Neuroendocrine Tumors: Why They Are Called The ‘Hidden Cancers’

Introduction

Neuroendocrine tumors are rare growths that start in cells linking the nervous and hormone systems. These tumors can appear in many body parts, such as the lungs, pancreas, or digestive tract. Because they often grow slowly and cause mild or vague symptoms, doctors sometimes call them “hidden cancers.” As a result, many people do not know they have a neuroendocrine tumor until it is advanced. Early detection is important, but it can be tricky.

Symptoms

At first, neuroendocrine tumors may not cause any signs. However, as they grow, some symptoms may appear. Early symptoms of neuroendocrine tumors can be mild and easy to miss. For example, you might notice:

Unexplained weight loss

Stomach pain or discomfort

Flushing or redness of the skin

Diarrhea or changes in bowel habits

Feeling tired or weak

Wheezing or coughing (if in the lungs)

Still, these symptoms can look like other common health problems. Therefore, many people do not seek help right away.

Causes and Risk Factors

Doctors do not always know what causes neuroendocrine tumors. Yet, some factors can raise your risk. For instance, you may be more likely to develop these tumors if you:

Have a family history of certain genetic conditions (like MEN1 syndrome)

Are older, as risk increases with age

Have other health issues, such as diabetes or stomach problems

Smoke or use tobacco products

Even so, many people with neuroendocrine tumors have no clear risk factors.

Diagnosis

Because symptoms are often mild, the diagnosis of neuroendocrine tumors can take time. Doctors may use several tests to find these tumors. For example, they might order:

Blood and urine tests to check for certain hormones

Imaging scans, such as CT, MRI, or PET scans

Biopsy, where a small tissue sample is examined

Sometimes, doctors find neuroendocrine tumors by accident during tests for other issues. According to the World Health Organization (WHO), early diagnosis can improve outcomes.

Treatment Options

Treatment for neuroendocrine tumors depends on the tumor’s size, location, and stage. Your doctor may suggest one or more of these options:

Surgery to remove the tumor

Medications to control hormone levels

Chemotherapy or targeted therapy

Radiation therapy

In some cases, doctors use a mix of treatments. However, each plan is tailored to the patient’s needs.

Why Neuroendocrine Tumors Are Often Missed

Neuroendocrine tumors are called “hidden cancers” for several reasons. First, their symptoms can be vague and slow to appear. Second, these signs often look like other, less serious problems. Third, the tumors may grow in places that are hard to check. Because of this, many people are diagnosed at a later stage. Early symptoms of neuroendocrine tumors are easy to overlook, which adds to the challenge.

Prevention and Lifestyle Guidance

While you cannot always prevent neuroendocrine tumors, some healthy habits may lower your risk. For example:

Do not smoke or use tobacco

Eat a balanced diet rich in fruits and vegetables

Exercise regularly

Manage chronic health conditions with your doctor’s help

Additionally, knowing your family history can help you and your doctor watch for early signs.

When to See a Doctor

If you notice ongoing symptoms like unexplained weight loss, stomach pain, or changes in bowel habits, see your doctor. Even though these signs may not mean cancer, it is better to check. Early diagnosis of neuroendocrine tumors can lead to better treatment results. Therefore, do not ignore symptoms that last more than a few weeks.
