Have you ever thought that our bones, that is, bones, can also develop cancer? Perhaps you or someone you know has experienced bone pain or a small lump and wondered about it. What exactly is bone cancer, how does it develop, what are the symptoms, and is there a treatment? We will talk about all of this today, very simply.
What is Bone Cancer?
Simply put, "Bone Cancer" is a general term for several different types of cancer that develop in our bones. When these cancer cells start to grow inside a bone, like a bad plant, they damage our good bone tissue. That means they damage healthy bones. Although these cancers can develop in any bone, they are most commonly seen in the thigh bone, shin bone, or upper arm bone.
Now, there are two main types of bone cancer. One is when a cancer starts in the bones . We call them 'primary bone cancers' or 'bone sarcomas'. The other type is when a cancer starts somewhere else in the body, like the breast, lung, or prostate, and it spreads to the bones . We call this 'bony metastases'. It's like when a cancer starts somewhere else and then spreads to the bones. Breast cancer, prostate cancer, and lung cancer are the types that are most likely to spread to the bones.
Bone cancer is actually a serious condition, so it's important to treat it quickly . But there's good news! Our doctors have a variety of ways to treat these bone cancers, and sometimes they can even be cured completely.
What types of bone cancer are there?
There are three main types of primary bone cancer, which is cancer that begins in the bone itself. These are classified based on the type of cell and tissue in which the cancer begins:
1. Osteosarcoma : This is the most common type of bone cancer. It begins in the cells that form new bone tissue. It is most common in young children (especially between the ages of 10 and 20) , but can also occur in children and young adults.
2. Ewing sarcoma : This type of cancer can develop in the bones as well as the surrounding soft tissues. It is also most common in children and young adults .
3. Chondrosarcoma : This cancer starts in cartilage, the soft connective tissue that helps our joints and bones move. It is most common in adults .
In addition to these three main types, there are other rare types of bone cancer:
- Chordoma : This cancer develops in the spinal cord or at the base of the skull.
- Fibrosarcoma : These begin in the fibrous connective tissue at the ends of bones.
- Giant cell tumors : These are actually non-cancerous (benign) tumors. However, they can very rarely become cancerous.
- Undifferentiated pleomorphic sarcoma : These are a less aggressive type of cancer that starts in soft tissues and bones.
How common is bone cancer?
But here's the thing, bone cancer is not very common . In fact, compared to other types of cancer, it is very rare. For example, in a country like America, bone cancer accounts for less than 1% of all cancers. Although it can develop in anyone of any age, it is more common in children and young people than in adults.
The important thing is that just because you have a lump in your bone, it doesn't necessarily mean it's cancer. Most bone tumors are noncancerous (benign). These noncancerous tumors don't spread throughout the body like cancer does.
What are the symptoms of bone cancer?
Some people with bone cancer may not show any symptoms, just a painless lump. But others may have a variety of symptoms. Imagine your child or someone you know constantly complaining of pain in one leg or arm, worse at night, or sometimes a sharp, stabbing pain . You may think, "Oh, this must have been from a fall while playing," or "It's just growing pains." Sometimes these symptoms can be mistaken for other conditions, such as arthritis. This can delay the diagnosis.
These are the most common symptoms of bone cancer:
- Bone pain that gradually increases and is persistent (usually worse at night. It may be dull, aching, or stabbing).
- A lump or swelling in the affected area (which may feel hard or soft to the touch).
- Unexplained swelling around the affected bone.
- Difficulty moving (especially if the swelling is near a joint).
- Fatigue .
- Fever .
What are the causes of bone cancer?
Experts still don't know exactly what causes bone cancer. But like other cancers, bone tumors develop when cells start to grow out of control due to errors in their DNA. Over time, these cells can grow together to form a mass, damaging surrounding healthy tissue. If left untreated, bone cancer can spread to other parts of the body.
Risk factors
Researchers have found a link between bone cancer and certain risk factors. These are:
- Having received previous cancer treatment : If you have received radiation therapy or certain chemotherapy drugs as treatment for other cancers, your risk of developing bone cancer in the future may be slightly increased.
- Genetic factors : Some rare, inherited genetic conditions, such as Li-Fraumeni syndrome, may increase the risk of bone cancer. Also, inheriting a genetic mutation that causes a condition called retinoblastoma also increases the risk.
- Non-cancerous bone diseases : Very rarely, non-cancerous bone conditions can turn into cancer. For example, if you have conditions called `Paget disease of the bone` or `multiple enchondromas`, the risk may be slightly increased.
However, many people who develop bone cancer do not have any of these risk factors . Often, it occurs for no apparent reason.
What are the complications of this condition?
Bone cancer weakens the bones it grows into. Sometimes, this cancer can cause bone fractures. We call these 'pathologic fractures'. Sometimes doctors find bone cancer when they examine a bone fracture like this.
How is bone cancer diagnosed? (Diagnosis)
To diagnose bone cancer, your doctor will first take X-rays to look at your bones. Then, they will often do Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans to get clearer images of the areas around the bones. These are essential before starting treatment.
To confirm the diagnosis, your doctor will do a biopsy . This means taking a small piece of tissue from your bone and having it examined under a microscope by a specialist (pathologist). The biopsy provides specific information about the type of cancer. With this information, your doctor can decide exactly what treatment is best for you.
Bone Cancer Staging
By determining the stage of the cancer (`Cancer staging`), doctors can determine whether the cancer is localized or has spread throughout the body (metastasized). They also look at how likely it is to spread, if it hasn't spread yet. How abnormal the cancer cells look (`tumor grade`) gives an indication of how likely the cancer is to spread. There are two methods doctors use to determine the stage of bone cancer:
1. Musculoskeletal Tumor Society (`Musculoskeletal Tumor Society`) or `Enneking system`:
- Stage 1 : The cancer is low-grade and has not spread.
