Breast pain issue for one in three female marathon runners

Summary:
One in three female marathon runners is likely to suffer breast pain (mastalgia) during the course of the event, suggests new research.

One in three female marathon runners is likely to suffer breast pain (mastalgia) during the course of the event, suggests research published online in the British Journal of Sports Medicine.

Women with larger cup sizes seem to be more susceptible, but childless women also seem to be more prone, and wearing a sports bra doesn't always help, finds the study, which publishes as London gears up for its annual international marathon April 21.

The authors base their findings on the responses of just under 1300 female competitors passing through the registration zone for last year's marathon in the capital.

The women were asked how much exercise they took, and its intensity -- including participation in marathons -- whether they wore sports bras and/or other support, and if they suffered breast pain.

Almost one in three (32%; 412) of the runners said they experienced breast pain, a proportion that rose with increasing cup size: half of those with a cup size of F or larger complained of pain compared with 1 in 4 of those with an A size cup.

But childless women were also significantly more likely to say they had breast pain than women who had given birth.

Half blamed their breast pain on the menstrual cycle, but almost a third (30%) said it was only sometimes associated with this. And while around 1 in 8 (12%) women said that hormonal factors worsened their breast pain, 1 in 7 said that exercise made their symptoms worse.

Half the women said they experienced breast pain during moderate exercise while almost two thirds (64%) said their breasts were painful during vigorous exercise.

Almost 1 in 10 (8%) described their pain as distressing or excruciating. And 1 in 6 (17%) said their symptoms affected their ability to exercise.

More than a quarter of those with breast pain said they had reduced their exercise intensity as a direct result of their symptoms, while a fifth said breast pain had prompted them to miss a training/exercise session.

The most popular way of relieving symptoms was to wear a sports bra, with 1 in 5 respondents citing this option. But 9 out of 10 of all participants said they wore a sports bra while running.

"[This suggests] that sports bra use is not necessarily perceived as a method to treat mastalgia and that sports bra design and manufacture needs improvement," say the authors.

Around 1 in 8 of those with breast pain opted for painkillers or holding their breasts while running. But almost half (44%) just put up with their symptoms and did nothing to alleviate them, the responses showed.

"The link between exercise and [breast pain] has yet to be established," conclude the authors. "However, this study identified that exercise was the most prevalent factor in mastalgia occurrence, which may have implications for its management," they suggest.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
