You must be tired and concerned after the ER visit, the fevers, etc. Antibiotics cannot clear off the fluid around lumps. You can and probably should go back for repeat testing if you are highly concerned.I am unsure when you had your breast augmentation surgery, but I would like to share some information from a recent research review paper on breast-implant associated anaplastic large cell lymphoma (Clemens, M. W., & Miranda, R. N. (2015). Coming of Age. Clinics in Plastic Surgery, 42(4), 605–613). I summarize the information below for your knowledge.Since 2011, the FDA has published a warning on the safety profile on implants stating that women with breast implants may have a very small but increased risk of developing a tumour in the capsule enclosing the implants BIA-ALCL is a purely T-cell lymphoma arising either in the fluid or fibrous capsule surrounding the breast implant. T-cells are the same immune cells that get attacked by HIV, and they work to get rid of specific foreign materials and are highly important to our immunity. Diagnosis: Most cases are diagnosed during implant revision surgery for a seroma (collection of fluid in the implant pocket)Around 66% of BI-ALCL cases present with seroma after 1 year along with the following symptoms: pain, breast lumps, swelling, or breast asymmetry In the rest of the 33% of BI-ALCL cases, there just appears to be a capsular mass – a tumour of the capsule Risk factors – Research has not conclusively identified risk factors and causal factors, but the following may be associatedThe presence of a bacterial biofilm around the implant – this may cause delayed immune reaction, and excessive division of T-cellsTextured implantsA consequence of capsular contracture or repeated capsular tearsGenetic predispositionAn autoimmune disease Level of RiskIn 1997, approximately 91 cases of BI-ALCL had been reported. As of 2016, a total of 278 cases have been reported around the world. To give you an idea of how rare this is, it is important to know how many women in the world have breast implants. In 2014 alone, 1.3 million women (1,348,197) got breast implants. Since its first report, more than 15 million women may have gotten breast implants.The Netherlands’ nationwide pathology database which holds information on approximately 9 million people with various diseases and conditions found that the incidence rate of BI-ALCL cases per 100,000 women with breast implants was just 0.1 to 0.3 per yearThis means that women with breast implants are 2 times more likely to be struck by an asteroid than develop BI-ALCL.The National Cancer Institute estimates 3 in 100 million women per year in the US are diagnosed with BI-ALCL. Description of previous casesThe mean age of the patients was 52 years (range 28–87 years)The most common length of time between implantation and diagnosis of BI-ALCL was 9 years (range 1-32 years)70% of cases have a malignant fluid collection (seroma) around the fibrous capsule surrounding the implant after 1 or more years30% of cases have a distinct tumour mass of the implant capsule and this may be a more severe form Treatment Individuals are fully cured if caught early with total capsulectomy and mass removal. Please refer back to your surgeon to ask them more about the condition.Hope this helps.
