Cancer Genetic Testing
Prenatal testing for genetic problems may be done before or after conception. Testing for spina bifida or Down syndrome is done after a pregnancy is established. Besides the couples listed above, counseling and diagnosis are also recommended for mothers over the age of 35, and those who have received abnormal screening test results, such as alpha-fetoprotein (AFP). For more information about the alpha-fetoprotein test, and when and why you might have it, see alpha-fetoprotein. For those who may be at risk, genetic counseling and prenatal diagnosis are used to help ...Read more

Mom got ovarian cancer at 37. None of her other family got it or any other cancer. Should I consider genetic testing? How do I lower my risk?
No: While genetic testing has value in certain malignancies pointing out who is succeptible and requires careful evaluation such as in breast cancer and congenital polyposis as well as the Lynch Syndrome, ovarian adenoma ca has no major impact from congenital abnormalities. A periodic pelvic sonogram or digital pelvic exam yearly or bi yearly may be helpful ...Read more
I'm a 34 yr old female. My 63 y/o mother has colon cancer. Should i seek genetic testing? What are the pros/cons re: the genetic testing for me?
Knowledge is Power: The brca test is a simple (tho, very expensive) blood test to determine if one carries the risk of developing the hereditary form of breast (& ovarian) cancer. Affected people have a 50%chance of passing this on to their children. If the test is (-), this can be very reassuring; if (+), one may choose to be proactive and undergo prophylactic (preventive) mastectomies and oophorectomies. ...Read moreSee 2 more doctor answers

Very if BRCA mutated: The genes brca1 and brca2 cause breast-ovarian cancer, suspected when women have onset of breast cancer before menopause or when there are several cases of breast/ovarian cancer in a family. Women with a brca mutation have as much as a 50% lifetime risk for ovarian cancer (85% for breast) and often choose prophylactic oophorectomy after positive brca testing since there is no good clinical screen. ...Read moreSee 1 more doctor answer

How do you get genetic testing for cancer? Every family member older then me ie parents aunts and uncles have all died with cancer and now younger bro
Its more complicated: Currently,more than 1% of all human genes are implicated via mutation in cancer.Many people think that the risk of Ca is always passed on through families as a single "cancer gene".However,like other complex diseases, changes in many genes that each play a role in the development of cancer are much more likely to be the cause of familial cancer than a change in a single gene.So,see a geneticist ...Read more

Possibly: Two family members with ovarian cancer is not that common. There are a few inherited conditions that increase ovarian cancer risk. I would suggest that you gather all family info you can get hold of (all family with or without cancer) and visit with your gyn or family doc. They will decide of you need to be seen by a specialist in hereditary cancer. ...Read moreSee 1 more doctor answer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
