Bone cancer is a rare type of cancer that begins in the bones, affecting their structure, strength and function. Although primary bone cancer is uncommon, recognising the symptoms early is important, as prompt diagnosis and treatment can significantly improve outcomes. It's also important to understand that secondary bone cancer (bone metastases), where cancer spreads to the bones from another part of the body, is much more common than primary bone cancer.
Many people experience bone pain during their lifetime due to injuries, arthritis or overuse. However, persistent bone pain that gradually worsens, particularly at night or while resting, should never be ignored. Other symptoms, such as swelling, unexplained fractures or reduced mobility, may also require medical assessment.
At Private Medical Clinic, we believe in providing clear, evidence-based information to help patients understand their symptoms and make informed decisions about their health. In this guide, we'll explain bone cancer symptoms, warning signs, possible causes, diagnosis, treatment options, prognosis and when to seek medical advice.
Bone cancer develops when abnormal cells within the bone begin to grow uncontrollably, forming a tumour. As the tumour grows, it can weaken the affected bone, increasing the risk of persistent pain, fractures and reduced mobility. In some cases, cancer cells may spread (metastasise) to other parts of the body, most commonly the lungs.
There are two main types of bone cancer:
Primary bone cancer can occur at any age but is more frequently diagnosed in teenagers and young adults, while certain types are more commonly seen in older adults.
Understanding the difference between primary and secondary bone cancer is important because diagnosis, treatment and prognosis vary depending on the type of cancer.
Although bone cancer is rare, there are several different types. The treatment approach and outlook depend on the specific type diagnosed.
Osteosarcoma
Osteosarcoma is the most common type of primary bone cancer. It usually develops in the long bones of the arms or legs, particularly around the knee, and most commonly affects teenagers and young adults during periods of rapid growth.
Chondrosarcoma
Chondrosarcoma develops in cartilage, the connective tissue found around joints. It is more common in adults over the age of 40 and often affects the pelvis, shoulder or upper leg.
Ewing Sarcoma
Ewing sarcoma is a rare cancer that typically affects children, teenagers and young adults. It often develops in the pelvis, ribs or long bones and may spread more quickly than some other bone cancers if left untreated.
Chordoma
Chordoma is a rare, slow-growing cancer that develops in the bones of the spine or base of the skull. Although uncommon, it can cause symptoms by pressing on nearby nerves and tissues.
Bone cancer symptoms can vary depending on the type of cancer, its size and where it develops in the body. In the early stages, symptoms may be mild and easily mistaken for a sports injury, arthritis or another musculoskeletal condition. As the tumour grows, symptoms often become more persistent and noticeable.
Common bone cancer symptoms include:
While these symptoms do not necessarily mean you have bone cancer, persistent or unexplained symptoms should always be assessed by a healthcare professional.
One of the most common questions people ask is, "What are the 7 warning signs of bone cancer?" Although symptoms vary from person to person, the following warning signs are widely recognised and should not be ignored.
1. Persistent Bone Pain
Persistent pain is often the earliest and most common symptom of bone cancer. Unlike pain caused by exercise or injury, it usually becomes progressively worse over time and may continue even when resting.
2. Pain That Worsens at Night
Many people report that bone cancer pain becomes more noticeable during the night. Pain that regularly interrupts your sleep or continues despite pain relief should be assessed.
3. Swelling or a Lump
As a tumour grows, swelling or a firm lump may develop over the affected bone. In some cases, the swelling may only become noticeable after the pain has been present for several weeks or months.
4. Bones That Fracture Easily
Bone cancer can weaken the affected bone, increasing the risk of fractures after minor injuries or everyday activities that would not normally cause a bone to break.
5. Reduced Mobility or Joint Stiffness
If the cancer develops near a joint, it may cause stiffness, reduced flexibility or difficulty moving the affected limb. Some people may also develop a limp if the legs, hips or pelvis are involved.
6. Unexplained Weight Loss and Fatigue
Like many cancers, bone cancer may cause unintended weight loss, ongoing fatigue and a general feeling of being unwell, particularly as the disease progresses.
