Breast Cancer Screening (Young Women)

Neil Carmichael Excerpts

Tuesday 30th November 2010 Westminster Hall

[Pat Glass]

I am aware of Wendy and the fantastic work she does; I also know that she is struggling to secure funding. Perhaps the Minister might look at that as a result of today’s debate. I thank my hon. Friend for making that point.

We know that obesity presents a risk, as do hormone replacement therapy and the use of oral contraceptives. In the binge capital of Europe, we are now told that as little as one alcoholic drink per day increases the risk of breast cancer by about 12%.

[Neil Carmichael (Stroud) (Con)]

Breakthrough Breast Cancer, which is an excellent organisation, has rammed home the point that awareness is important and that we should all do all we can to remind women of that. We should make women aware that they need to be aware.

[Pat Glass]

I absolutely agree.

Going back to the risk factors—obesity, HRT, oral contraceptives and alcohol—all of them are likely to affect women under 50 more than women over 50, and yet women under 50 are not routinely offered screening of any kind. About 1.5 million women in the UK are screened for breast cancer each year, and we must congratulate those involved in the routine screening programme on the many lives they save. The previous Government extended the screening programme so that from 2012, all women aged 47 to 73 will be invited for routine screening. That extension will save many more lives, but it will do nothing to help identify breast cancer in younger women.

Concerns have been expressed that wider screening could lead to over-diagnosis, but recent research is showing that the benefits of mammographic screening in terms of lives saved are greater than the harm caused by over-diagnosis. Those same arguments about over-diagnosis were used in the past to argue against extending screening for womb cancer and cervical cancer, but the response to those arguments has always been that it is better to be safe than sorry, and that, in the case of breast cancer screening, between two and two and a half lives are saved for every over-diagnosed case. Despite that, however, women under 50 are not currently offered routine screening.

It is also argued that film mammograms are not as effective for pre-menopausal women as for post-menopausal, as the greater density of breast tissue in pre-menopausal women makes it more difficult to detect problems. That is absolutely right. Screening of women under 50 may not be as effective as screening of women over 50, but it can still be effective, certainly in the absence of any other screening programme.

It is also argued that routine screening of women under 50 is not necessary, because the incidence of breast cancer is lower in that age group. I would say, “Tell that to the hundreds or thousands of young women battling this disease”, who say that any arguments about numbers are outweighed by the increased virulence of the disease in the young.

We are told that, because breast cancer is less common in women under 50, research trials have shown that regular screening of young women does not help to save lives. It is even argued that in other trials, regular mammogram screening is more of a risk than not screening. However, I say to the Minister, “Tell that to the young women currently undergoing chemotherapy”.

It is absolutely clear that mammogram screening is most effective among women who have gone through the menopause, but recent research shows that it can also be effective among those aged 35 to 50 and that, despite all the counter-arguments, there is now increasing evidence that there are significant gains to be made by routine screening of women from the age of 35 upwards.
