Do you often talk about your child's joint pain? Or if you are a little younger, do you also have something like this in your joints, maybe a little swelling? Sometimes behind these symptoms there can be a very rare condition, but it is very important for us all to be aware of. That is why today we are going to talk about a type of bone tumor called `Chondroblastoma`, which is not cancerous . Don't worry, let's talk about this simply.
What is this `Chondroblastoma`? Simply put...
Okay, Chondroblastoma is a very rare, non- cancerous bone tumor. It is made up of cartilage tissue. Cartilage is the rubbery part of our joints that helps them move smoothly. This tumor forms when cells in our body grow faster than they should, or when cells that should die don't die. In medicine, we also call this a neoplasm.
Chondroblastoma tumors most commonly develop in our long bones, that is, in the long bones of our legs and arms, near the joints, where the bones grow (the `growth plate`). Do you remember when we were kids, when we grew taller, our bones grew because of those `growth plates`? These tumors are most commonly seen in the thigh bone (`femur`), the upper arm bone (`humerus`), and the shin bone (`tibia`).
Who gets this `Chondroblastoma`? How common is it?
This may sound a little scary, but Chondroblastoma is actually a very rare condition. It accounts for less than 1% of all bone tumors.
The condition mostly affects children and young adults. 25% of diagnosed cases are children under 10 years of age. However, the majority, about 75%, are adolescents and young adults between the ages of 11 and 25. It is also said that men are slightly more likely to develop the condition than women.
Is Chondroblastoma a cancer?
This is the biggest problem that many people have. No! Chondroblastoma is not cancer. That means it is a benign tumor. "Benign" means that it is not a serious cancer that can spread to other parts of the body and cause life-threatening problems. Removing this tumor through surgery can eliminate the pain and possible damage to the bone. So there is no reason to be unnecessarily afraid.
What is the difference between `Chondroblastoma` and `Enchondroma`?
Both are non-cancerous bone tumors. However, the main difference between Chondroblastoma and Enchondroma is where they are located.
- Chondroblastoma, as we discussed earlier, occurs near the joints of long bones.
- Enchondroma is a type of tumor that develops in the cartilage inside the bone. These tumors are most commonly found in the fingers and toes. Enchondroma often does not cause pain. They are often discovered incidentally when an X-ray is done for another reason.
What are the symptoms of Chondroblastoma?
The symptoms of `Chondroblastoma` do not appear suddenly. They appear gradually , and may increase over time. The main symptoms that can be seen are:
- Joint pain: This is the main symptom. For some, it may be a mild ache, while for others, it may be a sharp pain accompanied by unbearable burning.
- Tenderness when touching the long bone: You may feel pain when you place your hand over the bone where the tumor is located.
- Swelling due to fluid accumulation around the joint (joint effusion): The joint may feel swollen and possibly watery.
- Muscle atrophy: For example, if you have a tumor like this on your leg, you may notice a limp on that side. This is a gradual loss of muscle mass. For example, your child may not be running and playing as much as they used to, may be complaining that their leg is sore, or may have a swollen joint... If this continues, it is best to seek medical advice.
What causes Chondroblastoma?
In fact, the exact cause of Chondroblastoma has not yet been found . However, according to medical research, it is believed that these tumors may arise from the cartilage cells in the growth plates that we talked about earlier, which are located at the ends of the bones. These are like the factories where our bones "grow". It is thought that this condition occurs due to some abnormality in cell division there.
Can Chondroblastoma spread to other parts of the body?
This is also an important issue. Chondroblastoma usually does not spread. However, very rarely , some aggressive Chondroblastoma tumors can spread (metastasize) to the lungs. But the important thing to remember here is that even if it spreads to the lungs, Chondroblastoma is still not considered cancer . That is, it is still a benign condition. This is a bit complicated, but doctors manage this condition well.
How is Chondroblastoma diagnosed?
There are several key steps to diagnosing Chondroblastoma.
1. Medical examination and questioning: First, when you see a doctor, he or she will examine you and ask you questions about your pain. For example:
- How long has this pain been there?
- Where exactly is the pain?
- Does the pain decrease with rest?
- Did the pain increase over time?
Questions like these can help the doctor get a basic idea of your condition.
2. Imaging Tests: Next, the doctor will often order one or more of the following tests:
- X-ray: This can give a rough idea of the changes in the bones, the location, and the size of the tumor.
- MRI scan: This can provide a clearer picture of the soft tissues, cartilage, and nature of the tumor surrounding the tumor.
- CT scan: This can also provide detailed information about the bones and the tumor.
