A 5 cm brain tumor is considered a large tumor because it is much larger than most brain tumors, which generally range in size from 1-2 cm. A tumor of this size can cause a variety of health problems as it is pressing on vital brain structures. It can cause increased intracranial pressure, which can lead to headaches, nausea, and vomiting. If the tumor is pressing on the brainstem, it can cause a variety of neurological deficits, including difficulty walking, muscle weakness, and vision or speech problems. Depending on the type of tumor, it can also cause seizures, confusion, and memory problems.
Given the size of a 5 cm brain tumor, it is important to consult a doctor to determine the best course of treatment. Surgery is the most common form of treatment, but radiation and chemotherapy may also be necessary depending on the type of tumor. The prognosis for the patient will depend on the type of tumor, its location, and how it has been treated. In general, the larger the tumor, the more aggressive the treatment will need to be and the poorer the prognosis will be.