7. Fever or Night Sweats
Although less common, some people experience persistent low-grade fevers or night sweats alongside other symptoms. These signs should always be considered in the context of persistent bone pain or swelling.
If you experience one or more of these warning signs—particularly if symptoms continue for several weeks or worsen over time—it's important to arrange a medical assessment. Early diagnosis can improve treatment options and overall outcomes.
One of the most common questions people ask is, "What does bone cancer feel like?" While every person's experience is different, bone cancer pain has several characteristics that distinguish it from the aches and pains caused by exercise, arthritis or minor injuries.
In the early stages, the pain may come and go, making it easy to dismiss. Over time, however, it typically becomes more persistent and gradually worsens.
Bone cancer pain may:
Unlike a muscle strain or sports injury, bone cancer pain often does not improve with rest and may continue even after the original cause appears to have resolved.
It's important to remember that persistent bone pain does not necessarily mean cancer. Many more common conditions, such as arthritis, tendon injuries and osteoporosis, can also cause ongoing pain. However, persistent or unexplained symptoms should always be assessed by a healthcare professional.
Many people wonder, "How long can you have bone cancer without knowing?"
The answer varies depending on the type of bone cancer, where it develops and how quickly it grows.
Some bone cancers develop gradually, with mild symptoms that can easily be mistaken for sports injuries, arthritis or general wear and tear. As a result, some people may experience symptoms for several months before seeking medical advice.
Others develop more rapidly and cause significant pain, swelling or fractures within a shorter period.
Because early symptoms are often non-specific, diagnosis can sometimes be delayed. This is why persistent bone pain, particularly when it worsens over time or occurs at night, should never be ignored.
Seeking medical advice early allows appropriate investigations to be arranged and, if necessary, treatment to begin as soon as possible.
Many patient stories begin with what seemed like a relatively minor problem.
Some people first notice a persistent ache after playing sport, while others experience swelling around a joint or a pain that never completely disappears. Initially, these symptoms are often attributed to muscle strain, arthritis or overuse.
Over time, however, the pain may become more severe, begin waking someone during the night or continue despite rest and pain medication. In some cases, a fracture following a relatively minor injury prompts further investigation.
Stories of "How I found out I had bone cancer" often share one important lesson: persistent symptoms deserve further assessment.
If your symptoms are not improving, or they continue despite treatment, speak to your GP or healthcare professional. Further investigations, such as an X-ray or MRI scan, may help identify the underlying cause.
At Private Medical Clinic, we offer access to private GP appointments, diagnostic imaging and specialist referrals to help patients receive timely assessment where appropriate.
In most cases, the exact cause of primary bone cancer is unknown. However, researchers have identified several factors that may increase the risk of developing the disease.
Potential risk factors include:
Having one or more risk factors does not mean you will develop bone cancer, and many people diagnosed with the condition have no identifiable risk factors at all.
Importantly, there is currently no evidence that everyday activities, exercise or minor injuries cause bone cancer. However, an injury may draw attention to an area that already contains a tumour, leading to further investigation.
If your doctor suspects bone cancer, they will usually begin by discussing your symptoms, medical history and any potential risk factors before performing a physical examination.
Medical History and Physical Examination
Your doctor may ask about:
They will also examine the affected area for swelling, tenderness or reduced movement.
Imaging Tests
Imaging plays a key role in diagnosing bone cancer.
X-ray
An X-ray is often the first investigation performed. It can identify abnormal bone changes, weakened areas or suspicious growths that require further assessment.
MRI Scan
MRI scans provide highly detailed images of bones and surrounding soft tissues, helping doctors determine the size of the tumour and whether nearby structures are affected.
CT Scan
CT scans may be used to assess the tumour in greater detail or check whether cancer has spread to other areas, particularly the lungs.
PET-CT Scan
In some cases, a PET-CT scan may be recommended to evaluate whether cancer has spread elsewhere in the body and to assist with staging.
A common question is whether a bone profile blood test can detect cancer.
