Removal of tumor tissues helps decrease the pressure of the tumor on nearby parts of the brain. [17] The main goal of surgery is to remove as much as possible of the tumor mass while preserving normal brain function, and to relieve the symptoms caused by the tumor such as headache, nausea and vomiting.

Most brain tumors have higher ADC than normal brain tissues and doctors can match the observed ADC of the patient's brain tumor with a list of accepted ADC to identify tumor type. DWI is also useful for treatment and therapy purposes where changes in diffusion can be analyzed in response to drug, radiation, or gene therapy.
It is the most common cancer that begins within the brain and the second-most common brain tumor, after meningioma, which is benign in most cases. [6] [15] About 3 in 100,000 people develop the disease per year. [3] The average age at diagnosis is 64, and the disease occurs more commonly in males than females. [2] [3]
A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord.They are malignant but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumors, and 80 percent of all malignant brain tumors.
As is the case with most brain tumors, a major difficulty in treating DIPG is overcoming the blood–brain barrier. [20] [21] In the brain – unlike in other areas of the body, where substances can pass freely from the blood into the tissue – there is very little space between the cells lining the blood vessels.
Cancer in children is rare in the UK, with an average of 1,800 diagnoses every year but contributing to less than 1% of all cancer-related deaths. [76] Age is not a confounding factor in mortality from the disease in the UK. From 2014 to 2016, approximately 230 children died from cancer, with brain/CNS cancers being the most commonly fatal type.
Because the cancer usually attacks children under the age of 3, its victims are often unable to report the symptoms of a mass blocking their vision until it’s too late to treat with procedures ...
Pilocytic astrocytoma (and its variant pilomyxoid astrocytoma) is a brain tumor that occurs most commonly in children and young adults (in the first 20 years of life). They usually arise in the cerebellum, near the brainstem, in the hypothalamic region, or the optic chiasm, but they may occur in any area where astrocytes are present, including the cerebral hemispheres and the spinal cord.
