DCIS - If it is not cancer than why I am so worried?
My sister had BC at age 45 so I have been going to regular mammograms and ultrasounds. Since having my first mammogram at 40, it was noted that I have very complex breast tissue with fibro adenomas, papillary lesions, chronic cysts etc. Biopsies had revealed atypical cells and have had two previous lumps removed that turned out to be benign.
Now aged 44, I have recently attended my usual round of checkups where some new calcifications were noted. This time some new calcifications were noted at the mammogram, but nothing showed on the ultrasound. I was asked to return the next day for some biopsies. Eight core biopsies were taken and then there was an anxious 5 day wait for results. I met with the doctor on Tuesday and had a lumpectomy the next day. The pathology had shown High Grade DCIS. After yet another wait of 5 days, the results came back a few days ago. Whilst no invasive cancer was found there wasn't a clear margin meaning that the DCIS >3cm. More surgery is recommended to remove further tissue and more pathology. Following the lumpectomy radiation is recommended.
Radiation treatment is not available where I live and this would involve having to leave my family of 4 children (8, 14, 15 & 17) whilst I relocate to Brisbane (4 hours away) for 5+ weeks. (This would also mean I have to stop working for a while). My dilemma is that if at some stage I have a recurrence and require a mastectomy my options would be more limited for reconstruction. Apparently patients who have undergone radiation do not make good candidates for silicone implants. Three years ago I had major surgery to remove a large colon cancer, so using my stomach tissue is out of the question. I have heard of many back problems associated with taking tissue from the back.
My doctor and hubby are not keen on a mastectomy, but I don't like the idea of being away from home for 5 weeks and still living with 6 monthly tests and very limited reconstruction options if needed later. I am also not sure about how health funds and Medicare would contribute to an elected mastectomy. The doctor agreed that a special MRI in Brisbane might give more indication of the extent of the tumour and identify any invasion. Unfortunately, this is not covered by Medicare unless you have 3 blood relatives who have had breast or ovarian cancer. I have decided to pay the fee >$500 but now have to wait until the right day in my cycle. (More waiting).
Can a lumpectomy with positive margins expose previously “protected” DCIS cancer cells to breast tissue and therefore promote invasive cancer?” My grade 3 DCIS is apparently the most aggressive.
Whilst I am feeling very anxious, many online documents state that DCIS is not classified as cancer... so I am not sure why I am so concerned.
It is great to keep busy at work during the day, but I am struggling to get much sleep at night.
Any thoughts/ideas and comments would be great.
