Lung cancer: three symptoms that may go unnoticed

0

Lung cancer symptoms can be confusing with manifestations of less serious diseases. This type of cancer is usually difficult to detect in the early stages. Often, patients are treated for other diseases for a long time by doctors of other specialties. Most often, the first symptoms of lung cancer are often not related to the respiratory system.

External changes, as well as internal sensations, can tell about the disease. According to the Cancer Treatment Centers of America, some patients develop swelling on the face or neck.

The patient may also have difficulty swallowing food. Or he begins to feel unusual pain when swallowing.

The third unexpected symptom of lung cancer is a change in the appearance of the fingers. The tips of the fingers sometimes become thicker than the phalanges by analogy with drumsticks. Nails can also bend, taking the shape of fingers and resembling frosted white glass.

Other signs of lung cancer:

• feeling tired without physical exertion;
• unexplained back pain;
• hoarse voice;
• coughing up blood;
• headaches and dizziness;
• muscle pain.
