Malignant Brain Tumor Symptoms
Had a fear of brain tumor for 7 months. Ct scan without contrast was clean. Would I be having severe symptoms by now if it was malignant?
Brain tumors aren't easily categorized into benign or malignant: Although the most aggressive type of brain tumor, glioblastoma, would likely be causing severe symptoms by now, there are other types of brain tumors that can be serious but not grow as quickly. The majority, however, would be associated with progressive symptoms during this time period. An MRI is the best test to evaluate potential masses in the brain. ...Read more
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
Actually`: Some believe that it takes only the time for a SINGLE CELL which has MUTATED (or produced by an abnormal strand of RNA/DNA to START tumor formation. As to how long it takes for SYMPTOMS to occur THAT depends upon the LOCATION of the TUMOR and whether it IRRITATES surrounding tissue ("produces" a siezure) Hope this helps! Dr Z ...Read more
Sometimes: It depends on the type of tumor. Many cases of the most common type of brain malignancy in children, medulloblastoma, can probably be cured with surgery, radiation, and chemotherapy. Most high grade gliomas are not curable, but are treatable to give some useful extended survival. Talk this over with your doctors and seek information about the children's oncology group's protocols. ...Read more
Typically not: The size of a tumor usually doesn't determine whether the tumor is benign or malignant. I've had patients with very large tumors that are benign and tiny tumors that are malignant. Whether or not a tumor is benign or malignant depends on what type of cells the tumor is composed of. Often the only way to determine this is with biopsy. ...Read more
Radiosurgery, either: Linac or gamma knife, is not commonly used for glioma, but is regularly used for metastatic lesions. The procedure usually takes a day, including frame fixing, mr to identify lesion(s), and tehn treatment delivery. But you walk out of the suite and go home. May feel some fatigue, head ache, nausea. No aftermath is common. ...Read more
Can i fly with a 3.1cm brain tumor i haven't found out if its malignant. My flight is 2 hrs 30 minutes may 6-12.
Depends: A lot depends on the location of the tumor… is this tumor within the brain itself? Is it on the periphery of the brain causing pressure on the brain? One risk of having a brain tumor would be to develop seizures and you should be on prophylactic anti-seizure medication. I would inquire with your doctor if he believes that this is a slow growing tumor then it could possibly be safe to fly… you would still need to accept the risks involved such as having a seizure while on the airplane. ...Read moreSee 1 more doctor answer
The only difference in classifying a benign vs. Malignant brain tumor is the speed of it's growth. Is this really true?
Brain Tumor, B or M?: Definitive classification of a benign vs. Malignant brain tumor can only be made with absolute certainty based on the histologic features of the brain tumor. Speed of tumor growth may be suggestive but not reliable. A very low-grade malignant brain tumor may grow very slowly like the benign ones. Keep in mind, a biologically benign brain tumor can still cause serious damage given its location. ...Read more
Hard question: Any brain tumor can be malignant by position. Even if benign but in vital region is bad. A malignant metastasis may be easy to remove and cured by cure of the source. A primary malignant brain tumor may be easy to remove and cure or can be diffuse and impossible to remove or cure. ...Read moreSee 1 more doctor answer
The term malignant can be used in several medical contexts, but is primarily used to describe cancers. More dangerous and disorderly than the benign growth of cells, malignant cells have developed genetic changes that can allow it to invade other tissues in an unregulated way. These tumors can later spread, or metastasize, to other parts of the body and ...Read more
"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
