Are you aware of this genetic condition that increases your risk of cancer? (MUTYH-Associated Polyposis - MAP)

Maybe someone in your family has had colon cancer. Or has your doctor recently told you that you have some polyps in your colon? It's normal to feel scared and worried when you hear something like this. But when we know exactly what causes it, we can understand how to deal with it. Today we are going to talk about a genetic condition that can cause these conditions, but is not talked about much in society. That is MAP.

Simply put, what is MAP (MUTYH-Associated Polyposis)?

MAP, or `(MUTYH-Associated Polyposis)` is a very rare, inherited genetic condition. This is when small, abnormal growths, or nodules, develop in our bodies, especially in the digestive tract. In medical terms, we call these `(Polyps)`.

Now you might be thinking, "Oh my God, does having polyps mean cancer?" No, these polyps are not cancer. But, the important thing is, some of these, if we don't treat them properly, if we don't remove them, have a high chance of turning into cancer over time.

These ``Polyps`` are most likely to form in the body of a person with MAP:

• Colon
• Rectum
• Small intestine
• Stomach

Is having MAP a cancer risk?

Yes, the honest answer to this question is "yes." A person with MAP has a significantly higher risk of developing colorectal cancer than the average person. In fact, some studies have found that about half of people who are first diagnosed with MAP already have colorectal cancer.

These cancers usually appear between the ages of 40 and 60. But sometimes they can develop even earlier. Also, in addition to colon cancer, there is a certain risk of developing duodenal cancer and other types of cancer outside the digestive system.

Is it possible to live normally with this condition?

It definitely is. This is the most important thing you need to remember. Most people with MAP can live a normal, healthy, full life. But there is one secret to that. That is to recognize the symptoms early and get regular cancer screening tests.

These tests detect and remove the polyps we mentioned earlier before they turn into cancer. Doing so can greatly reduce the risk of developing cancer.

What are the symptoms of MAP condition?

This is where many people get confused. There are no symptoms that you can see or feel on the outside, which is unique to MAP. Even if you have many polyps inside your stomach, you may not feel any pain or discomfort from them.

Therefore, the presence of `(Polyps)` alone is not a good indicator of having MAP. There are several reasons for this:

• Many people have polyps but do not have MAP. Polyps can also develop due to other health conditions.
• There are other genetic diseases that cause `(Polyps)` like MAP. An example is `(Familial Adenomatous Polyposis - FAP)`.
• Sometimes, when someone with MAP is diagnosed, they may not even have a single ``polyp'' in their body.

Simply put, only genetic tests can tell for sure whether you have MAP, FAP, or another condition.

Why does this MAP form? How is it passed down through generations?

MAP is caused by a change, or mutation, in a gene called `MUTYH` (also called MYH). Think of our body as a big recipe book, and genes are the recipes in it. If one letter in the `MUTYH` recipe is wrong, the product it produces won't work properly. MAP is like that.

We call this condition inherited as ``autosomal recessive.'' This means that for you to have this condition, you must inherit this faulty gene from both your mother and father, that is, from both parents.

Imagine that you only got this faulty gene from one person. For example, only from your mother. Then you will not develop MAP disease. But you are called a MAP "carrier". This means that you have the faulty gene, but do not have the disease. If you are a carrier, you can pass this gene on to one of your children.

It is estimated that between 1% and 2% of the world's population are MAP carriers. Carriers also have a slightly higher risk of developing colon cancer than the general population, but not as high as someone with MAP.

What happens to the children if both parents are MAP carriers?

This is very easy to understand. If both parents are carriers, there are three possibilities for each child they have.

How do I know exactly if I have MAP?

The diagnosis of MAP is usually made in several steps.

1. Family medical history: First, your doctor will ask about your family's health history. This includes any history of cancer or other medical conditions in your parents, grandparents, and siblings.

2. Genetic Tests: If your doctor suspects a genetic condition based on your family history, he or she may refer you for genetic testing. This test can determine if you have a mutation in the `MUTYH` gene or other genetic conditions that increase your risk of cancer.

A doctor will typically recommend genetic testing in the following cases:

• If anyone in your family has genetic diseases like MAP or FAP.
• If several members of your family have had colon cancer.
• One of your brothers or sisters has a lot of polyps in their colon, but their parents don't (this raises the suspicion that the parents may be carriers).

If the genetic test confirms that you have MAP or are a carrier, your doctor will talk to you in detail about the next steps and the tests you need to take to protect yourself from cancer. It is also very important to share this information with the rest of your family, as it will help them get tested if they want to.

Treatment and management for MAP

There is currently no "cure" for the genetic mutation that causes MAP. However, there are many tests and treatments that can help us prevent cancer, or detect and treat cancer at a very early stage.

If you have MAP, you may need to undergo cancer screening tests earlier and more frequently than the average person.

Other things to know when dealing with this condition

Can I prevent this from happening to my children?

There is no way to prevent the mutation in the MUTYH gene. However, there are assisted reproductive techniques that can reduce the risk of a future child inheriting MAP. An example is a procedure called preimplantation genetic diagnosis (PGD) that is performed with in vitro fertilization (IVF). This involves testing the embryo for genetic diseases before it is implanted in the mother's uterus. However, this is a very complex decision, both financially and emotionally. If you are interested in this, it is best to talk to a qualified reproductive endocrinologist.

How to stay mentally strong?

When you learn that you have a higher risk of developing cancer, you may feel anxious, scared, and even depressed. This is normal. But don't try to deal with these feelings alone. Talk to your doctor about it. Talk therapy and, if necessary, medication are available.

Also, it would be a great help if you could join support groups where you can talk to people who have had similar experiences. Remember that you are not alone.
