Many of the cancer patients describe a constant, aching, and sometimes sharp pain. In some cases, it can be the first sign that appears. The pain is usually located in the ear and temporal region, and occasionally the jaw. In some reports, patients have described “attacks of debilitating facial pain”, presenting as cluster headaches. It may worsen when a person is lying down or raising both arms.
The researchers noted that pain can, on rare occasions, be the presenting symptoms of lung cancer. A 2018 case study describes the experience of one person who approached a dermatologist about swelling around the eyes and a feeling of swelling in the face and throat. Diagnostic tests showed that the person had small-cell lung cancer (SCLC).
