APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Astrocytomas are tumors which originates from astrocytes, and, in adult individuals, they are the most common brain tumors. In the US, about 15, 000 new astrocytomas are diagnosed every year. Males are slightly more affected than females, with a ratio of 1.3/1.

Detailed explanation-2: -glioma, plural gliomas or gliomata, a cancerous growth or tumour composed of cells derived from neuroglial tissue, the material that supports and protects nerve cells.

Detailed explanation-3: -The 5-year survival rate for children and teens up to age 19 with pilocytic astrocytoma is around 97%. For those with diffuse astrocytoma, the 5-year survival rate is around 81%. The survival rate for anaplastic astrocytoma is slightly over 28%. The grade of the astrocytoma affects survival rates.

Detailed explanation-4: -Astrocytoma is a type of cancer that can occur in the brain or spinal cord. It begins in cells called astrocytes that support nerve cells. Some astrocytomas grow very slowly and others can be aggressive cancers that grow quickly.
