Can parents be screened to find out if they carry breast cancer genes?

Yes. Testing should generally start with an affected individual first if there is one available and willing. Once a mutation is identified, any first degree relative (particularly mothers, sisters, and daughters but also males) would have a 50% chance of carrying the same mutation and should be offered testing. At this point site specific testing (read: less expensive) testing can be offered.
Yes. A simple blood test is available to check if someone carries the trait responsible for many forms of the hereditary type of breast cancer. The brca test should only be performed on those at high risk, and only after counseling by a specialist in hereditary diseases. In general, if you have two close relatives with breast or ovarian cancer, especially at an early age, you may qualify.
Yes. They should see a genetic counselor and if appropriate genetic testing can be performed.

Can all breast cancer patients carry the brca genes?

No! Many patients with breast cancer have no genetic predisposition or risk for breast cancer. However, there are several genetic markers which increase the risk of developing breast cancer over a person's lifetime. Read more...
Yes and no. We all have the brca genes in our dna. God (or evolution, your choice) put it there with the purpose of repairing damaged dna, destroying dna that can't be repaired, and other things. When it's mutated (changed) in certain places, it does not work and leads to the development of cancer. Only a small number of breast cancer patients inherit such deleterious or "bad" mutations.

Yes, and no. We all have the genes named brca, but we don't all have mutations in those genes. It's the brca mutations that increase the risk for breast cancer. It turns out that 85% of breast cancers have nothing to do with the brca gene. So most patients with breast cancer do not have a brca1 or brca2 mutation. I hope that answers your question!

What happens during the breast cancer gene test?

Blood test. It is a blood test to look for the rare brca gene to see if there are increased ridks of breast or ovarian cancer. Is only found in 5% of women for increased breast cancer risk. See: http://www.Mayoclinic.Com/health/brca-gene-test/my00322. Read more...

What's your opinion on the "breast cancer gene test"?

BRAC Analysis. As many as 10-15% of breast cancers in the us are believed to be hereditary. These are linked to mutations of a particular group of genes called the brca genes. There is a simple blood test to check to see if someone has a brca mutation. I advise my interested patients to see a genetic counselor to fully understand the ramifications of this test before having it done. Read more...

Gene expression profiling predicts clinical outcome of breast cancer?

We're Getting There. In the past, we used anatomic staging alone (tumor size, lymph node involvement) to guide rx. Gene profiling allows us a completely separate measure of prognosis, and, more importantly, can predict who may or may not benefit from different chemotherapy agents. In the future, we will hopefully be able to tailor our rx to the specific cancer being treated: the elusive personalized medicine. Read more...

Describe microrna gene expression deregulation in human breast cancer?

Can't do in 400. The study of micro-rnas is cutting-edge and extremely arcane and you need to go directly to pubmed or one of the other big ways to access the scientific data. If someone is offering a breast cancer treatment to re-regulate your micro-rna's, call your district attorney. Glad you have an inquiring mind and i wish you luck with your project. Read more...

What is the hereditary breast cancer gene?

BRCA 1 and BRCA 2. Your healthcare provider needs to be aware of your family history to be able to assess risk of certain cancers and to determine if genetic testing is appropriate. Having a brca mutation increases your risk of breast and ovarian cancer. Being aware of your cancer risk allows the opportunity to take action to prevent cancer. Read more...

Hereditary breast cancer gene, what is it?

Wsh I had more space. BRCA 1 and 2 are important genes that have the purpose of repairing damaged DNA and destroying the one that can't be repaired, amongst other things. When they get mutated (or changed) in specific places, they quit working so the damaged DNA is left in there, resulting in the development of cancer. . Read more...

Whats cause and effect of brca1 gene on breast cancer?

Genetic mutation. Genetic mutation in long arm of chromosome 17 in brca 1 , in 13 brca 2, instead of normal protective proteins which control abnormal growth of cell , repair broken down dna, maintain genetic stability, the abnormal proteins fail to protect, and responsible for 40% inherited breast cancers, 80% of breast & ovarian cancers.

Defect in DNA repair. Brca1 is a large protein involved in repairing dna damage. Deficiency in this protein due to mutation of brca1 gene leads to defective repair of damage to dna that leads to uncontrolled proliferation of cells and cancer. Read more...
