Let's learn simply about lymphadenectomy during cancer surgery.

You've probably heard the doctor say, "We need to remove some lumps" when you find out that you or someone you know has cancer. It's normal to feel a little scared and curious at that time. What are these lumps? Why are they removed during cancer treatment? Is this surgery dangerous? Today, we'll talk about all this very simply, in a way that you can understand.

What is Lymph Nodes and Lymphadenectomy surgery?

Okay, first let's look at what these little guys are. We have a network of vessels throughout our bodies, just like blood vessels. We call this the Lymphatic System . One of the main functions of this system is to help protect our body.

Imagine that the lymphatic system is like a network of roads in our country. Then the lymph nodes are like police checkpoints located along those roads. These checkpoints capture and filter waste, germs, damaged cells, and especially cancer cells in our body. So these are like the guards in our body.

Simply put, Lymphadenectomy is the surgical removal of one or more of these lymph nodes.

Why do you need this surgery?

Typically, a doctor will recommend this surgery to someone who has already been diagnosed with cancer. There are two main reasons for this.

1. Diagnosis and Staging: The lymphatic system is the main route through which cancer cells spread from one place to another. So, by removing and examining a few nodes near the tumor, we can know exactly whether the cancer has spread outside the tumor (Metastasis). We call this determining the stage of the cancer (Cancer Staging). Based on this stage, doctors decide what treatment method (e.g., chemotherapy, radiation therapy) is most suitable for you.

2. As a treatment: If the removed lumps are found to contain cancer cells, it means that the cancer cells were also removed during the surgery. Also, if the cancer has spread, this surgery can help to remove more lumps and stop the cancer from spreading further in the body.

What are the main types of surgery?

This surgery can be divided into two main types. There is also a special method.

Sentinel Node Biopsy

Sometimes surgeons will first remove and examine only the node closest to the tumor, which is like a "first checkpoint" where cancer cells can spread first. This is called a Sentinel Node Biopsy . If that node does not contain cancer cells, it is very unlikely that other nodes will also contain cancer cells. In that case, major surgery may not be needed.

Where on the body do you remove moles?

Moles are not in one place on our bodies, but in clusters. Which cluster is removed depends on where the cancer is. Different types of cancer spread through different clusters of moles.

Important: The word "Cervical" has two meanings!

The surgery to remove the lymph nodes in the neck is called `(Cervical Lymphadenectomy). Here, ``Cervical'' means related to the neck. Cancer of the cervix is ​​called ``Cervical Cancer.'' These two are completely different. So don't be alarmed by hearing the word. Your doctor will explain it to you.

What happens during and after the surgery?

Before surgery, your doctor will do things like scans to check the condition of the testicles. They may also do a needle biopsy, which involves taking a small sample of tissue.

The surgery is performed under general anesthesia, so you won't feel any pain. It can be done as an open surgery (through a single incision) or laparoscopic surgery (through several small incisions with a camera). After the stitches are removed, a drain is placed in the wound to stop fluid from accumulating. This is removed by the doctor after a few days or weeks.

You will need to stay in the hospital for a day or two after the surgery. The pain is usually mild and can be controlled with ordinary painkillers.

What are the risks and possible complications of this surgery?

Like any surgery, this one has minor risks.

• Wound infection.
• Damage to the nerves causes numbness or stiffness in the area.
• Blood clotting.

The most common and long-term complication that can occur after surgery is a condition called Lymphedema .

What is Lymphedema?

When a lot of fat is removed, the lymph fluid's flow becomes blocked. Then that fluid builds up in an arm or leg, causing swelling. This is called `Lymphedema`. This may come and go for a short time for some, but for others it can be permanent. This risk is slightly higher if you are also receiving chemotherapy or radiation therapy. But there are now good treatments and exercises to manage it.

What symptoms should I see a doctor for?

When you go home after surgery, watch out for the following symptoms. If you have any of these, call your doctor immediately.

• The wound becomes red, oozing pus, or has a fever (signs of infection) .
• Uncontrollable pain, numbness, or stiffness.
• Difficulty moving limbs and fingers properly.
• Unusual swelling in the arm, leg, or fingers on the side of the surgery (may be a sign of lymphedema).
