Can a hard hit to the head cause a tumor?
As for brain cancer, there's good news: The most comprehensive (and long-term) study on the topic found little evidence that a traumatic brain injury could cause a brain tumor — and if the risk exists, it's extremely small.
Cancer myths
This is because either there is no evidence about them or it is less clear. In particular, there is no evidence that brain tumours are caused by a head injury or a bump on the head.
Injuries cannot cause cancer, but an injury may lead to finding cancer in the injured area. For example, a bone that is weak from a cancerous tumour is more likely to break – and treating the broken bone could lead to the discovery of the cancer.
How Does Your Brain Get Hurt? A hard blow to the head can shake your brain inside the skull. The result: bruises, broken blood vessels, or nerve damage to the brain. A hard hit that doesn't cause bleeding or an opening in your skull could be a closed brain injury.
Swelling under the skin (called a hematoma or “goose egg”) is usually a temporary symptom of head trauma. A goose egg can form in a hurry — the forehead is quick to swell because there are so many blood vessels just under the skin's surface.

Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.
Diagnosing a brain tumor usually involves a neurological exam, brain scans and a biopsy, if it can be done safely. A neurological exam may include a variety of tests to evaluate neurological functions such as balance, hearing, vision and reflexes.
Our search of the English literature revealed a few case reports of soft tissue tumors developing at the site of a previous traumatic injury [1-17]. Desmoid tumors, lipoma and lymphoma were among the tumors reportedly associated with such injuries.
Can you get a tumor from a bruise?
Sometimes an injury can cause a lump that's not cancer. This can be bruising or scar tissue that can form when the body naturally repairs itself. There's no evidence to suggest that these lumps increase the risk of cancer, but they may need treatment if they don't go away on their own.
Persons who suffer a severe brain injury may lose muscle strength, fine motor skills, speech, vision, hearing, or taste function, depending on the brain region involved and the severity of brain damage. Long- or short-term changes in personality or behavior may also occur.
Anyone who has just sustained an impact to the head should immediately seek emergency medical care by calling 911 or visiting an emergency room if they experience any of the following symptoms: Loss of consciousness. Inability to recognize people or places. Trouble with balance or walking.
“The most dangerous place to hit your head is on either side of your head, just above your ears. The skull is thinnest there, and there's an artery that can burst and cause direct bleeding in the brain.”
- Loss of consciousness (you blacked out)
- Extreme fatigue.
- Confusion.
- Seizures.
- Differences in speech, hearing, or vision.
- Weakness or numbness.
- Fluid draining from eyes, ears, or nose.
- Bruising around the eyes.
"Signs that should prompt you to seek medical advice usually develop in the first 24 hours after the injury, but rarely symptoms can occur as much as 72 hours after head trauma," Dr. Johnson explains. “So, it is important to watch for warning signs that may indicate a serious injury.”
If they become confused, unfocused or off-balance, they may not be able to seek help on their own. Most head injuries do not need any intervention, but if there is ever any doubt, get checked out.
Most head trauma only causes a scalp injury. The deep headache usually clears in 24 hours. The scalp pain at the site of impact may last 3 days. The swelling may take a week to go away.
Symptoms that accompany a brain tumor headache
double vision, blurred vision, or a loss of vision. increased pressure felt in the back of the head.
Magnetic resonance imaging (MRI) is commonly used to help diagnose brain tumors. Sometimes a dye is injected through a vein in your arm during your MRI study.
What does the start of a brain tumor feel like?
Some people with brain tumors experience general symptoms like headaches, seizures, and fatigue. Other symptoms can be more specific to the location of the tumor in the brain. Brain tumors can damage healthy tissue, press on healthy brain tissue, or cause pressure in the brain and negatively impact certain functions.
Benign (non-cancerous) brain tumours can usually be successfully removed with surgery and do not usually grow back. It often depends on whether the surgeon is able to safely remove all of the tumour. If there's some left, it can either be monitored with scans or treated with radiotherapy.
Generally speaking, a brain tumor can take several months or even years to develop. Glioblastomas are the most common and aggressive brain cancer. Their ability to grow undetected by the immune system makes them one of our primary examples.
They are often described as dull, "pressure-type" headaches, though some patients also experience sharp or "stabbing" pain. They can be localized to a specific area or generalized. They can be made worse with coughing, sneezing or straining.
Look carefully at your fingernails, palms, forearms (including the undersides), and upper arms. Examine the back, front and sides of your legs. Also look around your genital area and between your buttocks. Sit and closely examine your feet, including toenails, soles and the spaces between your toes.
An infection or abscess is perhaps the most common cause behind a mass that is mistaken for a tumor. In addition, cysts may arise from inflamed joints or tendons as a result of injury or degeneration. Inflammatory conditions, such as rheumatoid arthritis, can also result in soft tissue masses.
Cancerous lumps are usually hard, painless and immovable. Cysts or fatty lumps etc are usually slightly softer to touch and can move around.
Common symptoms of brain tumours include headaches, feeling or being sick and seizures (fits). These symptoms and the others listed below are often caused by other medical conditions. But if you have any of them, it's important to see your doctor.
Cancerous head lumps are usually hard and painless to the touch. In many cases, the mass appears spontaneously, then steadily grows in size.
In general, common symptoms of skull base tumors include: Headaches. Difficulty breathing. Altered sense of smell.
Can you get a permanent bump from hitting head?
Blunt head injury often causes an immediate lump of the scalp due to subcutaneous hematoma. The lump usually shrinks gradually and heals without intervention. On the contrary, a growing pulsatile lump of the scalp rarely occurs after blunt head injury.
- Headaches.
- Seizures or convulsions.
- Difficulty thinking, speaking or finding words.
- Personality or behavior changes.
- Weakness, numbness or paralysis in one part or one side of the body.
- Loss of balance, dizziness or unsteadiness.
- Loss of hearing.
- Vision changes.
“Headache is the hallmark symptom,” Dr. Daniels says, “but any sudden weakness or any headache associated with nausea and vomiting is suspicious. Increased clumsiness when walking or with the coordination of your hands and arms are also things we see.”
The 5-year survival rate for people in the United States with a cancerous brain or CNS tumor is almost 36%. The 10-year survival rate is almost 31%. Age is a factor in general survival rates after a cancerous brain or CNS tumor is diagnosed. The 5-year survival rate for people younger than age 15 is about 75%.
Mild traumatic brain injury may affect your brain cells temporarily. More-serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain. These injuries can result in long-term complications or death.
