British singer Javine Hylton tested positive for the bowel (colorectal) cancer gene (I’m assuming it’s HNPCC) when she was 17. Her grandmother and her uncle died of colon cancer in their 40’s and her mother was also affected. In a promotion for Jeans for Genes Day, she said:
The more awareness and money that […]

The National Institutes of Health Sister Study is enrolling women to study environmental and genetic risk factors for breast cancer. Researchers hope to enroll 50,000 volunteers for the study. Enrollment will continue through September 2007. You can join the Sister Study if:
Your sister, related to you by blood, had breast cancer.
You are between the […]

When Dana Reeves died last month of lung cancer, everyone was quick to point out that she was a non-smoker. If she had a family history of lung cancer, she would have had a 25 percent higher risk of developing cancer than those without a positive family history.
While smoking is the most common cause […]

Commercially available tests for breast cancer genes are missing 17 percent of mutations overall:
12% of BRCA1 and BRCA2 genes
5% of the cell cycle regulator CHEK2 gene
1% of the TP53 gene in families with Li-Fraumeni syndrome
More accurate genetic tests have been developed, but are not yet generally available in the United States. Women at high […]

In the UK, genetic testing for the BRCA1 and BRCA2 breast/ovarian cancer genes is inefficient and incomplete.
Waiting time for appointments can be as long as nine months in two (11%) of the 19 regional genetics centers surveyed by CancerBACUP.
In one-third (32%) of genetics centres there is a more than six month wait. […]

For friends like Cary and Lori who have been struggling with cancer over the past several years, today’s news announcing the establishment of The Cancer Genome Atlas (note: the acronym TCGA are the letters of the DNA code) by the National Cancer Institute and National Human Genome Research Institute is an exciting one.
At […]

Using samples from an international collaboration, Bank on a Cure, researchers have been able to scan gene chips for single nucleotide polymorphisms (SNPs) that may be associated with myeloma. Myeloma aka multiple myeloma affects more than 250,000 people worldwide and is a cancer of blood plasma cells found in multiple areas of the bone marrow.
Bank […]

Broccoli is one of the few vegetables my toddler will eat. Good thing too because broccoli is known to reduce the risk of cancer.
If you’re among the 50 percent of people without an active GSTM1 gene, you may need to compensate by eating more broccoli or by eating “super broccoli” that has higher levels […]