3. Biopsy: To confirm the diagnosis 100%, the doctor will order a biopsy. This involves putting you under anesthesia and a surgeon removing a very small sample of tissue from the tumor and sending it to the lab. Only by examining the tissue under a microscope can we determine whether it is Chondroblastoma or something else.
How is Chondroblastoma treated?
Once the diagnosis is confirmed, the doctor will plan surgery to remove the tumor. Surgery is the main and most commonly used treatment for chondroblastoma. This is essential because only by removing the tumor can the pain be relieved and further damage to the bone be stopped.
Sometimes, the tumor may have damaged the bone. If this is the case, the surgeon may perform a ``bone grafting`` after removing the tumor. Simply put, this involves taking a piece of healthy bone from another part of your body (such as your hip bone) and "gluing" it to the damaged area. Or, sometimes, specially prepared bone substitutes can be used.
Very rarely, depending on the location and size of the tumor, surgery may not be able to safely remove the tumor completely. In such cases, your doctor may recommend other non-surgical treatments. For example:
- Radiofrequency ablation: This uses high-frequency electrical waves to heat and destroy the tumor.
- Cryotherapy: This involves using something extremely cold, such as liquid nitrogen, to freeze the tumor and destroy it.
What medications can be used for pain?
The main symptom of `Chondroblastoma` is joint pain. In the early stages, you can control the pain with painkillers such as `Paracetamol`, which you can buy from the pharmacy. However, as the tumor grows, these common painkillers become unable to control the pain. Surgical removal of the tumor is the best solution to completely eliminate the pain.
Do I really need surgery?
Yes, surgery is most likely necessary. Surgery is the best way to remove the tumor and relieve the pain. If the tumor is left untreated, it can continue to grow. If that happens, it can damage the bone, cause severe pain, and make it impossible to move the joint where the tumor is located.
How is the recovery time after surgery?
The recovery time and rehabilitation process after surgery can vary depending on the size and location of the tumor, and the damage to the bone.
Usually, you will stay in the hospital for about a day after surgery, under the supervision of doctors. You may feel some pain and discomfort for the first two to three weeks after surgery until the wound heals. However, there are no symptoms of `Chondroblastoma`. For mild to moderate pain after surgery, the doctor may recommend `NSAIDs` (Nonsteroidal anti-inflammatory drugs), such as `Ibuprofen`. These reduce pain and swelling.
Important: If you experience the same pain after surgery, it could be a sign that the tumor has returned. Therefore, it is important to have regular check-ups as prescribed by your doctor to ensure that your surgery is healing properly.
What exercises can be done after surgery?
A big part of the recovery process after surgery is gradually rebuilding joint function and strengthening muscles. Only then can you return to the things and activities you enjoy. This is how exercise usually begins:
- One week after surgery: You can begin light exercises (e.g., flexing and extending the joint) without applying any weight, just as you would after surgery.
- Six weeks after surgery: You can do light, weight-bearing exercises.
- Three months after surgery: You can do full, weight-bearing exercises, but you should avoid strenuous activities.
- Six months after surgery: You will likely be fully recovered and able to return to normal life.
You should discuss all of this with your doctor and physiotherapist and follow their advice.
Can my Chondroblastoma tumor come back after surgery?
There is a small chance of the tumor coming back within the first few months or years after surgery, about 10% . That is why after surgery, the doctor will regularly monitor the affected area with X-rays and regular checkups. If the tumor comes back, another surgery may be necessary.
How to reduce the risk of developing `Chondroblastoma`?
Since the exact cause of chondroblastoma is unknown, there is no specific way to reduce the risk of developing it. But the good news is that once the tumor is treated and removed, the symptoms usually go away.
If I have Chondroblastoma, what should I expect?
After diagnosis and treatment, your outlook depends on the location and size of the tumor. Usually, surgery will relieve your pain and discomfort . There is about a 10% chance that the tumor will come back. If the chondroblastoma has damaged the cartilage in your joint, there is a small chance that arthritis, a condition in which the joint becomes inflamed, will develop over time.
Is there a mortality rate for Chondroblastoma?
No. Chondroblastoma is a non-cancerous tumor that can be cured with surgery, so there is no direct risk of death from this tumor . This is a matter of great comfort to many people.
When should I see a doctor?
If you have any of these symptoms, see a doctor immediately:
- If you have severe pain or persistent, unrelenting pain in your joints.
- If the joint pain recurs after the tumor is removed.
- If there is pain, redness, swelling and/or pus draining from the surgical site (these may be signs of infection).
What questions should I ask my doctor?
When you go to see the doctor, asking questions like these can help you get a better understanding of the situation:
- How big is my Chondroblastoma tumor?
- Can my tumor be safely removed surgically?
- How can I prevent infection at the surgical site?
- How long will it take to recover? When can I resume normal activities?
