A Next-Generation Sequencing test that searches for mutations in BRCA1 & BRCA2 genes. BRCA stands for BReast CAncer which is usually classified into Breast cancer Type 1 and Type 2. There are two genes, namely, BRCA1 and BRCA2 which are found in every normal individual. But any genetic variation or mutations occurring in either of these two genes, can lead to the incidence of breast, ovarian, and to a lesser extent other cancers such as prostate cancer, pancreatic cancer, and melanoma. At the moment breast cancer is the most prevalent cancer in Indian women having recently overtaken cervical cancer.
The life time risk for developing Breast/Ovarian Cancer is 12% in a normal individual, whereas if you carry a BRCA mutation your risk increases by 50-85%.
Mutations in the BRCA1 and BRCA2 genes are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase a person's chance of developing cancer. Although breast cancer is more common in women than in men, the mutated gene can be inherited from either the mother or the father. But, not all breast cancers are inherited. These cancers are acquired during a person's lifetime, and they do not cluster in families.
Both male and female have mammary glands. But the difference lies in the fact that, in men, mammary glands are in rudimentary state and are inactive. A lot of familial and sporadic cases of male breast cancers have been reported in the past. Men with mutations in the BRCA1/2 genes have been affected with prostate cancers. In fact, BRCA2 mutations may prove to be a greater cause of cancer in men than had previously been though.
If you are positive for a BRCA mutation, there are several options that include:
It is important to discuss with your Doctor for better understanding.
Genes2Me breast cancer panel screens of BRCA1 and BRCA2 mutations, which helps in identifying the clinically relevant or pathogenic mutations. Screening is performed on a high end platform of Next Generation Sequencing (NGS) technique.
