Relative Survival Rate By Stage
The survival rates by stage are based on the stage at the time of diagnosis. Youâve probably been given a number and letter for your cancer stage. Here, the terms localized, regional, and distant are used instead of numbers and letters. Hereâs what they mean and the 5-year relative survival rates for each:
- Localized breast cancer is only in the breast. This includes stage IA , some IIA , and some IIB . The 5-year relative survival rate is 99%.
- Regional breast cancer has spread to nearby tissue or lymph nodes. This includes stage IB , some IIA , some IIB , and all stage III . The 5-year relative survival rate is 86%.
- Distant breast cancer has spread to other parts of the body. This includes stage IV, pronounced âstage 4â). The 5-year relative survival rate is 28%.
Where Do These Numbers Come From
The American Cancer Society relies on information from the Surveillance, Epidemiology, and End Results database, maintained by the National Cancer Institute , to provide survival statistics for different types of cancer.
The SEER database tracks 5-year relative survival rates for breast cancer in the United States, based on how far the cancer has spread. The SEER database, however, does not group cancers by AJCC TNM stages . Instead, it groups cancers into localized, regional, and distant stages:
- Localized: There is no sign that the cancer has spread outside of the breast.
- Regional: The cancer has spread outside the breast to nearby structures or lymph nodes.
- Distant: The cancer has spread to distant parts of the body such as the lungs, liver or bones.
Examples Of Rates Versus Numbers
Say, town A has a population of 100,000 and town B has a population of 1,000. Over a year, say there are 100 breast cancer deaths in town A and 100 breast cancer deaths in town B.
The number of breast cancer deaths in each town is the same. However, many more people live in town A than live in town B. So, the mortality rates are quite different.
In town A, there were 10 breast cancer deaths among 100,000 people. This means the mortality rate was less than 1 percent .
In town B, the mortality rate was 10 percent .
Although the number of deaths was the same in town A and town B, the mortality rate was much higher in town B than in town A .
Lets look at another example. In 2021, its estimated among women there will be :
- 100 breast cancer deaths in Washington, D.C.
- 720 breast cancer deaths in Alabama
- 4,730 breast cancer deaths in California
Of the 3, California has the highest number of breast cancers. However, that doesnt mean it has the highest breast cancer rate. These numbers dont take into account the number of women who live in each state. Fewer women live in Alabama and Washington, D.C. than live in California.
Other factors may vary by state as well, such as the age and race/ethnicity of women. So, to compare breast cancer mortality rates, we need to look at mortality rates.
In 2021, the estimated mortality rates are :
- 26 per 100,000 women in Washington, D.C.
- 22 per 100,000 women in Alabama 22
- 19 per 100,000 women in California 20

Incidence Rates And The Number Of New Cases
To know whether or not breast cancer rates are changing over time, you have to compare rates, rather than the number of new cases.
For example, lets compare the number of new cases of breast cancer in U.S. in 2009 to the number of new cases in 2016. In 2009, there were an estimated 192,370 new cases of breast cancer in U.S. women . In 2016, there were an estimated 246,660 new cases .
Although more breast cancer cases occurred in 2016 than in 2009, this doesnt mean the rate of breast cancer increased over this time period.
We expect the number of cases to increase over time because the population of the U.S. increases over time . The more people there are, the more cancers there will be.
Our population is also living longer . Since age increases the risk of breast cancer, we expect to have more breast cancers over time.
To know if breast cancer rates are changing over time, we look at incidence rates, rather than the number of new cases. The incidence rate shows the number of breast cancer cases in a set population size. Its usually written as the number of cases in a population of 100,000 people.
The breast cancer incidence rate among women in 2009 was 131 and the estimated breast cancer incidence rate in 2016 was also 131 . This means there were 131 breast cancer cases per 100,000 women in the U.S. population in both time periods.
So, although the number of breast cancer cases increased over time, breast cancer rates were fairly stable.
Data Source And Methods
The data shown in this report reflect information collected by CDCs National Center for Health Statistics from death certificates filed in all 50 states and the District of Columbia and compiled into the National Vital Statistics System. Deaths were classified using the International Classification of Diseases, 10th Revision. Cancer deaths were identified using underlying cause-of-death codes C00-C97 . Rates were age-adjusted to the 2000 US standard population.

Age And Stage For Breast Cancer Prognosis
Stage 1 Breast Cancer: The highest survival rates for stage I breast cancer tends to be for women aged 50 to 69 years. Women under 39 have the poorest overall survival rates for stages I and II breast cancers.
Stage II, III and IV Breast Cancers: Women between the ages of 40 and 49 showed the highest survival rates for more advanced breast cancers. Conversely, as we have seen, women over 70 years showed the lowest survival rates for Stages III and IV breast cancer.

Age And Stage For Breast Cancer Survival
Research over the years has generally shown that women under 40 years have a poorer than average prognosis. Interestingly, this factor is particularly relevant when the breast cancer is axillary node negative.
A medical study published in 2015 examined 4,453 Swedish women diagnosed with invasive breast cancer between 1961 and 1991 regarding age at diagnosis.
This research showed that women under 40 years had a higher mortality rate both for 5 year and 10 year survival rate.
However, older ladies between ages 70 and 79 and over 80 years had a higher mortality rate in both the 5 and 10 year follow up periods. The statistically worst outcome, after all adjustments for other factors, is for ladies over 80 years.
Furthermore, an earlier taken from SEER statistics between the years of 1988 to 2003 found that women under 40 years had lower rates of survival for stage I and II breast cancers.
Conversely, younger women tended to have a more favourable chance of survival at stage III and IV compared with those over 70 years of age.

