Cancer Calculator helps predict risks


After the invention of a new calculator, Women can decide to go to their practitioners before deciding whether to get screened for breast cancer or not. UK scientists have worked out a way to assess women’s chances of developing the disease on the basis of both genetic data and lifestyle risks. They hope to offer a reasonably good prediction by combining information on family history and genetics with other factors such as weight, age at menopause, alcohol consumption etc. Many lifestyle risk factors for breast cancer are known, but each one individually often does not add up to much.

The cumulative effect, however, is much more significant. The same applies to genes. Two inherited genes – BRCA1 and BRCA2 – give women an increased chance of breast cancer. But there are many other genes that are now thought to play a small part. The researchers, for their risk assessment, have taken into account 300 different genes that could be identified. Researchers at the University of Cambridge, have stated that This is the first time that anyone has combined so many elements into one breast cancer prediction tool. It could be a game-changer for breast cancer because now we can identify large numbers of women with different levels of risk.

The researchers, who have published a paper in the journal Genetics in Medicine, have been hoping that a few GP practices would try out the risk assessment tool later this year. A large proportion of the 55,000 breast cancer cases diagnosed each year in Britain’s National Health Service have been in women at increased risk of the disease. If the calculator works well, it could lead to more of those at risk being identified early, when they could be successfully treated. It would also mean that breast-cancer screening, through mammograms, could be more accurately targeted. At present, not all women want to be screened because of the risk of being wrongly diagnosed with cancer. The calculator may help them make a more informed decision.
