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.
