“In September, Logan and I moved into a new apartment. Soon after, I began experiencing severe lower back pain. I thought I had a slipped disc. But weeks later, I started having nerve pain in my right thigh, followed by unbearable pain in my legs and back. A few months later, I was diagnosed with a rare form of brain cancer – diffuse midline glioma.”
What is Glioma?
Glioma is a type of tumor that occurs in the brain and spinal cord. It originates in the glial cells (also called neuroglia), which support and protect nerve cells in the central nervous system. While not all gliomas are cancerous, many can be life-threatening.
Gliomas usually form in the brain but can also occur in the spinal cord. Common types include astrocytoma, glioblastoma, oligodendroglioma, and mixed gliomas like oligoastrocytoma.
Symptoms of Glioma:
Headaches
Nausea or vomiting
Vision problems
Weakness
Seizures
Symptoms depend on the tumor’s size, location, and growth rate. Treatment typically involves surgery, radiation therapy, and chemotherapy, depending on the specific type and severity of the tumor.
Kelley Mack’s strength, grace, and spirit will continue to inspire many. She will be deeply missed.
