Description

When abnormal cells grow within the brain, a brain tumor develops. Cancerous (malignant) tumors and benign (noncancerous) tumors are the two basic forms of tumors. Primary tumors, which begin within the brain, and secondary tumors, which most usually spread from cancers outside the brain and are known as brain metastasis tumors, can be further categorized. Symptoms of all forms of brain tumors vary depending on the size of the tumor and which section of the brain is affected. Headaches, seizures, eyesight difficulties, vomiting, and mental abnormalities are some of the symptoms that might occur. Other signs and symptoms include trouble walking, speaking, feeling numb, or being unconscious.

The majority of brain tumors have really not recognized aetiology. Vinyl chloride exposure, Epstein–Barr virus infection, ionizing radiation, and hereditary diseases including neurofibromatosis, tuberous sclerosis, and von Hippel–Lindau disease are all uncommon risk factors. There has been no conclusive evidence of a danger from cell phone use in studies. Meningiomas (typically benign) and astrocytomas, such as glioblastomas, are the most prevalent forms of primary tumors in adults. Malignant medulloblastoma is the most prevalent form in youngsters. Medical examination and computed tomography (CT) or magnetic resonance imaging (MRI) are commonly used to make a diagnosis (MRI). A biopsy is frequently used to confirm the outcome. The tumors are graded according to their severity based on the results.

Signs and Symptoms

Brain tumors include a wide range of indications and symptoms. Symptoms can occur whether the tumor is benign (noncancerous) or malignant (cancerous). Symptoms of primary and secondary brain tumors are similar, depending on the tumor’s location, size, and pace of growth. Larger tumors in the frontal lobe, for example, might affect one's capacity to reason. A smaller tumor in a region like Wernicke's area (a tiny area involved for language comprehension) might cause more function loss.

Headaches

Increased intracranial pressure can cause headaches, which can be an early sign of brain cancer. However, isolated headaches with no other symptoms are uncommon, and other symptoms, such as visual abnormalities, may appear before headaches become widespread. Certain headache warning indicators exist, making the headache more likely to be linked to brain cancer. The American Academy of Neurology defines these as: abnormal neurological examination, headache worsened by Valsalva manoeuvre, headache waking you up from sleep, new headache in the elderly, progressively worsening headache, atypical headache features, or patients who do not meet the strict definition of migraine. Headaches that are worse in the morning or go away after vomiting are other indicators.

Location-specific symptoms

The brain is split into lobes, each of which serves a distinct purpose. A tumor in any of these lobes might impair the functionality of the region. The symptoms are frequently tied to the tumor’s location; however each person may have a unique experience. Frontal lobe Tumors can cause problems with cognition, incorrect social conduct, personality changes, poor planning, inadequate inhibition, and speech output (Boca’s region). Temporal lobe tumors in this lobe can cause memory loss, hearing loss, and difficulties understanding language. Parietal lobe tumors in this area can cause problems with language interpretation, speaking, writing, drawing, naming, and recognizing, as well as impaired spatial and visual perception. Occipital lobe damage to this lobe might cause blurry vision or even blindness. Cerebellum tumors in this region can lead to problems with balance, muscular mobility, and posture. Brain stem seizures, endocrine issues, respiratory abnormalities, visual alterations, headaches, and partial paralysis are all symptoms of brainstem tumors.

Behaviour Changes

Because the tumor has damaged the lobes of the brain, a person's personality may be affected. Because the frontal, temporal, and parietal lobes are responsible for inhibition,emotions, mood, judgment, reasoning, and behavior, a tumor in those areas can result in inappropriate social behavior, temper tantrums, laughing at inappropriate times, and even psychological symptoms like depression and anxiety. More research into the efficacy and safety of antidepressant medication in people with brain tumors is needed. Changes in personality can have negative consequences such as unemployment, shaky relationships, and a loss of control.

Conclusion

Surgery, radiation therapy, and chemotherapy are all options for treatment. Anticonvulsant medicine may be required if seizures occur. The drugs dexamethasone and furosemide may be used to reduce edoema around the tumor. Some cancers develop slowly, requiring just observation and probably no additional treatment. Treatments that rely on a person's immune system are currently being investigated. Malignant tumor outcomes vary greatly depending on the type of tumor and how far it has gone at the time of diagnosis. Although benign tumors only develop in one place, their size and location might make them lifethreatening. Glioblastomas that are malignant have a bad prognosis, but benign meningiomas have a fair prognosis. In the United States, the average five-year survival rate for all (malignant) brain malignancies is 33%.

Secondary brain tumors, also known as metastatic brain tumors, are nearly four times as prevalent as primary brain tumors, with lung cancer accounting for about half of all metastases. Primary brain tumors affect about 250,000 individuals worldwide each year, accounting for less than 2% of all malignancies. Brain tumors are the second most prevalent type of cancer in children under the age of 15. Acute lymphoblastic leukemia is the most common cancer in children under the age of 15.
