To review:
Whether one should get tested for BRCA1 and BRCA2 as a blood test is available easily.
Introduction:
Breast cancer refers to the disease of cancer, which primarily affects the breasts of the individual, mostly females. This cancer can be genetic and BRCA genes are breast cancer genes. They are called so because mutations in these genes can cause breast cancers in both females and males. They can be passed down to the child from either parent.
Explanation of Solution
There are genetic tests available to find out if the BRCA gene in an individual is mutated or not, but genetic testing is recommended to those people with high risks of developing breast cancer. For example, if a person has a family history of breast cancer, ovarian cancer or a family member with a mutated BRCA gene.
Due to the cost and time consumption, this test is not recommended to every individual who is experiencing breast cancer. This test is not recommended otherwise because there are only slight chances that a family member is a carrier of this gene mutation. Moreover, emotionally such tests impact severely and may hamper the psychosocial life of the individual and their family members.
Thus, it can be concluded that genetic tests are expensive and impact the person emotionally. They are only recommended to people who have a family history of breast cancer.
