Brain Cancer
Brain cancer begins when abnormal cells form within the brain tissue and grow uncontrollably, forming a tumor. These tumors can be primary (originating in the brain) or secondary/metastatic (spreading from cancers elsewhere in the body). Some tumors are benign, but malignant tumors can be life-threatening due to their impact on brain functions.
Understanding the Causes & Protection
Risk Factors & Prevention
– Exposure to high-dose radiation (especially to the head)
– Family history of brain tumors
– Certain genetic disorders (like Li-Fraumeni or Turcot syndrome)
– Age (some types are more common in children, others in older adults)
– Prolonged exposure to chemical or industrial toxins
– No proven lifestyle prevention, but general health maintenance helps
How can it be prevented?
– Avoid unnecessary radiation exposure to the head
– Use protective gear if working in chemical industries
– Manage overall health and limit exposure to environmental toxins
– Early detection if genetically predisposed (genetic counseling)
Screening
– No standard screening for brain tumors in the general population
– Neurological exams, imaging (MRI, CT scans) done when symptoms appear
– Regular monitoring for high-risk individuals (genetic conditions or past cancers)
Symptoms
– Persistent or worsening headaches (especially in the morning)
– Seizures or convulsions
– Memory problems or personality changes
– Nausea or vomiting (often in the morning)
– Vision or hearing issues
– Weakness or numbness in limbs
– Difficulty with balance, coordination, or speech
– Cognitive decline or confusion
