Exercise cuts breast cancer risk in young women……………

Researchers find regular leisurely activity reduces probability of developing the disease among the premenopausal
Exercising reduces the risk of breast cancer in younger women by up to 10 per cent, a study has found.
Researchers found that the most active premenopausal women were a tenth less likely to develop breast cancer than the least active.
Breast cancer is more common in women over 50 who have gone through the menopause, but it can often be more aggressive and difficult to treat when it does develop in younger patients.
Around 5,000 women under 45 are diagnosed with breast cancer each year.
During the study, 10,231 women yet to go through the menopause were diagnosed with breast cancer.

‘Small, healthy lifestyle changes’

Experts from the Institute of Cancer Research in London analysed 547,000 women over an average of almost 12 years, tracking their physical activity levels and whether or not they developed breast cancer.
They concluded that leisurely exercise, which included walking or cycling among other sports, at least three times a week outside of work reduced the risk of breast cancer.
It said the most active 10 per cent were a tenth less likely to develop breast cancer than the least active 10 per cent. However, the researchers said there was no notable benefit from spending longer or increasing the intensity of the exercise.
Dr Simon Vincent, director of research, support and influencing at Breast Cancer Now, which funded the study, said: “Breast cancers in younger women tend to be more aggressive and diagnosed at a later stage, so we urgently need to find new ways to prevent people from developing the disease.”
He said that while it was not possible to predict who will get breast cancer, people can take steps to lower their risk.
“This research highlights how vital it is that we support women to start making small, healthy lifestyle changes that can positively impact their health and help lower their risk of breast cancer,” he said.
Previous studies have suggested exercise could reduce the risk of cancer in menopausal women.
There are around 56,000 breast cancer cases diagnosed every year in Great Britain and as many as four in five of these will occur in women aged 50 and over.
The NHS offers free screening for breast cancer every three years for women aged between 50 and 71.
Younger women, who do not get invited for regular checks, can often be diagnosed at a later stage.
The first sign of breast cancer is often a new lump or bump, which should be checked by a doctor. Other symptoms can include a change in size or shape of one or both breasts, a discharge of fluid from either of your nipples, or a lump or swelling in either of your armpits.
While it is not fully understood why exercise could reduce breast cancer risk, other research has found physical activity can lower sex hormones such as oestrogen and testosterone, which have been linked to increased risk of breast cancer.
Researchers also hypothesised that the risk may also be reduced because exercise lowers the levels of insulin and growth hormones that encourage breast cancer to develop, as well as reducing general inflammation.
The study, published in the Journal of Clinical Oncology, took into account other risk factors for breast cancer, including body mass index, family history and lifestyle behaviours like smoking and alcohol use.
Dr Michael Jones, senior staff scientist at The Institute of Cancer Research, said: “This new research provides us with solid evidence that greater leisure time physical activity is associated with lower risk of breast cancer in younger women.
“It’s important to remember that breast cancer risk is influenced by several factors – including genetics, lifestyle and environment, and many of these are out of our control,” he said. “We still need to better understand the biology behind the link between physical activity and reduced breast cancer risk.”
