Sentinel Node Biopsy-----[Existing Visuals II]

This series was created by Ms. Terese Winslow, a medical artist based in Washington DC. It's a pity I couldn't find the original text/document these images were published for; it seems that the images are freely distributed among the web to all sorts of content.

Source: Medical Illustrator Portfolio
Purpose: To provide an abridged overview for the SNB procedure
Target audience: Patient/family

Strengths:
- Clear and concise, provides the essential details for the SNB procedure
- All key steps are accurately depicted (e.g. Injection site, location of sentinel lymph nodes etc)
- Minimalistic, anything that is unrelated to the procedure is omitted, thus focusing attention solely on the breast, axilla and underlying lymph nodes
- Non-traumatic, will not bring about anxiety to patient or their families by introducing surgical fields

Weaknesses:
- Patients/families who are interested in learning more may not obtain more information based on this illustration series; accompanying text can only fill in details to a certain extent
- Seems to elicit the idea that the procedure's only goal is to identify and eliminate cancerous tissue (tumor and affected lymph nodes); in reality, SNB is also used for staging and prognosis of breast cancer
