Brain cancer refers to the abnormal growth of cells within the brain, which can be malignant (cancerous) or benign. Malignant brain tumors are aggressive and can invade nearby tissues, causing serious health problems. Common symptoms of brain cancer include headaches, seizures, nausea, speech difficulties, and cognitive impairments. Research in brain cancer focuses on understanding the causes of these tumors, developing better diagnostic tools, and exploring more effective treatment options. This includes studying the genetic and molecular factors that contribute to brain cancer development, as well as investigating new therapies such as targeted drug treatments, immunotherapy, and surgical techniques. Overall, research in brain cancer aims to improve early detection, enhance treatment outcomes, and ultimately find a cure for this devastating disease.
