Lung cancer at your age would be at the bottom of the list of possibilities. Cough is a protective reflex the lung uses to move debris from deeper in the lung to expel it. It is the common response to simple accumulation of mucus with colds or exposure to lung irritants. If you are loosing sleep over this get checked out.

A dry cough can be attributed to so many different factors, including mouth breathing and dry (vs humid) air. Unless you are a heavy smoker for years, the chances of your concerns being real are minuscule. For peace of mind if you are that concerned, be evaluated by your physician since this cannot be diagnosed over the internet.

Cancer is highly unlikely. You may watch and wait. If cough lasts more than 2 weeks, it would be useful to see a pulmonologist/lung doctor. Wish you good health!
