Signs of Multiple Myeloma

Multiple myeloma is a rare but serious type of blood cancer that develops in plasma cells, a type of white blood cell found in the bone marrow. These cells normally help your immune system by producing antibodies that fight infections. However, in multiple myeloma, abnormal plasma cells multiply uncontrollably and crowd out healthy blood cells, weakening the immune system and damaging bones, kidneys, and other organs.

One of the biggest challenges with this disease is that its symptoms often appear gradually. Many people mistake the early warning signs for aging, arthritis, or general fatigue, which can delay diagnosis. Recognizing the signs of multiple myeloma early is important because prompt treatment can help manage symptoms, prevent complications, and improve quality of life.

This guide explains everything you need to know about multiple myeloma, including what is the first sign of multiple myeloma, causes of multiple myeloma, stages of multiple myeloma, multiple myeloma treatment, multiple myeloma prognosis, and whether multiple myeloma is hereditary.

What Is Multiple Myeloma?

Multiple myeloma is a cancer that begins in plasma cells located in the bone marrow. Healthy plasma cells produce antibodies that protect the body against infections. When these cells become cancerous, they multiply rapidly and produce abnormal proteins known as M proteins.

These abnormal proteins do not fight infections. Instead, they build up in the blood and can damage the kidneys, weaken the bones, reduce the production of healthy blood cells, and increase the risk of infections. As these complications develop, many of the signs of multiple myeloma—such as persistent bone pain, fatigue, anemia, kidney problems, and frequent infections—begin to appear and may gradually worsen without timely diagnosis and treatment.

Unlike many other cancers, multiple myeloma usually affects several areas of the bone marrow at the same time, which is why it is called “multiple” myeloma.

What Is the First Sign of Multiple Myeloma?

One of the most common questions people ask is, what is the first sign of multiple myeloma?

There is no single symptom that appears in every patient. However, persistent bone pain is often the earliest warning sign. The pain usually affects the back, ribs, hips, or shoulders and may worsen with movement or at night.

Other early symptoms may include:

• Persistent fatigue
• Weakness
• Frequent infections
• Unexplained weight loss
• Mild anemia
• Tingling or numbness
• Increased thirst
• Frequent urination

Some individuals have no symptoms at all during the early stages. In such cases, the disease may be discovered during routine blood tests that show abnormal protein levels or anemia.

Early Signs of Multiple Myeloma

1. Persistent Bone Pain

Bone pain is the most common symptom of multiple myeloma. Unlike muscle soreness, this pain does not improve with rest and often becomes worse over time.

Common areas include:

• Spine
• Lower back
• Ribs
• Pelvis
• Shoulders
• Hips

The pain occurs because cancer cells weaken the bones, making them more fragile.

2. Fatigue and Weakness

As abnormal plasma cells replace healthy bone marrow, fewer red blood cells are produced. This leads to anemia, which causes:

• Constant tiredness
• Weakness
• Dizziness
• Shortness of breath
• Difficulty performing daily activities

Many people assume they are simply overworked or aging, delaying medical evaluation.

3. Frequent Infections

Healthy plasma cells produce antibodies that protect the body from bacteria and viruses. Cancerous plasma cells cannot perform this function properly, increasing the risk of:

• Pneumonia
• Sinus infections
• Urinary tract infections
• Influenza
• COVID-19 complications
• Skin infections

If you experience repeated infections within a short period, consult a healthcare provider.

4. Bone Fractures

Multiple myeloma weakens bones by activating cells that break down bone tissue. Even minor injuries may result in fractures.

Common fracture sites include:

• Spine
• Hip
• Ribs
• Arms

Some patients discover they have multiple myeloma only after suffering an unexpected fracture.

5. Kidney Problems

Abnormal proteins produced by myeloma cells can damage the kidneys over time.

Symptoms may include:

• Swollen legs
• Reduced urine output
• Foamy urine
• Fatigue
• Elevated creatinine levels

Kidney damage can become severe if left untreated.

