Oncological neurosurgery
What is oncological neurosurgery?
The presence of a brain tumor is a diagnosis that brings uncertainty and many questions. In these moments, it is essential to rely on an experienced neurosurgeon—someone with solid technical knowledge, a humanized approach, and the ability to coordinate care with other medical specialties.
Oncological neurosurgery is the area dedicated to the treatment of brain tumors, whether primary (originating in brain tissues) or secondary (metastases from tumors in other organs). The goal is to remove or reduce the lesion, preserve neurological functions, and ensure a better quality of life.
As a neurosurgeon, I focus on individualized surgical planning and a multidisciplinary approach in partnership with oncologists and endocrinologists.
Common symptoms of brain tumors
Brain tumors can grow silently. In other cases, symptoms may appear suddenly or be mistaken for everyday issues. Pay attention to these warning signs:
Persistent headaches, especially upon waking
Nausea and vomiting without a clear cause
Seizures with no previous history
Weakness or loss of sensitivity on one side of the body
Speech or word comprehension difficulties
Visual changes not related to eye problems
Personality or behavior changes
Memory loss, confusion, or disorientation
Difficulty with coordination or balance
These symptoms require an evaluation with a specialist doctor.
Most common types of brain tumors
The most frequently treated tumors in oncological neurosurgery include:
Gliomas (including astrocytomas and glioblastomas)
Meningiomas
Schwannomas
Pituitary adenomas
Brain metastases
Each type requires a different surgical approach, depending on its aggressiveness, location, and the impact on brain structures.
The cancer patient journey
Treating brain cancer goes far beyond surgery. It is a journey that involves listening, strategy, and strong collaboration between doctor and patient.
Dr. André Mendonça’s approach includes:
Joint discussions of each case with oncologists and endocrinologists
Defining the best surgical timing
Assessing risks and benefits for each patient
Supporting the patient through postoperative recovery and, if necessary, rehabilitation
This comprehensive care model helps the patient understand all the stages and actively participate in decisions.
Oncological neurosurgery is a constantly evolving field. Technology, scientific research, and collaboration are always expanding the possibilities of treatment and cure.
If you’ve been diagnosed with a tumor or are experiencing symptoms that raise concerns, schedule a consultation. I can help you move forward with clarity and safety.

Frequently Asked Questions about Oncological Neurosurgery
Common symptoms include persistent headaches, seizures, weakness, and changes in speech, vision, or behavior. If you notice any of these signs, it’s important to consult a neurologist or neurosurgeon for early investigation and, if necessary, surgical intervention.
The surgery is performed by an experienced neurosurgeon, using high-precision imaging exams. The goal is to remove the tumor—or part of it—with minimal risk. In some cases, different techniques are used, such as intraoperative monitoring, to preserve vital functions.
Yes. With proper treatment and a multidisciplinary approach, many patients are able to resume their activities with a good quality of life. The neurosurgeon’s role is essential to ensure safety and achieve positive outcomes.
