Pro Tip 1/3Medical Specificity
Refers to a specific area so it's used with precision in medical contexts.
The MRI revealed a lesion in the cerebral cortex.
Pro Tip 2/3Severity Varies
'Lesion' doesn't specify severity; it can range from minor to serious.
Despite the lesion being benign, follow-up is necessary.
Pro Tip 3/3Not Always Visible
Some lesions are internal and not visible without medical imaging.
Her headache was caused by a lesion that only a CT scan could detect.

Our brain's ability to repair itself, known as brain plasticity, permits areas surrounding a brain lesion to take over some functions during the recovery process. Scientists have been conducting experiments using new forms of technology, which they believe may encourage brain plasticity in people with aphasia.

American Journalist
Sending Paris Hilton to jail for being the most loathed celeprosy lesion in the history of the species seems like a happening idea at first - forty-five days at Century Regional Detention Center is so the new thirty days at Promises Malibu! But it sets a dangerous precedent to jail celebs just because someone hates them.

English Author
Before MS moved in on me, I'd worked for seven years as a city lawyer, as the editor of a literary magazine, and before the age of 20, I'd also worked as a cadet journalist and as an assistant director in both film and TV. And then, after the lesions of MS, both on my spine and in my brain, I was the opposite of bionic.

Ben Fogle
English Writer

Maya Angelou
American Poet
One of my lungs is half gone, and the other half, because I smoked for years, has a lesion. So I can't swim anymore and had the swimming pool covered over. Now it's what I call the dance pavilion, and so I and my friends sit out and put music on and watch people dance.
Quote examples
Karen Duffy
American Actress
The lesion is in the area of my brain that is responsible for motor function, so I have continual chronic pain in my left arm from elbow to fingertips and the right side of my body from my ear to my breast area.

It turns out that the left temporal lobe, if there's a lesion there, will create hyper-religiosity. People become super-religious. They see demons and spirits everywhere. We think Joan of Arc may have had it.
