Zhongu Grandpa, a man in his sixties, recently experienced frequent headaches. Accompanied by his family, he visited the local hospital for a check-up. After a comprehensive examination, including observation of the head, neck, and lymph nodes for abnormal masses, as well as tests for neurological indicators, the doctor found no abnormalities.
However, blood tests showed slightly elevated inflammation markers, and radiology exams revealed a blurry mass in the upper right lung. A biopsy confirmed the presence of malignant tumor cells, indicating lung cancer. The doctor explained that headaches, along with other unusual symptoms in the head, could be signals of lung cancer.
