Joseph " Beau " Biden ’s late death from wit malignant neoplastic disease at age 46 highlight the mysteries of this rare yet often lethal physical body of cancer .
It ’s not clear what type of brain cancer Biden had , but in 2013 , he had a small lesion polish off from his brain , concord to The New York Times . Some politician guess Biden , son of Vice President Joe Biden and former lawyer general of Delaware , might be well enough to move for governor of Delaware in 2016 , but his health decline in recent weeks , The New York Times reported .

Brain Crab is a rare type of cancer , calculate for only about 1.4 per centum of all new Crab cases in the United States , according to the National Cancer Institute . Here are five fact about brain cancer :
There are many different type of brain tumour , and some type have low survival pace .
Einstein tumors occur when cells in the brain grow abnormally ( known as primary encephalon tumors ) , or when cancers spread from other voice of the body to the head ( known as metastatic brain tumors ) . TheJohns Hopkins School of Medicineestimates that there are more than 120 types of chief mind tumors .
Some genius tumor are benign , intend they are not made up of cancer cells . These tumour be given to acquire slowly , and do n’t often spread to other part of the nous or organic structure , but they can still be dangerous because they may agitate on head tissue paper as they farm , causing problem that can be disabling , harmonise to the American Cancer Society .
Malignant brain tumor , in direct contrast , grow more quick , and are more potential to be animation - threatening , according to the National Cancer Institute . In 2015 , there will be an estimated 22,850 unexampled typesetter’s case of malignant mentality tumors , and 15,320 deaths due to malignant brainpower tumor , in the United States . About a third of patients with malignant brain tumour survive for at least five years after their diagnosis , the NCI enounce . [ 10 Things You Did n’t Know About the Brain ]
One particularly aggressive form of brain malignant neoplastic disease is glioblastoma . Only about 6 percent of people with glioblastoma ages 45 to 54 , and 4 percentage of those ages 55 to 64 , survive for at least five years after their diagnosis , harmonise to the American Cancer Society .
But other types of brain neoplasm have in force forecast . More than 90 pct of people ages 20 to 44 who are diagnose with abenign character of head tumor call a meningioma , and 77 percent of those age 45 to 54 who are name with this type of tumor , survive for at least five years .
The case of head cancer is usually unknown .
One of the mysteries of Einstein cancer is what cause the disease . Most people with brain cancer do n’t have any known peril factors for the disease , according to the NCI .
But there are a few factor known to increase the risk of wit cancer . One factor is picture to a type of radiation call ionise radiation , which is used to do by certain cancers , although the development of brain genus Cancer from this case of radiation syndrome is rarified , consort to the ACS . Ionizing radiation therapy is also released during nuclear explosions .
In rare suit , brain Crab can take to the woods in families , mean a transmissible mutation is join with the genus Cancer .
brainiac tumors can occur at any old age .
Brain tumors can occur in both kid and adult . Such tumors are the second most common form of Crab in puerility , after leukemia , according to The Children ’s Hospital of Philadelphia .
In grownup , meningiomas and glioma ( the latter of which form from a character of brain mobile phone called glial cells ) are the most common brain tumors in adults , according to the National Institutes of Health .
Headaches are n’t the only symptom of brainiac cancer .
vexation that get worse over fourth dimension are a common symptom of brain neoplasm . But mentality tumors can cause a number of other symptoms , including blurred visual sense , trouble with symmetry , ictus and personality changes , according to the ACS .
It ’s important to note that these symptom are commonly not do by a learning ability tumor , but if you have these symptoms , you should speak with your doctor so that he or she can determine the cause , the NCI says .
Cellphones are n’t proven to cause brain malignant neoplastic disease .
Most studies have not observe a link betweencellphone use and the risk of brain neoplasm .
Cellphones emit radio - frequency get-up-and-go , which can be immerse by tissue , harmonize to the NCI . But so far , the only eff biological effect of this vigour , which is also emitted by microwave oven oven , is a tiny upgrade in temperature , the NCI enunciate .
Unlike the ionise radiotherapy , radio set - frequency energy is not do it to damage DNA . ( terms to DNA is moot a necessary whole tone to get malignant neoplastic disease , the NCI say . )
In addition , between 1987 and 2007 — a period when cellphone use go up speedily — there was no increase in diagnoses of psyche cancer in the United States , the NCI tell .
