BREAST CANCER
sTAGE 1

Early disease: tumour confined to the breast (node-negative)
sTAGE 2

Early disease: tumour spread to movable ipsilateral axillary node(s) (node-positive)
sTAGE 3

Locally advanced disease tumour spread to the superficial structures of the chest wall; involvement of ipsilateral internal mammary lymph nodes
sTAGE 4

Advanced (or metastatic) disease: metastases present at distant sites, such as bone, liver, lungs and brain and including supraclavicular lymph node involvement
The five-year survival rate for breast cancer if diagnosed with stage 1 to stage 3 is between 100% and 72%.
Once the cancer spreads to other parts of the body, the five-year survival rate drops to 22%.
You can improve your chances of early detection and treatment by:
- Developing a routine of conducting self-breast examinations
- Seeing your doctor if you notice any changes in your breasts
- Getting regular mammograms
Mammogram recommendations vary depending on age and risk, so make sure you talk to yoru doctor about when you should start and how frequently you should have a mammogram.
252,710 women in the United States will be diagnosed with invasive breast cancer.
63,410 women will be diagnosed with in situ breast cancer.
Estimated 2,470 men in the United States will be diagnosed with breast cancer.
41,070 (40,610 women and 460 men) will die from breast cancer this year.
The 5-year survival rate tells you whatpercent of people live at least 5 years after the cancer is found. Percent means how many out of 100.
The average 5-year survival rate for people with breast cancer is 90%. The average 10-year survival rate is 83%.
If the cancer is located only in the breast, the 5-year survival rate of people with breast cancer is 99%.
Sixty-one percent (61%) of cases are diagnosed at this stage.
If the cancer has spread to the regional lymph nodes, the 5-year survival rate is 85%.
If the cancer has spread to a distant part of the body, the 5-year survival rate is 26%.
It is important to note that these statistics are averages, and each person’s risk depends on many factors, including the size of the tumor, the number of lymph nodes that contain cancer and other features of the tumor that affect how quickly a tumor will grow and how well the treatment works.
