Chronic Back Pain: Should You Get Blood Tests for Cancer? - Oncology

Chronic back pain can be a frustrating and debilitating condition, and it's understandable to be concerned about the possibility of serious underlying issues, including cancer. However, it's important to approach this situation with a clear understanding of what blood tests can and cannot reveal regarding cancer.

First, let's address the nature of your back pain. Chronic back pain can arise from various causes, including muscle strain, ligament sprains, herniated discs, or degenerative conditions such as arthritis. In your case, you've already undergone X-rays and an MRI, which have not indicated any serious structural issues. The slight nerve compression noted by your neurologist could explain your symptoms, including the numbness in your legs.
Regarding your concern about blood tests for cancer, it's essential to recognize that routine blood tests are not typically used as a screening tool for cancer in individuals who do not exhibit specific symptoms or risk factors. While certain blood tests can indicate the presence of cancer, they are not definitive. For example, elevated levels of specific markers (like CEA for colorectal cancer or CA-125 for ovarian cancer) can suggest the presence of cancer, but they can also be elevated due to non-cancerous conditions.
In your friend's case, the discovery of a "white spot" on an X-ray that led to a diagnosis of blood cancer is an example of how imaging studies can sometimes reveal concerning findings that warrant further investigation. However, this does not mean that everyone with chronic back pain should undergo extensive cancer screening. The key is to evaluate your symptoms in the context of your overall health and medical history.

Since you have already had blood tests that ruled out ankylosing spondylitis (a type of inflammatory arthritis that can cause back pain), and given that your pain has persisted despite conservative measures like stretching and swimming, it may be prudent to consult with a specialist, such as a rheumatologist or an orthopedic surgeon. They can assess your condition more thoroughly and determine if further imaging or specific blood tests are warranted based on your symptoms and physical examination.

If you are experiencing new symptoms, such as unexplained weight loss, persistent fatigue, or changes in bowel or bladder habits, these could be red flags that warrant further investigation. In such cases, your healthcare provider may recommend additional tests, including blood tests or imaging studies, to rule out serious conditions, including cancer.

In summary, while your concerns about cancer are valid, especially given your friend's experience, it is crucial to approach this matter with a balanced perspective. Chronic back pain is common and often related to musculoskeletal issues rather than cancer. If you have specific concerns or new symptoms, discussing them with your healthcare provider is the best course of action. They can guide you on whether further testing is necessary based on your individual situation. Regular follow-ups and open communication with your healthcare team are key to managing your health effectively.