- Stage 2 : The cancer is high-grade, but has not spread.
- Stage 3 : The cancer has spread.
2. American Joint Committee on Cancer (`American Joint Committee on Cancer - AJCC`) system:
- Stage 1 : The tumor is low-grade and the cancer has not spread.
- Stage 2 : The cancer has not spread, but the tumor is high-grade.
- Stage 3 : The tumor is high-grade, and the cancer has spread to other areas within the same bone.
- Stage 4 : The cancer has spread from the bone to other parts of the body, for example, the lungs or liver.
How is bone cancer treated?
The main treatment for bone cancer is surgery to remove the cancer . The most common type of surgery is ``Limb-sparing surgery.'' In this surgery, the surgeon removes only the cancer and a small amount of healthy tissue around it, but leaves your arm or leg intact. The damaged bone can be rebuilt with either ``real bone grafts'' or ``artificial bone grafts.''
Sometimes, the surgeon may have to remove an entire arm or leg (`amputation`) to treat cancer. If that happens, you will be fitted with a prosthetic arm or leg after the surgery. These devices are now very advanced, and they can help you carry out your daily activities just as they did before the surgery.
Other treatments are:
- Radiation therapy : This is used to shrink tumors before surgery or to destroy any remaining cancer cells after surgery. Radiation therapy can also be used instead of surgery for some bone cancers.
- Chemotherapy : This is given to treat the primary cancer, the cancer that has spread (metastases), and the cancer cells that are floating around in the body. Chemotherapy is usually given before surgery to control the spread of the cancer and possibly shrink the tumor. Chemotherapy (chemo) given after surgery helps to "clean up" any remaining cancer cells in the body and prevent the bone cancer from coming back.
How quickly will I feel better after treatment?
Pain caused by bone cancer usually begins to subside as soon as treatment begins. However, treatment can also cause some side effects, and recovery takes time.
It can take up to six months of rehabilitation and physical therapy to get used to a prosthesis. If you had limb-sparing surgery, it can take up to a year to feel completely comfortable with the changes to your bones.
Ultimately, your recovery time depends on the type of cancer, its stage, and the combination of treatments you need. Your doctor will tell you what to expect, so you can decide which treatments are best for you.
Can bone cancer be prevented?
Since experts still don't know exactly what causes bone cancer, there's currently no way to prevent it . On the other hand, radiation therapy, which is another known cause of bone cancer, is essential for treating some other cancers, so it can't be avoided entirely.
However, you should see a doctor if you notice any unusual changes in your bones, such as a lump or increasing bone pain. These symptoms do not always mean cancer. However, only a doctor can diagnose the exact cause of the problem.
What can I expect if I have bone cancer?
Treatment for bone cancer is often successful . In most cases, the cancer does not come back. It may take more than one surgery to achieve this result.
People with more advanced types of bone cancer may need to continue treatments, such as radiation therapy and chemotherapy, to prevent the cancer from spreading. These treatments may be given for a long time to control the cancer.
Finally, everyone's situation is different, so not everyone with bone cancer will have the same outcome. Your doctor will explain your prognosis based on the type, stage, location of your cancer, and your response to treatment.
What is the cure rate for bone cancer?
Although bone cancer can be fatal, many people make a full recovery . The five-year relative survival rate for bone cancer is 68.2%. This means that 68.2% of people with bone cancer are still alive five years after diagnosis. People with early-stage bone cancer have a better chance of making a full recovery. People with advanced-stage bone cancer, meaning that the cancer has already spread, are at higher risk of the cancer coming back.
But remember, these survival rates are just estimates based on people who have had bone cancer in the past. They don't tell you exactly how long you will live or what to expect in your specific situation. Talk to your doctor for more information about bone cancer survival rates.
When should I see a doctor?
If you have unexplained bone pain or swelling , make an appointment to see a doctor right away . If your child has a lump or swelling that doesn't go away, see your child's doctor. If you're already being treated for bone cancer, let your doctor know if you develop any new symptoms.
After treatment, be sure to attend all follow-up appointments . During the first two years, you may need to see your doctor every three to six months, and then check-ups will be less frequent. By having regular check-ups like this, you can catch the cancer early if it comes back, and your treatment will be more effective.
What questions should I ask my doctor?
Understanding your diagnosis fully will help you make the best decisions about your health. Here are some questions you can ask your doctor:
- What type of bone cancer do I have?
- Has it spread?
- What tests do I need to do?
- What are my treatment options?
- What is my prognosis?
When you find out you have bone cancer, you may feel scared, frustrated, and uncertain. Of course, there are many unknowns associated with a cancer diagnosis. Your experience will depend on many factors, including the type of bone cancer you have and when you are diagnosed. But bone cancer is not always fatal or incurable. Many people who are diagnosed with this disease receive treatment that eliminates the cancer .
Talk to your doctor about your treatment options. Also, consider joining a support group. Talking to people who are going through the same things as you can be good for your mental, emotional, and spiritual health.
Take-Home Message
Bone cancer is something to be really afraid of, but the most important thing is to be well-informed about it and seek medical advice at the right time .
Remember, not all bone pain or lumps are cancer. However, if you have any concerns, it's wise to talk to a doctor about it.
With the advancement of modern medicine, there are many effective treatments for bone cancer. In some cases, it can even be completely cured. Therefore, it is very important to stay strong and follow the advice of your doctors. You are not alone, and you have family, friends, and doctors to help you on this journey.
