Lymphatic & Immune / VISUAL EXPLAINER
ποΈ How Cancer Cells Travel Through the Lymphatic System
Cells that leave a primary tumor can be carried in lymph toward a draining node. Transport does not guarantee survival or growth. Cancer arriving from elsewhere is different from lymphoma arising in lymphocytes.

What the illustration shows
Portrait medical poster titled βποΈ How Cancer Cells Travel Through the Lymphatic System.β A subtitle identifies one possible route from a primary tumor into local lymphatic drainage. Against a navy background, a peach tissue patch at left contains coral illustrative tumor cells. A translucent blue afferent lymphatic carries several cells toward the upper convex surface of an ivory cutaway draining lymph node at right. A cyan arrow indicates lymph flow toward the node. The route opens into the subcapsular sinus just under the capsule. Rounded follicles lie around the outer cortex, surrounding a paler central medullary region. Red and blue hilar blood vessels are separate. The lower-left enlargement labels an endothelial wall around a fluid-filled lymphatic lumen containing a tumor cell. The lower-right enlargement shows afferent entry into the subcapsular sinus. Notes state that detached cells can be carried in lymph, transport does not guarantee survival or growth, and this is a possible route rather than inevitable spread or a cancer stage. A further note distinguishes cancer arriving from elsewhere from lymphoma. Cell appearance, counts and fine nodal architecture are illustrative. Gold AllHumanBody.com branding and the complete slogan appear on a plain navy footer.
How to interpret this poster
- Possible route, not inevitable spread, guaranteed colonization, node-first sequence or cancer stage. Cell morphology/counts illustrative; no node-size diagnosis, survival percentages, sentinel test or prognosis.
- AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
- Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
