Breast lumps are common, especially in women ages 30 to 50. A
number of conditions can result in a lump or lumps in your breast. Most of
these conditions are harmless or of minor concern.
Generalized breast lumpiness usually
feels like lots of little bumps (nodularity) or as though some areas of the
breast are thicker or denser than other areas. Your breasts also may feel
tender. The lumps may occur in both breasts around the nipple and in the upper,
outer part of the breasts, especially before your menstrual period. The lumps
may come and go and change size in just a few days. Generalized lumpiness was
once thought to be abnormal and was even called fibrocystic breast disease, but
it is so common that it is now considered normal. Breast lumpiness usually goes
menopause but may be found in women who are taking
hormone therapy after menopause.
Following are other types of breast lumps and their
Cysts and abscess lumps
fluid-filled sacs in the breast. They feel smooth or rubbery and move about
under the fingers. They can be quite painful or tender, or they may be
painless. Cysts are caused by the hormones that control the menstrual cycle.
Cysts are rare in women older than 50 and are not related to breast cancer. If
you have a cyst, your doctor may drain (aspirate) it to help
relieve the pain and confirm the diagnosis.
Sebaceous cysts are caused by plugged ducts at the
site of a hair follicle. Like a cyst, they move freely under the fingers.
Hormone stimulation or injury may cause them to enlarge. A sebaceous cyst that
does not cause symptoms does not require medical treatment. Removal usually
involves making a small incision in the skin and removing the entire sac so
that it does not return.
pockets of infection within the breast. They may be quite painful, and the skin
over the breast may be red or feel hot or solid. You may feel feverish or ill.
Abscesses are treated with antibiotics and surgery to drain the abscess. They
are most common in women who are breast-feeding.
Fat necrosis is a condition in which the
normal fat cells of the breast go through a change and become round lumps. The
lumps may or may not be painful and may be firm. The skin over the lump may be
red or look bruised. Fat necrosis may occur after a bruise or other injury to
the chest or breast and can occur from weeks to years after an injury. Fat
necrosis usually goes away without treatment but can form permanent scar tissue
that may show up as an abnormality on a
Lipomas are noncancerous lumps
of fatty tissue. They can be small or large. A woman may have just one or
several lipomas at once.
Adenomas are noncancerous abnormal growths of
the glandular tissue in the breast. The most common growths,
fibroadenomas, are somewhat more common in women in
their 20s and in women of African descent. They usually feel round and firm and
have smooth borders. They may move a little under the fingers, be tender, and
change with the menstrual cycle. Adenomas are not related to breast
Intraductal papillomas are
growths in the ducts of the breast. They usually feel like lumps just under the
nipple and can cause a bloody discharge from the nipple. Women close to
menopause may have only one growth. Several growths in both breasts are more
common in younger women.
usually feels like a hard or firm lump (nodule). It usually is irregular in
shape (it does not have smooth edges) and may feel like it is attached (fixed)
to skin or tissue deep inside the breast so that it cannot be moved without
moving breast tissue. Breast cancer is rarely painful and can occur anywhere in
the breast or nipple.
Blood clots in
a vein (thrombophlebitis) can feel like a lump. The phlebitis
affects the large vein that normally crosses the chest to the underarm area
(axilla). Symptoms include pain, redness, warmth, and lumpiness along the
course of the vein. Blood clots in the breast or on the chest wall are rare.
It can be difficult to tell what is causing a lump in your breast.
Call your doctor if you feel a new lump in your breast or if you
have generalized breast lumpiness and you notice a distinct lump in your breast
that is not like the rest of your breast (dominant lump). A dominant lump in
the breast is any lump that is new, larger, harder, or different in any other
way from the rest of the breast tissue.
