What is the survival rate for stage II breast cancer?

    In stage II breast cancer, the tumor is typically larger than in stage I and may have spread to nearby lymph nodes but not to distant parts of the body.

    Survival rates provide an estimate of the percentage of people with the same type and stage of breast cancer who are still alive after a certain amount of time. These rates are based on previous outcomes and can help understand the likelihood of successful treatment. However, they are estimates and may not predict individual cases.

    • The 5-year relative survival rate for women in the US with non-metastatic invasive breast cancer is 91%, while the 10-year rate is 85%.
    • If breast cancer is only present in the breast, the 5-year relative survival rate is 99%, with about 66% of women being diagnosed at this stage.
    • If cancer has spread to regional lymph nodes, the 5-year relative survival rate is 86%. If it has spread to distant parts of the body, the rate drops to 30%.

    Survival rates for breast cancer differ depending on various factors, such as the cancer stage, a person's age and overall health, and the effectiveness of the treatment plan. I hope this information is helpful

    For individuals with stage II breast cancer, two important considerations can potentially impact survival outcomes. Firstly, a study conducted in Alberta, Canada, examined the survival rates of breast cancer patients specifically in stages II and III who underwent different surgical treatments. The findings revealed that patients who opted for breast-conserving surgery (BCS) along with radiotherapy had better survival rates compared to those who underwent a mastectomy. The unadjusted 5-year all-cause survival probabilities were as follows: 94% for BCS plus radiotherapy, 83% for mastectomy, and 74% for BCS alone (1). While this study focused on stages II and III, it would be prudent to discuss with your oncologist whether these findings apply to your particular situation.

    Moreover, it is worth noting that engaging in physical activity after a breast cancer diagnosis can have positive implications for survival outcomes. Research has shown that regular physical activity is associated with lower all-cause mortality, breast cancer mortality, and potentially a reduced risk of recurrence. Among breast cancer survivors, those who engage in the highest level of recreational physical activity tend to experience better survival outcomes (2). Therefore, alongside your cancer treatment, incorporating regular physical activity into your routine may serve as a helpful strategy to enhance overall well-being and potentially improve survival prospects.

    It is important to consult with your healthcare team, including your oncologist, to determine the most appropriate treatment options and lifestyle strategies tailored to your circumstances.
