About 4% of all breast cancers diagnosed in the U.S. occur in women under 40 [259].
A breast cancer diagnosis is shocking, especially for young women. At a time in life most often focused on family and career, issues of treatment, recovery and survivorship suddenly take top priority.
Survival
With treatment, the chances of survival for young women diagnosed with early breast cancer are good.
However, survival tends to be worse for women under 40 than for older women. This is because breast cancers in younger women can be more aggressive than breast cancers in older women [260].
Breast cancers in younger women are more likely to be [260]:
- Fast-growing
- Higher grade
- Hormone receptor-negative
Each of these factors makes breast cancer more aggressive and more likely to need chemotherapy [260].
Screening mammography isn’t recommended for women under 40 unless they have an increased risk of breast cancer. So, breast cancers found in younger women may be larger and more likely to be lymph node-positive than those found in older women who get regular mammograms.
However, tumor size isn’t as strongly related to breast cancer survival as other tumor factors. A large tumor may have better survival than a small tumor, based on biomarkers such as hormone receptor status and HER2 status.
Genetic testing
If you’re diagnosed with breast cancer at age 40 or younger, you have an increased risk of having an inherited gene mutation related to breast cancer [8]. The National Comprehensive Cancer Network (NCCN) recommends you get genetic testing for BRCA1, BRCA2 and possibly other inherited gene mutations that increase breast cancer risk [8].
Learn more about genetic testing.
Treatment
Age
Age itself doesn’t greatly affect breast cancer treatment.
Treatment is based mainly on cancer stage and tumor characteristics, such as the biomarkers hormone receptor status and HER2 status.
However, age may play a role in the choice of certain treatment options. For example, younger women may be more likely than older women to get breast reconstruction after a mastectomy.
Learn more about factors that affect treatment options.
Menopausal status
Whether or not a woman has gone through menopause is important for some breast cancer treatments.
Women with hormone receptor-positive breast cancers are treated with hormone therapy. Hormone therapy drug options depend on a woman’s menopausal status.
For example, premenopausal women may get ovarian suppression in addition to tamoxifen or an aromatase inhibitor.

Breast cancer treatment and fertility
Young women with breast cancer may be concerned about loss of fertility.
Chemotherapy can damage the ovaries.
Both chemotherapy and tamoxifen can cause irregular periods or stop periods altogether. They both also tend to bring on natural menopause earlier than normal, especially in women who are over 40 during treatment [40].
Chemotherapy and fertility
With chemotherapy, the loss of periods may be permanent. Some chemotherapy combinations are less likely to cause permanent menopause than others.
Women under 40 at the time of treatment are more likely than older women to have their periods return after chemotherapy [40]. The risk of permanent menopause increases with age [40].
Hormone therapy and fertility
With tamoxifen, periods may continue, or they may stop and then return after treatment ends (although they may be irregular).
If ovarian suppression is added to tamoxifen or given with an aromatase inhibitor, periods will usually stop temporarily and return after treatment ends.
However, even in women whose periods return, the time it takes to complete treatment can shorten the window of time to have children. And menopause may come sooner if a woman gets chemotherapy in addition to hormone therapy.
Because of the danger of birth defects, women should not become pregnant while taking hormone therapy [11]. Hormone therapy is taken for 5-10 years and during this time, natural fertility may decline.
Taking a break from hormone therapy to have a child
A recent study looked at women ages 42 and younger who had stage I-III hormone receptor-positive breast cancer and wished to try and have a child [261]. The women had been taking hormone therapy (tamoxifen (with or without ovarian suppression) or an aromatase inhibitor with ovarian suppression) for 18-30 months [261].
The women in the study paused hormone therapy for up to 2 years to try to have a child [261]. After that time, women went back on hormone therapy so they could complete their planned 5-10 years of treatment [261].
After 3 years of follow-up, findings showed no evidence of an increased rate of breast cancer recurrence (breast cancer returning in the breast) or metastasis (breast cancer spreading to other parts of the body) in the women who paused hormone therapy [261-262].
If you’re on hormone therapy and wish to have a child, talk with your oncologist about your risk of breast cancer recurrence and whether it makes sense for you to take a break from treatment to try to have a child (and then return to hormone therapy).
Other drug therapies and fertility
There are a number of new drug therapies for early breast cancer, including antibody-drug conjugate therapy, CDK4/6 inhibitor therapy, immunotherapy and PARP inhibitor therapy. We don’t yet understand the impact these new therapies might have on future fertility.
Preserving fertility
Storing eggs
Before treatment begins, you can help preserve your ability to have children in a few ways.
The most common way to preserve fertility is to store your eggs (fertilized or unfertilized) before chemotherapy begins. Some of your eggs are collected, frozen and stored. The eggs may be fertilized by sperm from a spouse, partner or donor. Or you may store unfertilized eggs, which don’t require a sperm donor.
After treatment, the eggs can be thawed, and if they were frozen unfertilized, they are fertilized. Then the eggs are implanted into the uterus.
Breast cancer treatment may be delayed while eggs are collected (and if a sperm donor is needed to fertilize the eggs before they are stored). Studies suggest these treatment delays are not long and should not affect survival [263-266].

