Brain Tumor Headaches: What Are They?
As the name suggests, brain tumor headaches are headaches caused by a brain tumor. It is estimated that about 50% of patients who are diagnosed with a brain tumor have experienced headaches as a symptom.
This type of headache occurs as a result of an increase in intracranial pressure, or pressure in between the skull and brain tissue, caused by a tumor.
It’s also possible that the tumor itself is stretching the dura, or the covering of the brain. The dura has a bunch of nerve endings, so it is more receptive to pain. In contrast, the brain itself does not have any pain receptors, so it doesn’t feel anything.
A brain tumor can also apply pressure on the nerves as it grows larger, causing pain and a headache. People usually describe it as a constant feeling of heaviness or squeezing in your head, and gets worse at night or in the morning. However, it’s possible for it to be a sharp, stabbing pain as well.
Over time, the pain can also worsen. This happens if the tumor grows bigger, which causes the intracranial pressure to go up even more.
