On the other hand it has also been shown that the risk of developing LRR is rising up to 15% or more for women in the presence of two or more adverse factors even though there is no lymph node involvement. In this study, PMRT indications were evaluated in 12 centers, overall Turkey to observe and document the decision making after mastectomy.eninfo:eu-repo/semantics/openAccessConference Object127Supplement: 1S696S69710.1016/S0167-8140(18)31572-XQ1
