What are the treatment options for a lump?

Treatment Options for Lumps

The treatment approach for a lump depends primarily on its location, size, and characteristics, with options ranging from surveillance to surgical excision based on the risk of malignancy.

Diagnostic Evaluation Before Treatment

Before determining treatment, proper evaluation is essential:

1. For breast lumps:

   • Women ≥40 years: Diagnostic mammography/digital breast tomosynthesis (DBT) as first step 1
   • Women 30-39 years: Ultrasound as initial evaluation, though mammography may also be appropriate 1
   • Women <30 years: Ultrasound as first line of investigation 1

2. For pulmonary nodules:

   • Quantitative assessment using validated models with regional considerations 1
   • Size-based evaluation (>8mm vs ≤8mm) 1

3. For gastrointestinal nodules:

   • Endoscopic ultrasound assessment for esophago-gastric or duodenal nodules ≤2cm 1
   • Core needle biopsies for larger masses 1

Treatment Options by Location

Breast Lumps

1. Simple cysts:

   • If definitively characterized as benign on ultrasound, clinical follow-up is appropriate 1

2. Complex cysts:

   • Core needle biopsy is recommended for complex cysts due to higher malignancy risk (14-23%) 2
   • Avoid aspiration as primary management 2

3. Solid masses:

   • For suspicious masses: Image-guided core needle biopsy (preferred over fine-needle aspiration) 1
   • For palpable masses with benign features: Follow-up at 6-12 months for 1-2 years 2

4. After biopsy:

   • Benign, image-concordant: Follow-up every 6-12 months for 1-2 years 2
   • Benign but image-discordant: Surgical excision 2
   • Atypical/malignant: Surgical management per breast cancer guidelines 2

Pulmonary Nodules

1. Solid nodules >8mm:

   • Low probability of malignancy (<5%): Serial low-dose CT surveillance at 3-6 months, 9-12 months, and 18-24 months 1
   • Moderate probability (5-60%): Consider PET imaging before deciding on surgery or surveillance 1
   • High probability (>60%): Surgical diagnosis, preferably thoracoscopic wedge resection 1
   • Non-diagnostic biopsy: Surveillance if not hypermetabolic on PET 1

2. Solid nodules ≤8mm:

   • Size-based surveillance protocol:
     • ≤4mm: May not require follow-up 1

     • 4-6mm: Annual CT if stable 1

     • 6-8mm: CT at 6-12 months, then 18-24 months if stable 1

Gastrointestinal Nodules

1. Small nodules (≤2cm):

   • Standard approach: Endoscopic ultrasound assessment and follow-up, reserving excision for growing nodules 1
   • Alternative: Shared decision-making for immediate histologic assessment 1

2. Larger nodules (>2cm):

   • Standard approach: Biopsy/excision due to higher risk 1

3. Rectal nodules:

   • Standard approach: Biopsy/excision after ultrasound assessment regardless of size 1
   • Follow-up may be an option for small lesions after shared decision-making 1

Common Pitfalls to Avoid

1. Inadequate evaluation:

   • Many women with breast lumps do not receive adequate evaluation 3
   • Higher risk for uninsured women, obese women, and certain ethnic groups 3

2. Relying solely on mammography:

   • Normal mammogram alone is not adequate to exclude cancer in a woman with a palpable breast lump 3

3. Inappropriate biopsy technique:

   • Using FNA when core biopsy would be more appropriate for complex lesions 1
   • Not placing biopsy marker clips during image-guided procedures 1

4. Failure to correlate imaging with clinical findings:

   • Discordance requires further evaluation 2

Remember that the goal of treatment is to rule out malignancy while minimizing unnecessary procedures. The approach should be guided by evidence-based risk assessment and appropriate diagnostic evaluation.
