On the basis of their findings, the study authors concluded that despite the frequent use of screening mammography, 43% of breast cancers presented as a palpable mass or otherwise symptomatic presentation, whereas 57% were detected by mammography.
What are the odds a breast lump is cancerous?
Finding a lump in your breast can be frightening — but although breast cancer is the most common cancer found in women, most breast lumps are not cancer. In fact, more than 80 percent of them end up being benign. In a small percentage of women, a painful breast lump turns out to be cancer.

(Palpable means something that can be touched or felt.) Doing a mammogram or ultrasound (or both) of the palpable mass is usually the next step your doctor will take to evaluate the mass. A biopsy may then be done to figure out if the mass is cancer. Most palpable masses are benign (not cancer).
Can you tell if a lump is cancerous from an ultrasound?
Ultrasound images are not as detailed as those from CT or MRI scans. Ultrasound cannot tell whether a tumor is cancer. Its use is also limited in some parts of the body because the sound waves can’t go through air (such as in the lungs) or through bone.
Do cancerous breast lumps appear suddenly?
Though most breast lumps are benign, some do turn out to be cancerous. If a tumor is cancerous, it will continue to grow and invade normal nearby tissue. If it isn’t treated, it can spread to other areas in the body. Most cancerous breast tumors first appear as single, hard lumps or thickening under the skin.

What kind of breast lump should I worry about?
Lumps that feel harder or different from the rest of the breast (or the other breast) or that feel like a change are a concern and should be checked. This type of lump may be a sign of breast cancer or a benign breast condition (such as a cyst or fibroadenoma).
