Hereditary cancer risk: What you need to know about Li-Fraumeni Syndrome

Have you ever heard of a family history of cancer? Or a young person developing a cancer that usually affects older people? Sometimes there may be a reason behind these things that we don't know. That's what we're going to talk about today, a rare genetic condition that runs in families and greatly increases the risk of cancer. It's called Li-Fraumeni Syndrome.

Simply put, what is Li-Fraumeni Syndrome?

This is a very rare genetic condition. It is caused by a mutation in one of the genes in our body. This genetic change greatly increases the chance or risk of you and your family developing one or more types of cancer.

Consider this: A person with this condition has a 90% chance of developing cancer by the age of 60. And, about half of these people develop cancer before the age of 40. In particular, women with Li-Fraumeni Syndrome have a nearly 100% chance of developing breast cancer in their lifetime.

This may sound a little scary. But the important thing is that although we cannot prevent this condition, by getting early and regular cancer screenings and getting the necessary treatment , we can greatly limit the impact it has on our lives.

How common is this condition?

Li-Fraumeni Syndrome is a very rare condition. Researchers have only found about 1,000 families worldwide with this genetic mutation. So there is no need to be unnecessarily afraid of it.

What are the symptoms of Li-Fraumeni Syndrome?

The special thing here is that there are no specific symptoms associated with the condition called Li-Fraumeni Syndrome. That is, a person with this condition does not see any changes on the outside.

So how do you recognize this? The main sign of this condition is the occurrence of certain types of cancer at a young age . Therefore, the symptoms you experience will depend on the type of cancer you have. For example, brain cancer will show symptoms related to that, and breast cancer will show symptoms related to that.

What types of cancer are most commonly associated with this condition?

More than ten types of cancer have been linked to Li-Fraumeni Syndrome. Some cancers are so common in people with the condition that they are called "core cancers." Let's take a look at what they are.

Why does this situation occur?

To understand why this is, we need to know about a little guard in our body. We have a gene called TP53 . It's like a "guardian angel" in our body. The main function of this gene is to prevent cells in our body from growing abnormally and uncontrollably and becoming tumors.

The protein made by this TP53 gene is called the P53 protein. This is what actually does that guard job.

Now, what happens to someone with Li-Fraumeni Syndrome is that there is a change, or a mutation, in the protective gene called TP53 . What happens is that the gene is unable to produce the P53 protein that works properly. When this protective gene is lost, the cells start to divide uncontrollably. That's what develops into cancer.

Most often, a child inherits this defective TP53 gene from their parents. This is called an Autosomal Dominant Pattern . Simply put, even if only one parent inherits this defective gene, whether it's the mother or the father, the child can still develop the condition and have an increased risk of cancer .

However, very rarely, this genetic change can occur in a person's body without anyone in the family having this condition. This is called a De Novo Mutation.

How is this condition diagnosed?

Doctors use genetic testing to diagnose the condition. But before doing so, they will take a thorough look at your and your family's medical history. There are several reasons why a doctor might suspect Li-Fraumeni Syndrome:

• If you have been diagnosed with sarcoma cancer before the age of 45.
• If one of your first-degree relatives (parents, siblings, children) has been diagnosed with any cancer before the age of 45.
• If any of your second-degree relatives (grandparents, aunts, uncles, nephews, nieces) have been diagnosed with any cancer before the age of 45.

If one or more of these criteria are met, the doctor may refer you for genetic testing.

If you are diagnosed with this condition, the next most important thing is to work on a cancer screening schedule. By seeing your doctor regularly and getting tested, any cancer that does develop can be detected and treated at a very early stage .

How is it treated?

There is no specific treatment for the genetic condition Li-Fraumeni Syndrome. Doctors treat the cancers that result from the condition. The treatments are very similar to those given to someone without the condition. These include surgery and chemotherapy.

But there is a very important exception here.

What should you expect when living with this condition?

Knowing you have Li-Fraumeni Syndrome means that you and your family need to work on a regular cancer screening schedule. Research has shown that regular screening significantly increases the chances of saving lives in these individuals .

These test schedules are different for children and adults. The following is just an example. Your doctor will create a schedule that is right for you.

Can't this situation be prevented?

There's no way to prevent the genetic condition Li-Fraumeni Syndrome. It's something that comes with our genes. But you can avoid things that increase your risk of cancer.

• Avoid smoking completely.
• Avoid excessive alcohol consumption .
• When going out in the sun, don't stay out for too long without protection like sunscreen .

Some women have both breasts surgically removed before cancer develops to reduce their risk of breast cancer. This is called prophylactic mastectomy .

Even with all these precautions, a person with this condition can still develop cancer. That's why the best thing to do is to get regular screenings and catch cancer early if it does occur.

How do you take care of yourself and your family?

Living with a lifelong condition like this can be both physically and mentally challenging.

1. Don't miss screenings: Follow your recommended cancer screening schedule exactly.

2. Family planning: If you are planning to have children, it is very important to talk to a genetic counselor. You need to understand the risk of passing on this defective gene to a child.

3. Mental health: Don't carry this burden alone. Seek the help of a mental health counselor who has experience working with cancer patients or those with chronic illnesses. Ask your doctor about support groups like these.
