• Diffuse astrocytoma: This is the most common type of grade 2 astrocytoma. These tumors have a relatively slow growth rate and tend to infiltrate the surrounding brain tissue, making them difficult to completely remove surgically.
• Fibrillary astrocytoma: This subtype is characterized by the presence of long, thin fibers within the tumor cells, which give the tumor a stringy appearance.
• Gemistocytic astrocytoma: These tumors have large, rounded cells with abundant cytoplasm, which can make them appear more aggressive than other grade 2 astrocytomas.
• Protoplasmic astrocytoma: This rare subtype is characterized by a high degree of cellular differentiation, meaning the tumor cells resemble normal astrocytes more closely than other astrocytoma subtypes.

Regardless of the specific subtype, grade 2 astrocytomas are generally characterized by a moderate degree of cellular proliferation, minimal nuclear atypia (abnormal cell appearance), and the absence of necrosis (cell death) or microvascular proliferation – features that distinguish them from higher-grade astrocytomas.

Symptoms and Warning Signs

Early detection of astrocytoma grade 2 is crucial, as it can help in timely diagnosis and treatment. The symptoms associated with this type of brain tumor can be varied and may depend on the location and size of the growth.
