Brain cancer may not hurt at first. An oncologist described the symptoms that may come first

Brain tumors are among the most feared diagnoses, with around 1,000 new cases diagnosed annually in the Czech Republic. While the causes remain largely unclear, common myths, such as mobile phone usage increasing risk, have been debunked. Symptoms can include headaches, vision problems, and changes in behavior. Modern treatments like Optune and CyberKnife offer hope, particularly for aggressive tumors like glioblastoma, although they require discipline and are not suitable for all patients. Success is measured not just by survival but also by maintaining quality of life.