The short answer is no.
A bone profile blood test measures substances such as calcium, phosphate and alkaline phosphatase to assess bone health and identify certain abnormalities. While these results may suggest that further investigation is needed, they cannot diagnose or rule out bone cancer.
Other blood tests may also be performed to assess your general health before treatment, but imaging tests and a biopsy remain essential for confirming a diagnosis.
If imaging suggests a possible bone tumour, a biopsy is usually required to confirm the diagnosis.
During a biopsy, a specialist removes a small sample of tissue from the affected bone. This sample is examined under a microscope to determine whether cancer cells are present and, if so, the specific type of bone cancer.
A biopsy is considered the gold standard for diagnosing bone cancer and helps guide the most appropriate treatment plan.
Treatment depends on the type of bone cancer, its location, its stage and your overall health. Your care is usually managed by a multidisciplinary team of specialists, including orthopaedic surgeons, oncologists, radiologists and specialist nurses.
Treatment options may include:
Surgery
Surgery is often the main treatment for primary bone cancer. Whenever possible, surgeons aim to remove the tumour while preserving the affected limb using limb-sparing surgery. In rare cases where this is not possible, amputation may be necessary.
Chemotherapy
Chemotherapy uses anti-cancer medicines to destroy cancer cells. It is commonly used before surgery to shrink the tumour or after surgery to reduce the risk of recurrence.
Radiotherapy
Radiotherapy uses high-energy radiation to destroy cancer cells. It may be recommended for cancers that cannot be completely removed surgically or to help relieve symptoms.
Targeted Therapy
Some patients may be suitable for targeted therapies that focus on specific molecules involved in cancer growth. These treatments are used for certain types of bone cancer and are determined on an individual basis.
Living with bone cancer involves more than treating the disease itself. Recovery often requires ongoing physical, emotional and practical support.
Many patients benefit from:
Support from family, friends and healthcare professionals plays an important role throughout treatment and recovery.
At Private Medical Clinic, we understand that cancer affects every aspect of a person's life. Where appropriate, we can help coordinate investigations, specialist referrals and ongoing support to ensure patients receive comprehensive care.
The outlook for bone cancer varies considerably depending on:
Many people understandably ask about the bone cancer survival rate or whether bone cancer can be cured.
Some types of primary bone cancer can be successfully treated, particularly when diagnosed early before the cancer has spread. Advances in surgery, chemotherapy and radiotherapy continue to improve outcomes for many patients.
While every case is different, early diagnosis remains one of the most important factors influencing prognosis.
You should arrange a medical assessment if you experience:
Although these symptoms are often caused by conditions other than cancer, it is always advisable to seek medical advice if symptoms persist or worsen.
Early investigation can provide reassurance where appropriate or ensure that treatment begins as soon as possible if a serious condition is identified.
Bone cancer is a rare condition, but recognising the symptoms early can make a significant difference to diagnosis, treatment and long-term outcomes. Persistent bone pain, particularly when it worsens over time or occurs at night, should never be ignored. Swelling, unexplained fractures, reduced mobility and ongoing fatigue may also require medical assessment.
While most cases of bone pain are caused by conditions other than cancer, understanding the warning signs allows you to seek appropriate medical advice without unnecessary delay. Modern imaging techniques, specialist investigations and advances in treatment have greatly improved the outlook for many people diagnosed with bone cancer.

What are the 7 warning signs of bone cancer?
The seven most commonly recognised warning signs include persistent bone pain, pain that worsens at night, swelling or a lump over the affected bone, unexplained fractures, reduced movement or joint stiffness, fatigue with unexplained weight loss, and persistent fever or night sweats. Although these symptoms can have many causes, they should be assessed by a healthcare professional if they persist.
What are the early warning signs of bone cancer?
The earliest symptom is often persistent bone pain that gradually becomes worse over time. Unlike pain from an injury, it may continue even when resting and can become more noticeable at night. Swelling, tenderness or reduced movement may also develop as the condition progresses.
What does bone cancer feel like?
