Gradual loss of sensation
In some cases, there is also a loss of sensation on a given part of the body, and it becomes more pronounced as the tumor grows. As the tumor grows, these changes of sensation may extend to other regions of the body. This symptom is more common when the tumor is located near to the post central gyrus in the parietal lobe. This part of the brain is in charge of the sensation of touch and pressure throughout the body.
