What Is a Phyllodes Tumor


 

Overview
A phyllodes tumor is a rare tumor of the breast. Phyllodes tumors grow in the connective tissue of your breast, called the stroma.

The American Cancer Society says that most phyllodes tumors aren’t cancerous, so they don’t often spread outside your breast. However, they can grow quickly. Some phyllodes tumors are between benign and cancerous. These types are considered “borderline.”

Causes
The cause of phyllodes tumors is unknown. They may just arise as people age.

Several factors may be involved in causing these tumors to grow, including:

injury

breastfeeding

pregnancy

increased levels of estrogen, a female hormone

Symptoms

Phyllodes tumors grow very quickly. Breastcancer.org says that the first symptom is often a lump under your skin. The lump will feel smooth to the touch. The skin over your breast might also turn red or discolored and feel warm. The tumor may grow quickly enough that you can eventually see it under your skin.

Even though most phyllodes tumors aren’t cancerous, they can grow and cause pain. If the tumor breaks through your skin, you might see an open sore on your breast.


Treatment
Even when a phyllodes tumor is benign, it can grow and cause pain and other problems. Your doctor will recommend that you have surgery to remove it. The surgeon will remove not only the tumor, but also some of the healthy tissue around it.

Breastcancer.org says that a few different types of surgery are used to treat phyllodes tumors. The type of surgery a person may receive depends on the size of the tumor and the patient’s preferences.

Lumpectomy. The surgeon removes the tumor, along with at least 1 centimeter (0.4 inches) of tissue around it. Removing this extra tissue helps prevent the tumor from coming back.
Partial mastectomy. If the tumor is larger, the surgeon will remove the entire part of the breast that contains it.
Total mastectomy. The surgeon removes the whole breast. You can have breast reconstruction surgery at the same time, or after the mastectomy.
If the tumor is cancerous, your doctor may recommend these treatments:

Radiation uses high energy waves to kill cancer cells. Your doctor can use it after surgery to treat a cancerous phyllodes tumor that hasn’t spread outside of your breast.
Chemotherapy uses chemicals to kill cancer cells throughout your body. This treatment is an option if a cancerous tumor has spread to other parts of your body.
