Chest pain with breathing is a common symptom of advanced lung cancer, primarily due to the invasion of cancerous cells into the lung tissue and the surrounding structures. As the tumor grows, it can irritate the pleura (the lining of the lungs), which leads to discomfort or pain during respiration. Additionally, if the cancer spreads to other areas such as the chest wall or causes pleural effusion (fluid accumulation in the pleural space), it can exacerbate pain symptoms. The presence of tumors or metastases can also affect the integrity of the lung tissues and the structures involved in breathing, leading to further discomfort.

In contrast, increased energy levels would generally not be associated with advanced lung cancer, as patients tend to experience fatigue due to the body's response to cancer and potential weight loss. Hypertension is not a primary symptom directly linked to lung cancer, as it relates more to cardiovascular conditions or other systemic issues. Lastly, new hair growth is unlikely to be associated with lung cancer, as patients with advanced disease may experience other effects related to their overall health and treatment processes, such as hair loss due to chemotherapy. Thus, chest pain during breathing is a significant symptom that warrants further investigation in patients with suspected advanced lung cancer.
