Galactocele Health Dictionary

The female breasts may be expected to undergo hormone-controlled enlargement at puberty, and later in pregnancy, and the glandular part of the breast undergoes evolution (shrinkage) after the menopause. The breast can also be affected by many di?erent diseases, with common symptoms being pain, nipple discharge or retraction, and the formation of a lump within the breast.

Benign disease is much more common than cancer, particularly in young women, and includes acute in?ammation of the breast (mastitis); abscess formation; and benign breast lumps, which may be ?broadenosis – di?use lumpiness also called chronic mastitis or ?brocystic disease – in which one or more ?uid-?lled sacs (cysts) develop.

Women who are breast feeding are particularly prone to mastitis, as infection may enter the breast via the nipple. The process may be arrested before a breast abscess forms by prompt treatment with antibiotics. Non-bacterial in?ammation may result from mammary duct ectasia (dilatation), in which abnormal or

blocked ducts may over?ow. Initial treatments should be with antibiotics, but if an abscess does form it should be surgically drained.

Duct ectasia, with or without local mastitis, is the usual benign cause of various nipple complaints, with common symptoms being nipple retraction, discharge and skin change.

Breast lumps form the chief potential danger and may be either solid or cystic. Simple examination may fail to distinguish the two types, but aspiration of a benign cyst usually results in its disappearance. If the ?uid is bloodstained, or if a lump still remains, malignancy is possible, and all solid lumps need histological (tissue examination) or cytological (cell examination) assessment. As well as having their medical and family history taken, any women with a breast lump should undergo triple assessment: a combination of clinical examination, imaging

– mammography for the over-35s and ultrasonagraphy for the under-35s – and ?ne-needle aspiration. The medical history should include details of any previous lumps, family history (up to 10 per cent of breast cancer in western countries is due to genetic disposition), pain, nipple discharge, change in size related to menstrual cycle and parous state, and any drugs being taken by the patient. Breasts should be inspected with the arms up and down, noting position, size, consistency, mobility, ?xity, and local lymphadenopathy (glandular swelling). Nipples should be examined for the presence of inversion or discharge. Skin involvement (peau d’orange) should be noted, and, in particular, how long changes have been present. Fine-needle aspiration and cytological examination of the ?uid are essential with ULTRASOUND, MAMMOGRAPHY and possible BIOPSY being considered, depending on the patient’s age and the extent of clinical suspicion that cancer may be present.

The commonest solid benign lump is a ?broadenoma, particularly in women of childbearing age, and is a painless, mobile lump. If small, it is usually safe to leave it alone, provided that the patient is warned to seek medical advice if its size or character changes or if the lump becomes painful. Fibroadenosis (di?use lumpiness often in the upper, outer quadrant) is a common (benign) lump. Others include periductal mastitis, fat NECROSIS, GALACTOCELE, ABSCESS, and non-breast-tissue lumps – for example, a LIPOMA (fatty tissue) or SEBACEOUS CYST. A woman with breast discharge should have a mammograph, ductograph, or total duct excision until the cause of any underlying duct ectasia is known. Appropriate treatment should then be given.

Malignant disease most commonly – but not exclusively – occurs in post-menopausal women, classically presenting as a slowly growing, painless, ?rm lump. A bloodstained nipple discharge or eczematous skin change may also be suggestive of cancer.

The most commonly used classi?cation of invasive cancers has split them into two types, ductal and lobular, but this is no longer suitable. There are also weaknesses in the tumour node metastases (TNM) system and the International Union Against Cancer (UICC) classi?cation.

The TNM system – which classi?es the lump by size, ?xity and presence of affected axillary glands and wider metastatic spread – is best combined with a pathological classi?cation, when assessing the seriousness of a possibly cancerous lump. Risk factors for cancer include nulliparity (see NULLIPARA), ?rst pregnancy over the age of 30 years, early MENARCHE, late MENOPAUSE and positive family history. The danger should be considered in women who are not breast feeding or with previous breast cancer, and must be carefully excluded if the woman is taking any contraceptive steroids or is on hormone-replacement therapy (see under MENOPAUSE).

Screening programmes involving mammography are well established, the aim being to detect more tumours at an early and curable stage. Pick-up rate is ?ve per 1,000 healthy women over 50 years. Yearly two-view mammograms could reduce mortality by 40 per cent but may cause alarm because there are ten false positive mammograms for each true positive result. In premenopausal women, breasts are denser, making mammograms harder to interpret, and screening appears not to save lives. About a quarter of women with a palpable breast lump turn out to have cancer.

Treatment This remains controversial, and all options should be carefully discussed with the patient and, where appropriate, with her partner. Locally contained disease may be treated by local excision of the lump, but sampling of the glands of the armpit of the same side should be performed to check for additional spread of the disease, and hence the need for CHEMOTHERAPY or RADIOTHERAPY. Depending on the extent of spread, simple mastectomy or modi?ed radical mastectomy (which removes the lymph nodes draining the breast) may be required. Follow-up chemotherapy, for example, with TAMOXIFEN (an oestrogen antagonist), much improves survival (it saves 12 lives over 100 women treated), though it may occasionally cause endometrial carcinoma. Analysis in the mid-1990s of large-scale international studies of breast-cancer treatments showed wide variations in their e?ectiveness. As a result the NHS has encouraged hospitals to set up breast-treatment teams containing all the relevant health professional experts and to use those treatments shown to be most e?ective.

As well as the physical treatments provided, women with suspected or proven breast cancer should be o?ered psychological support because up to 30 per cent of affected women develop an anxiety state or depressive illness within a year of diagnosis. Problems over body image and sexual diffculties occur in and around one-quarter of patients. Breast conservation and reconstructive surgery can improve the physical effects of mastectomy, and women should be advised on the prostheses and specially designed brassieres that are available. Specialist nurses and self-help groups are invaluable in supporting affected women and their partners with the problems caused by breast cancer and its treatment. Breast Cancer Care, British Association of Cancer United Patients (BACUP), Cancerlink, and Cancer Relief Macmillan Fund are among voluntary organisations providing support.... breasts, diseases of

The small prominence at the tip of each breast. Women’s nipples contain tiny openings through which milk can pass. The nipple and the areola, a surrounding area of dark skin, both increase in size during pregnancy. Involuntary muscle in the nipple allows it to become erect.

Structural defects of the nipple are rare. An inverted nipple is usually a harmless abnormality of development. Nipple inversion that develops in older women is mostly due to ageing, but mammography may be advisable to rule out the possibility of cancer.

Cracked nipples, common in the last months of pregnancy and during breastfeeding, may lead to infective mastitis. Washing, drying, and moisturizing the nipple daily can help to prevent cracking. Papilloma of the nipple is a noncancerous swelling attached to the skin by a stalk. Paget’s disease of the nipple appears initially as persistent eczema of the nipple and is due to a slow-growing cancer arising in a milk duct. Surgical treatment is required.Discharge from the nipple occurs for various reasons.

A clear, straw-coloured discharge may develop in early pregnancy; a milky discharge may occur after breast-feeding is over.

Galactorrhoea (milk discharge in someone who is not pregnant or breast-feeding) may be caused by a hormone imbalance, or, rarely, a galactocele (a cyst under the areola).

A discharge containing pus indicates a breast abscess.

A bloodstained discharge may be due to a noncancerous breast disorder or cancer.... nipple
