Overview

Brain Tumor
A brain tumor is an abnormal growth of cells in or around the brain. Brain tumors may be benign or malignant and can affect brain function depending on their type, size, location, and rate of growth. Symptoms vary and may include headaches, seizures, changes in vision, weakness, difficulty with speech or movement, personality changes, or problems with memory and thinking.
Influenza
Influenza is a contagious respiratory illness caused by influenza viruses. It commonly develops suddenly and may cause fever, chills, cough, sore throat, muscle aches, headache, and marked fatigue. Some people, particularly young children, may also experience vomiting or diarrhea. Most healthy people recover without serious complications, but influenza can lead to pneumonia and other severe problems in older adults, young children, pregnant people, and individuals with certain chronic conditions or weakened immunity. Seasonal vaccination and appropriate infection-control measures help reduce illness and transmission.

Diagnosis

Brain Tumor
Diagnosis begins with a medical history and neurological examination to assess symptoms and brain function. Imaging studies such as magnetic resonance imaging (MRI) or computed tomography (CT) can identify a mass and show its location and characteristics. When appropriate, a biopsy may be performed to examine tumor cells and determine the tumor type and grade. Additional laboratory or molecular tests may help guide treatment.
Influenza
Influenza can often be diagnosed clinically from symptoms and the pattern of illness during periods of active community transmission. Rapid influenza diagnostic tests may provide results quickly, although their ability to detect infection varies. Molecular tests, including rapid molecular assays and other laboratory methods, can provide more sensitive confirmation when testing is indicated. Testing is particularly useful when the result may affect treatment, infection-control decisions, or evaluation of people at higher risk of complications. The diagnosis should also consider other respiratory infections with similar symptoms.

Prevention

Brain Tumor
There is no reliable way to prevent most brain tumors because their causes are often unknown. Avoiding unnecessary exposure to high-dose ionizing radiation and following appropriate medical guidance when radiation imaging or treatment is required may reduce avoidable exposure. People with known inherited conditions associated with brain tumors may benefit from appropriate medical monitoring and genetic counseling.
Influenza
Annual influenza vaccination is an important measure for reducing the risk of influenza and its complications. Good hand hygiene, covering coughs and sneezes, improving indoor ventilation, and avoiding close contact with people who are ill can reduce transmission. People with influenza should stay home when sick when possible and follow local guidance about returning to normal activities. Higher-risk individuals should seek medical advice promptly when significant influenza symptoms develop because antiviral treatment may be most useful when started early.

Risk Factors

Brain Tumor
Risk factors include exposure to high doses of ionizing radiation, certain inherited genetic syndromes, and a family history of particular brain tumors or related genetic conditions. Some tumors are more common with increasing age, while others occur more often in children or younger adults. Having a risk factor does not mean that a person will develop a brain tumor.
Influenza
The risk of influenza is increased during periods when influenza viruses are circulating widely. Older adults, young children, pregnant people, and individuals with chronic heart, lung, kidney, metabolic, or neurological conditions may have a greater risk of serious complications. Weakened immunity can also increase risk. Close contact with infected people, crowded indoor environments, and inadequate ventilation can facilitate transmission. Lack of seasonal vaccination may increase susceptibility to circulating strains.
