Breast cancer

Introduction

Introduction

The breast is a glandular organ present in both sexes.  It is made up of lobes and lobules linked by ducts and surrounded by fatty tissue. Breast cancer is caused by uncontrolled proliferation of certain cells of the mammary gland.

One in eight women worldwide develop breast cancer during their lifetime and it is considered to be the most common malignancy among women globally (excluding skin tumors) and second in frequency to lung cancer. In Spain some 22,000 cases a year are diagnosed; the majority between 35 and 80 years of age, with a maximum between 45 and 65 years of age.

Early diagnosis plays an important role in the success of cancer treatment. The early diagnosis increases the chances of curing the disease.
