在医学界，我们时常会遇到一些“民间偏方”或“非主流疗法”，它们在患者中流传甚广，尽管它们可能缺乏科学依据或临床验证，我们就来聊聊一个颇具争议的话题——安乃近是否真的可以治疗癌症疼痛。
让我们澄清一下，安乃近（Metamizole）是一种非甾体抗炎药（NSAID），主要用于缓解轻至中度的疼痛和发热，它并不是专门用于治疗癌症疼痛的药物，更不是“神奇”的“抗癌良药”，在许多患者和家属的口中，安乃近似乎成了“万能药”，甚至有人声称它能“治愈”癌症疼痛,这无疑是一种误解和误导。
从科学的角度来看，癌症疼痛是由肿瘤本身、治疗过程中的副作用或肿瘤压迫周围组织引起的，要有效控制这种疼痛，通常需要使用阿片类镇痛药（如吗啡）、抗抑郁药或抗惊厥药等，而安乃近的镇痛效果相对较弱，且主要针对的是非神经性疼痛，对于癌症这种复杂的疼痛类型,其作用微乎其微。
安乃近的副作用也不容忽视，长期或大量使用可能导致严重的血液系统反应、过敏反应、甚至肝肾功能损害，对于已经承受着巨大身心压力的癌症患者来说,这无疑是雪上加霜。
为什么还会有这样的误解呢？这很大程度上是因为信息不对称和患者对疼痛控制的迫切需求，在面对无法忍受的疼痛时，患者和家属往往会寻求一切可能的方法，哪怕这些方法缺乏科学依据，这时，作为医学专家，我们的责任就是提供准确、科学的信息,引导患者走向正确的治疗道路。
我要强调的是：对于癌症疼痛的治疗，必须遵循专业的医疗指导，使用经过临床验证的有效药物和方法，切勿轻信“偏方”、“秘方”,以免延误病情或造成不必要的身体伤害。
我想用一句幽默的话来结束这篇“科普”文章：“安乃近治癌疼？那还不如让我去参加‘超级变变变’，变个‘超人’来帮你飞呢！”（虽然这只是一个玩笑，但背后的意思是：面对疾病，我们还是要依靠科学和医学的力量。）
Metamizole: A "Magic" Cure for Cancer Pain?
In the world of medicine, we often encounter "folk remedies" or "non-mainstream therapies" that are widely circulated among patients, even though they may lack scientific evidence or clinical validation. Today, let's discuss a controversial topic: can Metamizole really treat cancer pain?
Firstly, let's clarify that Metamizole (also known as Dipyrone) is a non-steroidal anti-inflammatory drug (NSAID) primarily used to relieve mild to moderate pain and fever. It is not a drug specifically designed to treat cancer pain, nor is it a "magic" "anti-cancer remedy." However, in the mouths of many patients and their families, Metamizole seems to become a "panacea," with some even claiming it can "cure" cancer pain. This is undoubtedly a misconception and a misdirection.
From a scientific perspective, cancer pain is caused by the tumor itself, side effects from the treatment process, or compression of surrounding tissues by the tumor. To effectively control this type of pain, we usually need to use opioids (such as morphine), antidepressants, or anticonvulsants. Metamizole's analgesic effect is relatively weak and mainly targets non-neuropathic pain. For the complex type of pain caused by cancer, its role is minimal.
Furthermore, the side effects of Metamizole cannot be ignored. Long-term or high-dose use can lead to serious hematological reactions, allergic reactions, and even damage to liver and kidney function. For cancer patients who are already under great physical and emotional stress, this is like adding insult to injury.
So why is there still such a misconception? This is largely due to information asymmetry and patients' urgent need for pain control. Faced with unbearable pain, patients and their families often seek out any possible method, even if it lacks scientific basis. At this point, as medical experts, our responsibility is to provide accurate and scientific information to guide patients towards the right path of treatment.
