| PathologicalLymphNode | Localized adenopathy should prompt a search for an adjacent precipitating lesion and an examination of other nodal areas to rule out generalized lymphadenopathy. In general, lymph nodes greater than 1 cm in diameter are considered to be abnormal. Supraclavicular nodes are the most worrisome for malignancy. | Localized adenopathy should prompt a search for an adjacent precipitating lesion and an examination of other nodal areas to rule out generalized lymphadenopathy.

| Nodule | A small collection of tissue that is palpable (can be felt) at any level of the skin (in the epidermis, dermis, or subcutis) or in another tissue of the body. | A small collection of tissue that is palpable (can be felt) at any level of the skin (in the epidermis, dermis, or subcutis) or in another tissue of the body. |

| MastitisArea | Mastitis is an inflammation of breast tissue that sometimes involves an infection. The inflammation results in breast pain, swelling, warmth and redness. ... Mastitis most commonly affects women who are breast-feeding (lactation mastitis). But mastitis can occur in women who aren't breast-feeding and in men. | Mastitis is an inflammation of breast tissue that sometimes involves an infection.

| Mass | A lump in the body. It may be caused by the abnormal growth of cells, a cyst, hormonal changes, or an immune reaction. | A lump in the body. It may be caused by the abnormal growth of cells, a cyst, hormonal changes, or an immune reaction. |
| Lipoma | A lipoma is a slow-growing, fatty lump that's most often situated between your skin and the underlying muscle layer. | A lipoma is a slow-growing, fatty lump that's most often situated between your skin and the underlying muscle layer. |
| Hematoma | A breast hematoma is a collection of blood that forms under the skin's surface. It's not unlike having a large bruise in your breast. The mass it forms is not cancerous, but it can sometimes lead to inflammation, fever, skin discoloration, and may leave behind scar tissue that mimics the shape of a breast tumor. | A breast hematoma is a collection of blood that forms under the skin's surface.

| Hamartoma | A hamartoma is a mostly benign, focal malformation that resembles a neoplasm in the tissue of its origin. | A hamartoma is a mostly benign, focal malformation that resembles a neoplasm in the tissue of its origin. |
| ForeignBody | A foreign object is something that is in the body but doesn't belong there. | A foreign object is something that is in the body but doesn't belong there. |
| FluidCollection | A mild buildup of fluid is common after surgery and does not necessarily mean a seroma will appear. | A mild buildup of fluid is common after surgery and does not necessarily mean a seroma will appear. |
| FibrocysticTissue | Fibrocystic breast changes lead to the development of fluid-filled round or oval sacs (cysts) and more prominent scar-like (fibrous) tissue, which can make breasts feel tender, lumpy or ropy. | Fibrocystic breast changes lead to the development of fluid-filled round or oval sacs (cysts) and more prominent scar-like (fibrous) tissue, which can make breasts feel tender, lumpy or ropy. |
| FibroadenomaDegeneration | Predominant cystic degeneration of the tumor that grossly constitutes most of the tumor, so called 'cystic fibroadenoma,' is rare. | Predominant cystic degeneration of the tumor that grossly constitutes most of the tumor, so called 'cystic fibroadenoma,' is rare. |
| Fibroadenoma | Fibroadenoma is the most common type of benign breast tumor, and most don't increase your risk of breast cancer. Although women of any age can develop fibroadenomas, they usually occur in younger, premenopausal women. | Fibroadenoma is the most common type of benign breast tumor, and most don't increase your risk of breast cancer.

| FatNecrosis | Fat necrosis is a lump of dead or damaged breast tissue that sometimes appears after breast surgery, radiation, or another trauma. Fat necrosis is harmless and doesn't increase your cancer risk. It usually isn't painful, but it can cause anxiety. You should tell your doctor about any lumps you feel in your breast. | Fat necrosis is a lump of dead or damaged breast tissue that sometimes appears after breast surgery, radiation, or another trauma.

| DuctEctasia | Mammary duct ectasia occurs when a milk duct beneath the nipple becomes wider (dilated) and filled with fluid. The milk duct can then become blocked or clogged with a thick, sticky substance. | Mammary duct ectasia occurs when a milk duct beneath the nipple becomes wider (dilated) and filled with fluid.

| Cyst | Circumscribed, round or oval, fluid-filled mass with an imperceptible wall; usually bright on T2W images. | Circumscribed, round or oval, fluid-filled mass with an imperceptible wall; usually bright on T2W images. |
| Calcification | Typically benign | Typically benign |
| BrachytherapyCatheter | Brachytherapy is seldom used in children. ... Temporary brachytherapy places radioactive material inside a catheter for a specific amount of time and then removes it. It is given at a low-dose rate (LDR) or high-dose rate (HDR). Permanent brachytherapy is also called seed implantation. | Brachytherapy is seldom used in children. ...

| Seroma | A seroma is a pocket of clear serous fluid that sometimes develops in the body after surgery. This fluid is composed of blood plasma that has seeped out of ruptured small blood vessels and inflammatory fluid produced by the injured and dying cells. | A seroma is a pocket of clear serous fluid that sometimes develops in the body after surgery.

| SignalVoidArea | The term 'flow void' is widely used among radiologists and others involved in MR imaging. It refers to the low signal seen in vessels that contain vigorously flowing blood and is generally synonymous with vascular patency. Flow voids can also be seen with active flow or pulsations of other fluids, like CSF or urine. | The term 'flow void' is widely used among radiologists and others involved in MR imaging.
