No Symptoms of Early Lung Cancer? Multi-symptom Emerge is the Key
Lung cancer is usually asymptomatic in the early stage, and lung cancer patients with symptoms are more likely to be caused by other physical problems. Some people may even be misdiagnosed as general pneumonia, cold, or allergies. This article will introduce the precursors of lung cancer symptoms, please pay more attention. The American Lung Association also reminds patients that if they feel anything wrong, they can express their views and thoughts during the consultation, help doctors make correct medical judgments, and thus improve the success rate of lung cancer treatment. After all, only you know your body best.
Why are there no symptoms in the early stage of lung cancer?
The reason why lung cancer has no symptoms in the early stage is because there are few nerve endings in the lungs. The reason why people feel pain and other discomfort symptoms is because of the physical response triggered by the nerve lines, so lung tumors can grow without causing any pain or discomfort. In this regard, the Lung Cancer Foundation of America pointed out that many early diagnoses of lung cancer are accidentally discovered during non-lung cancer detection and screening.
Possible Lung Cancer Symptoms
The following is a list of lung cancer symptoms that patients may have. The symptoms may vary from person to person. Please note that if there is only one of the symptoms mentioned, there is no need to worry too much. Be sure to consult your physician for further investigation.
Symptoms and 9 precursors of lung cancer
-
- Cough, hoarseness that persists for more than three weeks, or gradually worsens, or changes in a long-standing cough
- Chronic cough
- Chest pain,
- Weight loss
- Coughing up blood (watch out for even a small amount), or rust-colored phlegm.
- Persistent chest or shoulder pain that gets worse when you cough, laugh, or take a deep breath.
- Wheezing or difficulty breathing for no reason.
- Frequent or recurring lung infections, including symptoms like pneumonia, emphysema, or bronchitis.
- Fatigue or weakness.
When cancer cells metastasize to other parts of the body, the following symptoms of lung cancer may occur
-
- Pain or a broken bone, such as in the back or hip.
- Thrombus.
- No appetite.
- Unexplained weight loss.
- Lung cancer spreads to the brain, causing changes in the nervous system. Symptoms include headaches, dizziness, seizures, weakness or numbness in the hands and feet, and balance disturbances.
- Lung cancer metastasizes to the liver, causing jaundice.
- Swollen lymph nodes, like in the neck or above the collarbone.
Possible lung cancer syndrome
Also note that some lung cancers can cause other syndromes, including the following three symptoms. However, most of these symptoms are not symptoms of lung cancer, but likely to be caused by other physical problems. If you have any questions, please consult a professional doctor for early diagnosis and treatment.
1. Horner’s syndrome
When lung cancer is in the upper part of the lung, or a Pancoast tumor, it can affect some nerves that connect to the eyes and parts of the face, causing Horner’s syndrome. It is worth noting that Pancoast tumors are more likely to be Non-Small Cell Lung Cancer, and sometimes cause severe shoulder pain.
2. Superior vena cava syndrome
The superior vena cava is a large blood vessel responsible for carrying blood from the head and hands to the heart. It passes through the upper part of the right lung and the lymph nodes in the chest. When a lung tumor grows in this area, it will cause a squeeze of blood. Pressure, this is the superior vena cava syndrome (Superior Vena Cava syndrome). Symptoms include swelling of the face, neck, arms, upper chest, possibly bruising in the chest, and if the brain is affected, headaches, dizziness, and altered consciousness.
3. Syndrome with tumor
Some lung cancers secrete hormonal substances, causing them to invade the patient’s blood and cause health problems in distant tissues and organs, but in fact, the cancer cells have not metastasized to the site. This disease is called Paraneoplastic syndrome. This is a syndrome that can occur in any type of lung cancer, but it is most common in small cell lung cancer. Sometimes, it may appear as early lung cancer symptoms, resulting in misdiagnosis.

In terms of lung cancer types, there are two major categories: small cell lung cancer and non-small cell lung cancer. Cancer cells of each type grow and spread in a different way, and they are treated in a different way as a result of this.

Air Purifier Can Reduce the Risk of Lung Cancer
The use of air purifiers in naturally ventilated residences can reduce the total cancer risks associated with several common indoor SVOCs, particularly DEHP. It is best for the air purifier to have a HEPA-grade filter, which can filter at least 90% of the dirty air; the filter made of activated carbon can filter out odors, and you can also pay more attention to it; and many purifiers will also focus on negative ions. It can combine with PM2.5 and settle down to the ground, which can be removed when cleaning; while photocatalyst is beneficial to remove most bacteria, which is beneficial to environmental purification
