August 20, 2010 | Air travel safe for breast cancer survivors: Study | Washington: Women who have survived breast cancer can fly without any worries, says a new study. University of Alberta researcher Margie McNeely said that the theory that breast cancer survivors are at a risk of lymphedema, is outdated. Women have often been warned that post breast cancer,
pressure changes in an airplane cabin could trigger lymphedema, chronic swelling
in the arm. However, McNeely said that the risk is for those women who have had
lymph nodes removed from the armpit, a common procedure during cancer treatment.
When there is the potential for chronic swelling, these lymph nodes work to drain
the fluid. McNeely and Australian researcher Sharon Kilbreath compared two such
groups of patients - one that had had their lymph nodes removed and one that had
not. All the women were breast cancer survivors. Findings indicated that 95 per
cent of the women had no arm swelling. Four women had a slight increase but at
a follow-up test, done six weeks later three were back to normal and only one
woman was found at possible risk for chronic swelling. McNeely said that this
research shows that while there is a risk of developing lymphedema during flight,
that risk is very low. |
