Hi Wooda, I had left mastectomy with immediate reconstruction and sentinel node biopsy with 4 other nodes removed. I had two drains initially with first drain removed after two weeks but had my second drain for eight weeks! I was told it had to be under 20mls for two consecutive days. I didn't make that level. At the eighth week my surgeon removed the drain as she said it was quite possible it was the drain causing irritation and was keeping the levels at around the 40ml mark. Once the drain was removed I didn't even get a seroma. All good!! Hope this helps!! Xx Cath
