🧬 BRCA gene mutations: Different detection methods
🔍 There are two types of mutations:
Somatic: occur in non-reproductive cells and are not transmitted to offspring. They appear immediately in the body where they originate.
Generative: mutations of germ cells are inherited and appear in the next generation.
🔬 How mutations are detected:
Generative: most often through blood or saliva tests.
Somatic: determined by biopsy of the tumor or metastases. The quality and shelf life of the material are important.
👩⚕️ Important Application:
Based on generative mutations of BRCA 1 and 2, a decision is made on the use of PARP inhibitors for the treatment of breast cancer.
Testing is recommended for women with a family history of breast or ovarian cancer.
🌟 Angelina Jolie effect:
Surgeries to remove the breasts and ovaries can reduce the risk of breast cancer by 97% and ovarian cancer by 95% when the mutation is detected.
It is important to carefully weigh the indications for surgery, taking into account individual risks and possible side effects.
Making a decision about surgical intervention requires an integrated approach, especially in young women, taking into account possible consequences, such as artificial menopause, osteoporosis, and cardiovascular complications.
