Research Finds Basal-Like Breast Cancer Does Not Originate from Basal Stem Cells
A case of mistaken identity that may have a significant impact on future breast cancer prevention and treatment strategies has been uncovered in new research.
The study, published by Cell Press in the September 3rd issue of the journal ICell Stem Cell, /Isuggests that despite their "stem cell-like" characteristics, most aggressive breast tumors are not derived from normal mammary gland stem cells.
The glandular tissue of the breast contains two main cell types, outer "basal" cells and inner "luminal" cells....
Eating Fat-rich Diet During Puberty Can Cause Breast Cancer
Eating a high-fat diet during puberty is associated with a greater risk of breast cancer later in life, according to a preliminary research.
The findings come from research at Michigan State University's Breast Cancer and the Environment Research Center.
Physiology professor Sandra Haslam, director of the center, and Richard Schwartz, microbiology professor and associate dean in the College of Natural Science, are now expanding that research.
"The pubertal time period is crucial, as ...
Nuclear Imaging Technologies Leads to Higher Breast Cancer Risk
Nuclear-based breast imaging tests could increase the risk of radiation-induced cancer, reports a new study.
However, the radiation dose and risk from mammography are very low.
"A single breast-specific gamma imaging (BSGI) or positron emission mammography (PEM) examination carries a lifetime risk of inducing fatal cancer greater than or comparable to a lifetime of annual screening mammography starting at age 40," said the study's author, R. Edward Hendrick, clinical professor of radiology ...
The Manner in Which Nicotine Promotes Addiction , Breast Cancer
Nicotine attaches itself to a specific receptor in the body and increases the tendency of nicotine addiction as well as breast cancer, a new study has revealed.
Yuan-Soon Ho of the Taipei Medical University, and colleagues found that human breast cancer cells consistently over-expressed the alpha 9 subunit of the nAChR (nicotinic acetylcholine receptor).
The expression was higher in advanced-stage breast cancer compared with early-stage cancer.
They also ...
Breast Cancer Risk Doubles With a Drink a Day
The risk of breast cancer increases two fold in women who have only one alcoholic drink a day, compared to those who abstain completely, reports a new US study.
To understand how alcohol may influence sub-types of breast cancer, Christopher I. Li, and colleagues at Fred Hutchinson Cancer Research Center conducted an observational study of a subset of patients in the Women's Health Initiative (WHI) study, conducted between 1993 and 1998, which included 87,724 postmenopausal women aged 50-79 years....
Air Travel Poses No Risk For Breast Cancer Survivors: Study
Women who have survived breast cancer can fly without any worries, says a new study.
University of Alberta researcher Margie McNeely said that the theory that breast cancer survivors are at a risk of lymphedema, is outdated.
Women have often been warned that post breast cancer, pressure changes in an airplane cabin could trigger lymphedema, chronic swelling in the arm.
However, McNeely said that the risk is for those women who have had lymph nodes removed from the armpit, a common procedure during cancer treatment....
Cause of Breast Cancer Identified by Indian-origin Scientist
The trigger that sets off a chain of reactions brought together by a cancer-causing gene has been identified by a team of researchers led by an Indian-origin scientist.
The gene has been identified as Wnt1, and may help explain why increased levels of a protein called MTA1 (metastasis-associated protein 1) are oncogenic in certain types of breast cancer.
Wnt pathways govern normal processes like embryonic development and the communication between cells in healthy people.
But for reasons ...
Recovery in Breast Cancer Survivors Boosted by Yoga
New specialized Iyengar yoga program for breast cancer survivors and those undergoing breast cancer treatment affects the recovery positively, new research has indicated.
For two years groups of study participants were asked to fill out a questionnaire about their physical and mental health at the beginning of a 10-week session of Iyengar yoga and again at the end.
After analyzing the data that was collected, Amy Speed-Andrews of University of Alberta found that after the yoga 94 per cent ...
Boffins Identify Genes Linked to Aggressive Breast Cancer
For the first time, scientists have identified 12 genes that could be associated with aggressive breast tumours.
Researchers at the University of Gothenburg, Sweden, say their discovery could result in more reliable prognoses and better treatment strategies for patients.
The results are based on analyses of breast tumours from 97 female breast cancer patients. Half of these patients died within eight years of diagnosis, while the remainder survived for more than eight years.
Breast ...
Outrage After Error in Screening Breast Cancer
An error in the breast cancer screening service was found in a hospital in the Carlisle after it was revealed that eight women were given all clear only to be brought back to the hospital for treatment. More than 1600 women have taken test at the Cumberland Infirmary in Carlisle since April 2007 with 130 of them being recalled to undergo the test for a second time. So far over 49 women have taken the test for a second time with eight of them testing positive for breast cancer with experts suggesting that the number would rise further....
Breast Cancer Risk is Not the Same Among Different Progestins Employed in HRT
Researchers found different outcomes on the advancement of breast cancer on comparing four types of progestins used in hormone replacement therapies.
Progestins are used in hormone replacement therapies to counteract the negative effects of estrogen on the uterus and reduce the risk of uterine cancer. However, evidence in recent studies and clinical trials has demonstrated that progestins increase the risk of breast cancer.
But it is now that theUniversity of Missouri researchers have come to the above conclusion....
New Drug Holds Promise Against Ovarian, Breast Cancer
An international consortium of researchers has shown that an investigational drug, Olaparib, can reduce the size of tumors in women with advanced hereditary ovarian cancer with BRCA gene mutations.
The Phase II ovarian cancer study results - as well as another Phase II trial in which Cedars-Sinai researchers also participated that evaluated the drug's effectiveness in the treatment of hereditary breast cancer - were published in a recent issue of Lancet.
The two trials showed similar levels ...
Britain Sees Drop in Breast Cancer Deaths Over Last Two Decades
Breast cancer deaths dropped by more than 20 percent across 15 European countries over the last two decades, with a fall of nearly a third in Britain, according to a study published Thursday.
At the same time, the level of breast cancer mortality in eastern Europe was described as "catastrophic".
The review of 30 countries, overseen by French researchers, found large decreases in the number of women dying from breast cancer, particularly in Britain and Iceland.
Mortality rates across ...
The First Opponent Navratilova Feared was Breast Cancer
After seven months of treatment and being given the all clear, tennis legend Martina Navratilova has said breast cancer was the first opponent she feared might beat her.
At the start of the year, the nine-times Wimbledon champ said she was devastated on being diagnosed with breast cancer. But now, after seven months' treatment, she said she's beaten it," The Mirror reports.
"The worst part was the first day. I was alone. I had no one to lean on. But the response was great and I know I've ...
Western Lifestyle Blamed for Soaring Breast Cancer Cases in Britain
Western lifestyle that encourages women to over-eat, drink too much and exercise too little is responsible for high number of breast cancer cases, say new figures.
According to data from the International Agency for Research on Cancer, the breast cancer rate in Britain is more than four times higher than in eastern Africa, which has the lowest in the world, reports the Daily Mail.
Other parts of the world also have far fewer cases of breast cancer, with rates only half as high in South America and two-thirds lower in parts of Asia....
