Can you feel the lump of brain tumor by touching the outer side of the head?

No, it is generally not possible to feel a brain tumor by touching the outer side of the head. Brain tumors are located within the skull, which is protected by the skull bones and layers of tissues. They do not directly protrude to the outer surface of the head where they can be felt through touch.

Brain tumors are typically diagnosed through medical imaging techniques such as CT scans, MRI scans, or PET scans. If you suspect you might have a brain tumor or are experiencing concerning symptoms, it's important to consult a medical professional for a proper diagnosis and appropriate medical guidance.
