A type test that helped prevent cancer
Advances in medicine and technology have significantly improved our ability to diagnose, treat and even prevent certain diseases. Mutations in the BRCA1 and BRCA2 genes, for example, indicate an increased risk of developing breast and ovarian cancer. Early detection of such mutations can prevent cancer, especially in the early stages. Despite this, many people choose not to undergo genetic testing, often because they are afraid of the results.
Such was the case of a young woman named Caitlin Brodnick, whose father had asked to get tested. For years Caitlin ignored his advice. She knew there was a history of cancer in her father's side of the family and was too scared to get tested. When he was 26 years old, Caitlin realized that he could not postpone it any longer. Finally he met with a genetic counselor and began to test itself.
When she arrived results was devastated. Caitlin had tested positive for the BRCA1 mutation. His worst fears realized, she and her genetic counselor began to discuss their next move. As he considered his options, he remembered hearing a story about Angelina Jolie. The actress had undergone elective double mastectomy after testing positive for the BRCA1 mutation.
Caitlin was both encouraged and inspired by the courage Jolie, and decided to follow suit. At the age of 28, Caitlin had a double preventive mastectomy. Then she said it was the best decision I ever made.
Caitlin is just one example of a broader trend in recent years,. genetic testing has become increasingly common among women. overall, BRCA1 and BRCA2 mutations account for nearly 25% of hereditary breast cancer and 15% of all ovarian cancers. Both breast cancers and ovary usually appear at a younger than other types of cancer age, so early detection even more important. The BRCA1 or BRCA2 mutation can be transmitted from one or both parents. A person with a normal copy of the gene is still at risk from the effects of the mutated gene.
While the effects of some genetic variants are well known, many are not. Understanding the effect of a particular genetic mutation is very important in terms of diagnosis and treatment. The combination of specific genetic variations are certain environmental factors cause despite many common diseases. Such interactions have been found to contribute to diabetes, Alzheimer's disease, asthma and various cancers.
genetic makeup of an individual can do more than point to possible hereditary diseases. Our genes may also help predict how an individual will respond to certain drugs and treatments. Children with a certain type of leukemia can be tested in order to determine the ideal dose of chemotherapy. Genetic testing can also be used to determine the correct dose of antidepressants for the treatment of certain mental illnesses.

An innovative genetic testing allows patients with cancer breast to avoid unnecessary chemotherapy. By examining the genetic makeup of a tumor, scientists are able to accurately predict the likelihood of recurrence. This means that many patients with breast cancer do not have to go through chemotherapy after tumor surgically removed. The test could save an estimated 14% of patients with breast cancer from receiving unnecessary postoperative treatments. While chemotherapy undoubtedly saves lives, side effects can be debilitating. Preliminary test results found that 94% of identified patients, their cancer did not return.
Improving the accuracy of genetic testing helps to better understand what causes the disease. years ago, it was thought that the risk of heart disease which is mainly determined by genetics. This belief led those with a history of heart disease to act as they have of developing heart disease inevitably themselves. Continued research has shown that genetics are only one of many factors.
Diet and exercise play a much larger role than previously thought in determining the risk of heart disease. By improving nutritional habits and increased physical activity, individuals can significantly reduce your risk.
Genetic testing has come a long way, and undoubtedly will continue to advance. With each improvement, our understanding of the disease grows. Only when a disease means you can really create an effective treatment. We can only hope that one day healthcare is based on wellness and prevention rather than treatment.
