Which tumors are the most dangerous?
There is no definitive list of "the most dangerous cancers," but clinically, some particularly aggressive tumors include pancreatic cancer, liver cancer, glioblastoma, small cell lung cancer, and cholangiocarcinoma. If unexplained weight loss, persistent pain, or other unusual symptoms occur, prompt medical evaluation is recommended.
1. Pancreatic Cancer: Due to its hidden location and nonspecific early symptoms, it is often diagnosed at an advanced stage. It shows low sensitivity to chemotherapy and radiotherapy, and surgical removal is challenging. Patients typically have a short survival period, earning it the nickname "the king of cancers."
2. Liver Cancer: Early symptoms are subtle, and the liver has strong compensatory capacity. By the time symptoms such as abdominal pain and jaundice appear, the disease is often already in the late stages. It frequently spreads within the liver and forms tumor thrombi in the portal vein, leading to high recurrence rates after treatment.

3. Glioblastoma: This is the most malignant type of intracranial tumor, characterized by rapid growth and invasion into surrounding brain tissue. Complete surgical resection is difficult, and recurrence after surgery is common. The average survival time for patients is short.
4. Small Cell Lung Cancer: A type of neuroendocrine tumor with rapid proliferation, it tends to metastasize early. Although initially responsive to chemotherapy and radiotherapy, resistance quickly develops, resulting in rapid disease progression and poor prognosis.
5. Cholangiocarcinoma: Lacking specific early symptoms, it often invades surrounding tissues or has already metastasized by diagnosis. Surgical resection rates are low, and responses to chemotherapy and radiotherapy are limited. Postoperative recurrence risk is high, and patient survival times are generally short.
These cancers commonly share features such as difficulty in early detection, rapid progression, challenges in treatment, and poor outcomes, so awareness of related warning signs is crucial. In daily life, maintaining regular作息 (lifestyle routines), avoiding unhealthy habits like smoking and excessive alcohol consumption, undergoing regular health check-ups, engaging in moderate physical activity, and boosting overall immunity can help reduce the risk of developing cancer.
