A research presentation put forth during the fifty-second yearly conference of AAPM (Association of Physicists in Medicine) shows that kids with brain cancer undergoing radiation therapy (X-ray beams focused for killing malignant cells and shrivelling tumors) might be benefited by a technology termed as ‘IMAT’ or intensity modulated arc therapy. Intensity modulated arc therapy method is reliant on novel attributes of the newest generation of X-ray treatment device which provide X ray sources in continually rotating varied directions encircling the patient at the time of therapy. This technique helps to increase directions from which the X-ray beams are coming from. The research that was carried out by physical scientists from the St. Jude Children’s Hospital located in Memphis Tennessee  [...]

Findings of a latest study have revealed one method that gliomas –a lethal form of brain tumor could dodge medicines directed at hindering a crucial cell signalling protein, EGFR (epidermal growth factor receptor) which is fundamental for tumor development. In an interrelated discovery, they additionally established that a predominant EGFR mutation is significant not just in initiating the tumor, but for its continual augmentation or even for their continuance. These findings offer both novel percipiency into behavioural pattern of gliomas alongside prospective novel medicine targets and therapy approaches. The outcomes indicate that EGFR being expressed is crucial to tumor growth and researchers have shown for the foremost instance that there are means which tumors employ for circumventing  [...]

Not all kinds of brain tumors are known to cause symptoms with few like the tumors of the pituitary gland are detected largely subsequent to demise. Symptoms of brain tumor are copious and not specifically occurring due to brain tumors, which mean that they could also be the outcome of several other ailments. The sole means to ascertaining the precise reasons for the symptoms is undergoing diagnostic testing. The symptoms arise due to the pressure caused by the tumor or infringing on other areas of the body and hampering their normal functioning. Few of the symptoms occur due to the swelling in the brain because of the tumor or neighbouring inflammation. The signs of primary and metastatic brain cancers are analogous. The below stated signs of brain tumor are most prevalent: Headaches. Feeling  [...]

Researchers from the Duke University have deciphered the way in which stem cells present in the malignant brain cancer glioma could most aptly defend against radiation therapy. By employing a drug for blocking a certain signalling pathway in such cancer stem cells, they could annihilate greater numbers of glioma cells with radiation in a lab trial. The research work endeavoured at building off the previous research that revealed the greater resistance of cancer stem cells to the effects of radiation therapy in comparison to the other cancer cells. The Duke researchers recognized a well-known signalling pathway known as Notch as the possible cause for the enhanced resistance. Notch additionally operated in healthy stem cells where it is vital for inter cell communication that manages cell proliferation  [...]

Researchers from the HHMI or Howard Hughes Medical Institute have detected a novel factor that is indispensable for the development of several kinds of medulloblastoma – the prevalent form of malignant childhood brain cancer. HHMI researcher Huda Y. Zoghbi and associates from Baylor College Of Medicine averted development of medulloblastoma among mice by impeding the manufacture of the Atoh1 protein in vulnerable brain cells. The findings of the research team were cited in the 4th December 2009 edition of ‘Science’ indicate that Atoh1 might be a novel target in treating medulloblastoma. Zoghbi explicated that they didn’t have the faintest clue about the significance of the Atoh1 gene when they carried out its cloning way back in 1996. Presently it is known that it is important for several  [...]

Brain tumors in young children shed a protracted gloom on its survivors. The preliminary study delving into the permanent effect of these tumors – the highly prevalent solid tumours in infancy – reveals that those managing to survive them have continual cognitive issues. Also when such survivors were evaluated against their siblings and survivors of other cancer forms; they had inferior levels of learning, job standing and pay packets. This startling revelation was part of a report that was circulated by the American Psychological Association. The study appearing in the November edition of Neuropsychology states that with the plausible risks confronting brain or central nervous system (CNS) survivors, programs for supporting their trouble-free shift to self-sufficient adulthood are  [...]

Cancers of the human brain are nothing but anomalous cell growths in the brain. Though such growths are widely known as brain tumors, not all of them are cancer. Cancer is the word set aside for malignant tumors. The growth and spread of malignant tumors is quite aggressive, that tends to overpower normal cells by occupying their location, blood and nutrients. (tumor cells have requirements of blood and nutrients quite analogous to all cells present in the body.) Benign tumors are those that do not proliferate belligerently. Generally, a benign tumor is less grave as compared to a malignant tumor, however it does lead to several problems in the brain. Primary Brain Cancers The brain comprises of several kinds of cells. Few of the brain cancers occur due to the transformation of one kind  [...]
