Is genetic testing needed to assess breast cancer risk?

Hello,

Welcome to icliniq.com.

I am so sorry to hear about your diagnosis, especially given your family history. It is completely normal to feel overwhelmed with all the information coming your way. Let me help break things down as simply as possible and address your concerns.

Given that both your aunt and grandmother had breast cancer, your oncologist is likely suggesting genetic testing to determine if you carry any inherited mutations (such as BRCA1 or BRCA2) that could increase the risk of breast cancer, which could also affect your daughters later in life. Genetic testing is important because it helps assess your risk of cancer recurrence or the development of other cancers, and it can also guide treatment decisions, such as whether you might benefit from targeted treatments like PARP inhibitors (Poly ADP-ribose polymerase inhibitors), While genetic testing can be valuable, it can also be costly if not covered by insurance.

Some cancer centers offer financial assistance, so it may be worth inquiring about. If you test positive for a mutation, your daughters would have a higher risk of developing breast cancer and might consider genetic testing when they are older (typically around 25 to 30 years old). Regarding treatment options, there is often debate between undergoing surgery first or chemotherapy first, as each case is unique. Surgery can involve either a lumpectomy (removing just the tumor and surrounding tissue, often followed by radiation) or a mastectomy (removing the entire breast, especially if the cancer is extensive or has a high risk of recurrence).

On the other hand, neoadjuvant chemotherapy is administered before surgery to shrink the tumor, making it easier to remove. This approach is often used when the tumor is large or if there is concern about potential cancer spread. The decision depends on factors such as tumor size, genetic risks, and whether the cancer has spread, so discussing this thoroughly with your oncologist or seeking a second opinion can be helpful.

It is understandable that your husband is interested in alternative medicine, but the best approach is to combine conventional treatments with complementary therapies like acupuncture, yoga, or nutrition support to help manage side effects and improve quality of life. Alternative treatments alone are generally not recommended for cancer treatment, as they lack proven effectiveness, especially for aggressive diseases. Always consult your oncologist before trying any alternative therapies. As for your daughters, their risk depends on whether you have a genetic mutation. If you test positive for BRCA1 or BRCA2, they would have a 50 percent chance of inheriting the mutation, meaning they may need to start screenings earlier and consider preventive measures. If no mutation is found, their risk would be similar to the general population, which is about 12 to 13 percent (one in eight women).

Moving forward, consider genetic testing if recommended, discuss your treatment options in-depth with your oncologist, and seek a second opinion if needed. You are facing a difficult situation, but staying informed and asking questions will help you make the best decisions for yourself and your family. You have a strong network of doctors and support systems to guide you through this, take it one step at a time.

I hope it helps you.

Thank you.
