9 Sneaky Lung Cancer Symptoms

肺癌的最常见的症状就是“以人实际上没有任何症状！”解释弥敦道彭内尔，医学博士，博士，在克利夫兰诊所的陶西格癌症中心在俄亥俄州的一个肿瘤科医生。鉴于此，他说你最好的选择是保持警觉，“什么，只是没有当它应该走了。”如果有以下症状萦绕超过一个月，或者更长，从而没有明显的说明，警示医生，他说。在大多数情况下它won’t是癌症。“这将是正常的东西！”他说。但是意识支付：早期发现，当肺癌有时是可以治愈的。下面是应该注意什么。

This symptom is what most people relate to lung cancer, says Dr. Shu. "If you have a chronic cough, such as smoker's cough, and certainly, if you cough up blood or phlegm that’s in any way reddish or pink, see your doctor,” she says.

Most of the time a cough is happening for understandable reasons, such as a cold, says Dr. Pennell. It’s when it doesn’t ease up that you should snap to attention. “The average time a cough lasts after a virus is three weeks,” he explains. Hacking away for much longer than that? You know what to do.

If your airways are narrowed for some reason, you may hear a whistling or whining sound when you exhale, says Dr. Pennell. The symptom can be caused by problems such as asthma, emphysema, as well as lung cancer (the wheezing may result from air pushing past a tumor that's pressing on the airway). “This sound concerns people, because you usually don’t hear yourself when you breathe,” he says. On the other hand, a lot of long-time smokers are so used to wheezing that it stops setting off alarm bells. Remember: Wheezing isn’t normal, so get it checked out.

It can be disconcerting to find yourself huffing and puffing when you're used to whizzing around without a second thought. “Shortness of breath can indicate a number of different things, from emphysema to pneumonia or even a blood clot,” explains Dr. Shu. When the culprit is lung cancer, the shortness of breath can come on in a stealthy way that you hardly notice...until one day you do.

"Everyone sort of knows how much exercise they can do before they have to stop and catch their breath,” says Dr. Pennell. So if the climb from the basement to the upstairs bedroom was easy in January but is now daunting in February, give the doctor a ring.

减肥是一个经典的癌症相关的标志，虽然不是一个必要特定肺癌彭内尔博士说。癌症可以使你减肥随着病情的烧伤了身体的能量供给并改变你的食物处理能源的方式。“最严重的疾病可能导致此，以及能量的损失。”而且，由于几乎没有人减肥，但不尝试，他补充说，这是一个好主意，告诉你的医生，如果你落下磅，没有任何明显的努力。

你可以实实在在地感受到这种偷偷摸摸的肺癌症状罚款，没有注意到什么奇怪比你的声音小青蛙等。但是，当这种情况发生时，它可以是一个迹象，表明癌症已经以某种方式被压缩的神经支配是声带连接到肺部。“谁都有声音嘶哑或咽喉炎的人通常有它一两天，然后就消失了，”他说。“但是，如果你不经过几天或一个星期来恢复正常，这是更加令人担忧。”

彭内尔博士说，当肺部感染如肺炎回头客或永远不要真的走了，肺癌的值得投入的条件名单上得到检查。肺炎是由感染引起的与细菌或病毒的肺部炎症。癌症链接是一个原因医生询问诊断的人返回后随访胸部X光检查肺炎，确保肺炎走了，一个肿瘤，这是非常小的，是不是潜伏在肺部。很多肺癌患者被误诊为个月以上，因为这种疾病可以表现为肺炎，甚至感冒或过敏，根据美国肺脏协会。

Lungs have no nerve endings, so you can’t actually feel pain from a tumor there, explains Dr. Shu. “But a tumor could invade your chest wall or extend into the pleura (the lining of the lungs), both of which are sensitive to pain.” Some people develop a dull or aching discomfort around the rib cage, shoulder, lower back, or along the outside of the arm; white blood cells can pool in large numbers and damaging the bones. But unlike pain from an injury, lung-cancer pain doesn't go away. Instead, it tends to get worse over time, stresses Dr. Pennell.

Since there can be so many serious reasons for having chest pain, including heart issues, it’s important to always get this problem checked out right away, says Dr. Pennell. It’s not common, but lung cancer can be a cause. The American Cancer Society describes lung cancer-related chest pain as “often worse with deep breathing, coughing, or laughing.” It may feel like a dull, persistent ache.

不幸的是，从癌症感觉胸部不适“通常一个标志，它已经成为相当先进，”彭内尔博士解释说，并已侵入周围你的胸部胸膜或骨骼。

This relatively rare but dramatic sign of lung cancer shows up in 15% of people diagnosed with lung cancer,according to the research in the journal龙印.

下面是它可以是什么样子：钉子取一汤匙的背面的形状，它们可能看起来几乎漂浮在甲床的上方。手指可能会红，肿，发炎，并期待像小香肠。没有人知道到底是什么原因导致杵状指。它可能在营养丰富的氧气通过体内循环下降的提示，或者它可能是癌症激活某些物质在血液中，引起甲床增厚。不管是什么原因，如果这些变化发生在你身上，让这一任命。
