(Ivanhoe newswire) -- Breast cancer patients typically must choose
between removing only the breast cancer tissue through lumpectomy or undergoing
a mastectomy and removing the entire breast. Mastectomies do not require
post-surgery radiation therapy, and lessen anxiety for cancer reoccurrence. A
new analysis reveals which factors influence patients' decisions.
Patients' attitudes on surgery and their family and friend's opinions influenced
surgical choices made by women. Patients in all racial and ethnic groups who
were more involved in their treatment decisions were more likely to have a
mastectomy. Patients more concerned about body image and their spouse's opinion
were less likely to have a mastectomy than those less concerned.
The twenty-year risk of local recurrence is significantly lower for mastectomy
patients, according to researchers. The risk for reoccurrence is only three to
five percent for mastectomy patients, compared to 15 to 20 percent after
lumpectomy and radiation.
Researchers studied over 3,000 women diagnosed with breast cancer from June 2005
through February 2007 reported in Los Angeles or Detroit. Primary factors
analyzed include patient involvement with decision-making, race or ethnicity,
concern about reoccurrence, effects of radiation, impact of surgery on body
image, and the role of others in decision making.
