You may be wondering why I keep getting strange lumps all over my body, or why some diseases just won't go away. Sometimes the reason for this can be a little more complicated than we think. Today we're going to talk about a rare but very important condition to be aware of. That's von Hippel-Lindau disease, or we call it `(VHL)` for short.
What is von Hippel-Lindau (VHL)? Let's understand it simply.
Okay, now you're probably wondering what this `(VHL)` is. Simply put, von Hippel-Lindau is a rare genetic condition. It occurs when there is a `(genetic mutation)` or change in some of the genes in your body. Because of this, you are more likely to develop `(malignant)` tumors, as well as `(benign)` tumors and cysts, in various parts of your body. Doctors sometimes call this condition `(von Hippel-Lindau syndrome`.
Research has found that 97% of people with this genetic mutation will develop these and other VHL-related tumors by the age of 65. In most cases, the main treatment for VHL-related tumors is surgery to remove the tumors.
What cancers can be associated with VHL disease?
If you have this `(VHL)` condition, you are at increased risk of developing one or more of the following types of cancer:
- Clear cell renal carcinoma (ccRCC): This is the most common type of kidney cancer. According to experts, between 25% and 60% of people with VHL can develop this cancer. Remember, the kidneys are one of the most important organs in our body, so cancer in them is something to be very concerned about.
- Pancreatic neuroendocrine tumors (pancreatic NETs): These are a rare type of tumor that starts in the endocrine cells in your pancreas. They can develop in between 9% and 17% of people with VHL.
- Pheochromocytoma: This is a rare but treatable tumor that develops in the adrenal gland. These tumors may start as noncancerous tumors, but can later become cancerous. They occur in 10% to 20% of people with VHL.
- Broad ligament cystadenomas: This condition affects women. It occurs in about 10% of women with VHL. It is a tumor that forms near the fallopian tubes.
What are the non-cancerous tumors that come with VHL?
Not only cancer, but also non-cancerous tumors, that is, tumors that do not spread to other parts of the body (metastasize), can develop when VHL is present. The most important of these is hemangioblastoma.These are non-cancerous tumors that form in the blood vessels of the brain, spinal cord, or retina. Although they do not spread, they can grow large and affect surrounding tissue, causing serious health problems.
The types of hemangioblastomas that can be seen associated with `(VHL)` are:
- Retinal hemangioblastoma: This is a type of tumor that develops in the eye. It can even lead to vision loss. Research suggests that it develops in 60% of people with (VHL).
- Brain stem and cerebellar hemangioblastomas: These are tumors in the brain. They can affect your balance and cause other problems. They affect between 13% and 72% of people with VHL.
- Spinal cord hemangioblastoma: This type of hemangioblastoma develops in between 13% and 50% of people with (VHL).
In addition, if you have VHL, you are also at risk of developing non-cancerous tumors and cysts such as:
- Epididymal cystadenomas: These are tumors that affect men. They develop in the epididymis, a small tube-like structure that stores sperm, near the testicles. They occur in between 25% and 60% of men with VHL.
- Endolymphatic sac tumors (ELST): These are very rare tumors. If you have VHL, they can develop in the inner ear. This condition affects between 10% and 25% of people with VHL.
- Cysts: These are fluid-filled cysts. People with VHL can develop these cysts in the kidneys and pancreas.
How common is VHL disease?
This is actually a very rare condition. It affects about one in 36,000 people. Most people with VHL start to show symptoms in their mid-20s. This means you have to be careful about this at a young age.
What are the symptoms of von Hippel-Lindau disease?
Because this condition can cause tumors to form all over your body, symptoms can vary. It depends on where the tumors are and the size of the tumors. You may experience symptoms like these:
- Frequent headaches.
- Hearing loss or constant ringing in the ears (tinnitus).
- High blood pressure.
- Loss of balance while walking.
- Decreased muscle strength or difficulty coordinating movements.
- Vision issues.
- Vomiting.
Just imagine, how worried we would be if we had one or two of these symptoms? So if you have several of these symptoms at once, it is definitely important to seek medical advice.
What causes VHL disease?
Von Hippel-Lindau syndrome is an inherited disorder . It occurs when you inherit an abnormal copy of a tumor suppressor gene called VHL from one of your parents.
Simply put, these ``tumor suppressor genes`` stop cells from dividing too quickly, which can lead to cancer. It's like the brakes on a car. But if these genes are mutated, it's like removing the brakes and putting the accelerator on. Cell growth accelerates uncontrollably.
The disease is transmitted in an autosomal dominant inheritance pattern. This means that if one of your parents has the abnormal VHL gene, you have a 50% chance of inheriting it and developing von Hippel-Lindau disease. However, research has shown that about 10% of people with VHL have no family history of the disease. This means that new genetic mutations can also occur.
How is VHL disease diagnosed?
Doctors may suspect that you have VHL if you have symptoms of a condition caused by VHL, such as hemangioblastoma or clear cell renal carcinoma. But the only way to confirm this is through genetic testing. If someone in your family has Von Hippel-Lindau disease, it is important to ask your doctor about genetic testing for you.
