After treatment for early or locally-advanced breast cancer ends, many people are afraid they still have cancer or that their cancer will come back (breast cancer recurrence).
These fears are normal.
There are healthy ways to cope with the stress caused by these fears. For example, mindfulness meditation may help ease fears of recurrence .
For some people, talking to a counselor or joining a support group can be helpful. Your health care provider may be able to help you find a counselor or support group.

Breast cancer can recur at or near the original site (called local recurrence). It can also return and spread to other parts of the body (called metastasis or distant recurrence).
For people with no symptoms of metastases, blood and imaging tests (other than mammography) are not a standard part of follow-up care.
Using blood or imaging tests to check for early metastases in people with no symptoms of metastases does not increase survival or improve quality of life .
Learn about follow-up care after breast cancer treatment.
Learn more about breast cancer recurrence.
Most local recurrences occur within the first 5 years after diagnosis [108-109].
The risk of local recurrence varies from person to person and depends on the original breast cancer diagnosis and treatment.
Getting regular medical care after treatment is the best thing you can to do ensure a local recurrence is found early, when the chances of survival are highest.
If you have a local recurrence, you will need more treatment.

When breast cancer metastasizes, it most often spreads to the bones, lungs, liver or brain.
The risk of metastasis varies from person to person and depends on the original breast cancer diagnosis and treatment.

Breast cancer survivors have an increased risk of getting a new breast cancer compared to people who have never had breast cancer [110-113].
A new breast cancer is called a second primary breast cancer. Unlike a recurrence, which is a return of the first breast cancer, a second primary tumor is a new cancer unrelated to the first.

Although breast cancer survivors are at risk of a new breast cancer, preventive mastectomy of the healthy breast (contralateral prophylactic mastectomy) is not recommended for most survivors . For most survivors, this surgery does not improve survival [3,114].
Only some breast cancer survivors with a very high risk of a new breast cancer should consider prophylactic mastectomy. This includes women with a mutation in one of these genes :
These women should talk with their health care providers about whether contralateral prophylactic mastectomy is right for them.
Compared to other survivors, the risk of a second primary breast cancer is higher for those with a strong family history and those who carry a BRCA1 or BRCA2 gene mutation [115-121].
For women with a BRCA1/2 gene mutation, the chance of a contralateral breast cancer 10 years after diagnosis of the first cancer is about 10-30 percent compared to about 5-10 percent for women diagnosed with breast cancer without a BRCA1/2 mutation [115-121].
The lifetime risk of a second primary contralateral breast cancer is about 40-70 percent for women with a BRCA1/2 mutation [118,121].
Women who have a BRCA1/2 mutation also have an increased risk of ovarian cancer .
Breast cancer survivors with a BRCA1/2 mutation should talk with their health care providers about whether contralateral prophylactic mastectomy and/or prophylactic oophorectomy (removal of the ovaries) is right for them .

Some healthy behaviors may lower the risk of breast cancer recurrence and improve survival.
Other healthy behaviors have not yet been shown to impact breast cancer survival, but are part of a lifestyle that may help protect against other cancers and diseases.
A healthy lifestyle includes:

If you are being treated with hormone therapy (tamoxifen or aromatase inhibitors), it's important to take these drugs as prescribed. People who complete the full course of hormone therapy have a lower risk of [123-126]:
