My cousin is having brain tumor ..she had gamma knife treatment..she used to have severe headaches(like brain is pumping)now she is having breathing problem..and at a stage she stopped breathing then we pressured her chest then she was breathing again...when we took her to doctor they said that that due to brain pumping the pumping is going to diaphragm and there by she is having breathing problem..
The breathing is controlled by the brain. Sometimes due to increase of the pressure in the brain can cause breathing problems, sometimes it will be dangerous also. The other reason to exclude is tumor spread to the lungs. The treatment will be directed towards the cause. Raised pressure in the brain is due to swelling of the brain, by accumulation of the liquid(edema), it can be treated by Chat Doctor.