6. High Calcium Levels

When bones break down, calcium is released into the bloodstream.

High calcium levels (hypercalcemia) can cause:

• Extreme thirst
• Frequent urination
• Nausea
• Constipation
• Confusion
• Drowsiness
• Loss of appetite

Hypercalcemia requires immediate medical treatment.

7. Weight Loss

Unexpected weight loss is another warning sign of many cancers, including multiple myeloma.

Patients may notice:

• Reduced appetite
• Muscle loss
• Fatigue
• Low energy levels

8. Numbness and Tingling

Collapsed vertebrae may compress spinal nerves.

Symptoms include:

• Tingling in the legs
• Weakness
• Difficulty walking
• Loss of sensation

This may indicate spinal cord compression and requires urgent evaluation.

Common Symptoms of Multiple Myeloma

Doctors often use the CRAB criteria to identify organ damage caused by multiple myeloma.

C – Calcium Elevated

High calcium due to bone destruction.

R – Renal Failure

Kidney damage caused by abnormal proteins.

A – Anemia

Reduced production of healthy red blood cells.

B – Bone Disease

Bone pain, fractures, and osteoporosis.

CRAB Symptoms and Warning Signs of Multiple Myeloma

Doctors often use the CRAB acronym to identify the major signs of organ damage caused by multiple myeloma. If one or more of these features are present, they may indicate that the disease is active and requires prompt medical evaluation and treatment.

CRAB Feature	What It Means	Common Symptoms
C – High Calcium (Hypercalcemia)	Bone destruction releases excess calcium into the bloodstream.	Excessive thirst, frequent urination, nausea, constipation, confusion, and fatigue.
R – Renal Problems (Kidney Damage)	Abnormal proteins produced by myeloma cells can damage the kidneys.	Swelling in the legs, reduced urine output, elevated creatinine levels, and kidney failure.
A – Anemia	Cancer cells reduce the production of healthy red blood cells in the bone marrow.	Persistent fatigue, weakness, dizziness, shortness of breath, and pale skin.
B – Bone Lesions (Bone Disease)	Myeloma weakens bones, making them fragile and more likely to fracture.	Bone pain, osteoporosis, spinal compression, loss of height, and unexpected fractures.

Why the CRAB Criteria Matters:
The CRAB criteria help doctors recognize when multiple myeloma is causing significant organ damage. Identifying these warning signs early allows healthcare providers to begin appropriate treatment, reduce complications, and improve patient outcomes.

Causes of Multiple Myeloma

The exact causes of multiple myeloma remain unknown. Scientists believe the disease develops due to genetic changes within plasma cells, but several factors may increase the risk.

These include:

• Age over 60 years
• Male gender
• African ancestry
• Family history
• Obesity
• Radiation exposure
• Exposure to certain industrial chemicals
• History of MGUS (Monoclonal Gammopathy of Undetermined Significance)

Most people diagnosed with multiple myeloma have no obvious cause.

Is Multiple Myeloma Hereditary?

Many patients wonder, is multiple myeloma hereditary?

In most cases, the answer is no. Multiple myeloma is generally not inherited from parents.

However, having a close relative with multiple myeloma or MGUS may slightly increase the risk. Researchers believe genetics play a role, but environmental and lifestyle factors are also involved.

Routine genetic screening is not recommended unless advised by a specialist.

Who Is Most at Risk?

Several factors may increase the risk of developing multiple myeloma and experiencing the signs of multiple myeloma, including:

• Older adults
• Men
• African ancestry
• Obesity
• Family history
• MGUS
• Radiation exposure
• Chemical exposure

Having one or more risk factors does not necessarily mean someone will develop the disease.

Stages of Multiple Myeloma

The stages of multiple myeloma are determined using the Revised International Staging System (R-ISS).

