700,000 UK women at risk of 'hidden' breast cancer

More than 700,000 women across the UK are living with a "hidden" breast cancer risk because they have "high breast density", according to a health charity.

Breast Cancer Campaign warned women were at a higher risk of developing a tumour if they had more collage and glandular tissue than fatty tissue in their breasts.

Research showed women with the highest density were up to five times more likely to develop breast cancer than those with low density.

Some 8.3% of women aged between 47 to 75 were estimated to have high breast density, according to the clinical trial.

Increase in skirt size 'can increase cancer risk 33%'

A study that has linked an increasing skirt size to breast cancer examined the self-reported "central obesity" of more than 90,000 women across England aged over 50 and who had no known history of breast cancer.

During the research, published in the journal BMJ Open, asked about their skirt size when they were aged 25, their current size and a number of other health questions.

During the three-year follow-up period 1,090 women developed the disease.

The researchers found that a unit increase in UK skirt size every 10 years between 25 and postmenopausal age was linked to a 33% increased risk of breast cancer.

Going up two skirt sizes in the same period was associated with a 77% greater risk, they added.

They also found that a reduction in skirt size decreased the risk of breast cancer but cautioned that three quarters of the women surveyed increased their skirt size during their adult lives.


Thicker waist 'linked to breast cancer'

Overall weight gain leading to an increasing skirt size could increase a woman's risk of breast cancer by as much as 33%, researchers have found.

If a 25-year-old women goes up a size - for instance from a size 12 to a 14 - every 10 years until after they go through the menopause they could be increasing their chances of getting the disease, the study found.

The authors said that overall weight gain has been linked to breast cancer but a thicker waist appears to be particularly harmful.

New radiotherapy 'eliminates need for numerous visits'

An innovative radiotherapy treatment will "eliminate the need for numerous hospital visits" and greatly improve the patient's quality of life, a health chief said.

Professor Carole Longson, director of health technology evaluation at Nice, said:

Unlike regular radiotherapy, with the Intrabeam Radiotherapy System only one dose is required.

This single dose is given at the same time as surgery, eliminating the need for numerous hospital visits.

Regular radiotherapy typically requires numerous doses over a three week period - although some people may receive it for longer - and is performed weeks or months after surgery or chemotherapy.

Whilst current evidence was not extensive, this type of radiotherapy was more convenient for patients and can improve a person's quality of life.

It's still a new treatment - so far only six centres in the UK have used the Intrabeam Radiotherapy System to treat early breast cancer.

'Innovative' radiotherapy for breast cancer sufferers

The National Institute for Health and Care excellence (Nice) gave intrabeam radiotherapy the seal of approval for use on the NHS.

The treatment involves administering a single dose of radiotherapy to patients during surgery.

A single dose of radiotherapy could be "more convenient" for patients, Nice said.

Intrabeam radiotherapy will be available to patients in the early stages of breast cancer.

Antibody reduced tumour size in the mice by 94.8%

In experiments on mice with the same type of HER2 positive breast cancer, scientists used an antibody drug to block activity of alpha v beta 6.

We found that simultaneously targeting alpha v beta 6 and HER2 in mice with tumours grown from human breast cancer cells greatly improved the effectiveness of Herceptin - even eliminating tumours that did not respond to Herceptin alone, which could have the potential to improve treatments for patients with these highly aggressive cancers.

Combining the antibody with the drug Herceptin, which targets the cancer-driving HER2 protein, completely eradicated the animals' tumours after six weeks of treatment. Using the antibody on its own reduced the size of tumours in the mice by 94.8%.

In comparison, treatment with Herceptin alone led to a 77.8% reduction.

Up to 70% of women with HER2-positive breast cancer either do not respond to Herceptin or develop resistance to the drug, leaving up to 7,000 women a year in the UK with limited treatment options.


Scientists find breast cancer tumour growth molecule

Scientists found a molecule that helps tumours in an especially deadly form of breast cancer have grow and spread. The molecule, known as alpha v beta 6, could be used both to identify at-risk patients and develop new treatments, say scientists.

A study found high levels of alpha v beta 6 in 40% of tumours in women with HER2 positive breast cancer, a form of the disease that does not respond to conventional hormone therapy. These patients were twice as likely to die within five years of diagnosis as those with low levels of the molecule.

In experiments on mice with the same type of breast cancer, scientists used an antibody drug to block activity of alpha v beta 6. Combining the antibody with the drug Herceptin, which targets the cancer-driving HER2 protein, completely eradicated the animals' tumours after six weeks of treatment.

Blood test would allow women to 'control cancer risk'

A simple blood test which could detect the early signs of breast cancer would allow a woman to "take control of her own risk", a medical expert said.

Dr Matthew Lam, senior research officer at the charity Breakthrough Breast Cancer, described the findings as "definitely promising".

This could mean that in the future a woman may be able to have a simple blood test to look for this DNA signature, and therefore know if she is at a higher risk of developing breast cancer.

If she does have this signature, she could then work with her doctor to explore the options available to help her take control of her own risk.

These could include lifestyle changes, tailored breast screening, risk-reducing drugs or surgery.

Expert: Breast cancer blood test data 'encouraging'

Data from a study into a potential blood test for breast cancer is "encouraging" as it would make early detection of the disease in all women much easier, a science chief has said.

Lead researcher on the study, Professor Martin Widschwendter, from University College London, said:

We identified an epigenetic signature in women with a mutated BRCA1 gene that was linked to increased cancer risk and lower survival rates.

Surprisingly, we found the same signature in large cohorts of women without the BRCA1 mutation and it was able to predict breast cancer risk several years before diagnosis.

The data is encouraging since it shows the potential of a blood-based epigenetic test to identify breast cancer risk in women without known predisposing genetic mutations.

Breast cancer blood test 'could screen most women'

A blood test for breast cancer could soon be available and offer an early warning system for all women, not just those with the BRCA genes, scientists said.

Experts found a molecular "switch" in blood samples which increase a women's chances of having breast cancer.

The marker is associated with the BRCA1 breast cancer gene but was also found in other breast cancer patients who went on to develop the disease.

Before this blood test there was no way of predicting the likelihood of breast cancer in someone if the disease did not run in their family.

Around 10% of breast cancers are caused by BRCA1 and BRCA2 gene variants inherited from parents, leaving 90% of cases unexplained.
