Breast Cancer & Implants: Surgery Options
Breast-Conserving Surgery an Option for Women With Breast Implants and Breast Cancer

May 2, 2008 (New York) -- There's reassuring news for women with breast
implants who develop breast cancer.
Despite earlier concerns, many can be effectively treated with
breast-conserving treatment rather than a more disfiguring mastectomy to remove
the entire affected breast, researchers say.
Breast-conserving treatment consists of surgical removal of the cancerous
area of the breast, followed by radiation to kill any lingering tumor
Breast augmentation is the most common cosmetic procedure in the U.S., with
329,000 implants performed in 2006.
"As these women age, their rate of breast cancer can be expected to rise
as it does for all women. But relatively little research has focused on how
implants affect breast cancer treatment," says Barbara Pockaj, MD, a breast
surgeon at the Mayo Clinic in Rochester, Minn.
Pockaj presented the findings at the American Society of Breast Surgeons
Ninth Annual Meeting.
Implants Don't Affect Recurrence Rates
The researchers examined the management of breast cancer in 71 women who got
breast implants between 1995 and 2006. About half underwent mastectomy,
and the rest received breast-conserving treatment.
The recommendation that a woman get a mastectomy was based primarily on
whether she had a large tumor or several tumors throughout the breast, the same
criteria used for women without implants.
The rate of local recurrence -- cancer returning in the same breast -- was
about 8% in women who underwent mastectomy and those who underwent
That's also in the same range as the local recurrence rate for women without
implants who undergo breast-conserving therapy, Kristin Brill, MD, a breast
surgeon at Kimmel Cancer Center in Philadelphia, tells WebMD. She was not
involved with the work.
Among other findings:
Sentinel node biopsy was accurate in women with implants who had the biopsy,
regardless of what treatment they received. Sentinel lymph node biopsy involves
removing just a few key lymph nodes first, rather than the usual 10 to 20, to
check for cancer spread.
"There were a lot of concerns that implants would affect the accuracy of
the test, but that was not the case," Pockaj tells WebMD.
There was an increased rate of capsular contraction in women with implants
who had breast-conserving treatment: 31% vs. 12% of those who had a
Capsular contraction is one of the most common problems associated with
implants. It occurs when scar tissue forms around the implant, and it can cause
hardening of the breast tissue, rippling in the skin of the breast, and changes
in the shape of the breast. Surgery is sometimes needed to remove the scar
tissue or replace the implant.
Pockaj says that taken together, the findings show "breast-conserving
treatment is a viable option for women with implants. Women are often told they
have to have a mastectomy, but this study shows they don't."
