What is breast cancer?
Breast cancer is the uncontrolled growth of abnormal cells in the breast. It is the most common cancer affecting women, with approximately one in eight women being diagnosed with breast cancer in their lifetime.
Women with breast cancer can present in two ways. Symptomatic patients usually undergo a series of investigations after presenting to their doctor with a breast complaint, whereas asymptomatic patients are usually identified through screening programs but do not have any symptoms.
Breast cancer is usually diagnosed using a series of tests which can include breast examination, mammogram or ultrasound, as well as a biopsy. This is when a fine needle is used to sample parts of the breast lesion which are then examined under the microscope.
