What are the symptoms of early brain tumors?

 Sign 1: Headache in the morning.

The headache is often the heaviest when I wake up overnight, and it will gradually relieve after getting up. The general headache can be relieved in the afternoon.

Sign two: jet vomiting.

It usually occurs when the headache is severe, and the headache can be relieved after vomiting.

Sign three: vision loss, diplopia.

In the early stage, it may be transient amaurosis with short-term vision loss. As the disease progresses, it gradually becomes a continuous vision loss, and finally may be completely blind. Double vision: that is, the images of the two eyes cannot be overlapped, and any object is double-shadow. At first, diplopia can only appear when the eyeballs are gazing in a certain direction, and can later develop to appear in any direction. Finally, when the positions of the eyes on both sides are significantly asymmetrical, diplopia can be reduced or even disappear.
