This mobile App is a medical calculator indicating the likelihood that a patient diagnosed with breast cancer will relapse from the cancer in five and ten years.

To calculate this likelihood we need to know the following patient parameters at the time of diagnosis: age, TNM stage, multicentricity and grade.

To give this likelihood the App will calculate a total score based on the risk afforded by the above parameters. A patient will have a greater risk of recurrence if that patient is older, have higher grade and stage, and there exists multicentricity.

According to the score obtained the patient will have a probability associated with relapsed.

If a patient has a high probability of recurrence, special emphasis should be placed on the follow-up.
