The study, which was published on the British Medical Journal, revealed that those who consumed more showed a greater risk of alcohol-related cancers. They also said radiation treatment should not be offered as a treatment following a lumpectomy because it “does not affect mortality”.

So, this, because it’s a very good prognosis, we followed the 100,000 women for up to 20 years and we found that, at 20 years, about 3 percent of them had died of breast cancer.
Apart from the surgery versus no surgery question, the team did see clear racial and age differences. Some had developed invasive disease in either breast, but more than 500 deaths were in women never diagnosed with a second tumor or recurrence, meaning their DCIS had likely spread before they received treatment, Narod said.
High risk patients were identified as those diagnosed younger than 40 (which researchers suggested could constitute a different disease), black women and those whose DCIS tests positive for HER2, a protein which can increase the growth of cancerous cells.
To date, the standard of care has been to remove DCIS tissue, even if there is only a tiny bit present, rather than continuing to monitor the cancer for any spreading.
Mammograms that pick up what have been thought of as very early cancers, or DCIS, may in future just lead to lifestyle changes and monitoring. “So the more certainty we can have as patients, the more comfortable we’re going to be”, said Mary Lou Smith, 60, from Chicago.
However some ladies who died of breast most cancers ended up with the illness all through their physique with out ever having it recur of their breast – many, the truth is, had no breast as a result of that they had had a mastectomy.
Women who undergo single or double mastectomies or radiation as treatment for ductal carcinoma in situ, or DCIS, do not appear to be increasing their chances of survival, the paper argues. Today, WCH is a world leader in the health of women and Canada’s leading, academic ambulatory hospital. Until now, the impact of various factors (including age at diagnosis, ethnicity and treatment) on mortality rates has not been studied.
“I think this can help to talk women off the cliff”, Casteel said. She questioned whether those women who were treated and ended up dying of breast cancer anyway had been misdiagnosed.
That type of approach can meet resistance from patients. Some may even take the extreme measure of removing one or both breasts completely. “In comparison with ladies who actually have most cancers, it’s nothing”.
“The guidelines are useful for giving people some indication of where risk starts”. However, the risk was raised for men who had smoked, the researchers found. “To me, my dark gray could be someone else’s black”. It was, she said, a wonderful read. “There have been studies in Europe that say this, but never anything of this magnitude”, she said.
“One clinical implication is to reiterate that DCIS is not an ’emergency, ‘ ” said Sarah Hawley, a cancer research specialist at the University of Michigan in Ann Arbor. “This has happened with the treatment of DCIS”.
Tice added, “This new information will enable women to work with their physicians to implement an optimal screening and risk reduction plan to reduce their chances of breast cancer”.

Evidence also suggests, for example, that previous blanket prohibition of soy protein for breast cancer patients may not be warranted.
