Lung cancer is one of the most common types of cancer. In the early stages, this disease rarely makes itself felt. Most cases of the disease are detected after the age of 40, half of them occur in patients older than 75 years. The most common cause is smoking, accounting for more than 70% of all diagnosed cases.

Symptoms may include a persistent cough and shortness of breath. However, there are five more non-obvious signs of lung cancer:

• changes in the nails. Some patients with lung cancer note that the tips of the nails begin to bend down more than usual;
• pain in the arm or shoulder. This symptom can be caused by a certain type of lung cancer if it spreads to the nerves;
• slight changes in the voice. He may become more hoarse than usual. In addition, a person may begin to make sounds that he is not used to, according to Cancer Care Centers of Brevard;
• lowered eyelids. This can be a neurological symptom of lung cancer, in which nerves are compressed;
• constant thirst and frequent urination. This symptom is reported in up to 20% of patients with the disease.

Other common symptoms of lung cancer include coughing up blood or excess mucus and chest pain. To reduce the risk of the disease, doctors recommend quitting smoking, eating more vegetables and fruits every day, and exercising at least 150 minutes a week.
