What are the benefits of genetic testing for cancer?

What are the benefits of genetic testing for cancer?

A positive test result provides the person an opportunity to understand and, in some cases, manage their cancer risks. For people who are already diagnosed with a cancer, results of genetic testing may help them make decisions about their treatment and understand their risk for other cancers.

How is genetic testing beneficial?

Genetic testing is useful in many areas of medicine and can change the medical care you or your family member receives. For example, genetic testing can provide a diagnosis for a genetic condition such as Fragile X or information about your risk to develop cancer. There are many different kinds of genetic tests.

How does genetics affect risk of having cancer?

Inherited genetic mutations play a major role in about 5 to 10 percent of all cancers. Researchers have associated mutations in specific genes with more than 50 hereditary cancer syndromes, which are disorders that may predispose individuals to developing certain cancers.

What are cons of genetic testing?

Some disadvantages, or risks, that come from genetic testing can include:

• Testing may increase your stress and anxiety.
• Results in some cases may return inconclusive or uncertain.
• Negative impact on family and personal relationships.
• You might not be eligible if you do not fit certain criteria required for testing.

Which of the following is a disadvantage of genetic screening?

Some disadvantages, or risks, that come from genetic testing can include: Testing may increase anxiety and stress for some individuals. Testing does not eliminate a person’s risk for cancer. Results in some cases may return inconclusive or uncertain.

Are there disadvantages to having genetic testing?

Some disadvantages, or risks, that come from genetic testing can include: Testing may increase your stress and anxiety. Results in some cases may return inconclusive or uncertain. Negative impact on family and personal relationships.

Is genetic testing ethically right?

In a large number of instances, when patients receive the results of genetic tests, they are party to information that directly concerns their biologic relatives as well. This familial quality of genetic information raises ethical quandaries for physicians, particularly related to their duty of confidentiality.

What type of cancer has genetic risk factors?

Some cancers that can be hereditary are:

• Breast cancer.
• Colon cancer.
• Prostate cancer.
• Ovarian cancer.
• Uterine cancer.
• Melanoma (a type of skin cancer)
• Pancreatic cancer.

Which cancers are genetically inherited?

Inherited cancers are those caused by a mutation in a gene that was present in the egg or sperm cell at the time of fertilization. These cancers make up a fraction of common cancers—like breast, colon, and prostate cancer—as well as less common cancers like pancreatic and ovarian cancer.

What is one of the major risks of genetic testing?

Generally genetic tests have little physical risk. Blood and cheek swab tests have almost no risk. However, prenatal testing such as amniocentesis or chorionic villus sampling has a small risk of pregnancy loss (miscarriage). Genetic testing can have emotional, social and financial risks as well.

Can genetic testing help diagnose thyroid cancer?

Genetic testing is available for certain types of cancer and can be used to confirm or rule out a diagnosis. Genetic and molecular testing can also help doctors choose targeted therapies and design a treatment plan. Unfortunately, the final diagnosis of thyroid cancer is not obtained until after the thyroid nodule has been surgically removed.

What is gengenomic test for thyroid cancer?

Genomic Test Helps Identify Thyroid Nodules That Don’t Require Surgery. A new study has found that a test that measures genomic changes in tissue samples taken from the thyroid can help identify which patients likely need diagnostic surgery for thyroid cancer and which do not. When a suspicious small growth or lump (called a nodule)…

Can a biopsy of a thyroid nodule detect cancer?

Biopsy of a thyroid nodule is commonly done to rule out thyroid cancer. The decision to treat with thyroid surgery is straightforward if the biopsy results are positive for thyroid cancer. Similarly, surgery is usually avoided if the biopsy results are benign.

How are molecular markers used to diagnose thyroid nodules?

Molecular markers can be used in thyroid biopsy specimens to either to diagnose cancer or to determine that the nodule is benign. BACKGROUND. Thyroid nodules are very common and are seen in up to 50% of adults. Biopsy of a thyroid nodule is commonly done to rule out thyroid cancer.
