Concern) Brain tumor

My younger sibling has a tumor found in their brain.

Fortunately, it's not malignant, but they say a procedure involving inserting a device through the nose to remove it is necessary.

I'm worried that something like this might develop again in the brain area, as they say it can occur due to stress, and I'm concerned whether removing it will completely cure it.

My head keeps hurting and I can't see well, so I went to check and this is what I found.

Everyone, please take good care of your health.
