How Lung Cancer and Back Pain are Co-Related? 

On the surface, back pain and lung cancer may not seem to be connected to medical issues. However, a closer look reveals several ways in which they may be interconnected. Chest pain, dyspnea, and a persistent cough are common symptoms of lung cancer, which is one of the world’s most common causes of cancer-related fatalities. The connection between lung cancer and back discomfort is less well-known but very important. Multiple factors may give birth to this relationship, such as the tumor’s direct physical impact, its metastatic spread to the bones, paraneoplastic syndromes, or even the side effects of cancer therapy. To improve patient outcomes and quality of life, it is imperative to comprehend the pathways through which back pain can be caused by lung cancer and to diagnose the disease as soon as possible. 

In the current blog, we will see how back pain can be connected to lung cancer, and which signs and symptoms should be taken seriously to diagnose lung cancer at early stages. 

Signs and symptoms 

In certain cases, back discomfort may indicate lung cancer, particularly if it is continuous and accompanied by other distinct symptoms. The following list of signs suggests that lung cancer and back discomfort may be related: 

Symptoms and Indices of Prolonged Back Pain: 

  • Conventional therapy or rest does not alleviate the pain. 
  • It is persistent and getting worse over time. 
  • Related Symptoms of the Respiratory System 
  • Persistent cough, particularly if it is evolving or new. 
  • Breathing difficulty or wheezing. 
  • Spitting blood (hemoptysis) out. 
  • Symptoms related to the constitution 
  • Unaccounted-for weight loss. 
  • Appetite decline 
  • a generalized weakness or exhaustion.
Local Symptoms

Radiating pain to the chest, arm, or shoulder. 

soreness that gets worse when you laugh, cough, or breathe deeply.

Symptoms related to the nervous system

Arms or legs that are numb, feeble, or tingly. 

inability to walk or stay balanced. 

modifications to bowel or bladder function, which could be a sign of spinal cord compression.

Bone Aches

Severe discomfort in particular bones, which could be a sign of metastases. 

soreness or edema surrounding the bones.

Hazard Contributors

Smoking history: One of the main risk factors for lung cancer. 

Exposure to carcinogens: Industrial chemicals, radon, asbestos, etc. 

Lung cancer in the family: genetic predisposition might be involved. 

Age: People 50 years of age and older have a higher frequency.

Lung cancer can induce back discomfort by a variety of methods, including direct tumor effects, metastatic dissemination, and secondary consequences.

Here is a detailed look at how lung cancer can cause back pain. 
  1. Direct Tumor Effects
    Tumor Growth and strain: As the lung tumor progresses, it can put a strain on neighboring structures such as the spine, ribs, and nerves. This pressure might produce localized pain, which can spread to the back. 
  1. Spinal bone metastasis
    Metastasis: Lung cancer can migrate to bones, particularly the vertebrae in the spine. This metastatic spread can weaken bones, resulting in discomfort, fractures, and structural instability.
    Spinal Cord Compression: When metastatic tumors grow in or near the spine, they can compress the spinal cord or nerve roots, causing severe back pain and neurological symptoms like numbness, paralysis, and loss of bladder and bowel control. 
  1. Paraneoplastic syndromes
    Paraneoplastic syndromes are illnesses produced by the immune system’s response to cancer. Some lung tumors create hormone-like compounds or cause immunological reactions that influence the musculoskeletal system, resulting in widespread muscle and bone discomfort, especially in the back. 
  1. Secondary Complications of Treatment
    Radiation Therapy: Radiation treatment for lung cancer can cause inflammation and damage to the tissues surrounding the treatment location, including the back, resulting in anguish. 

Chemotherapy: Some chemotherapy medicines can cause bone pain or peripheral neuropathy (nerve damage), which can lead to back discomfort. 

Pancoast Tumor: A kind of lung cancer that begins at the top of the lung (in the superior sulcus) and can spread to surrounding structures such as the brachial plexus, spine, and ribs, causing significant shoulder and back pain. 

Diagnoses and Tests: 

Imaging studies include chest X-rays. 

Initial screening for lung problems. 

Computed Tomography (CT) Scan 

Provides detailed cross-sectional pictures of the lungs and their surrounding structures. 

Identifies the size, form, and location of lung tumors, as well as their potential dissemination to the spine. 

Magnetic resonance imaging (MRI) 

Soft tissues, including the spine and spinal cord, are imaged in detail. 

Assesses spinal metastases and nerve root involvement. 

Positron Emission Tomography (PET) Scan 

Detects areas with elevated metabolic activity, which may indicate malignancy. 

PET scans are frequently used in conjunction with CT scans to identify aggressive cancer areas. 

  • Bronchoscopy 

Flexible tube with a camera and equipment for collecting samples from the lungs. 

  • Needle aspiration 

CT or ultrasound is used to guide the collection of tissue samples from the lung or metastatic locations. 

  • Surgical biopsy 

Needle Aspiration. 

Tissue samples from the lung or metastatic areas are collected under the guidance of CT or ultrasound. 

Bone Scans 

Detects bone metastases. 

Radioactive material is injected and accumulates in areas of high bone activity, which is then visualized using a specific camera. 

Blood Tests

A complete blood count (CBC) can reveal anemia and other blood disorders. 

Tumor markers 

Specific proteins may be raised in some types of lung cancer (for example, carcinoembryonic antigen, or CEA). 

Pulmonary Function Tests (PFTs) evaluate lung function to determine tumor impact on breathing. 

Provides baseline data for treatment planning. 

Neurological Examination 

Assesses neurological impairments induced by spinal cord compression or nerve involvement. The implications for intervention planning. 

Genetic and Molecular Testing 

Identifies particular genetic mutations or indicators in cancer cells. 

Guides focused remedies and personalized treatment regimens. The implications for intervention planning. 

Pulmonary Function Tests

(PFTs) evaluate lung function to determine tumor impact on breathing. 
Provides baseline data for treatment planning. 


Finally, lung cancer and back pain are tightly associated with a variety of processes. The physical growth of lung tumors, particularly those on the top of the lung (Pancoast tumors), can directly push on the spine and accompanying nerves, resulting in back pain. Furthermore, lung cancer frequently metastasizes to the bones, including the spine, producing severe discomfort and potentially resulting in spinal cord compression and neurological problems. Paraneoplastic disorders and treatment-related adverse effects can also lead to musculoskeletal discomfort. So, it is important to consider all these factors. If you have any family history of lung cancer or notice any of the symptoms don’t take the risk of ignoring any of these.
