Understanding the stage of the cancer helps doctors to develop a prognosis and design a treatment plan for every cancer patient. Breast cancer stages range from 0 to Ⅳ, lower numbers indicate earlier stages of cancer, while higher numbers reflect late-stage cancers. Below are breast cancer stages, along with their corresponding survival rate.
Stage 0 - the average 5 years survival rate is about 99%
This stage describes noninvasive breast cancer.
Stage Ⅰ- the average 5 years survival rate is about 95%
This stage is an early stage of invasive breast cancer. The tumor measures no more than 2 cm in diameter and no lymph nodes are involved – the cancer hasn’t spread outside the breast.
Stage Ⅱ- the average 5 years survival rate is about 80%-90%
This stage describes invasive breast cancers.
The tumor measures less than 2 cm in diameter but has spread to lymph nodes under the arm.
The tumor is between 2 and 5 cm in diameter and may or may not have spread to lymph nodes under the arm.
The tumor is larger than 5 cm in diameter but hasn’t spread to any lymph nodes.
Stage Ⅲ - the average 5 years survival rate is about 40-70%
Stage Ⅲ breast cancers are subdivided into three categories – ⅢA, ⅢB, and ⅢC. stage Ⅲ cancers haven’t spread to distant sites.
Stage ⅢA tumor is larger than 5 cm and has spread to one to three lymph nodes under the arm.
Stage ⅢB breast cancer, a tumor of any size has spread to tissues near the breast (the skin and chest muscles) and may have spread to lymph nodes within the breast or under the arm.
Stage ⅢC cancer is a tumor of any size that has spread to lymph nodes above or beneath the collarbone and near the neck.
Stage Ⅳ - the average survival time is 3 years
Stage Ⅳ breast cancer has spread to distant parts of the body, such as lungs, liver, bones or brain.
