A breast lump that's painless, hard, irregularly shaped and different from surrounding breast tissue might be breast cancer. Skin covering the lump may look red, dimpled or pitted like the skin of an orange. Your breast size and shape may change, or you may notice discharge from the nipple.
Fibroadenomas are solid, smooth, firm, noncancerous (benign) lumps that are most commonly found in women in their 20s and 30s. They are the most common benign lumps in women and can occur at any age. They are increasingly being seen in postmenopausal women who are taking hormone therapy.
Breast Cancer Treatment
What typically differentiates a benign breast lump from a cancerous breast lump is movement. That is, a fluid-filled lump that rolls between the fingers is less likely to be cancerous than a hard lump in your breast that feels rooted in place. Another rule of thumb has to do with pain.
A tumor may feel more like a rock than a grape. A cancerous lump is usually hard, not soft or squishy. And it often has angular, irregular, asymmetrical edges, as opposed to being smooth, Dr. Comander says.
"A breast lump will feel like a distinct mass that's noticeably more solid than the rest of your breast tissue. Lumps can range in size — from the size of a pea to larger than a golf ball — and may or may not be movable," says Dr. Joshi.
Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.
Commonly developing from the mammary glands or ducts, such malignant lumps generally (about 50 percent) appear in the upper, outer quadrant of the breast, extending into the armpit, where tissue is thicker than elsewhere.
Sometimes doctors recognize cysts during a physical exam, but they often rely on diagnostic imaging. Diagnostic images help your doctor figure out what's inside the lump. These types of imaging include ultrasounds, CT scans, MRI scans, and mammograms.
Some are not found until a physical or imaging exam. Most breast lumps are benign (non-cancerous). Your doctor will likely perform a physical exam to evaluate a breast lump. To determine whether that lump is benign, your doctor will likely order a mammogram and breast ultrasound.
Where are breast cysts usually located? Cysts are fluid-filled lumps or bumps that can appear anywhere under the skin, including within the breast. In breast cysts, fluid fills the lobules. Breast cysts are typically located in the upper outer quadrant or the central margins (in the middle, close to the nipple).
A moveable lump means that you can easily move it beneath the skin with your fingertips.
If you feel the same lumpiness in both breasts, or there isn't one lump that's firmer than the others, it's most likely your normal breast tissue. That said, if you find a lump that feels harder, in only one breast, or one that just feels different than what you usually feel, address it with your doctor.
A lump or mass in the breast is the most common symptom of breast cancer. Lumps are often hard and painless, although some are painful.
Sometimes breast lumps develop that are benign (noncancerous). Only 3% to 6% of breast lumps are due to breast cancer. 1 Self-exams each month may be helpful in identifying the lumps, but an exam done by a healthcare provider is needed to find out for sure what's going on in your breast.
A breast lump that's painless, hard, irregularly shaped and different from surrounding breast tissue might be breast cancer. Skin covering the lump may look red, dimpled or pitted like the skin of an orange. Your breast size and shape may change, or you may notice discharge from the nipple.
A lump in your breast can be anywhere, but a cancerous lump most often occurs in the upper-outer section of the breast. It can be located near the surface or deeper inside the breast, close to the chest wall. It can also occur in the armpit area, where there is more breast tissue (a.k.a. the "tail" of the breast).
Breast cancer lumps can vary in size. Typically, a lump has to be about one centimeter (about the size of a large lima bean) before a person can feel it; however, it depends on where the lump arises in the breast, how big the breast is, and how deep the lesion is.
Most breast cancers are found in women who are 50 years old or older. Some women will get breast cancer even without any other risk factors that they know of.
Both benign and malignant masses can be rounded and mobile. Only when cancers are quite advanced are they fixed to skin or the underlying chest wall, and not moveable. Any new, persistent, or changing lump in your breast should be evaluated by your physician.
See a GP if:
your lump is painful, red or hot. your lump is hard and does not move. your lump lasts more than 2 weeks. a lump grows back after it's been removed.
No, not every lump is cancerous. However, if you find or feel a new lump on your body, please seek medical attention.
