Survivor since 2013
If there is not a medical reason that precludes lumpectomy, it will come down to your personal decision. For most early stage breast cancer the survival rate of women who have a double mastectomy is not greater than the survival rate of women who have lumpectomy and radiation. In a large long term non-randomized ( women chose their own treatment, treatments were not randomly assigned) study, some groups of women appeared to have a slightly better survival rate with lumpectomy and rads. , especially women over 50 with small estrogen positive tumors. One big exception that I read about recently is treatment for women who smoke. Radiation may not be as effective for women who smoke, and they may have a better outcome with mastectomy.
