Which part of the back hurts in lung cancer?

Lung cancer is a very common disease. The vast majority of lung cancers originate from the epithelium of the bronchial mucosa, hence the term “bronchogenic carcinoma.” Lung cancer is also one of the most dangerous malignant tumors, with the fastest-growing incidence and mortality rates; among male cancer patients, it ranks first in prevalence. So, which part of the back hurts when someone has lung cancer? Below, we address this question.

Which part of the back hurts in lung cancer?

Typically, back pain caused by lung cancer occurs in the upper portion of the back. As a malignant tumor of the respiratory system, lung cancer commonly presents with symptoms such as cough, sputum production, and blood-tinged sputum. Therefore, it is crucial to remain vigilant and recognize these warning signs, as early detection and timely treatment significantly improve outcomes. Cough is the initial symptom in 35%–75% of cases. When a lung tumor is located near the pleura, it may cause irregular, dull pain—including persistent chest pain—and localized, fixed tenderness if the tumor invades the ribs or spine. Additionally, if the tumor compresses nearby lymph nodes, deep-seated retrosternal pain may occur, often accompanied by intermittent chest pain and hemoptysis (blood in sputum).

Knowledge Extension: What are the main causes of lung cancer?

1. Long-term smoking

Research shows that cigarette smoke contains over 200 carcinogens. Male smokers face a 4- to 10-fold higher risk of developing lung cancer than female smokers; for heavy smokers with more than 20 years of smoking history, the risk increases 10- to 20-fold. Secondhand smoke exposure also elevates lung cancer risk, and its associated incidence has risen markedly in recent years.

2. Environmental pollution

In industrially developed regions—particularly those involved in coal and petroleum production—the combustion of these fuels releases benzene-containing hazardous substances, leading to environmental contamination. Prolonged residence in such polluted environments results in chronic inhalation of harmful substances, causing symptoms like coughing and, in severe cases, blood-streaked or frank hemoptysis. Over time, this damages the lungs and increases the risk of developing lung cancer.

The above outlines which areas of the back may hurt in lung cancer. We hope this information is helpful to you.
