There’s no easy answer: It depends on your personal risk factors.
If you’re someone who worries about dealing with breast cancer at some point in your life, one of the best things you can do is begin breast cancer screening—including mammograms—at the recommended age. Catching breast cancer early tends to improve your prognosis, since early cancers that have not spread to other parts of the body are more easily curable.
“Any woman who has a question about when to start screening for breast cancer should meet with their physician or healthcare provider and have a discussion about what’s best for them,” says Brenda Panzera, MD, oncologist at The Mount Sinai Hospital and Lenox Hill Hospital.
The exact age you should begin breast cancer screening depends on your own personal risk factors. Learn more about what it means to be average risk, moderate risk, and high risk for breast cancer.
Mammograms for an Average-Risk Individual
“An average-risk woman is an individual who has no family history or personal history of breast cancer, is not a breast cancer gene carrier, and has not previously had radiation to the chest,” says Dr. Panzera.
Different organizations have slightly different recommendations, but the United States Preventive Services Task Force (USPSTF) recommends getting a mammogram every two years for women between the ages of 50 and 74—but potentially as early as 40. “Healthcare professionals will usually speak with women about the pros and cons of screening beginning at that age,” says Dr. Panzera.
Mammograms for a Moderate-Risk Individual
“A moderate-risk individual is an individual who has not previously had breast cancer, but has a family member, particularly a first-degree family member, who has had breast cancer, but does not carry one of the known breast cancer genes,” says Dr. Panzera.
Although considered at a higher risk of breast cancer than those of average risk, a moderate-risk individual has the same recommendations—but they may benefit from starting at age 40, according to the USPSTF. The American Cancer Society (ACS) also recommends that women in this group should get mammograms every year.
Regardless, when moderate-risk individuals should start mammograms “needs to be very carefully individualized for each person,” says Dr. Panzera.
Mammograms for a High-Risk Individual
“A high-risk individual is an individual who has previously had breast cancer themselves, or who has a first-degree family member with breast cancer who is a known gene carrier, but that person has not been tested for the gene,” says Dr. Panzera. Women who are a known gene carrier are also considered high risk.
High-risk individuals should start getting breast cancer screenings and mammograms beginning at age 30, according to ACS. However, this should also be carefully discussed with a healthcare provider to consider individual circumstances.
Breast cancer screenings have so many benefits—whether it’s alleviating anxiety by assuring you do not have breast cancer, or it’s helping diagnose breast cancer early so you can begin breast cancer treatment if necessary.

00:00:00.200 --> 00:00:01.799
00:00:01.800 --> 00:00:05.599
Any woman who has a question about when to start screening
00:00:05.600 --> 00:00:10.066
for breast cancer should meet with their physician or healthcare provider
00:00:10.067 --> 00:00:14.066
and have a discussion about what's best for them.
00:00:14.067 --> 00:00:19.332
00:00:19.333 --> 00:00:22.366
An average-risk woman is an individual who has
00:00:22.367 --> 00:00:25.799
no family history or personal history of breast cancer,
00:00:25.800 --> 00:00:28.299
is not a breast cancer gene carrier,
00:00:28.300 --> 00:00:31.799
and has not previously had radiation to the chest.
00:00:31.800 --> 00:00:34.166
In terms of when we recommend that women
00:00:34.167 --> 00:00:38.232
begin breast cancer screening, between the ages of 40 and 49.
00:00:38.233 --> 00:00:41.066
Healthcare professionals will usually speak with women
00:00:41.067 --> 00:00:45.666
about the pros and cons of screening beginning at that age.
00:00:45.667 --> 00:00:48.366
A moderate-risk individual is an individual
00:00:48.367 --> 00:00:51.899
who has not previously had breast cancer,
00:00:51.900 --> 00:00:55.466
but has a family member, particularly a first-degree family member,
00:00:55.467 --> 00:00:58.866
who has had breast cancer, but does not carry
00:00:58.867 --> 00:01:01.532
one of the known breast cancer genes.
00:01:01.533 --> 00:01:05.232
The recommendations for screening for a moderate-risk individual
00:01:05.233 --> 00:01:07.799
are the same as an average-risk individual,
00:01:07.800 --> 00:01:12.399
and that needs to be very carefully individualized for each person.
00:01:12.400 --> 00:01:15.932
A high-risk individual is an individual who has previously
00:01:15.933 --> 00:01:17.866
had breast cancer themselves,
00:01:17.867 --> 00:01:21.499
or who has a first-degree family member
00:01:21.500 --> 00:01:25.199
with breast cancer who is a known gene carrier,
00:01:25.200 --> 00:01:28.699
but that person has not been tested for the gene,
00:01:28.700 --> 00:01:34.432
or if an individual is a known breast cancer gene carrier.
00:01:34.433 --> 00:01:37.766
For women who are anxious about having a mammogram,
00:01:37.767 --> 00:01:40.299
I think it's important to remember that once you've had
00:01:40.300 --> 00:01:43.732
that first mammogram, the anxiety will lessen
00:01:43.733 --> 00:01:46.466
with subsequent mammograms, and the benefit
00:01:46.467 --> 00:01:50.299
of having the mammogram far outweighs the risk,
00:01:50.300 --> 00:01:53.732
and your healthcare providers are here to help guide you
00:01:53.733 --> 00:01:57.666
through the process of doing the next steps,
00:01:57.667 --> 00:02:01.466
getting the diagnosis, having the appropriate treatment,
00:02:01.467 --> 00:02:05.432
and then being followed, so that you can get to the other side
00:02:05.433 --> 00:02:09.666
and live a full life, hopefully without cancer.
