News and current affairs
Women exposed to higher levels of the pesticide DDT before the age of fourteen have a five times higher chances of developing breast cancer when they reach middle age.
In developed countries, breast cancer affects about one in ten women, and in many of these countries the disease is on the increase.
Both research teams describe how the use of a chemical inhibitor can kill tumor cells that have either a BRCA1 or BRCA2 gene defect causing hereditary breast cancer.
The discovery could also work to prevent hereditary breast cancer cells from growing into tumors.
We have shown that PARP inhibitors are effective at killing BRCA2-defective breast cancer cells, and that the tumors they cause can fully regress and disappear following treatment with a PARP inhibitor.
We are now initiating clinical trials to determine how efficient these PARP inhibitors are in the treatment of metastasized breast tumors.
It is possible that highly metastasized breast tumors might have acquired additional genetic changes causing resistance to treatment with PARP inhibitors.
Therefore, we suggest that PARP inhibitors might be more useful in the prophylactic treatment of women carrying the gene responsible for this form of inherited breast cancer.
Thus, while the use of PARP inhibitors to treat established tumors may be feasible within a few years, we could have to wait at least a decade before a prophylactic treatment for inherited breast cancer is widely available.
One 1989 study showed that women with metastatic breast cancer who attended support groups survived longer, but these results have not been duplicated.
Should a healthy woman diagnosed as susceptible to breast cancer undergo a prophylactic mastectomy?
The commercial stakes are growing as it becomes possible to test for predisposition to common diseases such as breast cancer and heart disease where the potential market is immense.
Breast cancer, the most common life-threatening malignancy in the West, is more curable than ever but remains one of the most common causes of cancer death.
Because progress against breast cancer is incremental - ie, no single treatment is instantly recognized as dramatically superior - big disparities exist in how various treatments are applied in different countries.
NEW YORK - On May 26, Angelina Jolie's aunt, Debbie Martin, died of breast cancer at 61.
In the United States, health insurers cover the cost only if a first-degree relative - for example, a woman's mother - has had a history of breast or ovarian cancer; other women must pay out of pocket.
For Jolie, that means often using her iconic status to advance a positive agenda, whether the issue is Syrian refugees in Jordan or breast-cancer awareness.
TORONTO - Breast-cancer screening has long been viewed as one of the most important tools for reducing mortality from the disease.
That is why recent doubts about its effectiveness - intensified by the publication in February of the 25-year follow-up to the Canadian National Breast Screening Study - have come as such a shock.
How can breast-cancer screening, which facilitates early detection of the disease, not prevent deaths from it?
A mammogram (x-ray of the breast) is administered to ostensibly healthy people to detect unsuspected disease.
The first limitation of breast-cancer screening is obvious: where effective diagnosis and treatment are not available, screening cannot have any impact.
But there is more to the issue - namely, whether screening ultimately fulfills its intended purpose of reducing breast-cancer mortality rates.
More important, none has found a reduction in advanced breast cancer in the screened groups - a requirement to deem screening effective.
Such trials begin with the selection of women at risk of developing breast cancer, and randomly allocate them to be screened or not.
Any woman in either group who develops breast cancer is treated to the fullest extent possible, following the closest possible treatment plan to other participants in the trial (taking into consideration the stage of the disease at diagnosis).
The first was in New York in the 1960s, using annual mammograms and breast examinations for the screened group.
The second, the Canadian National Breast Screening Study, which began in the 1980s, also used annual mammograms and breast examinations for the screened group.
My company, for example, is launching a portfolio of 15 essential medicines to treat diseases including diabetes, respiratory illnesses, and breast cancer.
Successes with screening and treatment of breast, colo-rectal, and cervical cancer have also helped.
One of three young women treated with radiation to the chest to arrest Hodgkin's disease will develop breast cancer by age 32.
Epidemics caused by fat are now manifest: Type 2 diabetes, increased rates of heart and cardiovascular disease, and notably more cancers, such as breast cancer.
For early-stage breast cancer patients, genetic markers show whether chemotherapy is likely to have an impact, or if hormone therapy alone is the better option.
Yet, the death rate from breast cancer is falling in most Western countries even though the number of cases remains relatively unchanged.
Even though science may clearly point to the best way to fight breast cancer, uneven application of new treatments may cause many women to suffer, or even die, unnecessarily.
