A comprehensive breast assessment is a key component of the annual gynecological exam. This exam can feel invasive to patients, so it is important to do everything possible to make them feel comfortable and empowered, rather than vulnerable.
In order to avoid missing potential findings, the breast exam should be performed in a systematic manner. The three main components of this exam are visual inspection, palpation of the lymph nodes, and palpation of the breast tissue. In this video, we will first briefly review the anatomy of the breast tissue, and then we will demonstrate the essential steps required to carry out a comprehensive breast examination.
The breast tissue extends from directly under the clavicle to around the fifth rib or bra line. Laterally, it extends from the mid-axillary line to the sternal border. A breast can be viewed in four quadrants: the upper inner, the upper outer, the lower inner and the lower outer quadrant. The upper outer quadrant has the most tissue and is the location of several lymph nodes. It is also the location of the Tail of Spence or the axillary tail, which extends the breast tissue to the edge of the axilla, where it attaches to the chest wall.
First, establish an expectation of comfort. Ask what the patient would like to be called first…"Dialogue". Additionally, the best practice dictates avoiding assumptions about patients' gender, as patients with female anatomy may identify as another gender, for example, transgender or genderqueer…"Dialogue". Then request the patient to communicate their questions and concerns during the visit. For example, ask questions like…"Dialogue".
Before beginning the exam, wash your hands thoroughly. While it is not necessary to wear gloves for the breast exam as long as the patient's skin is healthy and unbroken, a practitioner may choose to wear them to perform the manual portions of the exam. This could be for the sake of the patients, or their own, comfort. If there is a doubt, then it is better to wear gloves, as a patient can pick up on any anxiety, which may make them feel uncomfortable. During the exam, the examiner should be aware of what they are communicating, both verbally and non-verbally, and give their patients control wherever possible. An examiner may choose to utilize a chaperone for the patient's as well as their own comfort. However, we will not be using a chaperone in this video demonstration.
While it is always important to avoid overly clinical language, in a sensitive exam like this one, certain colloquial words can cross the line from being caring to being overly intimate. Therefore, it is helpful to avoid the words "touch" and "feel". Instead, use words like "assess," "check," or "examine". Before starting with the procedural steps, introduce and summarize the three parts of the exam for the patient…"Dialogue".
With the patient seated on the exam table, ask them to lower the gown to their waist. Visually inspect the breast tissue while the patient remains still. Assess for redness, scaly skin, visible lumps, spontaneous discharge, moles, inverted nipples, and dimpling. If you notice something, then, in order to distinguish if it is normal or a recent change, ask the patient about it …"Dialogue"
Also inspect for potential signs of domestic violence and trauma. These include: bruises, burns, bite marks, scars, etc. If you notice any of these, then discuss the cause with the patient.
The next step is to inspect the breast tissue in motion. To do so, first ask the patient to slowly raise their arms above their head, clasp and push them together and then slowly lower them to their sides. Through all the motion steps, the breast tissue should move freely, away from the chest wall, and no tissue should appear to dimple or retract. Then move to one side of the patient; offer your arm, palm down, for support, and ask the patient to lean forward. Observe the side of the breast tissue movement as the patient does so. Then place a hand mirror under their breast. Angle the mirror to see the skin and tissue on the underside. Then ask the patient to sit back and you should angle the mirror accordingly to observe how the lower breast tissue moves during this motion. Repeat the same on the other side. Sometimes this step requires patient standing up. Next, ask the patient to place their hands on their hips and roll their shoulders forward. Observe how the tissue moves.
The next part is the regional lymph node examination. First, assess the supraclavicular lymph nodes. Using your index and middle fingers, hook over the patient's clavicles. Then, using a circle-slide motion, palpate the supraclavicular nodes. Next, examine the axillary lymph nodes, one side at a time. For this, ask the patient to put their gown back on, leaving one shoulder exposed, in this case the right one. Then have them rest their right forearm on your shoulder, while you stand at their side.
