In its initial stages, lung cancer is usually quiet and may not have any apparent warning symptoms. Lung cancer early symptoms (肺癌初期症狀) can result in an early diagnosis and more effective treatment of the disease. This guide presents the main red flags that can indicate the need to have a medical assessment.
Outlining the early warning signs of lung cancer that should not be ignored
Persistent cough that won’t go away
One of the most common early symptoms of lung cancer is a cough which lasts over three weeks. There is no improvement between coughs and it is more likely to get worse with time as opposed to typical cold or flu coughs. The cough could result either through dry cough or mucus coughing and could disrupt sleep. It is a symptom that many lung cancer patients present with at diagnosis. The important features of an alarming cough are:
- Lasts over three weeks: When a cough continues after that the duration it has lasted it should be looked at by a medical professional.
- Worsens over time: Makes the cough worse or more frequent instead of getting better.
- Disrupts sleep: A severe alert is coughing causing one to be awake at night.
- Dry or productive: It can be dry or can secrete phlegm or mucus.
- Occurs with chest pain: Pain upon coughing is an indication that it may be a lung problem.
Coughing up blood or blood-streaked sputum
Coughing with blood and even small volumes of blood are some serious warning symptoms that demand immediate medical state. The blood can be in the form of streaks in the phlegm or in larger proportions. The symptom is present when the tumour blood vessels are ruptured during coughing. It does not mean that it has to occur time and again, but it must not be overlooked.
Chest, back, or shoulder pain
Persistent pain in the chest, back or shoulders may be a result of lung cancer. The pain can either be a dull ache or sharp pains that are aggravated by deep breathing, coughing and laughing. This is the case where a tumour is pressing on nerves or going through the breast wall. In cases where pain is accompanied by other types of symptoms such as coughing or weight loss, then medical check up is needed.
Shortness of breath and wheezing
Part of the indication that could be an early sign of lung cancer is difficulty breathing or a sense of breathlessness during usual activities. This occurs because there is a tumour that obstructs or constricts an airway, impairing lung functions. Wheezing- high-pitched whistling sound during inhalation may also be experienced. The symptoms can be mild but as the disease advances, they get worse.
Loss of weight and fatigue without any known cause
Without any effort, considerable weight loss, and continuous fatigue can be the signs of lung cancer. Cancer cells eat up energy and have the capability to change metabolism which results in lack of appetite and loss of weight. Unexplained weight loss is common among the patients. Rest does not alleviate fatigue associated with cancer, and may disrupt daily routine.
