Optical glioma: what is it?

The optical glioma is a primary brain tumor, which originates from cells of the glia of the central nervous system (astrocytes, oligodendrocytes, ependymal cells and microglia cells) located near one of the two optic nerves. The optic nerves - constituting the 2nd pair of cranial nerves - transmit the visual information, coming from the ganglion cells of the retina (located on the bottom of the eyeball), to the visual cortex placed on the occipital lobe (brain region responsible for processing stimuli electric in visual images)

Why does radiation therapy have side effects?

2019

Usually aimed at treating tumors, radiotherapy involves exposing an area of the body to high-energy radiation. These high-energy radiations , also called ionizing radiations , create damage to the DNA of the cells they reach; damage that is permanent and lethal for cancer cells, but temporary and repairable for healthy cells. Th

How widespread is pancreatic cancer?

2019

Pancreatic cancer is one of the most deadly malignant tumors for humans. One of the main reasons for its high mortality is the fact that, often, in the initial phases it is asymptomatic, therefore difficult to recognize. According to recent estimates, the cases of pancreatic cancer diagnosed each year in the world, would be around 280000

Ependymoma: prognosis and survival

2019

The ependymoma is a primary brain tumor that originates from particular cells called ependymal cells . Ependymal cells are part of glia cells , therefore ependymomas fall into the category of gliomas , or neoplasms of the brain that derive from a genetic alteration of glia cells. An ependymoma can be benign - hence slow growing and with low infiltrative power - or malignant - that is, very fast growth and high infiltrative capacity

What are the risk factors for pancreatic cancer?

2019

The factors that favor the appearance of pancreatic cancer - a very serious malignancy - have been widely studied. A decisive influence on the development of the disease seems to have it: Cigarette smoke . This risk factor favors a long series of other malignant tumors, above all lung cancer. An unhealthy diet, rich in fat and meat

Oligoastrocytoma: what is it?

2019

The oligoastrocytoma is a brain tumor, which originates from two distinct cell lines called astrocytes and oligodendrocytes . Astrocytes and oligodendrocytes are glia cells , therefore oligoastrocytomas belong to the category of gliomas , or neoplasms of the brain that derive from a genetic alteration of glia cells

Brain tumors: some interesting numbers

2019

Primary brain tumors , or primary brain tumors or tumors of the central nervous system , are abnormal agglomerates of cells, formed and increased more or less suddenly in some region of the brain (ie brain, diencephalon, cerebellum and brainstem) or spinal cord. Fruit of genetic mutations of DNA whose causes are not yet known, brain tumors can be benign, slow-growing neoplasms or malignant neoplasms of a fast-growing nature
