The risk factor for increased incidence of relapse in stage I, carcinoma breast includes all except –
**Core Concept**
In stage I breast cancer, the risk of relapse is influenced by various factors, including tumor biology and patient characteristics. The presence of certain molecular or pathological features can increase the likelihood of recurrence.
**Why the Correct Answer is Right**
The correct answer is related to the presence of **estrogen receptor (ER) positivity**, which is a well-established prognostic factor for breast cancer. ER-positive tumors are more likely to recur, especially in younger patients. This is because ER-positive tumors are more likely to have **human epidermal growth factor receptor 2 (HER2) overexpression** or **high-grade histology**, both of which are associated with a higher risk of recurrence.
