How Do U Know If U Have A Brain Tumor
Can u have a brain tumor for 7 years and only have lightheaded feeling sometimes funny vision etc dr says anxiety I pass neuro exam but really worried?
Brain cancer refers to cancer located in the brain. It can occur from a metastasis from a tumor in another part of the body or can originate in the brain. Symptoms of brain cancer include headaches, weakness, dizziness, seizures, and blurry vision. It can sometimes be asymptomatic as, for example, in patients with small cell lung cancer. It is always best to use MRI with contrast to make an evaluation, since using a CT can cause you to miss ...Read more
How common is a brain tumor in the u.S. Compared to the same age group in a non-industrialized place?
Maybe higher: It's hard to know for sure, because industrialized countries have better registries and are more likely to keep track of brain tumors. There may be a slightly higher rate of brain tumors in the us compared to a non-industrialized country, but the difference is small. Brain cancers are rare, with about 230, 000 diagnoses worldwide each year. Chemicals, hiv, and radiation are some of the causes. ...Read more
Abnormal cell growth: All tumors are formed from cells that do not follow the rules - they grow faster/differently than they should, not controlled by local and systemic chemical signals. There are many different types of brain tumors - some very slow growing over decades that cause no problems but may "push" the brain a little. But others grow very fast, damaging or "crushing" normal brain next to them. ...Read more
Tumor origins: Brain tumors, like any neoplasms in the body, can be induced by an interplay of genetic and environmental factors. In other words, there are inherited predispositions in some cases. One environmental factors known to induce some brain tumors is radiation exposure. Unfortunately, there is much that we still do not know about how these tumors start. ...Read more
Most are random: All tumors result from accumulated genetic mutations that give a growth advantage to clones of cells. Most strike at random without clear environmental risks. A few familial syndrome (turcot's, neurofibromatosis, von hippel-lindau, lifraumeni, some rarities) feature increased risk for one or more types of brain tumors. If you have a brain tumor, nothing that you did caused it. Wishing you the best. ...Read more
Dumb luck: A few genetic syndromes put people at increased risk for brain tumors. Beyond this, we almost never find a cause. Tumors result from random mutations that become propagated. No one's to blame. Scientists who build careers by demonstrating new truths have failed to identify anything credible. The cell-phones claim has no rational or empirical basis. Best wishes. ...Read more
Depends on location: Some brain tumors are located in the frontal area and are almost clinically silent until size increases. Some early on may cause focal weakness, which looks like a stroke. Headaches, nausea, vomiting, visual blurring, and double vision can occur as size increases. Many tumors, though, may be picked up on routine MRI films. Some tumors start in lung or kidney and metastasize to brain. ...Read moreSee 2 more doctor answers
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
