SelectedGenetic Breast& Ovarian Cancer Risk | London Blood Tests |
At London Blood Tests, we provide advanced genetic testing services to help you understand and manage your health risks. Our Genetic Breast & Ovarian Cancer Risk Test screens for genetic variants associated with an increased risk of breast and ovarian cancer. This test provides valuable insights into your genetic predisposition, allowing you to take proactive measures in managing your health.
Our Genetic Breast & Ovarian Cancer Risk Test screens and detects genetic variants in 8 genes that may increase the risk of breast and ovarian cancer. The genes analyzed include ATM, BRCA1, BRCA2, CDH1, CHEK2, PALB2, PTEN, and TP53.
1. ATM: Involved in DNA repair. Mutations increase the risk of breast cancer and other cancers.
2. BRCA1: Helps repair damaged DNA. Mutations greatly increase the risk of breast and ovarian cancer.
3. BRCA2: Similar to BRCA1, involved in DNA repair. Mutations also significantly increase the risk of breast and ovarian cancer.
4. CDH1: Encodes a protein that helps cells stick together. Mutations are linked to an increased risk of hereditary diffuse gastric cancer and lobular breast cancer.
5. CHEK2: Encodes a protein involved in DNA damage response. Mutations can increase the risk of breast cancer and other types of cancer.
6. PALB2: Works with BRCA2 in DNA repair. Mutations increase the risk of breast cancer.
7. PTEN: A tumor suppressor gene that regulates cell growth. Mutations cause Cowden syndrome, which increases the risk of breast, thyroid, and other cancers.
8. TP53: Encodes the p53 protein, a key tumor suppressor that prevents cancer. Mutations are associated with Li-Fraumeni syndrome, which greatly increases the risk of various cancers, including breast cancer.
• Individuals diagnosed with breast or ovarian cancer.
• Those with a family history of breast or ovarian cancer.
• Anyone seeking to understand their genetic risk for breast and ovarian cancer.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
