Breast cancer screening typically involves a combination of methods to detect breast cancer at an early stage, even before symptoms appear. Here are the commonly used screening methods:

1. Mammography: This is the most common screening tool for breast cancer. It uses low-dose X-rays to create images of the breast tissue. Mammograms can detect small tumors or abnormalities that may not be felt during a physical examination.

2. Clinical Breast Examination (CBE): During a CBE, a healthcare provider examines your breasts and underarms for any lumps, changes in size or shape, or other abnormalities. It is recommended to have a CBE every 1-3 years for women aged 20-39, and annually for women aged 40 and above.

3. Breast Self-Examination (BSE): BSE involves checking your own breasts regularly to become familiar with their appearance and feel. While BSE is no longer recommended as a standalone screening method, it can help you become aware of any changes in your breasts and promptly report them to your healthcare provider.

It's important to note that screening recommendations may vary depending on factors such as age, family history, and personal risk factors. It's best to consult with your healthcare provider to determine the most appropriate screening plan for you. Regular screening can help detect breast cancer early, when it is more treatable.
