Brain Lesion Vs Brain Tumor
"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
: There can be benign tumors in the brain like meningioma or acoustic neuroma. These tumors are not malignant, but can cause symptoms and complications, and are often treated with surgery or radiosurgery. There can be malignant tumors in the brain (cancer). These can be metastatic, or be of primary brain origin. ...Read moreSee 1 more doctor answer
Not quite: A pituitary tumor arises from the pituitary gland which is underneath the brain. These may be quite large and cause compression of the brain or the cranial nerves. This would be considered a "brain tumor" in general language. Pituitary tumors should be classified in a category of their own from a technical standpoint. ...Read moreSee 1 more doctor answer
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
Pathology type: Brain tumor is a generic term that includes benign, low grade and malignant brain tumors. Brain cancer refers to the malignant category. When one speaks of a brain cancer, this may be a primary (originating from the brain tissue) or metastatic (originating from cancer outside of the brain). Treatment depends on the type of cancer. ...Read more
Hard to say: If the interpretation on the MRI by the radiologist is that it is a cyst, then it is likely benign. It also depends if there is any area of enhancement that would suggest a tumor. Also if you have serial MRI scans, you can tell if it is getting bigger or changing which is more likely a tumor. The location in the ventricle is important too. If it obstructs the foramen it could be a problem. ...Read moreSee 1 more doctor answer
In theory anywhere: In theory, it could happen anywhere in the brain, but most juvenile pilocytic astrocytomas are in the supratentorial brain (outside of the posterior fossa). Posterior fossa tumors are typically ependymoma, medulloblastoma in kids. Jpa's don't happen in adults (adults get lgg's, or who ii low grade gliomas..Just almost never who i tumors). Most stem lesions are not jpa's, but they happen too. ...Read moreSee 1 more doctor answer
Not typically: The pineal gland is located in the center of the brain near eye nerve pathways and the cerebrospinal fluid (CSF) system. Symptoms include double vision, headache, nausea, & vomiting. I suspect seizures could happen but are not common. Pineal tumors are also rare .. only 1% of all primary brain tumors. Other causes of seizures should be investigated. ...Read moreSee 1 more doctor answer
Merely technical: Looking directly at base of brain and pituitary requires slightly different cuts and angles, as the focus is directed to a small area of brain, but the software and pictures are handled in a similar fashion. In ms, we tend to use specialized approaches, such as flair or double inversion recovery to see the white matter spots better. Not needed for pituitary views, usually. ...Read more
Neurosurgeon: Most neurosurgeons can do this surgery. Depending on the size of the pineal tumor, you may want to call around to different universities or large medical centers and ask if there is a neurosurgeon who does endoscopic surgery and may do your tumor. But any neurosurgeon can give you the proper consultation. ...Read more
Took brain mri.multiple t2hypointense lesion in cerebral parenchyma.possibilty of granuloma or brain secondries..my mom hv lung cancer.is it secondary?
Probably neither: Difficult to know without seeing all the MRI sequences. It would be helpful to know if the lesions enhance after Gadolinium contrast and if they "bloom" on susceptibility weighted sequences and if they are calcified or invisible on CT scan. Metastatic disease would be very unlikely in a 30 year old without a known primary cancer. My best guess would be multiple cavernous malformations. ...Read more
Get best care: The optimal care for a high grade glioma will often be found at a major academic medical center. Treatment is first surgery, to remove the maximum amount of tumor possible, followed by radiation and chemotherapy, often together. All of this also requires good neuroradiology, good neuropathology, good nursing care and supportive care of all types. Don't be shy about asking for second opinions. ...Read more
Very little chance: Because our understanding of radiation induced cancer is incomplete, it is assumed that any exposure to radiation increases the risk of developing cancer. This is called the non-threshold model. According to a recent nejm article the risk is approximately 0.005% at age 35 that a single ct brain would cause death due to cancer. N engl j med 2007; 357:2277-2284. The risk is even smaller at > age. ...Read more
MRI showed brain lesion... What will they do next? And can it be something seriouse. If it was a brain tumor would they have known from this MRI
It depends: The MRI is very good, but not perfect in identifying what the lesion is. The treatment will depend on what the MRI shows. If it is not clear, either it will be followed with serial MRIs or it will be biopsied. If it is known, it will be either followed or treated depending on what it is. Occasionally, it will be surgically removed. ...Read moreSee 2 more doctor answers
Brain lesion. i was told it was a brain tumor, acute disseminated encephalomyelitis, and cortical dysplasia could it still be a brain tumor? thanks!
