Conservative treatment of breast cancer is now an accepted oncological
procedure. It further allows a good functional and cosmetic result. T

iotherapy and a sometimes difficult follow-up during many years. The c
ontraindications for conservative breast cancer therapy are numerous a

iooncological center by a breast conserving procedure. We have confirm
ed or defined criteria which lead to a good local tumor control as wel
l as to good functional and cosmetic results.
