From your description and the images, this appears most consistent with a clogged Montgomery gland / small areolar pimple that has been irritated due to repeated squeezing. These glands can get blocked and drain whitish material, and mild redness or a small soft bump may persist for some time. The fact that your breast USG was normal and the bump is soft, skin-coloured and not painful is reassuring.
At this stage, it does not look worrisome and usually settles with simple care as long as the area is left undisturbed.
Next Steps
• Avoid squeezing or pressing the area further — this delays healing and can cause infection.
• Apply a warm compress 1–2 times daily for 5–7 days.
• You may apply a topical antibiotic (mupirocin / fusidic acid) twice daily for 5 days if there is mild redness.
• Keep the area clean and dry; avoid friction from tight clothing.
• If the bump becomes painful, rapidly increases in size, becomes very red, or if fever appears — seek an in-person breast exam to rule out infection or abscess.
• If the bump does not improve in 2–3 weeks, consider a revisit for clinical evaluation.
Health Tips
• Most Montgomery gland blockages are harmless and settle without intervention.
• Manipulation is the most common cause of recurrence — hands off is the key to healing.
• Since your previous ultrasound was normal and the features are benign-looking, there is no immediate concern for breast cancer.
