1. What is Breast Cancer Prognosis?

Breast cancer prognosis refers to the likely outcome or course of the disease, typically expressed as survival rates. It helps guide treatment decisions and provides patients with important information about their condition.

2. How Does the Calculator Work?

The calculator uses a simplified model based on three key factors:

Where:

• \( Stage \) — Cancer stage (I-IV)
• \( Age \) — Patient's age in years
• \( Tumor Size \) — Maximum diameter of tumor in millimeters

Explanation: The model weights these factors differently, with stage being the most significant predictor, followed by tumor size and age.

3. Importance of Prognosis Estimation

Details: Accurate prognosis estimation is crucial for treatment planning, patient counseling, and clinical decision-making in breast cancer management.

4. Using the Calculator

Tips: Enter the cancer stage (I-IV), patient's age (18+ years), and tumor size in millimeters. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What other factors affect breast cancer prognosis?
A: Additional factors include hormone receptor status, HER2 status, grade, lymph node involvement, and molecular subtype.

Q2: How accurate is this calculator?
A: This provides a general estimate. Actual prognosis should be determined by an oncologist using comprehensive clinical data.

Q3: Does this apply to all breast cancer types?
A: The calculator provides general estimates. Specific subtypes may have different prognostic profiles.

Q4: How often should prognosis be reassessed?
A: Prognosis should be reassessed after significant treatments or changes in disease status.

Q5: Can this predict individual outcomes?
A: No calculator can predict individual outcomes with certainty. This provides population-based estimates.
