Lung Cancer: An Unexpected Symptom

Lung Cancer: An Unexpected Symptom

Lung cancer is a serious and often life-threatening disease that affects millions of people worldwide.

While most people are familiar with the common symptoms of lung cancer, such as persistent coughing, chest pain, and shortness of breath, there are some unexpected signs that can appear on your hands.

Recognizing these unusual symptoms is crucial for early detection and treatment. In this article, we will explore these lesser-known signs of lung cancer, shed light on the most common symptoms, discuss who is at risk, and emphasize the importance of seeking medical attention promptly.


Among the more obvious symptoms, one unusual sign that should raise concern is the appearance of swollen fingers.

Pay attention if the ends of your fingers appear enlarged, the skin next to the fingernail becomes shiny, or your nails start to curve downwards.

These changes may seem unrelated to lung cancer, but research has shown that approximately 80 percent of people who experience these hand symptoms also have lung cancer.

Therefore, it’s crucial not to overlook these signs and seek medical advice promptly if you notice them.


In addition to hand-related symptoms, lung cancer can also manifest in other unexpected ways. While these symptoms are less common, they should not be ignored. Some individuals with lung cancer may experience eye problems, such as blurry vision or double vision.

Balance issues, dizziness, and unsteadiness on their feet can also occur.

Furthermore, shoulder pain can be a lesser-known symptom of lung cancer.

If you are experiencing any of these less common symptoms along with other concerning signs, it is essential to consult your doctor to rule out any underlying health conditions.


While the unusual signs discussed above may be important to watch for, it’s vital not to overlook the more common symptoms of lung cancer.

Being aware of these signs can help you identify potential problems early on and seek appropriate medical care.

The most common symptoms of lung cancer include:

1. Persistent or worsening cough: If you have a cough that lingers for an extended period or worsens over time, it could be a sign of lung cancer.

2. Coughing up blood or rust-colored phlegm: The presence of blood in your cough can be an alarming sign that warrants immediate medical attention.

3. Chest pain: Lung cancer can cause chest pain that worsens with deep breathing, coughing, or laughing.

4. Hoarseness: A persistent hoarse voice that doesn’t improve should be evaluated by a healthcare professional.

5. Loss of appetite and unexplained weight loss: Significant and unexplained weight loss, along with a reduced appetite, can be indicative of various health issues, including lung cancer.

6. Shortness of breath: If you find yourself becoming breathless more easily, even during light activities, it could be a symptom of lung cancer.


1. Fatigue and weakness: Feeling constantly tired and weak without a discernible cause might be a sign of an underlying health condition, including lung cancer.

2. Persistent infections: Frequent occurrences of bronchitis or pneumonia could be a result of lung cancer affecting the respiratory system.

3. New onset of wheezing: The development of wheezing or a change in existing wheezing patterns may indicate lung cancer.

4. Bone pain: Back or hip pain that persists, particularly if it worsens over time, can be associated with lung cancer spreading to the bones.

5. Changes to the nervous system: Headaches, weakness or numbness in the limbs, dizziness, balance problems, or seizures can occur if lung cancer spreads to the brain.

6. Yellowing of the skin and eyes (jaundice): Jaundice, characterized by yellowing of the skin and eyes, can be a sign that lung cancer has spread to the liver.

7. Swelling of lymph nodes: Enlarged lymph nodes in the neck or above the collarbone can be an indication of lung cancer.


Understanding the risk factors for lung cancer can help individuals assess their own susceptibility to the disease.

While smoking is the leading cause of lung cancer, accounting for over 70% of cases, it is essential to recognize that non-smokers can also develop this form of cancer.

The following factors increase the risk of developing lung cancer:

1. Smoking cigarettes: Smoking is the most significant risk factor for lung cancer. If you smoke, quitting is the most effective way to reduce your risk.

2. Smoking cannabis: Smoking cannabis, with or without tobacco, has been linked to an increased risk of lung cancer. The detrimental effects of smoking four joints are comparable to smoking 20 cigarettes.

3. Passive smoking: Even if you don’t smoke, exposure to secondhand smoke can still increase your risk of developing lung cancer.

4. Occupational exposure to harmful substances: Certain occupations, such as those involving exposure to radon gas, asbestos, arsenic, silica, coal, or nickel, can increase the risk of lung cancer.
5. Family history: Individuals with a family history of lung cancer may be at a higher risk due to genetic factors.

6. Age and gender: The risk of developing lung cancer increases with age, and men are more likely to develop the disease than women.

7. Radon exposure: Exposure to high levels of radon, a naturally occurring radioactive gas, can significantly increase the risk of lung cancer.


Unfortunately, recent research indicates that just over a third of people get their lungs checked when invited by the NHS. It is crucial to prioritize regular check-ups and be vigilant about any potential symptoms, as lung cancer may not always present immediately noticeable signs.

If you notice any of the symptoms associated with lung cancer, it is imperative to consult your doctor right away. While these symptoms may be indicative of other conditions, it is always better to err on the side of caution and undergo a proper medical evaluation.

Early detection of lung cancer significantly improves treatment outcomes and enhances the chances of successful recovery.

In addition to recognizing symptoms, it is equally important to understand the risk factors associated with lung cancer. By being aware of these factors, individuals can take proactive steps to reduce their chances of developing the disease.

The primary risk factor for lung cancer is smoking cigarettes. The harmful chemicals and carcinogens in tobacco smoke significantly increase the likelihood of developing lung cancer. Quitting smoking is the single most effective measure to reduce the risk of lung cancer.

It is worth noting that smoking cannabis, either mixed with tobacco or consumed independently, has also been linked to an increased risk of lung cancer.

The harmful effects of smoking marijuana can have similar consequences to smoking cigarettes, emphasizing the importance of avoiding or minimizing cannabis smoking.

Furthermore, individuals who are frequently exposed to secondhand smoke, also known as passive smoking, are at a heightened risk of developing lung cancer. It is essential to create smoke-free environments and limit exposure to cigarette smoke to protect both smokers and non-smokers alike.

Certain occupations pose an increased risk of lung cancer due to exposure to hazardous substances. Workers who regularly come into contact with radon gas, asbestos, arsenic, silica, coal, or nickel may have an elevated risk.

It is crucial for employers to prioritize occupational health and safety measures and provide appropriate protective equipment to minimize exposure to these harmful substances.

Family history can also play a role in determining an individual’s susceptibility to lung cancer. If there is a history of lung cancer in your family, it is important to discuss this with your healthcare provider, as they may recommend additional screening or monitoring.

While these risk factors can increase the chances of developing lung cancer, it is essential to remember that anyone can be affected by the disease, regardless of their smoking history or occupational exposure.

Therefore, it is crucial to remain vigilant and proactive about your health, even if you do not have any apparent risk factors.


In conclusion, recognizing the unusual signs of lung cancer, such as swollen fingers and changes in the nails, is critical for early detection and treatment.

Additionally, being aware of the more common symptoms, such as persistent coughing, chest pain, and shortness of breath, is essential. Although smoking remains the leading cause of lung cancer, non-smokers can also develop the disease due to various factors.

It is vital to prioritize regular check-ups, quit smoking, and create smoke-free environments to reduce the risk of lung cancer.

Remember, early detection saves lives, so if you notice any symptoms or have concerns about your lung health, consult with your healthcare provider promptly.

Consulting a healthcare professional is essential if any of these symptoms arise, as lung cancer can be treated more effectively when caught in its early stages.

Remember, understanding the risk factors and being proactive about your health is key to preventing and managing lung cancer