What Is A 5
A relative survival rate compares women with the same type and stage of breast cancer to women in the overall population.For example, if the 5-year relative survival rate for a specific stage of breast cancer is 90%, it means that women who have that cancer are, on average, about 90% as likely as women who dont have that cancer to live for at least 5 years after being diagnosed.
Breast Cancer Mortality By Age
Breast cancer mortality is strongly related to age, with the highest mortality rates being in older people. In the UK in 2016-2018, on average each year almost half of deaths were in people aged 75 and over. This largely reflects higher incidence and lower survival for breast cancer in older people.
Age-specific mortality rates rise steadily from around age 30-34 and more steeply from around age 70-74. The highest rates are in the 90+ age group for females and the 85 to 89 age group for males. Mortality rates are significantly higher in females than males in a number of age groups.The gap is widest at age 50 to 54, when the age-specific mortality rate is 334 times higher in females than males.

Health Disparities In Young African Americans
In addition to these unique issues, research has shown that young African American women face even greater challenges.
- African American women under age 35 have rates of breast cancer two times higher than caucasian women under age 35.14
- African Americans under age 35 die from breast cancer three times as often as caucasian women of the same age.14
- Researchers believe that access to healthcare and the quality of healthcare available may explain these disparities. But scientists continue to investigate.
- Research also shows that young African Americans are more likely to get aggressive forms of breast cancer than anyone else.14
When Should Black Women Start Getting Breast Cancer Screenings
According to research published in JAMA Oncology, breast cancer diagnosed before age 50 represents 23 percent of all breast cancers in Black women, compared to only 16 percent of all breast cancers in white women.Breast cancer screening guidelines from multiple national organizations do not acknowledge the prevalence of breast cancer cases in Black women under the age of 50. Organizations that recommend women start getting regular mammograms at age 50 include the U.S. Preventive Services Task Force, the American Academy of Family Practice, and the American College of Physicians.
Through support from their provider, friends, and family members, Black women can be encouraged to seek preventive screenings and tests for breast cancer at a younger age.

Understanding Breast Cancer Survival Rates
Prognosis varies by stage of breast cancer.
Non-invasive and early stage invasive breast cancers have a better prognosis than later stage cancers .
Breast cancer thats only in the breast and has not spread to the lymph nodes has a better prognosis than breast cancer thats spread to the lymph nodes.
The poorest prognosis is for metastatic breast cancer , when the cancer has spread beyond the breast and nearby lymph nodes to other parts of the body.

Mortality Rates Versus Number Of Breast Cancer Deaths
Sometimes its useful to have an estimate of the number of people expected to die from breast cancer in a year. This numbers helps show the burden of breast cancer in a group of people.
Numbers, however, can be hard to compare to each other. To compare mortality rates in different populations, we need to look at mortality rates rather than the number of breast cancer deaths.
Survival Rate With Metastatic Breast Cancer
Many people wonder about the life expectancy for stage 4 breast cancer . It’s important to note that everyone is different and survival rates vary widely. There are some people who survive many years and even decades with stage 4 disease. At the same time, it’s important to understand that stage 4 breast cancer isn’t curable.
It can be helpful to look at current statistics and consider the many variables that affect life expectancy. While it’s important not to raise false hope, it may help to know the reality that there are some long-term survivors.
Some people want to know the statistics, but many don’t. If you’re living with stage 4 breast cancer, there is absolutely no requirement that you know the prognosis. The information provided here is only for those who truly wish to know what the current research iseven this research has many limitations.

What Is The Chance I Could Die In The Next 5 Years
The average 5-year survival rate for all people with breast cancer is 89%. The 10-year rate is 83%, and the 15-year rate is 78%. If the cancer is located only in the breast , the 5-year survival rate is 99%. More than 70% of breast cancers are diagnosed at an Early Stage.
All survival statistics are primarily based on the stage of breast cancer when diagnosed. Some of the other important factors are also listed below that affect survival.
Stage 0 breast cancer can be also described as a pre-cancer. If you have DCIS you can be quite confident you will do well. DCIS does not spread to other organs. What can be concerning is when an invasive cancer grows back in the area of a prior lumpectomy for DCIS. This type of local recurrence does carry a risk to your life. Luckily, this does not happen frequently. Also, be aware that those who have had DCIS in the past are at a higher risk for developing an entirely new, invasive breast cancer. Take our video lesson on Non-Invasive DCIS to learn more.
Stage I invasive breast cancer has an excellent survival rate. The chance of dying of Stage I breast cancer within five years of diagnosis is 1 to 5% if you pursue recommended treatments.
Stage II breast cancer is also considered an early stage of breast cancer. There is a slightly increased risk to your life versus a Stage I breast cancer. Altogether, the risk of Stage II breast cancer threatening your life in the next 5 years is about 15%.
