LCIS and mastitis?

I have LCIS and DCIS and was wondering if LCIS predisposes you to frequent mastitis when breast feeding by clogging up lobules and ducts.

    I don't know, but the LCIS doesn't clog up the ducts.

    I do have classic LCIS with 'pagetoid spread to the ducts' (pagetoid meaning something like cells are lined up like soldiers, which is common, http://surgpathcriteria.stanford.edu/breast/lcis/printable.html). I don't know if my ducts are clogged too, or, if they were, if that would hinder breast feeding (if I was young enough to do that.)

    But I can't find papers that talk about a connection between LCIS and mastitis, besides this one paper that found 1 case out of 48  cases of ductal enlargement was mastitis and 1 case out of ?88 of ductal enlargement was LCIS.  http://www.ncbi.nlm.nih.gov/pubmed/?term=LCIS+++mastitis.  Usually LCIS is not symptomatic; its usually (but not always) found as an incidental finding when they do a biopsy for something else.

    I had mastitis both times I was pregnant (many years ago! kids are 23 and 26), but never  in the almost 10 years since my diagnosis of LCIS.  Mastitis is a very common condition during breastfeeding; LCIS is a very uncommon condition, actually rather rare, generally found in women who are in their 40's or 50's.

    Hi anne,

    Why do you say LCIS is a rare condition?  I'm in my 60's, and maybe for my age group it's rare, otherwise I don't think so.  It seems a lot of women have this.

    It is estimated that it affects .5 to 3.8% of women. It just seems common here because it is a breast cancer board.

    I agree with Anne.  This website (2013) opines:

    The incidence of LCIS has doubled over the past 25 years and is now 2.8 per 100,000 women. In the past, the peak incidence of LCIS was in women in their 40s. Over the past 3 decades, the peak incidence has increased to individuals in their 50s. The incidence of LCIS decreases in women who are in their 60s to 80s.  http://www.cancernetwork.com/cancer-management/stages-0-I-breast/article/10165/1802570

    In this older study that looked at LCIS women between 1988 -2001, the mean age at diagnosis was 54.3 years.  http://onlinelibrary.wiley.com/doi/10.1002/cncr.21864/full

    I am sure that there aren't too many studies looking at mastitis and LCIS just based on the fact that not many lactating women have been diagnosed with LCIS. I had kids late in life so I also breastfed in my late 30s. I was thinking about the pathophysiology of why I had so many problems with mastitis and wondered if LCIS may have played a role.

    Thanks for the responses ladies.
