Recent research presented today at EBCC-5 from the million women study found that taking Hormone Replacement Therapy (HRT) increased the risk of some types of breast cancer, but not others.
Scientists analysed the data from the UK study to try and find a link between HRT and the type of breast cancer that developed. The research found that women who took HRT had an increased risk of developing lobular cancer (affecting the cells in the ducts of the milk-producing glands) and tubular cancer. There was not such an increased risk of developing ductal breast cancer, the most common type of breast cancer that affects the cells lining the milk duct. There was no increase in the risk of medullary breast cancer, a kind of cancer that is common in women with a genetic predisposition to breast cancer.
The study demonstrated that women who had taken combined HRT (oestrogen and progesterone) had an even greater risk of developing lobular and tubular breast cancer than women on oestrogen only HRT. The researchers also discovered similar findings for women with breast cancer in situ - when the cancer has not spread to the surrounding tissues in the breast or other parts of the body. Women that took HRT had a significantly greater risk of developing lobular cancer in situ than ductal carcinoma in situ.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
