The appearance ,a round bump with mild redness, present for weeks, not painful, and releasing a little watery or oily fluid when pressed is typical of:
1. Sebaceous cyst (oil gland blockage)
2. Epidermal inclusion cyst
3. A healed pimple with a blocked opening
These are benign and very common on the breast, because the skin here has many oil glands.
Next Steps
• Apply a warm compress 10 minutes twice daily
(this helps open the blocked gland)
Avoid squeezing
Apply Mupirocin ointment if the skin looks a little irritated,Keep the area clean and dry
You can watch it for 7–10 more days.
Health Tips
Do you need to see a doctor?
Yes, its always wise to visit a doctor because we have to examine the swelling throughly and look for any lump at other sites which as a patient you might not be aware of.
But,You should visit a doctor immediately if:
it is not reducing at all
it becomes painful
it becomes red/hard/warm
it starts growing
discharge turns thick, foul-smelling or bloody
Right now, it appears mild and harmless. Good luck!