Stage I

• Early disease
• Low tumor burden
• Better prognosis
• Normal kidney function

Stage II

• Intermediate disease
• Moderate cancer burden
• Requires active treatment

Stage III

• Advanced disease
• Significant organ involvement
• High-risk genetic abnormalities
• More aggressive treatment needed

Early-stage diagnosis is associated with better outcomes.

How Multiple Myeloma Is Diagnosed

Doctors diagnose multiple myeloma using several tests after evaluating the signs of multiple myeloma, including persistent bone pain, fatigue, frequent infections, anemia, kidney problems, or abnormal blood test results. Early recognition of the signs of multiple myeloma allows doctors to perform the appropriate diagnostic tests and begin timely treatment. A combination of laboratory tests, imaging studies, and a bone marrow biopsy helps confirm the diagnosis, determine the stage of the disease, and guide the most appropriate treatment plan.

Blood Tests

• Complete Blood Count (CBC)
• Serum Protein Electrophoresis (SPEP)
• Immunofixation
• Serum Free Light Chain Test
• Calcium
• Creatinine

Urine Tests

Doctors check for abnormal proteins called Bence Jones proteins.

Bone Marrow Biopsy

A sample of bone marrow confirms the presence of abnormal plasma cells.

Imaging Tests

Imaging helps detect bone damage.

Tests may include:

• MRI
• PET Scan
• CT Scan
• X-rays

How Do Doctors Diagnose Multiple Myeloma?

Diagnosing multiple myeloma involves a combination of physical examination, medical history, laboratory tests, imaging studies, and a bone marrow biopsy. Since the symptoms can resemble those of other conditions, doctors use several tests to confirm the diagnosis and determine the stage of the disease.

Medical History and Physical Examination

The diagnostic process usually begins with a discussion of your symptoms, medical history, and family history. Your doctor may also perform a physical examination to check for bone tenderness, signs of anemia, kidney problems, or other complications.

Blood Tests

Blood tests help identify abnormal proteins and evaluate how multiple myeloma is affecting the body. Common blood tests include:

• Complete Blood Count (CBC) to check for anemia.
• Serum Protein Electrophoresis (SPEP) to detect abnormal M proteins.
• Serum Free Light Chain (FLC) Assay to measure abnormal antibody fragments.
• Blood calcium levels to detect hypercalcemia.
• Kidney function tests (creatinine and BUN).
• Beta-2 Microglobulin and Albumin levels, which help determine the stage and prognosis.

Urine Tests

Urine tests look for abnormal proteins known as Bence Jones proteins, which may indicate kidney involvement. A 24-hour urine collection may also be recommended to measure protein levels.

Bone Marrow Biopsy

A bone marrow biopsy is the most important test for confirming multiple myeloma. During this procedure, a small sample of bone marrow is collected—usually from the hip bone—and examined under a microscope to identify abnormal plasma cells.

Imaging Tests

Imaging scans help detect bone damage and assess the extent of the disease. Your doctor may recommend:

• X-rays (Skeletal Survey)
• Low-Dose Whole-Body CT Scan
• MRI (Magnetic Resonance Imaging)
• PET-CT Scan

These imaging tests can reveal bone lesions, fractures, or areas where myeloma has spread.

Genetic and Cytogenetic Testing

Doctors may perform specialized genetic tests such as FISH (Fluorescence In Situ Hybridization) or cytogenetic analysis on bone marrow samples. These tests identify high-risk genetic abnormalities and help determine the most appropriate treatment plan.

Diagnostic Criteria for Multiple Myeloma

A diagnosis of multiple myeloma is typically confirmed when abnormal plasma cells are found in the bone marrow along with evidence of organ damage or specific biomarkers associated with the disease. Your healthcare team combines the results of blood tests, urine tests, imaging studies, and biopsy findings to make an accurate diagnosis and develop a personalized treatment plan.

Multiple Myeloma Treatment

The goal of multiple myeloma treatment is to control the disease, relieve symptoms, and improve quality of life.

Treatment depends on:

• Stage
