Screening and Diagnosis of Breadt Cancer

looking for evidence of disease before signs or symptoms appear is the key to finding breast cancer in its early, treatable stages. Depending on your age and risk factors, screening may include breast self-examination, examination by your nurse or doctor (clinical breast exam), mammograms (mammography) or other tests.
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
Unless you have a family history of cancer or other factors that place you at high risk, the American Cancer Society recommends having clinical breast exams once every three years until age 40. After that, the American Cancer Society recommends having a yearly clinical exam.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).
Mammogram
A mammogram, which uses a series of X-ray images of your breast tissue, is currently the best imaging technique for detecting tumors before you or your doctor can feel them. For that reason, the American Cancer Society has long recommended screening mammography for all women over 40
