Have you ever been a little scared when you found a small lump or tumor on your body, especially on a bone in your arm or leg? Or have you ever felt a great burden on your heart when you saw something like that on your child's body? It's very normal to have the fear of "Is this cancer?" But I'm happy to tell you, not all tumors that form in the bones are cancer . In fact, most of the time, these are non-cancerous , harmless tumors. So today, let's talk about these non-cancerous bone tumors , that is, `(Benign Bone Tumors)`.
Simply put, what are these non-cancerous bone tumors?
As the name suggests, the most important thing is that it is “non-cancerous.” These are cells that start in a bone. But they are not as aggressive as cancer cells . The main characteristic of cancer is that it spreads from where it started to other parts of the body (like the lungs , liver ). But these `(Benign)` tumors do not spread like that. That is, they stay in the same bone where they started. They are like a normal birthmark on the skin. They are there, they may get a little bigger, but they do not spread anywhere else.
This type of tumor can develop in any bone in our body, but it is most common in the largest bones in our body. For example:
Some types of tumors have specific locations where they can form. For example, they can form in areas where bones grow (growth plates) around joints such as the hip, knee, or shoulder.
How common are these tumors? Who gets them the most?
This is an important fact that you need to know. These non-cancerous bone tumors are most common in people under the age of 30. They are especially common in infants and young children whose bones are still developing.
Think about it, there is an age when our bones stop growing. We call it `(Skeletal Maturity)` in medical terms. Simply put, “the time when bone growth is complete”. Most often, girls stop growing when they are 14-16 years old, and boys between the ages of 16-19. The amazing thing is that many `(Benign)` tumors, as soon as these bone growth stops, the tumors also stop growing . Some of them can even shrink on their own.
That means, if the doctor tells you that your child has a lump like this, don't worry unnecessarily. In most cases, it's a problem that will resolve itself as the child grows older.
What are the most common types of non-cancerous bone tumors?
There are different types of these nuts. Don't worry if the names sound a bit scientific. I'll explain it simply. It will be much easier for you to look at this information in a table.
| Tumor Type | Simple explanation |
|---|---|
| Enchondroma | These are made up of cartilage. They are located inside the bone, in the space where the bone marrow is. |
| Osteochondroma | These are made up of both cartilage and bone. They can also grow larger as the bone grows. They grow out of the bone. |
| Non-ossifying fibroma | This is the most common type seen in children. Most of the time, these go away on their own. They are discovered accidentally when an X-ray is taken for another accident. |
| Chondroblastoma | These are usually removed surgically because they affect nearby joints. These can cause severe pain in children. |
| Osteoid osteoma | These tend to develop in the long bones of the limbs and are more common in boys. The main symptom is severe pain, especially at night . Painkillers (NSAIDs) can help reduce the pain. |
| Giant cell tumor | These are a little rare. But they can grow quickly. Women are a little more likely to develop them. Most of the time, surgery is needed. |
| Aneurysmal bone cyst (Aneurysmal bone cyst – ABC) | These can grow very large and may require surgery or sclerotherapy to shrink the tumor. |
| Unicameral bone cyst (UBC) | These also form near the growth plates. This tumor can weaken the bone and cause it to fracture . This is when it is most often found. |
Why do tumors like this form?
In fact, most of the time, there's no clear cause for this. It's thought that a tumor forms when cells in our bones start to divide and grow uncontrollably for some reason. But researchers are still trying to figure out why.
What are the symptoms of this tumor?
The surprising thing here is that most ``benign`` bone tumors do not show any symptoms .
Imagine, your child falls while playing and hurts his arm. So you take your child to a doctor and get an X-ray. That's when the doctor sees that there's a small bone in the arm. Until then, neither you nor your child know about it. Most of the time, these things are discovered by accident like this.
However, sometimes symptoms may appear. In such cases, you may see the following:
- A visible swelling or lump: The area where the tumor is located may appear swollen and visible above the skin.
- Pain: Sometimes there may be severe pain. This pain may increase day by day. Sometimes the pain may be felt even when you are not doing anything and are at rest.
- Fractures: As the tumor grows, it weakens the bone. This makes it more likely that a bone will break even with a minor fall that would not normally break it.
How does a doctor find this?
If you suspect you have a lump or swelling on a bone, the first thing to do is see your doctor immediately . The doctor will first examine you carefully. Then, they may order several tests to confirm the diagnosis:
- Imaging Tests:
- X-ray: This is the first, simplest, and most important test. An X-ray can often give a good idea of the nature of the tumor.
- CT scan (Computed Tomography scan): Can produce more detailed three-dimensional images than X-rays.
- MRI scan (Magnetic Resonance Imaging scan): This helps to get a clear picture of the soft tissues (muscles, nerves) surrounding the bone.
- Bone Scan: This test is performed to find areas of increased cell activity in the bones of the body.
Most of the time, blood or urine tests are not needed to detect a benign tumor like this. An X-ray is done first, and only if necessary, other scans are performed.
What are the treatments for this?
There is no single treatment for every ``benign`` bone tumor. Treatment depends on the type of tumor you have, its size, where it is located, and how much it has affected your bone.
1. Observation: In most cases, the best decision a doctor can make is to “wait and see.” Especially for asymptomatic, incidentally discovered, small tumors, they will not be treated and will be monitored with regular X-rays to see if the tumor is getting bigger.
2. Surgical Removal: If the tumor is causing pain, is growing rapidly, or is at risk of breaking the bone, the doctor may decide to perform surgery.
- The surgery involves removing the tumor completely.
- Bone grafting is sometimes performed to fill the void left by the tumor removal. This means that a small piece of bone or artificial material taken from another part of the body is used to fill the void.
- The specialists who perform these surgeries take great care to remove only the tumor while minimizing damage to the surrounding healthy tissue. That's why the results are very successful.
3. Other treatment methods:
- For some tumors, such as osteoid osteoma, a treatment called radiofrequency ablation can be performed without surgery, using a needle-like device inserted through the skin and destroying the tumor with radio waves.
- Tumors such as ``Aneurysmal bone cysts (ABCs)'' can be treated without surgery by injecting the tumor with a medicine that causes it to shrink several times.
Are there any risks in surgery?
These are usually simple surgeries, and major complications are rare. However, as with any surgery, there are some risks that can occur very rarely.
- Nerve damage
- Infections
- Bleeding
- Stiffness of joints
But the chances of these happening are very low, so don't be unnecessarily afraid of them.
What is the outlook for this condition? (Prognosis)
This is the best news you will ever hear. The outlook for someone with non-cancerous bone tumors is excellent .
There are effective treatments for these. After treatment, the pain disappears completely. This condition is almost never life-threatening. Also, the chance that this is a ``Benign'' tumor that will later turn into cancer is very low (much less than 1%).
Therefore, there is no reason to be unnecessarily afraid or depressed about this.
Take-Home Message
- Don't be afraid to think it's cancer when you see a lump in your bone. The majority of lumps that form in bones are non-cancerous (benign) and harmless.
- This condition is very common, especially among children and young people .
- Most of the time, these tumors have no symptoms and are discovered accidentally when an X-ray is taken for another reason.
- If you have a swelling, lump, or pain that increases day by day and doesn't go away even with rest, see a doctor without delay .
- There are effective treatments for this condition. The results and outlook after treatment are very good .
