Breast, Thyroid & Superficial Lumps

Integrate examination, targeted imaging and tissue assessment instead of interpreting a lump from one feature.

FULL CHAPTER EXPLANATION

Deep Learning — Module 17

Connect the clinical question to modality choice, image appearances, limitations and the next decision.

01

Symptom assessment versus screening

A palpable breast lump or concerning nipple change needs a diagnostic assessment even when a recent screening examination was reassuring. Screening and symptomatic pathways have different purposes. Age, pregnancy, prior imaging and clinical findings influence the initial modality. Mammography uses X-rays, while ultrasound can characterize selected palpable or imaged abnormalities and guide sampling. MRI has specific indications and is not automatically the first test for every lump.

02

Concordance matters

Clinical examination, imaging and pathology should provide a coherent explanation. A benign image or sample that does not fit a suspicious clinical finding needs review for discordance. Describe mass shape, margins and associated distortion or calcification, but do not infer histology from one feature. Image-guided biopsy targets the relevant abnormality, and specimen and imaging results must be checked for adequacy and agreement.

03

Breast density and reporting

Dense fibroglandular tissue can obscure lesions on mammography, and supplementary imaging may be considered through an individualized pathway. Density is not itself a diagnosis of cancer. Standardized reporting categories communicate assessment and management recommendations; suspicious imaging is not the same as a confirmed malignancy. The patient needs an explanation of the next step and its purpose, especially when more imaging or a biopsy is recommended.

04

Thyroid ultrasound

Ultrasound assesses nodule composition, echogenicity, margins, shape, calcifications and relevant cervical nodes. Risk systems combine features and size to guide sampling or follow-up. Thyroid hormone tests answer a different question and normal function does not exclude a malignant nodule. Avoid applying one feature as a universal rule; the report should use the chosen risk system consistently and consider the clinical context.

05

Other superficial masses

Ultrasound can determine whether a palpable abnormality is cystic or solid, its depth and its relationship to nearby structures. A growing unexplained mass may require MRI or a specialist pathway before biopsy or excision. Lymph-node appearance can suggest possibilities but may not establish the cause. Document the exact location and correspondence with the palpable finding so that a normal scan of the wrong site is not mistaken for reassurance.

High-Yield Revision

  • A new symptom can need assessment despite normal prior screening.
  • Check agreement between examination, imaging and pathology.
  • Thyroid function and nodule morphology are different questions.

Common Exam & Concept Pitfalls

  • Dense breasts do not mean cancer is present.
  • A suspicious imaging category is not a tissue diagnosis.
