Has anyone had any metastasis from DCIS some months or years down the line?
I have read in various medical journals over the past few months that a mastectomy for DCIS strangely and seemingly inexplicably has a slightly higher mortality rate due to breast cancer than just receiving a lumpectomy + radiotherapy for DCIS. Preventing a recurrence of DCIS and/or an invasive breast cancer does not seem to prevent death from breast cancer, and as said, death from breast cancer has a slightly higher rate after a mastectomy than after a lumpectomy + radiotherapy.
It seems, according to research, that breast cancer does not spread in a predictable sequence by stage as assumed in past decades i.e. out of duct wall, within and throughout breast, infiltrating lymph nodes and then out to distant organs, but instead it can sometimes mysteriously spread in other ways not really known or understood by medics or scientists at this time. Research papers advise early chemotherapy for DCIS because of these findings published in 2018.
Has anyone had any experience of these issues? Have you received chemotherapy straight off for DCIS despite no sign of invasion or microinvasion just to be on the safe side? Are any oncologists taking this route out of an abundance of caution? Have you had spread without recurrence of DCIS or a recurrence of invasive breast cancer?
