He/she should go to the doctor to find out.
There are two main types of lung cancer:

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer.
Small cell lung cancer makes up about 20% of all lung cancer cases.
If the lung cancer is made up of both types, it is called mixed small cell/large cell cancer.

If the cancer started somewhere else in the body and spread to the lungs, it is called metastatic cancer to the lung.

Symptoms depend on the specific type of cancer you have, but may include:

Cough that doesn't go away
Coughing up blood
Shortness of breath
Wheezing
Chest pain
Loss of appetite
Losing weight without trying
Fatigue
Additional symptoms that may also occur with lung cancer:

Weakness
Swallowing difficulty
Nail problems
Joint pain
Hoarseness or changing voice
Swelling of the face
Facial paralysis
Eyelid drooping
Bone pain or tenderness
These symptoms can also be due to other, less serious conditions, so I suggest you talk to your health care provider.
Coughing
Fatigue
Some wrinkles may appear
Darkened Lungs
Constant Chills
Drowsiness