Huh?: Didn't you just answer your own question? Maybe I'm missing something but if the diagnosis actually IS ADEM (as I believe you are saying above) and if what you have is cortical dysplasia (unrelated to the ADEM) to boot then, neither of those 2 together nor separately are synonyms for brain tumor. Do you have imaging studies? That would solve the mystery? Questions? www.healthtap.com/drsaghafi ...Read more

If I've had bladder issues for over 2 1/2 yrs and am now having a bladder tumor, what are the chances of metasizing cuz I have a brain lesion also?
A little confusing: So, you didn't say WHAT the brain lesion was...if it's a mass such as tumor...and IF that mass has the same structural characteristics as the tumor in the bladder then, that's an example of a metastatic lesion. If the brain lesion is not a tumor and something unrelated then, the chance of metastasizing the bladder tumor really depends on its type as to how aggressive it might be. All the best. ...Read more
Why do neurosurgeon say no to fix two small angionomas with lesion and they won't do MRI to see if it is a brain tumor starting live in Utah .
Angiomas: Not every angioma needs an MRI or MRA to be evaluated. If there is a clear angioma on CT scan, and it is small, an MRI would probably not help. And in such a case, surgery could do more harm than good. If the diagnosis is not certain, than an MRI or MRA can help determine what it is. Do you mean a cavernous hemangioma? It should be removed only if it is deemed to be a risk. ...Read more
August MRI with contrast showed brain lesion they say was very small and nothing to be concerned about. Could it have turned into a malignant tumor ?
Can't say: Can't say without seeing your MRI, but if you are not having symptoms and the lesion appears benign, then I would not worry if your doctor is not worried. A good question to ask your doctor is, "What would you do if you were in my situation and this was your MRI?" If the answer is nothing, then I would be pretty reassured. You could also ask if a repeat MRI would be wise to check for changes. ...Read moreSee 2 more doctor answers
If i suspect a brain lesion, tumor or damage, is asking my dr for a scan reasonable? Mri or CT better?
I had my tumor removed with lobectomy, no lymph nodes but small brain lesion treated with stereotactic radiation. Should II get chemo?
Depends: It depends on the type of tumor because they are not all created equally. If the tumor is removed with surgery and responded well to radiation, and your doctor recommends chemotherapy because that is known to work for the type of tumor you were diagnosed with, then it would be worthwhile. ...Read more
Can cancer or a brain tumor cause some sort of rapidly growing white/yellow mass/lesion in retina (spot in central vision)?
Dad,Oscar,was told stage 4 lung cancer 2.5 wks ago. 1/3 sz brain tumor removed. 3 brain lesions. In bones&pos liver. Would u cyperknife brain tomorrow?
It depends: If you are 76, your Dad must be late 80s or early 90s. At such an advanced age it may not be worth being so aggressive with terminal cancer that at such advanced stage means he has only few weeks to few months left. However, if his desire is to be aggressive, Cyberknife is an effective an low risk procedure and I would recommend it highly. Otherwise, hospice care is very appropriate. ...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
Headache,nausea,visi: Symptoms of brain tumor depend on location and size of the tumor.Hradache more frequent and severe, nausea&vomiting, visual problems, seizures, weakness or loss of function in arm or leg, speech difficulty, hearing problem, confusion, personality and behaviour changes. ...Read more
There are none: Brain tumors rarely develop extra neural metastases. They are graded based on pathology. Gx cannot be graded, g1 well differentiated, g2 moderately differentiated, g3 poorly differentiated, g4 undifferentiated. The reason why there is rarely metastasis is because the brain does not have a well-developed lymphatic drainage system. Hope this helps. ...Read moreSee 1 more doctor answer