What are the treatments for VHL disease?
Treatment options vary depending on the type of VHL tumor or cyst. Your doctor will explain the treatment options that are right for you. The most common treatments are:
- Surgery to remove the tumor.
- Chemotherapy.
- Radiation therapy.
- Targeted therapy includes things like peptide receptor radionuclide therapy (PPRT) and tyrosine kinase inhibitors (TKI).
- Immunotherapy.
- Hormone therapy.
The most important thing is to diagnose the disease early and start the appropriate treatment. Only then can you get the best results.
Can VHL disease be completely cured?
Unfortunately, there is currently no cure for von Hippel-Lindau disease. The main goal of treatment is to find and remove the tumors as soon as possible. Your doctor may recommend surgery to remove the tumors, along with other treatments.
If I have VHL, what should I expect?
If you have this condition, you will need to have regular tests to check for signs of certain diseases. Early detection and treatment of tumors can help reduce the impact that von Hippel-Lindau disease has on your life. That's why it's important to get the tests your doctor recommends.
Can VHL disease be prevented?
No, it cannot be prevented. This is because von Hippel-Lindau disease is caused by a genetic mutation passed from one parent to another. If someone in your family has VHL, genetic testing can help you find out if you also have the mutation.
Although you can't prevent von Hippel-Lindau disease, it's helpful to know your risk and understand how `(VHL)` can affect you. If you know you're at risk, doctors can watch for signs of `(VHL)`-related tumors and take steps to remove them early.
If you have the (VHL) gene and are planning to have a child, it is a good idea to meet with a genetic counselor to discuss the risk of your child inheriting the gene.
Are there any special screening tests for VHL-related conditions?
There are no specific screening guidelines for this, as there are for other types of cancer (such as the cancer screening recommended by the US Preventive Services Task Force). However, if genetic testing confirms that you have an abnormal VHL gene, your healthcare team may recommend certain tests to help detect problems early. For example, they may recommend that you have an abdominal magnetic resonance imaging scan (MRI) every two years to check for VHL-related cancers, such as clear cell renal carcinoma.
How can I take care of myself? What can I do?
Living with VHL means living with some uncertainty. If you inherit the genetic mutation that causes VHL, you have a 50% chance of developing the condition. If you do, you have a 97% chance of developing certain types of cancer and other serious illnesses.
However, no one can predict exactly how `(VHL)` will affect your life. Here are some things that can help you manage these challenges:
- Get mental health support: One study has shown that a diagnosis of VHL can have a psychological impact, such as anxiety and panic attacks. Therefore, it is very important to talk to a psychiatrist or counselor.
- Protect your overall health: Eat a balanced diet – lots of lean meats, whole grains, leafy greens, and fruits. Exercise (which can also reduce stress). Ask your medical team about the vaccines that are right for you.
When should I seek medical advice?
If you experience symptoms like these, you should call your doctor immediately:
- Changes in your vision or hearing.
- Frequent headaches.
- Nausea or vomiting that is not thought to be caused by another illness.
- A sudden increase in blood pressure.
- If you suddenly have difficulty walking, maintaining balance, or coordinating movements.
What questions should I ask my doctor?
Imagine you have been told that someone in your family has von Hippel-Lindau disease. If so, here are some questions you can ask your doctor:
- What do my genetic test results say?
- Should the rest of my family get genetic testing?
- How often should I get tested to detect early signs of conditions that may be associated with `(VHL)`?
Finally, things to remember (Take-Home Message)
Von Hippel-Lindau disease (VHL) is a rare genetic disorder. It affects one in 36,000 people. So, finding out that you are one of those 36,000, can be a big shock, especially if no one in your family has had the disease before.
If genetic testing confirms that you have (VHL), give yourself some time to process the news. Then, take time to understand what your diagnosis means. For example, you may have questions about your risk of developing different types of cancer and tumors, or how your diagnosis will affect others in your family. Never hesitate to ask your medical team about what to expect. And don't forget to ask for help to manage the stress that comes with living with (VHL). You are not alone, and there are many people who can help you on this journey.
👩🏽⚕️ Additional questions (FAQs)
💬 Is vaginal discharge always a disease?
No! A woman's vagina is a naturally self-cleaning organ. It is perfectly normal to have a small amount of clear or milky white discharge (odorless) every day. However, if it turns yellow, has a fishy odor, and causes itching in the vaginal area, it is an infection.
💬 Why does the discharge turn yellow and cause inflammation?
A 'curdled white' discharge with severe itching is a sign of a yeast infection (Yeast infection/Candida). A fishy, gray discharge is a sign of a bacterial infection (Bacterial Vaginosis). A yellow/green pus-like discharge may be a sign of a sexually transmitted disease (STD) such as Trichomoniasis/Gonorrhea.
💬 Is it okay to use a 'Vaginal Wash' to avoid this?
Never! Do not douche with vaginal washes, soaps, or perfumes purchased from pharmacies! This will kill the good bacteria (Lactobacillus) in it and make the disease worse. All you need to do is wash and wipe with plain water and wear only cotton underwear. If there is abnormal discharge, you should seek treatment from a doctor.
