Does Breast Core Needle Biopsy Affect Lymphatic Circulation?

Will performing a core needle biopsy of the breast with aspiration from the outer side draw lymphatic fluid?

Last week, I underwent a core needle biopsy and aspiration due to a larger cyst.
The doctor mentioned that two aspirations were performed to remove the fluid from the cyst.
However, after the biopsy and aspiration, I occasionally experience numbness in my upper arm and shoulder soreness, along with a feeling of weakness in my fingers.
Additionally, there is still swelling a week later.
During my follow-up visit, the doctor performed an ultrasound and stated that there were no signs of infection.
Could this be related to lymphatic circulation?

Hello Ms.
Tsai, based on your question, aspiration or biopsy will not affect lymphatic circulation or cause weakness in the fingers.
The issue of swelling is related to individual constitution and recovery.
Since there are no images to reference, it is recommended that if there is no improvement after some time, you should return to the original hospital and discuss this situation with your attending physician.

More Info

Breast core needle biopsy (CNB) is a minimally invasive procedure used to obtain tissue samples from breast lesions for diagnostic purposes. While it is generally considered safe, there are potential side effects and complications that can arise, including those related to lymphatic circulation.

Lymphatic circulation plays a crucial role in the body's immune response and fluid balance. It is responsible for draining excess fluid from tissues and transporting immune cells throughout the body. When a biopsy is performed, there can be temporary disruption to the lymphatic system in the area surrounding the biopsy site. This disruption may lead to localized swelling, discomfort, or changes in sensation, as you have described with your symptoms of arm numbness, shoulder pain, and finger weakness.

The symptoms you are experiencing, such as swelling and discomfort in the upper arm and shoulder, could indeed be related to the lymphatic circulation being affected by the biopsy. The procedure can cause localized inflammation and fluid accumulation, which may lead to transient lymphedema (swelling due to lymph fluid buildup). This is particularly true if there was significant manipulation of the tissue during the biopsy or if there was any trauma to the lymphatic vessels.

It is also important to consider that the symptoms you are experiencing could be multifactorial. For instance, the positioning during the biopsy, the local anesthetic used, or even the stress and anxiety associated with the procedure can contribute to sensations of numbness or weakness. Additionally, if there was any bleeding or hematoma formation at the biopsy site, this could also lead to swelling and discomfort.

In your case, the absence of infection as confirmed by ultrasound is reassuring. However, if the swelling persists or worsens, or if you develop new symptoms such as fever, increased pain, or changes in skin color, it is essential to follow up with your healthcare provider. They may consider further evaluation to rule out other complications or to assess the lymphatic function in the affected area.

To manage your current symptoms, consider the following recommendations:
1. Rest and Elevation: Try to keep your arm elevated to help reduce swelling. Resting the arm can also alleviate discomfort.

2. Compression: If advised by your healthcare provider, wearing a compression garment may help manage swelling.

3. Gentle Range of Motion Exercises: Once the initial discomfort subsides, gentle stretching and range of motion exercises can help maintain mobility and reduce stiffness.

4. Pain Management: Over-the-counter pain relievers, such as acetaminophen or ibuprofen, may help alleviate discomfort.

5. Follow-Up: Keep in close contact with your healthcare provider regarding your symptoms. If they persist beyond a reasonable timeframe or worsen, further evaluation may be necessary.

In conclusion, while a breast core needle biopsy can affect lymphatic circulation temporarily, the symptoms you are experiencing should be monitored closely. It is essential to maintain open communication with your healthcare provider to ensure appropriate management and to address any concerns you may have regarding your recovery.
