Have you ever noticed an unusual lump or swelling somewhere on your body and been worried? Sometimes these things may not be that dangerous. However, today we are going to talk about a type of tumor that is a little special and deserves special attention. These are called desmoid tumors. Let's take a look at what they are, why they form, how to recognize them, and how to treat them.
What are Desmoid Tumors? Let's find out simply!
Simply put, desmoid tumors are not cancer . But they are also called aggressive fibromatosis. That means that sometimes they can grow very quickly and aggressively. They form in the connective tissue in our body. Think of it like the glue that holds different parts of our body together.
Although these tumors can develop anywhere on the body, they are most commonly seen on the stomach, arms, legs, and sometimes the head and neck .
The most important thing is that these tumors do not spread from one place in the body to another (they do not metastasize) like cancer.
However, there is one problem. These tumors often grow slowly . However, some can grow very quickly and spread into nearby tissues (locally infiltrative). In that case, it is very difficult to remove them with surgery. Another thing is that they are more likely to come back (recur) even after treatment. But not everyone's situation is the same, and it is important to remember that.
Are there any types of these nuts?
Yes, desmoid tumors can be divided into several main types, depending on where they form:
- Abdominal wall desmoid tumors: These develop in the tissue wall (abdominal wall) that surrounds organs inside our abdomen (like the stomach).
- Intra-abdominal desmoid tumors: These develop in the tissue lining around the intestines (mesentery).
- Extra-abdominal desmoid tumors: These develop outside the abdomen and abdominal wall. They most often start in the shoulders, upper arms, chest wall, and upper legs. They can also develop in the head and neck.
What are the symptoms? How do we know if we have it?
Desmoid tumors don't always cause major symptoms. However, symptoms only appear when the tumor grows large enough to press on nearby nerves or organs. These may include:
- A lump or swelling: This is most often seen on the arms, legs, or stomach.
- Nausea and vomiting: These symptoms may occur if there is a tumor in the stomach.
- Pain or numbness: This may be felt when the tumor presses on nerves, organs, or blood vessels near the tumor.
- It's hard to move an arm or a leg.
Important: Not every lump that forms on the body is a desmoid tumor. However, if you have a lump that is larger than two inches (about 5 centimeters), continues to grow, or is painful , it is best to see a doctor for advice.
Why do these desmoid tumors form? What are the causes?
These tumors form when cells in the connective tissue undergo a mutation and begin to divide rapidly and uncontrollably. Over time, these excess cells accumulate and form a tumor.
Doctors still don't know exactly why these cells change in the first place. However, research has identified several gene mutations associated with desmoid tumors. This information could help develop treatments that target those mutations and control the growth of the tumors.
Who is more likely to develop these? (Risk Factors)
Some people are more likely to develop desmoid tumors. Let's take a look at who they are:
- Young age: This disease is most often diagnosed in people between the ages of 30 and 40.
- Being female: Women are more likely to develop these tumors, especially during pregnancy or shortly after giving birth. They often appear on the abdominal wall. Because estrogen levels increase during pregnancy, some experts believe there is a link between estrogen and desmoid tumors.
- Having a condition called Familial Adenomatous Polyposis (FAP): This is an inherited condition. Between 5% and 10% of people with FAP develop desmoid tumors. Most often, these tumors develop where surgery was previously performed to remove a small growth (colon polyp) in the colon.
- Trauma: Research has shown that a severe injury, or repeated trauma to the same area (for example, repeatedly hitting the same spot while playing sports), increases the risk of developing a desmoid tumor.
How do doctors diagnose this? (Diagnosis)
If you have these symptoms, your doctor will first do a physical exam and ask about your symptoms. Then, they may do the following tests:
- Imaging tests: The most common are CT scans and MRIs. These can clearly see the tumor inside the body.
- Biopsy: This is the most important test to do . This involves taking a small piece of tissue from the tumor and examining the cells under a microscope. This is the only way to determine exactly what type of tumor it is.
