Screening and diagnosis breast cancer

Breast self-examination
Breast self-examination is an option beginning at age 20. By becoming proficient at breast self-examination and familiar with the usual appearance and feel of your breasts, you may be able to detect early signs of cancer. Learn how your breasts typically look and feel and watch for changes. If you detect a change, promptly bring it to your doctor's attention. Have your doctor review your examination technique if you'd like input or you have questions.

Clinical breast exam
During a clinical breast exam, your health care provider checks your breasts. You may be asked to raise your arms over your head, let them hang by your sides, or press your hands against your hips.
Your health care provider looks for differences in size or shape between your breasts. The skin of your breasts is checked for a rash, dimpling, or other abnormal signs. Your nipples may be squeezed to check for fluid.
Using the pads of the fingers to feel for lumps, your health care provider checks your entire breast, underarm, and collarbone area. A lump is generally the size of a pea before anyone can feel it. The exam is done on one side, then the other. Your health care provider checks the lymph nodes near the breast to see if they are enlarged.

A thorough clinical breast exam may take about 10 minutes
During this exam, your doctor examines your breasts for lumps or other changes. He or she may be able to feel lumps you miss when you examine your own breasts and will also check for enlarged lymph nodes in your armpit (axilla)

Screening mammogram

• Women in their 40s and older should have mammograms every 1 to 2 years. A mammogram is a picture of the breast made with x-rays.
• Women who are younger than 40 and have risk factors for breast cancer should ask their health care provider whether to have mammograms and how often to have them.
• Two types of mammograms include:
• Screening mammograms. Screening mammograms are performed on a regular basis about once a year to check your breast tissue for any changes since your last mammogram.
• Diagnostic mammograms. Your doctor may recommend a diagnostic mammogram to evaluate a breast change detected by you or your doctor. During a diagnostic mammogram, the radiologist performing the exam can take additional views to evaluate the area of concern more closely.
