BRCA1 Gene News and Research

RSS

BRCA1 is a gene on chromosome 17 that normally helps to suppress cell growth. A person who inherits certain mutations (changes) in a BRCA1 gene has a higher risk of getting breast, ovarian, prostate, and other types of cancer.

X-rays increase breast cancer risk

According to new research X-rays may significantly increase the risk of breast cancer in women who are genetically susceptible to the disease.

Two year wait for breast cancer test results drives women to consider radical surgery

Women in the UK being put under added stress because they are experiencing delays of two years or more for test results to see if they carry a gene associated with an increased likelihood of breast cancer.

New genetic clue discovered about breast cancer

New research has discovered that women in Iceland with a particular gene that raises the risk of breast cancer were virtually certain to develop the disease if they also had a mutation in another gene.

Prophylactic surgery reduces the incidence of ovarian and related cancers

A new multicenter study is the first to suggest that the prophylactic removal of the ovaries and fallopian tubes may provide a different benefit for women who carry a genetic mutation in the BRCA2 gene than for those who have a BRCA1 genetic mutation.

Hormonal treatments reduce risk of cancer returning

Women diagnosed with breast cancer who carry a certain genetic mutation can have breast-sparing surgery but should consider hormonal treatments to reduce their risk of cancer returning.

MRI cost-effective for some women at high-risk of breast cancer

A computer model simulation suggests that adding breast MRI screening may be cost-effective for women of certain ages who carry BRCA1 and BRCA2 gene mutations.

Extension of embryo screening will help reduce serious illness

A fertility watchdog in Britain, the Human Fertilisation and Embryology Authority (HFEA), has given approval for the extension of embryo screening to cover a wider range of mutated genes, in the main those which raise the risk of cancer in later life.

New approach to treating breast cancer uses existing chemo drug

British scientists say women who develop breast cancer because of two common genetic mutations could have their treatment transformed by a chemotherapy drug which already exists.

New information about the molecular pathway used by ubiquitin

Because ubiquitin plays a key role in cell survival, scientists have already begun to develop drugs to target parts of the ubiquitin pathway in treating diseases such as cancer.

Remaining 80% of breast cancer genes may soon be discovered

We are closer to finding the missing 80% of breast cancer genes than ever before thanks to the success of the COSMIC database (Catalogue Of Somatic Mutations In Cancer) the 5th European Breast Cancer Conference (EBCC-5) was told today.

Adjuvant hormonal therapy reduces contralateral breast cancer risk

The risk for a new cancer in the unaffected breast substantially increases in women diagnosed with unilateral, hereditary (non-BRCA) breast cancer, according to a new study.

New insight into pathogenic mechanisms underlying basal-like breast cancers

Basal-like breast cancers (BLC) are highly aggressive tumors with a relatively poor prognosis that account for approximately 15% of sporadic human breast cancer.

Broccoli, cauliflower and cabbage help repair damaged DNA

Need another reason to eat your vegetables? New research shows that some of them contain chemicals that appear to enhance DNA repair in cells, which could lead to protection against cancer development, say Georgetown University Medical Center researchers.

Non-BRCA1/2 hereditary breast cancer linked to new cancers

The risk for a new cancer in the unaffected breast substantially increases in women diagnosed with unilateral, hereditary (non-BRCA1/2) breast cancer, according to a new study by researchers working at Karolinska Institutet in Stockholm, Sweden.

BRCA1 gene inhibits estrogen and progesterone

It's been known that the breast cancer susceptibility gene BRCA1 regulates use of estrogen in breast and other cells, but now researchers at Georgetown University Medical Center have discovered that it also controls activity of a second sex steroid hormone, progesterone.

A good year for breast cancer detection and treatment

It was a good year in women’s health, notably breast cancer treatment and detection. The December issue of Mayo Clinic Women’s HealthSource hails these important advances of 2005.

Breast cancer survival rate boosted by radiotherapy

According to a new study breast cancer patients who have radiotherapy after breast-conserving surgery have a lower risk of a recurrence of the disease and a better chance of beating the illness.

Gene mapping project promises new targeted cancer therapies

Government researchers in the United States have this week launched a pilot project to find all the little genetic changes that cause cancer in the hope it will lead to a whole new world of targeted cancer therapy.

Women satisfied with contralateral prophylactic mastectomy

Mayo Clinic researchers report that most women who have a contralateral (opposite to cancerous breast) prophylactic mastectomy (CPM) are satisfied and would elect this procedure again. Satisfaction with CPM was studied an average of 10 years after the procedure was done. The findings were published online Oct. 3 in the Journal of Clinical Oncology.

Access to genetic counseling and testing are an important part of cancer control

Ten years after the identification of the first breast cancer susceptibility genes so few high-risk minority women have received genetic counseling or testing that the standard methods of calculating risk have not been validated in these groups and the results of genetic testing can still produce surprises.
