A breast self-exam for breast awareness is a safe way to become familiar with the typical look and feel of your breasts.
However, there are some limitations and risks, including:
Worry caused by finding a lump
Most of the changes or lumps people find in their breasts aren't cancerous. Still, finding something suspicious in your breast can make you worry about what it may mean. You may endure several days of worry until you can see your healthcare professional.
Other tests may be needed
If you discover a suspicious lump, you may need other tests and procedures to check it out. This might include imaging tests such as a diagnostic mammogram or a breast ultrasound. You also may have a procedure to remove breast tissue for testing, called a biopsy. If it turns out the lump isn't cancer, you might feel that you've had an invasive procedure without needing one.
Overestimating the benefits
A breast self-exam doesn't replace a breast exam by your healthcare professional, called a clinical breast exam. It also doesn't replace a screening mammogram. Becoming familiar with the typical look and feel of your breasts can be used with breast cancer screening but can't replace it.
