# Breast Cancer Prediction App


Kanker payudara adalah kanker paling umum di kalangan wanita di dunia. Ini menyumbang 25% dari semua kasus kanker, dan mempengaruhi lebih dari 2,1 Juta orang pada tahun 2015 saja. Ini dimulai ketika sel-sel di payudara mulai tumbuh di luar kendali. Sel-sel ini biasanya membentuk tumor yang dapat dilihat melalui sinar-X atau dirasakan sebagai benjolan di area payudara.

Tantangan utama untuk mendeteksinya adalah bagaimana mengklasifikasikan tumor menjadi ganas (kanker) atau jinak (non kanker).
