you feel and think. When you have a brain tumor, it can sometimes lead to a personality change like anxiety, confusion or mood swings.

Coping with a brain tumor is a difficult and long journey regardless of whether it’s terminal or chronic. No matter what type of tumor you have, how long your treatment is and what your quality of life will be after treatment, it’s quite possible you — and even your caregiver — can suffer from depression, according to the American Brain Tumor Association.

cancer depression

If you’re suffering from a brain tumor, you may end up experiencing different changes in your personality, such as:

  • Aggression or irritability
  • Apathy (lack of motivation and interest)
  • Disinhibition or loss of restraints or inhibitions causing you to behave in culturally or socially unacceptable ways
  • Anxiety
  • Depression
  • Forgetfulness and confusion
  • Difficulty organizing and planning
  • Mood swings
  • Trouble identifying your emotions or those of others

Even if you’ve never experienced depression in the past, developing a brain tumor can lead to it. On top of you feeling sad from receiving bad news, the tumor and its treatment can cause depression. And, the tumor may alter both your personality and mood depending on where it rests. Surgery, chemotherapy and other types of treatment impact your brain’s chemistry and neurological function, which often triggers depression too.

Brain Cancer Statistics

According to estimates by the American Cancer Society, brain tumors in the U.S. in 2018 for both children and adults will have the following progression:

  • Doctors will diagnose around 23,880 malignant brain tumors— 10,160 in females and 13,720 in males.
  • Around 16,830 individuals with brain tumors will die — 7,340 females and 9,490 males.
  • Overall, the risk of anyone developing a malignant brain tumor in their lifetime is and will remain less than one percent.

Current Treatments Available for Brain Cancer and Their Side Effects

Brain tumor treatments depend on various factors, including your:

  • General health
  • Age
  • Tumor characteristics like type, size and location

Some treatment options for brain cancer may include:

Brain Cancer Surgery

Many individuals with brain tumors end up having surgery. The surgeon performs this operation to verify you do have a tumor and remove it if you do. If the surgeon can’t remove the tumor, they’ll take a sample of it to determine its type. Sometimes — usually with benign tumors — just surgically removing the tumor will cure your symptoms.

With any surgery, issues like bleeding and infection can occur. Other risks you may face will depend on where in your brain the tumor is. For example, you may be at risk of vision loss if the surgeon is operating on a tumor near the nerves connected to your eyes.


With brain cancer, your doctor will administer certain medications with chemotherapy in them to kill tumor cells. You’ll take chemo drugs either by mouth or intravenously. Temodar (temozolomide) is the most common chemo drug for treating brain tumors, and it’s taken orally.

Side effects of chemotherapy depend on the dose and type of medication you receive but usually include hair loss, nausea and vomiting.

Radiation Therapy

During radiation therapy, the doctor uses high-energy beams like protons or X-rays to kill tumor cells. They may use external beam radiation where they target the radiation outside your body or, in rarer cases, brachytherapy where they target your brain tumor by placing the radiation inside your body.

Radiation therapy side effects will depend on the dose and type of radiation you receive. Common side effects experienced either during or right after therapy may include:

  • Headaches
  • Fatigue
  • Scalp irritation
  • Memory loss

Targeted Drug Therapy

This therapy focuses on certain cancer cell abnormalities. Targeted drug therapy blocks these abnormalities and causes the cancer cells to die. Different targeted therapy medications are available for different brain tumors.

Rehabilitation After Treatment

Since a brain tumor can develop in the areas of your brain that control your speech, motor skills, thinking and vision, you may require rehabilitation during your recovery. Types of rehabilitation you may require include:

  • Occupational therapy to get you back to your regular, everyday routine.
  • Physical therapy to assist you in regaining your lost muscle strength and motor skills.
  • Speech therapy to help with speech difficulties.
  • Tutoring to help school-aged kids with changes in their thinking and memory.

Once your physician diagnoses your brain tumor, you’ll need to keep all appointments with your doctor and any other referred specialists. When you have brain cancer, you could be at an increased risk of various other medical issues, potential worsening of your symptoms or recurrence of cancer.

How/Why Marijuana Can Be an Effective Treatment for Brain Cancer

One of the most frightening cancers to face is brain cancer, and one of the most aggressive forms of brain cancer is a malignant glioma. With limited options available for patients with this type of cancer, the treatment of gliomas is the subject of quite a few marijuana-based research studies.

In 2001, the Department of Biochemistry and Molecular Biology at Complutense University in Madrid explored using cannabinoids to inhibit the growth of gliomas.

By selectively activating the CB2 endocannabinoid receptor, researchers found they could signal cell death in the gliomas. This strategy allowed for the therapeutic benefits of cannabis without the psychotropic side effects experienced when marijuana is smoked or ingested using other methods.

cannaboids cancer cells

Growing research shows specific cannabinoids affect brain tumors positively in several ways. Here are a few:

  1. Cannabinoids could kill cancer cells. They induce apoptosis — natural programmed cell death in multicellular organisms — in glioma cells.
  2. Cannabinoids may hinder the vascular endothelial growth factor (VEGF) pathway, which plays a significant role in your tumor’s capability to make new blood vessels. These vessels are needed for the tumor to feed itself with nutrients and oxygen while eliminating waste products from itself.
  3. CBD might also hinder brain tumor growth, according to 2013 research by the University of Camerino — Italy’s Department of Experimental Medicine.
