Hiyer,
I'm sorry to hear you have these worries, and I know where you mind is going on this. I have a few questions - when they did the scan the other week, was it only the lymph nodes that they highlighted as a problem, was there anything at all they noted in the breast itself ? Was your wife given a manual examination by a consultant, and if so what were their thoughts ? Has your wife been given any antibiotic treatment during these two breast feeding times ? I will try to answer your question as best I can at the end of your post -
Firstly your wife is 29, that would be a very young age and rare to be something sinister causing the lymph nodes to be inflammed. Its not of course unheard of for breast cancer forms to happen in women of this age, but for it to have been there for a couple of years and the only sign be inflammed nodes would be highly irregular. The fact that the radiographer 'didn't know if to biopsy the nodes or not' is a good sign also, as usually if there is any amount of doubt they will go ahead and biopsy. I am also glad that your wife elected to have a biopsy, as this is the only certain way to know if the nodes contain any unsual cells. What is also good to know is that there have been various checks done over the last couple of years, including last week, all of which have not thrown up anything obviously dubious. The vast majority of referrals to the breast clinic, particularly at your wife's age, are for benign reasons which are too numerous to list here. It is possible that there is a latent infection or some other breast change like the blocked duct you mention, brought about in the last couple of years that arises periodically. Biopsy results can take different times depending on how busy the department is and if they have any backlog of work, it can range from a couple of days to two weeks (from my observations) in breast biopsy cases. Its a horrible wait and can make the most hardened of non-HA person jittery, so hang on in there on that front! There are certainly lots of people on here over the last few years who have had biopsies and breast concerns, but every case is of course highly individual and symptoms are so variable that it is kind of wrong to make comparisons. I will say though, that my assertion that 'the vast majority of breast clinic referrals are for benign reasons' is borne out by the results people have had on this forum. I do think that your wife's vigilance is right though, and she has done the right thing to get referral, as although Breast tissue does change throughout a woman's life one need always be aware to raise changes that don't feel 'normal' to a GP.
Should you be worried ? Not at this point, no, as there seems to be no evidence from any medical professional to say that you should be. I will wait for your reply about the questions and then happy to write some more. If you have more indepth queries, either you or your wife, you can visit
www.breastcancercare.org (it is for people who have benign conditions, breast cancers, and are undiagnosed with anything but just concerned). There is an 'ask the nurses' section on the forums that might interest you, and a helpline number.