Protecting the ovaries
Chemotherapy attacks fast-growing cells. These include cancer cells as well as healthy cells in other parts of the body, like the ovaries.
Drugs like goserelin (Zoladex), leuprolide (Lupron) and triptorelin (Trelstar) can shut down the ovaries during chemotherapy.
Studies have shown these drugs may protect the ovaries from damage during chemotherapy, lower the chances of early menopause and help preserve fertility [267-269].
Ovarian suppression with goserelin or leuprolide is also part of breast cancer treatment for some premenopausal women with hormone receptor-positive early breast cancer. Some women may start ovarian suppression before chemotherapy begins. This not only starts their hormone therapy, but also may protect their ovaries.
Talking with a fertility specialist
If you wish to have a child after breast cancer treatment, discuss your options with your health care provider (and if possible, a fertility specialist) before making treatment decisions.
Meeting with a fertility specialist as early as possible (before surgery) offers the widest range of options.
Hormonal birth control after a breast cancer diagnosis
If you’ve been diagnosed with breast cancer and are going to use birth control, talk with your health care provider about safe options. For women who’ve had breast cancer, there are concerns about using birth control containing hormones (such as birth control pills) and the risk of breast cancer recurrence [11]. So, it’s important to talk with your provider before you begin using birth control containing hormones.
Clinical trials for young women with breast cancer
Research is ongoing to improve fertility preservation and breast cancer treatment for young women.
After discussing the benefits and risks with your health care provider, you may want to consider joining a clinical trial if there’s one right for you.
If you’re considering a clinical trial of fertility preservation, talking with a fertility specialist is also helpful.

Prescription drug assistance
Chemotherapy drug costs can quickly become a financial burden for you and your family.
Many insurance companies offer prescription drug plans. One may already be included in your policy, or you may be able to buy an extra plan for prescriptions.
Some drugs are off-patent and may have a generic form. Generic drugs cost less than the name brands but are just as effective.
You may also qualify for programs that help with drug costs or offer low-cost or free prescriptions.

Other medical and personal expenses
Insurance issues (for example, a claim is denied) can be a major concern while you’re being treated for breast cancer.
Paying out-of-pocket expenses related to your treatment can also be a burden. This can lead to struggles paying other expenses such as rent, groceries and car payments. There are financial assistance programs that may help.
Learn about insurance and financial assistance programs.
Learn about maintaining health insurance if you lose your job, change jobs, or need to take time off during your breast cancer treatment.
Travel, lodging, childcare and eldercare
Getting to your breast cancer treatments can be hard, especially if you don’t live near the hospital or medical center.
There may be resources available if you need a ride to and from treatment or help with childcare or eldercare. Family and friends often want to help but don’t know how. These are great ways for them to get involved. It’s OK to ask for help.
There may be some programs that help with local or long-distance transportation and lodging (if you need a place to stay overnight during treatment).
There may also be programs to help you with childcare or eldercare costs.
