Lung cancer is one of the most common and serious cancers, leading in mortality, with about 2.09 million people developing the disease and 1.76 million deaths each year in the world. Therefore, early detection of symptoms of lung cancer is very important.

Early detection of lung cancer symptoms is important, however, signs and symptoms of lung cancer usually do not appear at an early stage, but as the disease progresses, the signs can become clearer.

The symptoms do not tend to show until the disease progresses, but the UK's Lung Castle Lung Cancer Foundation says that even if the symptoms appear, there are some signs that may still not be noticeable.

A noticeable sign may appear on the face, but many people may not realize it. It is Face swelling:.

  • Face swelling

Many people think that a swollen face is caused by allergies. However, facial swelling may be due to obstruction of the superior vena cava, usually due to lung cancer.

The superior vena cava is the large vein in the chest, carrying blood from the upper half of the body to the heart. When the superior vena cava is blocked, blood flow from the heart and upper body is blocked.

The cause is usually a lung cancer tumor located near a vein. The tumor may compress into a vein or may have spread to nearby lymph nodes. This blockage then causes the face to swell.

In addition, there are other places on the body that can also be swollen, which are:

  • Neck swelling 

In addition to causing  face swelling, lung cancer tumors can also cause neck swelling.

  • Fingertip swelling 

Another symptom that many people may not realize is swelling of the fingertips, called drumstick finger syndrome.

The fingers become more curved or the tips of the fingers become larger like drumsticks. Drumstick fingers syndrome is a clear sign of lung cancer and lung cancer is the most common reason for this drumstick finger.

This syndrome often appears in heart and lung diseases when the amount of oxygen in the blood is reduced.

The UK National Health Service Agency points out other symptoms to watch out for:

  • Anorexia, nausea and weight loss
  • Cough does not go away after 2-3 weeks
  • Cough persistent, getting worse
  • Recurrent pneumonia
  • Hemoptisi
  • Pain while breathing or coughing
  • Persistent breathing difficulties
  • Prolonged fatigue or lack of energy

If you experience any of these symptoms, see a doctor immediately. Less common symptoms include: Difficulty swallowing or pain when swallowing, wheezing, hoarseness, persistent chest or shoulder pain