Bone cancer often causes a deep, aching pain within the affected bone. Initially, the pain may come and go, but it typically becomes more constant over time. Many people report that the pain worsens at night, is not relieved by rest and gradually becomes more severe.
Is bone cancer painful?
Yes. Persistent bone pain is the most common symptom of bone cancer. However, not all bone pain is caused by cancer. Arthritis, injuries, osteoporosis and other conditions are much more common causes of ongoing bone pain.
How long can you have bone cancer without knowing?
The timeframe varies depending on the type of bone cancer and how quickly it grows. Some people experience mild symptoms for several months before seeking medical advice, while others develop symptoms more rapidly. Early assessment of persistent symptoms can help avoid delays in diagnosis.
Can bone cancer be cured?
Some types of primary bone cancer can be successfully treated, particularly when diagnosed at an early stage before the cancer has spread. The outlook depends on several factors, including the type of cancer, its stage and how well it responds to treatment.
What causes bone cancer?
In many cases, the exact cause is unknown. However, certain risk factors may increase the likelihood of developing bone cancer, including previous radiotherapy, Paget's disease of bone and some inherited genetic conditions. Most people diagnosed with bone cancer have no obvious risk factors.
Can a blood test detect bone cancer?
No. There is currently no blood test that can diagnose bone cancer. Blood tests may identify abnormalities or help assess your overall health, but imaging tests and a biopsy are required to confirm the diagnosis.
Can a bone profile blood test detect cancer?
No. A bone profile measures substances involved in bone metabolism, such as calcium and alkaline phosphatase. While abnormal results may prompt further investigations, they cannot confirm or exclude bone cancer.
Can an X-ray detect bone cancer?
An X-ray is often the first imaging test used when bone cancer is suspected. It can identify abnormal bone changes or suspicious areas, but additional imaging and a biopsy are usually needed to confirm the diagnosis.
Is an MRI better than an X-ray for bone cancer?
MRI scans provide much more detailed images of bones and surrounding soft tissues than X-rays. They help determine the size of the tumour and whether nearby muscles, nerves or joints are affected.
How is bone cancer diagnosed?
Bone cancer is usually diagnosed using a combination of medical history, physical examination, imaging tests such as X-rays, MRI or CT scans, blood tests and a biopsy. A biopsy is the only way to confirm the diagnosis.
Can bone cancer spread?
Yes. Some types of bone cancer can spread (metastasise) to other parts of the body, most commonly the lungs. Early diagnosis and treatment help reduce the risk of the cancer progressing.
What is the difference between primary and secondary bone cancer?
Primary bone cancer starts within the bone itself and is relatively rare. Secondary bone cancer occurs when cancer from another part of the body, such as the breast, prostate or lung, spreads to the bones. Secondary bone cancer is much more common.
What is the most effective treatment for bone cancer?
Treatment depends on the type and stage of the cancer. Surgery is often the main treatment for primary bone cancer and may be combined with chemotherapy, radiotherapy or targeted therapies to achieve the best possible outcome.
What is the survival rate for bone cancer?
The outlook depends on the type of bone cancer, its stage at diagnosis, whether it has spread and how well it responds to treatment. Early diagnosis is associated with better outcomes and more treatment options.
Can children develop bone cancer?
Yes. Certain types of bone cancer, such as osteosarcoma and Ewing sarcoma, are more commonly diagnosed in children, teenagers and young adults, although bone cancer remains rare overall.
Is bone cancer hereditary?
Most bone cancers are not inherited. However, some rare genetic syndromes, such as Li-Fraumeni syndrome, may increase the risk of developing certain types of bone cancer.
When should I see a doctor about bone pain?
You should seek medical advice if bone pain persists for several weeks, becomes worse over time, occurs at night, is associated with swelling or a lump, or is accompanied by unexplained weight loss or fatigue.
Can bone cancer be prevented?
There is no guaranteed way to prevent bone cancer. However, recognising symptoms early and seeking prompt medical assessment can improve the chances of early diagnosis and successful treatment.
