Tahlia was diagnosed with a benign brain tumour attached to her optic nerve and near her brain stem, both high-risk areas for surgical removal. (rmhcwa.org.au)

Logan had what's called a midline posterior fossa tumor, causing moderate obstructive hydrocephalus. (stanfordchildrens.org)

In class, Ruhlin learned about parts of the ear, the importance of hearing aids and tumors like acoustic neuromas that can cause hearing loss. (auburn.edu)
Acoustic neuromas are rare, affecting only about three people in 100,000, but are risky because of their proximity to the brain stem. (auburn.edu)

From an analysis of the whole material, Dandy concludes that the symptomatology of tumors in the third ventricle is not particularly characteristic. (jamanetwork.com)

However, children and adolescents, the oldest adult age group, cases diagnosed with anaplastic ependymoma and/or tumour location in a brain site had lowest survival rates. (cdc.gov)

Frontal lobe: Tumors may contribute to poor reasoning, inappropriate social behavior, personality changes, poor planning, lower inhibition, and decreased production of speech (Broca's area). (wikipedia.org)

The cause of most brain tumors is unknown, though up to 4% of brain cancers may be caused by CT scan radiation. (wikipedia.org)
Exposure to radiation to the brain may also play a factor. (baptisthealth.net)
Common risk factors for brain tumors include hereditary causes, radiation exposure in the treatment of cancer, radiation due to atomic bombs, and genetic mutations. (ponea.com)
Now 7, Tahlia has undergone three craniotomies, five rounds of chemotherapy and recently completed six weeks of radiation, all to stop the growth of the tumour. (rmhcwa.org.au)
Tumour control is achieved by radiation-induced damage to DNA, which ultimately causes tumour cell death. (nature.com)
In vivo , however, lethal tumour doses are not always achievable because of radiation-induced morbidity in normal tissues. (nature.com)
To date, the most advanced photon beam delivery method is intensity-modulated (IM) radiation therapy (IMRT), which can deliver higher doses of radiotherapy to tumour targets while reducing the dose delivered to selected normal tissues. (nature.com)

In adults, this type of tumor is much less common. (actchealth.com)

Within the brainstem is the pons, a specialized area that serves as a major relay center between the brain and the bladder (see the image below). (medscape.com)
The pons relays afferent information from the bladder to higher brain centers, which in turn communicate with the periaqueductal gray matter, a relay station that collects higher brain center intput and processes this in order to signal the PMC to trigger or suppress the voiding reflex. (medscape.com)
The pons is a major relay center between the brain and the bladder. (medscape.com)
Usually the brain takes over the control of the pons, via the periaqueducatal gray matter, when children undergo toilet training. (medscape.com)
When the bladder becomes full, the stretch receptors of the detrusor muscle send a signal to the pons, which in turn notifies the brain. (medscape.com)

To carefully resect the tumor, Dr. Prolo used several advanced tools to ensure safe and accurate removal and to protect surrounding areas of Logan's brain, including his motor and sensory tracts and cranial nerves. (stanfordchildrens.org)

Only a small percentage of patients experiencing severe headaches suffer from brain tumors. (actchealth.com)
A tumor in the brain can put pressure on sensitive nerves and blood vessels, causing severe headaches. (actchealth.com)

Headaches as a result of raised intracranial pressure can be an early symptom of brain cancer. (wikipedia.org)
