Shoulder pain and lung cancer: Exploring the connection
Shoulder pain can be a concerning symptom, especially when it persists or worsens over time. While it's often linked to common conditions like muscle strains or osteoarthritis, shoulder pain can also be a sign of more serious health issues, such as Pancoast tumors and certain types of lung cancer.
Pancoast tumors, a rare form of lung cancer, are known to develop in the upper part of the lungs. They can cause shoulder pain as one of the first symptoms, often due to the tumor invading the brachial plexus or nearby nerves[1][3][5]. In fact, 96% of people with Pancoast tumors report shoulder pain[6].
Another less common, but potentially serious, cause of shoulder pain is mesothelioma, a type of lung cancer associated with exposure to asbestos. While mesothelioma primarily affects the lining of the lungs or abdomen, it can lead to pain in the chest that may radiate to the shoulders. However, this is less common compared to Pancoast tumors[2].
Other conditions that can cause shoulder pain include aortic dissection, gallbladder disease, and various musculoskeletal issues. Aortic dissection, a vascular emergency, can cause severe shoulder pain, typically described as tearing or ripping[1]. Gallbladder disease can cause right shoulder pain due to referred pain from diaphragmatic irritation[1].
It's essential to distinguish the features of these conditions to ensure prompt and accurate diagnosis. For instance, Pancoast tumors often cause severe, worsening pain that may not respond well to typical pain relief measures and can radiate down the arm[5]. On the other hand, mesothelioma, while not commonly associated with shoulder pain directly, may present with chest pain that indirectly causes discomfort in the shoulder area.
Given the potential seriousness of these conditions, it's crucial to seek medical attention if shoulder pain persists or worsens. If you experience shoulder pain that lasts more than a few days, goes away and then returns, or becomes unbearable, it's important to visit a doctor to rule out serious underlying conditions.
For those diagnosed with lung cancer, treatment can help improve their quality of life. However, recognizing symptoms early on is critical for improving the life expectancy of a person with lung cancer. Lung cancer is one of the most dangerous forms of cancer because it can spread rapidly. Among those in whom a doctor detects and treats lung cancer before it spreads, about 56% will live for 5 years beyond diagnosis. However, once lung cancer reaches distant sites in the body, the 5-year survival rate reduces to 5%[7].
In conclusion, shoulder pain can be a symptom of several serious conditions, including Pancoast tumors and other diseases that may mimic the symptoms of mesothelioma. If you're experiencing persistent or intense shoulder pain, it's essential to consult a healthcare professional for advice and guidance.

- The shoulder pain persisting or worsening could be a sign of Pancoast tumors, a rare form of lung cancer that develops in the upper part of the lungs and is known to cause shoulder pain.
- Nonsmall cell lung cancer, like Pancoast tumors, can also cause shoulder pain, as well as chest pain, and is associated with more serious health issues.
- However, mesothelioma, another type of lung cancer associated with exposure to asbestos, can cause chest pain that may indirectly lead to discomfort in the shoulder area.
- Other health-and-wellness conditions, such as aortic dissection, gallbladder disease, or musculoskeletal issues, can also cause shoulder pain.
- Science and medical-conditions advancements have shown that early detection and prompt treatment of lung cancer greatly improve the patient's life expectancy and quality of life.
