Oncologists have named a new unusual symptom of lung cancer

Lung cancer is one of the most serious and dangerous types of cancer. Its symptoms include continuous coughing, including with blood, difficult and painful breathing. Lung cancer is the most difficult to diagnose, so the prospects for its successful treatment are not the best.

However, the tumor is treatable if its symptoms are noticed in time. The main danger of any type of cancer is the hidden signs of the disease, due to which the patient does not even know about it. One of these symptoms is the color of saliva.

According to oncologists, the development of a tumor can be recognized if the sputum is red or brown when expectorated. Sputum is a mixture of saliva and mucus that accumulates in the respiratory tract, which is also released in bronchitis or asthma.

Among other signs of lung cancer are chest pains that worsen with deep breathing, fatigue, weight loss, swelling of the face and swollen fingertips.
