Radiation Therapy
Breast-Preserving Surgery and Radiation
Therapy of Early Stage Breast Cancer
Radiation treatment of local
tissues of the body, known as radiotherapy, can destroy cancer cells while
producing minimal injury to surrounding tissues. Radiation therapy is most
commonly used in conjunction with a lumpectomy. Radiation to the breast does not
cause hair loss. After a patient has sufficiently healed from a lumpectomy (2
weeks after surgery for many women) radiation treatment will begin. Treatment
usually consists of a few minutes each day, four or five days a week, for
approximately six to seven weeks. Following this, some patients will need a
radiation "boost" to the surgical site. This can be accomplished by
continuing treatment for approximately one to two weeks with external radiation
or temporary placement of radioactive seeds (implants) in the breast at the
biopsy site/lumpectomy.
Radiation Therapy as a Supplement (Adjuvant)
to Mastectomy
Following a mastectomy,
examination of the surgical specimen by the pathologist may show that all of the
cancer cells were not completely removed. Postoperative radiation therapy may be
recommended in this instance, particularly if the cancer is large or if the
cancer has spread beyond the tumor that was removed. Radiation therapy usually
controls cancer cells remaining in these areas. Treatment usually consists of a
few minutes each day, four or five days a week, for approximately six to seven
weeks. Following this regimen, some patients will need a radiation ìboostî to
the surgical site. This can be accomplished by continuing treatment for
approximately one to two weeks with external radiation or temporary placement of
radioactive seeds (implants) in the breast at the biopsy/mastectomy site.
