Astroglioma Brain Tumor
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.
"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
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.
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.
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.
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.See 2 more doctor answers
PROCESS: First is doctors suspicion or if symptoms (headaches, seizures, nausea, vomiting), then focused physical exam followed by appropriate imaging studies (ct or MRI of brain), if a lesion is seen then it will require tissue diagnosis. Can be obtained by biopsy or surgical removal of suspicious lesion. The final word is the pathology results.
Yes: It can cause transient worsening depending on the pressure of the brain, which is usually higher early morning. It can also present with seizure, which might not be a typical convustion attack, but mimicking mini-stroke. Please seek medical attention, if you have any concerns.See 1 more doctor answer
No: Brain tumors are relatively uncommon, and the peak age for the most common type of brain tumors is between the fifth and seventh decades of life (40-70). Such tumors are uncommon in people in their 20s, but it can happen. If your question is from more than just curiosity, see your doctor for more information and perhaps for a brain MRI scan.See 1 more doctor answer
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.See 1 more doctor answer
Complex issue: Tumors of the brain can be benign, malignant, malignant by position, or chronic and stable. Brain tumors can be silent or present as seizures or can abruptly produce coma and death. Primary brain tumors depend on cells of origin and location as to how they show symptoms. Secondary brain tumors may come from a primary tumor elsewhere in the body and spread broadly all through the brain.