Before you begin, inform the patient that they may feel some pressure… To palpate the central nodes, use your right index and middle fingers to push up and under the fatty tissue toward the apex of the axilla. Then press firmly against the upper thoracic wall, which feels like a large, curved bone. From there, palpate down the mid-axillary line to the fifth rib. Drag your fingers across the skin between palpations rather than lifting your hand. This will help in assessment of the most superficial layer of tissue and ensure that no area is skipped. Next, ask the patient to make a fist in order for you to view the line between the biceps and triceps. Subsequently, ask them to release the fist, and then palpate the brachial chain using two fingers of your right hand. Then place your left index, middle and ring fingers behind the patient's pectoralis muscle and your right hand on the front of the chest. This helps you to brace the tissue and assess the pectoral lymph nodes. Apply anterior pressure with your left hand while moving it up and down in a windshield-wiper motion to assess the tissue and nodes. After that move your right index, middle and ring fingers in front of the teres major muscle and keep your left hand on the patient's back. This time apply posterior pressure with your right hand, and move it up and down in a windshield-wiper motion to assess the tissue and the subscapular nodes. Repeat the entire process on the patient's left side.
Following lymph node examination, the last set of steps focus on the clinical breast exam, which involves assessment of the breast tissue using finger pads. There are a few well-accepted approaches for this part of the exam: the concentric circle approach, the radial spoke or wedge technique and the vertical strip or linear method. In this video, we will demonstrate the vertical strip method. However, regardless of the approach, the palpation technique remains the same.
First step is to request the patient to lie down and have them roll away from you and onto their side. Then place a pillow behind their back and ask them to lie flat again. Next, request the patient to lower their gown on the side close to you and raise the corresponding arm over their head. Then, using the pads of three fingers, begin palpating at the top of the mid-axillary line and move vertically down in a circle-slide motion. At each spot, spiral down through three levels of pressure: superficial, medium and deep. Continue to palpate till you reach the fifth rib, then, move an inch over and palpate in a straight line up to the clavicle. Continue to examine the breast in this pattern until finishing at the nipple line. Before passing over their nipple, remember to notify the patient…and then continue.
During this palpation, a healthy breast tissue may feel lumpy as it includes fatty tissue, lobules, ducts, fibrocystic changes, the inframammary ridge and lymph nodes. If all the structures are healthy, then they have clearly defined boundaries and will move freely under your fingers. Unhealthy structure may feel stuck to the tissue around them or matted together.
Next, ask the patient to roll away from you. Move the pillow and place it under the patient's head and ask them to roll back and lay supine. Now continue the exam by re-assessing the nipple line, moving in the vertical strip pattern until you reach the sternal border. Then ask the patient to lower their arm to their side to allow palpation of the infraclavicular nodes and tail of Spence simultaneously. Starting at the mid-clavicular area, palpate directly below the clavicle to the edge of the shoulder. Subsequently palpate back a quarter of the way across the chest in a zigzag pattern, then move to the distal border of the upper outer quadrant to finish checking the superior Tail of Spence. Lastly, to assess the inferior Tail of Spence, place three fingers under the pectoral muscle and move in a windshield-wiper like motion. This concludes the assessment for one side. You should repeat the same steps for the opposite side.
After the examination is complete, ask the patient to put their gown back on. Inform the patient that everything appears healthy and normal, if this is indeed the case. Otherwise, just exit the room and allow the patient to dress. And only after confirming that the patient is dressed, return to the room and discuss the findings and next steps.
You have just watched a JoVE video detailing a comprehensive breast examination. You should now understand the systematic sequence of steps that every physician should follow in order to conduct this exam.
Remember, carefully choosing words while conversing with the patient during the exam, allowing them to take control wherever possible, and following the best clinical practices, will allow you to conduct this examination in a sensitive yet effective manner. As always, thanks for watching!
