About this Condition: Astrocytoma Grade 1 astrocytoma (non-infiltrating): Slow-growing tumors that typically do not expand into surrounding tissue. Grade 2 astrocytoma (low grade): Tumors that usually develop slowly, but can expand into surrounding tissue and grow more quickly over time.
What causes an astrocytoma?
Causes. The cause of most astrocytomas is not known. Researchers speculate that genetic and immunologic abnormalities, environmental factors (e.g., exposure to ultraviolet rays, certain chemicals, ionizing radiation), diet, stress, and/or other factors may play contributing roles in causing specific types of cancer.
What happens to the brain after a tumor is removed?
Swelling in the brain is expected after surgery, so recovery will take time and the benefits will not be immediately apparent. Steroids may be prescribed to your loved one to help with the swelling, but they may have their own set of side-effects (difficulty sleeping, sweating, over-eating, agitation).
What does astrocytomas do to the body?
Astrocytoma is a type of cancer that can form in the brain or spinal cord. Astrocytoma begins in cells called astrocytes that support nerve cells. Astrocytoma signs and symptoms depend on the location of your tumor. Astrocytomas that occur in the brain can cause seizures, headaches and nausea.
Is grade 3 astrocytoma a terminal?
Grade 1 and grade 2 astrocytomas grow slowly and are benign, meaning they're not cancerous. Grade 3 and grade 4 astrocytomas grow faster and are malignant, which means they're cancerous. An anaplastic astrocytoma is a grade 3 astrocytoma. While they're rare, they can be very serious if left untreated.
Can you survive a grade 2 astrocytoma?

Secondly, it offers the possibility to remove as much tumor is safely possible to relieve mass effect , reduce swelling and facilitate response to adjuvant therapies, when indicated. The decision whether to perform a simple biopsy or a full resection depends on multiple factors, but particularly on the clinical and medical conditions of the patient, as well as the predicted extent of resectability of the tumor.
How long does radiation treatment last for astrocytoma?
Radiotherapy: Radiation has been at the basis of treatment of astrocytomas for the past 50 years and it is extremely effective, at least for the first few months after treatment. Radiation, too, works by damaging DNA of the tumor cells, thus inducing their death. Under standard protocols, the treatment consists of small doses of radiation in the area of the tumor, 5 days a week for 6 weeks. Side effects are local hair loss (usually temporary), and fatigue. Long term side effects are necrosis of the brain around the treated region, and cognitive difficulties.

GBM can present either as a malignant progression from a previously existing lower grade astrocytoma (usually in 10% of cases) or originate directly as a grade 4 tumor (90% of cases).
What is the grade of astrocytoma?
According to the World Health Organization (WHO) classifications of brain tumors, astrocytomas range from grade 1 (most benign) to grade 4 (most malignant). This grading, which is made by analyzing the tumor cells under the microscope is based on the following features: 1) how abnormal the cells look like (atypia); 2) how much they grow (mitosis); 3) presence of newly made blood vessels within the tumor (vascular proliferation). This is further integrated by the analysis of tumor’s genetic features, i.e. the DNA analysis of the tumor cells. Generally, with the exception of grade 1 tumors, which are most common in the pediatric population, most astrocytomas affect patients older than 40. Also, the older the patient, the higher the chances of the astrocytoma to be of higher grade.

How to diagnose astrocytoma?
The diagnosis of astrocytoma is based on a thorough clinical evaluation, characteristic physical findings, a careful patient history, and specialized tests, such as blood tests, neuroimaging techniques, and/or other diagnostic studies. Neuroimaging techniques, such as computed tomography (CT) scanning and magnetic resonance imaging (MRI) of the brain assist in evaluating tumor size, location, and other factors. During CT scanning, a computer and x-rays are used to create cross-sectional images of certain tissue structures. MRI uses a magnetic field to create cross-sectional images of particular organs and bodily tissues. Examination of a sample of the tumor (biopsy) and microscopic examination of tumor cells is used to determine the tumor type and grade.
