Lymphedema is a condition that can occur when a part of the lymph system, such as a vessel or node, is blocked. This blockage then causes a build-up of fluid that can lead to pain and swelling, typically in a limb. Lymphedema is fairly common in cancer patients and can be a result of cancer treatment. Keep reading to learn more about lymphedema and cancer, whether cancer can cause lymphedema, and how to prevent this medical condition.


What Is Lymphedema?

Your body is made up of several different systems, each of which has a specific job to do. Your lymph system consists of lymph nodes, vessels, and fluid which is carried throughout the body and filtered through the nodes. The lymphatic system plays an important role in the body’s immune response to help fight off infections and maintain normal fluid balance. However, when lymph nodes or vessels become damaged or blocked, the fluid can build up, causing localized edema or swelling.

Lymphedema is a chronic condition that results in swelling that occurs most often in your arms and legs, but can occur anywhere in the body. As excess fluid accumulates in your body, it can lead to chronic swelling, pain, and discomfort if left untreated. If not managed daily, lymphedema becomes a progressive condition.

There are several causes of lymphedema, with treatments for cancer being one of the most common. Cancer survivors should be educated on the risk of lymphedema when going through treatment for their disease. This is why it’s important to understand the correlation between lymphedema and cancer as a cancer survivor.

Is Lymphedema Caused By Cancer?

Can cancer cause lymphedema? The short answer is yes. However, lymphedema isn’t typically caused by cancer itself, but by the treatment that doctors use to remove cancer from your body. Because lymphedema is caused by damage to the lymphatic system, damage to lymph nodes or lymph vessels can lead to lymphedema.

During surgery to remove cancer, surgeons may remove lymph nodes to test if they are positive for cancer. Removing these positive lymph nodes is necessary to help prevent the spread of cancer. While not every person undergoing treatment for cancer will develop lymphedema, it is the most common side effect.

In some cases, lymphedema in cancer patients can be caused by radiation therapy that’s used to kill and slow the growth of cancerous cells. Radiation is very hard on your body in several ways, and that can include damage to your lymph nodes and vessels. As radiation damages these cells and causes a build-up of scar tissue, your lymph system may be obstructed at some point.

Can Lymphedema Be a Sign of Cancer?

Because lymphedema and cancer are often closely associated, you may wonder if lymphedema can be a sign of cancer. While lymphedema is often caused by cancer or cancer treatment, severe lymphedema that goes untreated can, in rare cases, develop into a type of soft tissue cancer in the lymphatic system, called lymphangiosarcoma.

In most cases, lymphedema occurs from scar tissue and the destruction of lymph nodes and vessels due to radiation or the removal of lymph nodes through surgery. Occasionally, the cancer tumor itself can obstruct the flow of the lymphatics, depending on the location and size of the tumor.

Most patients who are diagnosed with lymphedema as a result of cancer are diagnosed with it after they’ve received treatment, such as radiation or a surgical procedure. Of course, it’s always best to visit a doctor to review your symptoms for a proper diagnosis and to determine the best course of treatment.

How to Manage Lymphedema After Cancer

If you’ve been diagnosed with lymphedema after cancer treatment, one of the first steps to take is to educate yourself and learn how to manage symptoms. Lymphedema is chronic and causes pain and discomfort, which can impact your quality of life. Fortunately, there are several at-home management tools that don’t involve surgery or medications.

At Tactile Medical, we have several lymphedema treatment and management solutions that can help alleviate the symptoms associated with lymphedema right at home.

Complete Decongestive Therapy also includes education on the importance of skin scare and exercise to manage symptoms.

If you’ve been diagnosed with lymphedema after cancer, consult with your doctor and a lymphedema specialist. They can provide management and treatment solutions, as well as prescribe at-home lymphedema therapy, such as lymphedema pumps and compression garments.


What Kind of Cancer Causes Lymphedema?

While there are several types of cancer with treatments that may cause lymphedema, such as those that require lymph node removal, certain types of cancer come with a higher risk of lymphedema.

Treatment for breast cancer is one of the most common causes of lymphedema in the arms, chest, or trunk because the removal of cancerous tissue often requires the removal of the lymph nodes that are located in your underarms. When it comes to uterine cancer, prostate cancer, vulvar cancer, and ovarian cancer, lymphedema in the lower part of the body including the legs, buttock, and genital region can occur.

Lymphoma is a type of cancer that specifically affects the lymph system and may lead to lymphedema.

What Percentage of Cancer Patients Develop Lymphedema?

According to one study, about 42% of breast cancer patients developed lymphedema, where most were mild cases. Another study examined the prevalence of lymphedema in patients who experienced other types of cancer. You can find all the data from this study below:

  • Melanoma: 16%
  • Gynecologic: 20%
  • Genitourinary: 10%
  • Head/neck: 4%
  • Sarcoma: 30%
  • Patients undergoing pelvic dissections: 22%
  • Patients undergoing radiation therapy: 31%

Lymphedema is underdiagnosed in cancer survivors. If you’re experiencing any chronic swelling symptoms associated with lymphedema after cancer, consult with your doctor.
