Start by standing in front of a mirror to look at your breasts, with your hands on your hips (as this optimizes the positioning of your breasts so that you can look at them and compare them). [4] X Trustworthy Source BreastCancer. org Patient-focused nonprofit organization providing resources for those affected by breast cancer Go to source Things to look for include: breasts that are similar to their normal in terms of size, shape, and color; no swelling; no skin changes; no nipple discharge or nipple changes; and no redness or soreness. The next step in your breast self-exam is to raise your arms above your head, and to examine your breasts for the same features listed above. [5] X Trustworthy Source BreastCancer. org Patient-focused nonprofit organization providing resources for those affected by breast cancer Go to source This change in position of your arms alters how your breasts sit, and is another way to identify any changes. The next part of the breast self-exam is done lying down. [6] X Trustworthy Source BreastCancer. org Patient-focused nonprofit organization providing resources for those affected by breast cancer Go to source Lift your right arm over your head. With your left hand, apply firm pressure to your right breast. Move your fingers in a circular motion around the nipple, the surrounding tissue and the armpit. [7] X Research source Be sure to cover the full surface area of the breast, from the collarbone to the bottom of the rib cage, and from the armpit to the breastbone. Raise your left arm and repeat the process examining your left breast, surrounding tissue and the armpit with your right hand. Doing a breast exam in the shower also works. [8] X Research source You may actually be better at reading your breast when your fingers are wet and soapy as your fingers will glide over your breast tissue more easily.

It’s not unusual to develop breast lumps for a short duration of time; most often, these are related to the menstrual cycle (they are called “physiological breast lumps” and come and go each month in sync with your menstrual cycle). In order to distinguish “physiological breast lumps” (related to your period) from worrisome ones, watch to see whether the lump grows and then shrinks again within the month, and whether this pattern repeats monthly with your cycle. If this is not the case, or if the lump continues to grow, it is always best to seek the advice of your physician. The best time to do breast self-examination is one week before your period starts (as this is the time when it is least likely, hormonally, to have lumps related to your period). If you are post-menopausal or have irregular periods, you can examine your breasts on the same day of each month to keep your self-examination process as consistent as possible.

Look for a bloody or pus-like nipple discharge. Watch for a red or pink rash near or around the nipple. Notice any changes in your nipple, especially if it becomes inverted. Observe breast skin. If it becomes thick, scaly, dry, dimpled, red or pink, talk to your doctor.

Medical professionals are well-trained in how to evaluate and assess breast lumps, and in particular in how to rule out breast cancer. [12] X Research source If in doubt, do not hesitate to ask for doctors advice. Breast cancer is a realistic concern for many women (being the number one most frequent cancer diagnosis in women). [13] X Research source One in nine women are diagnosed with breast cancer in their life, so if in doubt get your breast lump checked out by a doctor sooner rather than later. Most breast lumps are benign (not worrisome), and many cancer diagnoses are completely treatable if caught sooner rather than later. Keep in mind, however, that breast cancer under the age of 20 is very rare, and it is very uncommon under the age of 30.

Mammograms are the number one way in which breast cancers are caught and diagnosed. [14] X Research source It can be used as a screening test (routine test for any woman over the age of 40 to rule out breast cancer even without symptoms or lumps), and also as a diagnostic test (for women with a breast lump to gather further information to determine whether or not the lump is of concern). For a young patient with dense breast tissue, however, an MRI may be a better test than mammogram. People who receive a mammogram for diagnostic reasons (to determine whether or not their breast lump is worrisome) will likely also receive additional tests to add to the information your doctor has to work with, to determine whether or not she is concerned about your breast lump.

An ultrasound can also provide further information to see whether a biopsy (sample of the breast tissue taken with a needle and examined by doctors under the microscope) is needed. [16] X Research source

If the lump is in fact diagnosed as breast cancer, you will be referred to an oncologist (cancer specialist) and perhaps a surgeon for surgical, hormonal, or chemotherapy treatments, depending upon the severity. Again, it is important to be aware that the great majority of breast lumps are not cancer; [18] X Research source however, it is always best to see your physician and to have the recommended tests done in order to rule out any possibility, and to get treatment as soon as possible (which results in the most successful outcomes) if you are in fact diagnosed with breast cancer. At times, a breast MRI or ductogram will be used as “diagnostic tests” by your doctor, but these are significantly less common than mammograms, ultrasounds, and breast biopsies.
