Cough, flu... lasting. Wa.rning: 4 signs of lung can.cer that are often overlooked because they are thought to be "minor il.lne.sses"

Lung can.cer, partly due to its symptoms often being misdiagnosed, tends to be detected late. The initial signs of the disease resemble common symptoms like a cold, regular coughing, or minor health issues that people tend to ignore. Patients may underestimate the severity of these symptoms, missing the golden opportunity to detect and treat the disease in its early stages.

Lung can.cer occurs when lung cells grow abnormally, uncontrollably, forming tumors that may spread to other parts of the bo.dy.

The disease can develop silently over many years without clear symptoms, making early detection a major challenge.

1.  Persistent Cough

Coughing is a common symptom of many respiratory diseases, ranging from a simple cold, sore throat, to asthma. However, if you have a persistent cough lasting more than three weeks, especially without a feeling of fever or flu, this could be a sign of lung cancer.

However, many people tend to ignore this symptom, thinking it’s just a reaction of the body to weather changes or environmental pollutants. Using cough medicine without checking the real cause can allow the disease to silently progress.

Cough, flu, shortness of breath, chest pain... if these symptoms persist, it’s important to see a doctor early.

2.  Shortness of Breath or Difficulty Breathing

Sudden shortness of breath or difficulty breathing, especially when doing normal activities like climbing stairs or carrying light loads, could be an alarming sign. However, many people believe this is caused by fatigue, age, or laziness.

In reality, as tumors grow in the lungs, they can block the airways, leading to breathing difficulties. This condition becomes more serious if the person has a history of smoking or works in environments exposed to ha.rmful chemicals.

3.  Chronic Ch.est P.ain

A persistent sharp, tight, or dull pain in the chest area is one of the early signs of lung cancer.

However, this pain is often mistaken for other conditions like muscle pain, intercostal nerve pain, or heart-related symptoms.

If the pain is unrelated to physical activity and progressively worsens, you should see a doctor immediately.

4.  Sudden Weight Loss Without Known Cause

Unexplained weight loss, despite no change in diet or exercise habits, is a "silent" symptom that many people overlook.

In lung cancer, weight loss often occurs because cancer cells use the body’s energy or due to the influence of cytokines, inflammatory substances produced by the body to fight the tumor.

If you notice sudden weight loss along with persistent fatigue, loss of appetite, be alert and see a doctor.

Lung can.cer is not a disease that can be easily prevented or treated, but the important thing is to recognize early warning signs to intervene promptly.

Symptoms like persistent cough, shortness of breath, chronic chest pain, or sudden weight loss should not be dismissed or attributed to common causes.

Listen to your bo.dy, maintain regular health check-ups, and seek medical advice if any abnormalities occur.
