2. Chest Pain
Since there can be so many serious reasons for having chest pain, including heart issues, it’s important to always get this problem checked out right away, says Dr. Pennell. It’s not common, but lung cancer can be a cause. The American Cancer Society describes lung cancer-related chest pain as “often worse with deep breathing, coughing, or laughing.” It may feel like a dull, persistent ache.
Unfortunately, feeling chest discomfort from cancer is “usually a sign that it’s become quite advanced,” explains Dr. Pennell, and already invaded the pleura or bones around your chest.
