  Early-stage breast cancer: Genetic testing before surgery may help people make decisions about breast conservation or mastectomy.

• ---

  Metastatic breast cancer: People who test positive for a BRCA1, BRCA2 or PALB2 mutation may qualify for treatment with a PARP inhibitor such as Lynparza (olaparib) or Talzenna (talazoparib). People who test positive for a PTEN mutation may qualify for treatment with the targeted therapy Truqap (capivasertib). Tumor testing may also be required. People who test positive for a mutation may be eligible for treatment with a targeted therapy or participation in a clinical trial.

• ---

  Intermediate-risk or high-risk prostate cancer: People with intermediate-risk or high-risk prostate cancer who test positive for an inherited mutation may qualify for a clinical trial using a targeted therapy.

• ---

  Metastatic castration-sensitive prostate cancer (mCSPC): People who test positive for a mutation in BRCA2 may qualify for treatment with the PARP inhibitor Akeega. People who test positive for a mutation may be eligible for a clinical trial.

• ---

  Metastatic castration-resistant prostate cancer (mCRPC): People who test positive for a mutation in BRCA1, BRCA2 may qualify for treatment with a PARP inhibitor such as Akeega, Lynparza, Rubraca or Talzenna. People who test positive for a mutation in ATM, ATR, CDK12, CHEK2, FANCA, MLH1, MRE11A, NBN, PALB2, RAD51C or RAD51D may qualify for treatment with a PARP inhibitor such as Lynparza or Talzenna. Additional tumor testing may be needed. People who test positive for a mutation may be eligible for a clinical trial.

• ---

  Stage 3 or 4 ovarian, fallopian tube or primary peritoneal cancer: People who test positive for a BRCA1 or BRCA2 mutation may qualify for maintenance therapy with a PARP inhibitor. People who test positive for a mutation in another gene may qualify for treatment with a PARP inhibitor or another targeted therapy. Tumor testing may also be required. People who test positive for a mutation may be eligible for a clinical trial.

• ---

  Advanced pancreatic cancer: People who test positive for a BRCA1, BRCA2 or PALB2 mutation may qualify for maintenance therapy with a PARP inhibitor if their pancreatic cancer didn't get worse for at least 4 months after chemotherapy . People who test positive for a mutation may be eligible for a clinical trial.

• ---

  Advanced cancer with limited treatment options: Genetic test results may help identify additional treatment options, such as targeted therapies approved for other cancers or eligibility for clinical trials.

• ---

  People with colorectal cancer making decisions about surgery: Genetic testing may help people make decisions about undergoing more extensive colectomy surgery to prevent future cancers. Women who test positive for a Lynch syndrome mutation may have the option to undergo hysterectomy (removal of the uterus) and oophorectomy (removal of the ovaries) to lower their risk for gynecologic cancer.

If you are newly diagnosed with cancer or need to make treatment decisions, genetic testing may help inform your decisions. The following questions can help you make a decision about genetic testing and understand how the results may affect your treatment options.

  Step 1: Gather your family health history. Genetic testing is most informative for you and your family if you can gather as much information about the health and history of cancer in your family.

• ---

  Step 2: Speak with a genetics experts. (See the tips in the next section for more details about why and how to find a genetics expert).

• ---

  Step 3: Once your test is ordered, a saliva or blood sample will be sent to the lab for genetic testing.

• ---

  Step 4: You should receive your results in 2-6 weeks. Quicker testing may be available for people who need results sooner in order to make treatment decisions.

• ---

  Step 5: Speak with a genetics expert for post-test counseling. They will explain what your results mean for you and your family and outline your medical options.

Most expert guidelines recommend speaking with a genetics expert before undergoing genetic testing, a process known as genetic counseling. Genetic counseling can reduce the uncertainty about whether you should have testing, which test to order and what the test results mean for you and your family. Below are tips to help you move forward with genetic counseling and testing and determine next steps once you receive your results.

  You had limited genetic testing in the past with a test that only looked for one or a few genes and your results were negative.

• ---

  You had genetic testing before 2014 and your results were negative.
