RELATED: If You Feel This in Your Throat, Get Checked for Cancer. Most of the tell-tale symptoms of lung cancer are respiratory in nature. For exactly this reason, patients often disregard one little-known symptom that doesn’t fit the standard profile: a persistently hoarse voice. “Hoarseness is a less-known symptom of lung cancer,” explains the Roy Castle Lung Cancer Foundation. “If you are experiencing longer episodes of hoarseness, you should contact your GP practice,” the organization’s experts write. A hoarse voice resulting from lung cancer may present in a variety of different ways, so it’s important to look out for anything that deviates from your own sense of normalcy. You may notice that your voice sounds “raspy, husky, strained, breathy, weak, inconsistent” or “tired,” the foundation says. RELATED: If You Notice This on Your Face, Get Checked for Cancer. Several conditions other than lung cancer can cause a hoarse voice. Examples include laryngitis, swelling of the voice box, acid reflux, and a build up of soft tissue on the vocal cords from smoking, says the Roy Castle Lung Cancer Foundation. Environmental factors such as humidity and air pollution can also increase your likelihood of developing a hoarse voice. In some cases, laryngeal cancer—which directly affects the cells lining the voice box—can also cause hoarseness. Experts say that if your hoarse voice is caused by “irritation or injury to the vocal cords,” the problem should resolve on its own within a relatively short period of time. It’s easy to imagine how cancer of the larynx could cause a hoarse voice, but the connection between lung cancer and hoarseness is perhaps less obvious. According to Health Union, lung cancer patients may experience hoarseness as resulting from paralysis or weakness in the laryngeal nerve. When this occurs, it is known as laryngeal nerve palsy. “The recurrent laryngeal nerve controls the action of the larynx and is split into a left and right nerve,” their experts explain. “The recurrent laryngeal nerve has an indirect route through the body, with the left passing through the chest cavity close to the left lung. Tumors in the left lung can press on the nerve, causing hoarseness, or recurrent laryngeal nerve palsy. Although less common, right lung tumors can also cause recurrent laryngeal nerve palsy.” For more health news sent directly to your inbox, sign up for our daily newsletter. If you notice hoarseness in your voice that does not resolve on its own, it’s important to speak with your doctor about your concerns. Additionally, it’s useful to be aware of the other symptoms of lung cancer, which may help to know if there’s a deeper problem.ae0fcc31ae342fd3a1346ebb1f342fcb According to the Centers for Disease Control and Prevention (CDC), these symptoms can include a persistent cough that becomes worse over time, a cough that produces blood or rust-colored phlegm, chest pain, shortness of breath, wheezing, fatigue, and weight loss with no known cause. “Other changes that can sometimes occur with lung cancer may include repeated bouts of pneumonia and swollen or enlarged lymph nodes (glands) inside the chest in the area between the lungs,” the CDC writes.
