Starting From Psychological Stress And Neuroendocrine Responses

Breast biopsy brings not only minor physical trauma but also huge psychological impact. The "fear of cancer" often plunges patients into extreme stress. This psychological state, through complex neuroendocrine mechanisms, affects the surgical experience and postoperative recovery. Therefore, managing psychological behaviors before the procedure is itself an important therapeutic measure.
1. Avoid "Catastrophic Thinking" and Excessive Online Searches
In the days waiting for the biopsy, many patients uncontrollably search online for various terrible outcomes. This behavior is called "catastrophic thinking"; it activates the amygdala in the brain, releasing large amounts of adrenaline and cortisol. These stress hormones increase heart rate, raise blood pressure, and tense muscles.
From a physiological perspective, tense chest muscles and tight fascia harden the breast tissue, increasing the resistance and discomfort when the biopsy needle enters. At the same time, high levels of stress hormones lower the pain threshold, making patients unusually sensitive to what would otherwise be mild stinging sensations. This is why, with the exact same needle, a relaxed patient may only feel slight soreness, while an extremely anxious patient feels unbearable pain.
Recommendation: Limit the time spent searching for information online and only trust the information provided by your attending physician. You can try mindfulness breathing exercises: inhale for 4 seconds, hold for 4 seconds, exhale for 6 seconds, repeat for 5 minutes daily to effectively reduce sympathetic nervous system excitability.
2. Avoid Fasting or Hypoglycemic States
Many patients, due to nervousness, cannot eat, or even deliberately skip breakfast, thinking it will "reduce the burden." This is a serious misconception. In a hypoglycemic state, the body initiates a stress response, releasing more adrenaline, leading to palpitations, tremors, and cold sweats. These symptoms further intensify the patient's panic and may even induce vasovagal reflex (needle fainting).
More importantly, hypoglycemia weakens the brain's ability to regulate pain signals. When the brain's energy supply is insufficient, the activity of descending analgesic pathways (such as the endogenous opioid system) decreases, making the patient feel more pain. Therefore, unless specifically instructed by the doctor (such as needing sedation anesthesia), patients should eat a light breakfast normally on the day of the biopsy, such as porridge, bread, bananas, etc.
3. Avoid Exchanging "Horror Stories" with Others
In the waiting area, patients often exchange experiences with each other. However, negative examples like "it took three punctures to get a sample" or "passed out from the pain" spread like a virus to others. This "empathic pain" will, through the mirror neuron system, cause the listener's brain to generate pain signals similar to actual experiences.
The best approach is to wear headphones and listen to soothing music, or read a light book, proactively disconnecting from negative information. Family members should also avoid repeatedly emphasizing "don't be afraid" or "it doesn't hurt" before the procedure, as such suggestions can actually reinforce fear.
4. Avoid Hiding Past Histories of Needle or Blood Phobia
Some patients, out of shyness or fear of trouble, hide their tendency to faint at the sight of needles or blood. This is a very dangerous behavior. When syncope occurs, the patient's blood pressure drops sharply and heart rate slows; if this happens during the puncture process, sudden postural changes may cause the needle tip to shift or break.
The correct approach is: when signing the informed consent form, clearly inform the doctor of your history of syncope. The doctor will arrange for the puncture to be performed in a supine position and prepare rescue medications and equipment. This is by no means causing trouble, but taking responsibility for your own life safety.
Summary:
Psychological stress is the "invisible enemy" during the biopsy process. By avoiding catastrophic thinking, maintaining normal blood sugar, blocking negative information, and communicating honestly, patients can actively break the vicious cycle of "fear-pain-more fear," making the biopsy process calmer and safer.