If your doctor suspects that you have FAP, they may do further testing. Not everyone with desmoid cysts has FAP. However, it is important to know if you have it, because people with FAP have a higher risk of developing colon cancer.
How to treat?
Desmoid tumors are often treated in the same way as cancerous tumors. This means that you will likely work with a team of doctors from different specialties, including an oncologist.
In the past, surgery was the main treatment for these tumors. However, since it has been discovered that these tumors have a high chance of coming back after surgery, current treatments are largely based on medications. Other treatments include:
- Active surveillance (or watchful waiting): If your tumor is slowly growing and not causing any major symptoms, your doctor will monitor you regularly. They will do regular scans. If your condition changes, treatment can be started as soon as possible.
- Surgery: Surgery may be necessary if the tumor is growing very quickly or is causing severe symptoms. Or, if the tumor is at risk of causing a serious complication, such as bowel obstruction, surgery may be performed.
- Targeted therapy: These medications work by targeting specific genes or proteins that help desmoid tumors grow. Your doctor may recommend a type of medication called a Tyrosine Kinase Inhibitor (TKI).
- Cryoablation: This is another alternative to surgery. It uses extreme cold to destroy the tumor. This treatment can be used for small desmoid tumors located outside the abdomen (for example, on the arms and legs).
- Chemotherapy: These drugs are used to shrink or completely eliminate desmoid tumors. However, there are varying opinions about the success of this treatment.
- Hormone therapy: Hormonal medications like Tamoxifen can help stop the growth of desmoid tumors.
- Radiation therapy: Radiation can be used to shrink or destroy the tumor. It is used alone or in combination with other treatments.
Do I need to see the doctor regularly? (Follow-up)
Yes, definitely. You will need to see your doctor regularly even after treatment , because desmoid tumors are more likely to come back. You will usually need to have tests and scans every six months for the first three years. After that, if there are no problems, you will need to go for check-ups once a year or every two years. Your doctor will decide how often you need to come, depending on your condition.
What can I expect with this condition? (Prognosis)
Desmoid tumors are not the same for everyone. Some people have them but don't show any symptoms. About two out of ten people have them and they go away without treatment. However, for others, they can grow and become a health risk.
Depending on the nature of the genetic mutation in the tumor, doctors can make some guesses about how aggressive the tumor will be and how likely it is to come back after treatment. But nothing can be said for sure.
Even though it's not cancer, that doesn't mean you should just wait it out. A desmoid tumor is a serious condition that should be monitored by your doctor.
How is the survival rate? (Survival Rates)
Desmoid tumors are not usually life-threatening, but they can be a problem for you to continue to manage.
The most important thing here is the recurrence-free survival rate (`recurrence-free survival rate`) . After five years, this rate can range from as low as 23% to as high as 65%. This largely depends on the nature of the genetic mutation in the tumor.
Your doctor will explain to you what you can expect based on your diagnosis.
Most importantly: expert support
Desmoid tumors can be very unpredictable. They can cause pain, limit movement, or affect nearby organs. This uncertainty can be very stressful. Some tumors grow slowly and may not require immediate treatment, but others require very careful management.
Because desmoid cysts are a rare condition and affect each person differently, it is important to seek treatment from a team of specialists who are experienced in managing these complex conditions. A multidisciplinary approach provides the best chance of managing symptoms and improving quality of life.
What we need to learn from this (Take-Home Message)
Okay, so, from what we've talked about, there are a few important things you need to remember:
- Although a desmoid tumor is not cancer, it is not something to be taken lightly.
- If you have an unusual lump or swelling on your body, especially if it continues to grow or is painful, don't waste time and see a doctor immediately.
- This condition can be a bit complicated, so getting an accurate diagnosis and the support of an experienced medical team will go a long way in helping you live successfully with this condition.
- Don't panic, but be careful. The most important thing is to follow proper medical advice.
If you have any further questions about this, be sure to talk to your doctor. Stay healthy!
