Most cancer researchers believe that 20 or more years pass from the time that a person starts to inhale a cancer-producing substance, such as tobacco smoke, and the time cancer actually develops.
Lung cancer is very difficult to detect at an early stage. Because of the large size of the lungs, cancer may grow for many years without any symptoms. Symptoms of lung cancer (e.g., persistent cough, etc.) do not always appear in the early stages of lung cancer.

Lung cancer: Hormonal (endocrine) syndromes
Certain types of lung cancers are capable of producing hormones that act on organs within the brain (the pituitary and hypothalamus) or upon other organs such as the kidneys, adrenal glands, thyroid, ovaries, or testes.
• Syndrome of inappropriate antidiuretic hormone (SIADH), resulting in low levels of sodium in the blood, often is associated with small cell lung cancer and sometimes bronchial carcinoid tumors.
