The process was fairly similar for me. I found the lump, had mammagram and ultrasound. My specialist did the biopsy (to confirm tumor was cancer and also to confirm second area was DCIS) and then recommended mastectomy. I received the pathology results a week after surgery from the surgeon. Then saw medical oncologist and radiation oncologist before further treatment.
Just to be clear on one point, if you were to get cancer in your other breast this would be a totally new separate cancer not a recurrence. The cancer you have now cannot move into the other breast. Once you have had breast cancer there is a slightly increased risk of having a second cancer begin in your other breast.
It is very much a personal choice about whether to have a double mastectomy and depends on many factors. I thought at one stage that I should have had a double but my surgeon was very clear that I needed to begin chemo as soon as possible. Having a second mastectomy increases your chance of complications (infection, etc) and could delay chemo if you need it. Also she said that I may feel differently about it given more time, which is absolutely true.
At this stage I am glad that I did not have the other breast off (I was diagnosed in May last year and finished chemo 51/2 months ago and radiation almost 4 months ago). I have been through a lot and still have about a 20% chance of recurrence. For me at the moment, I am happy to wear a breast form on my mastectomy side and continue to recover through physio and lots of exercise. I am glad I have a 'good side' to sleep on. There is a lot to consider and weigh up before making these decisions. Many people feel that they need to do it for piece of mind. I don't feel that way as my chance of recurrence is much higher than my chance of getting a new cancer in the other breast.
Get lots of information before making your decision. I hope it goes well no matter what you decide. Deanne xxx
