PROCEDURE
AGE TO BEGIN
FREQUENCY
Female Breast
Breast awareness - Women should be familiar with their breasts and promptly report changes to their healthcare provider. Periodic, consistent breast self-examination (BSE) may facilitate breast awareness.
18 years
N/A
Clinical breast examination
25 years
Every 6 to 12 months
Breast MRI with contrast
25 years, or individualized to a younger age if a relative has been diagnosed younger than age 30.
Annually
Mammography
30 years. If MRI unavailable, start at 25 years, or individualized to a younger age if a relative has been diagnosed younger than age 30.
Annually
Consider risk-reducing mastectomy.
Individualized
N/A
Consider options for breast cancer risk-reduction agents (i.e. tamoxifen).
Individualized
N/A
Ovarian
Bilateral salpingo-oophorectomy (BSO). Discuss the risks and benefits of concurrent hysterectomy at the time of BSO.
35 to 40 years, upon completion of childbearing
N/A
Consider options for ovarian cancer risk-reduction agents (i.e. oral contraceptives)
Individualized
N/A
Prostate
Consider prostate cancer screening.
40 years

Since mutation carriers are at an increased risk for more aggressive prostate cancer this information may be included as part of the risk and benefit discussion about prostate cancer screening.

Since mutation carriers are at an increased risk for more aggressive prostate cancer this information may be considered when choosing management options for men with a diagnosis of prostate cancer.

Annually
Consider mammography
50 years, or 10 years earlier than the youngest male breast cancer diagnosis in the family
Annually
Pancreatic
For patients with a family history of pancreatic cancer, consider available options for pancreatic cancer screening, including the possibility of endoscopic ultrasonography (EUS) and MRI/magnetic resonance cholangiopancreatography (MRCP). It is recommended that patients who are candidates for pancreatic cancer screening be managed by a multidisciplinary team with experience in screening for pancreatic cancer, preferably within research protocols.
Age 50, or 10 years younger than the earliest age of pancreatic cancer diagnosis in the family
Annually
Provide education about ways to reduce pancreatic cancer risk, such as not smoking and losing weight.

For Patients With A Cancer Diagnosis
For patients with a gene mutation and a diagnosis of cancer, targeted therapies may be available as a treatment option for certain tumor types (e.g., platinum chemotherapy, PARP-inhibitors)
