Oh thank you so much. I see my surgeon this week thank you for your time, it is so appreciated.
Hi.
The tiny red lump could be a stitch granuloma that can result secondary to the fibrosis around the suture that was not completely absorbed (in case an absorbable suture was used during the lumpectomy). With this, wound healing will be impaired until the non-absorbed suture is removed. After 9 days, the wound should be healing well already, if not completely healed. You should go back to your surgeon to have it checked.
Good luck.
