Breast Implant: From 2 Different Sources


An artificial structure surgically introduced into the breast to increase its size (see mammoplasty).
Health Source: BMA Medical Dictionary
Author: The British Medical Association
a prosthesis to replace breast tissue that has been removed surgically during a simple *mastectomy in the treatment of breast cancer. The type of implant in current use is a silicone sac filled with silicone gel; it has recently been found that coating the sac with polyurethane to give a textured surface reduces the incidence of fibrosis around the implant and consequent hardening of breast tissue. Alternatively, an implant with a soya-oil filling may be used. The implant is inserted subcutaneously at the time of operation (the skin and nipple are retained), and follow-up radiotherapy is not normally required. Implants are also used to augment existing breast tissue.

Breast Feeding

This is the natural way to feed a baby from birth to WEANING. Human milk is an ideal food, containing a proper balance of nutrients as well as an essential supply of antibodies to protect the infant against infections. Breast feeding also strengthens the physical bond between mother and child. For the ?rst few weeks, feeding should be on demand. Di?culties over breast feeding, discouragement from health-care providers and the pressures of modern life, especially for working mothers, can make it hard to continue breast feeding for more than a few weeks, or even to breast feed at all. Sometimes infections occur, producing soreness and even an abscess. Mothers should seek advice from their health visitor about breast feeding, especially if problems arise.... breast feeding

Cochlear Implant

A device used to treat profoundly deaf people who are not helped by hearing aids. A cochlear implant consists of tiny electrodes surgically implanted in the cochlea deep in the inner ear and a receiver that is embedded in the skull just behind and above the ear. A microphone, sound processor, and transmitter are worn externally. A cochlear implant does not restore normal hearing, but it enables patterns of sound to be detected. Combined with lip-reading, it may enable speech to be understood.... cochlear implant

Implant

Any material, either natural or artificial, inserted into the body for medical or cosmetic purposes. For example, artificial joints can replace diseased structures and breast implants can improve appearance. Implants are also used to maintain proper functioning of an internal organ, treat certain disorders, or deliver drugs or hormones.... implant

Breast

Either 1 of the 2 mammary glands, which, in women, provide milk to nourish a baby and are secondary sexual characteristics. In males, the breast is an immature version of the female breast. At puberty, a girl’s breasts begin to develop: the areola (the circular area of pigmented skin around the nipple) swells and the nipple enlarges. This is followed by an increase in glandular tissue and fat. The adult female breast consists of 15–20 lobes of milk-secreting glands embedded in fatty tissue. The ducts of these glands have their outlet in the nipple. Bands of fine ligaments determine the breast’s height and shape. The areolar skin contains sweat glands, sebaceous glands, and hair follicles.

The size and shape and general appearance of the breasts may vary during the menstrual cycle, during pregnancy and lactation, and after the menopause.

During pregnancy, oestrogen and progesterone, secreted by the ovary and placenta, cause the milkproducing glands to develop and become active and the nipple to become larger.

Just before and after

childbirth, the glands in the breast produce a watery fluid known as colostrum.

This fluid is replaced by milk a few days later.

Milk production and its release is stimulated by the hormone prolactin.... breast

Breast Cancer

A cancerous tumour of the breast. The incidence is raised in women whose menstrual periods began at an early age and whose menopause was late; in those who had no children or had their first child later in life; in those with mothers or sisters who had breast cancer; and in those who are obese. The disease is also more common in countries in which the typical diet contains a lot of fat. One form of breast cancer has a genetic component; 2 genes called BRAC1 and BRAC2 have been identified and appear to be involved in this type of breast cancer.

The first sign of breast cancer may be a painless lump. Other symptoms may include a dark discharge from the nipple, retraction (indentation) of the nipple, and an area of dimpled, creased skin over the lump. In 90 per cent of the cases, only 1 breast is affected. The cancer may be suspected after discovering a lump during breast self-examination or mammography. If a lump is detected, cells will be collected from it by needle aspiration or surgical biopsy. If the lump is cancerous, the treatment given depends on the woman’s age, the size of the tumour, whether or not there are signs of spread to the lymph nodes, and the sensitivity of the tumour cells to hormones, as assessed in the laboratory. A small tumour, with no evidence of having spread outside the breast, is removed surgically. Lymph nodes in the armpit are also commonly removed at the same time. Surgery may be combined with radiotherapy and/or anticancer drugs.

Secondary tumours in other parts of the body are treated with anticancer drugs and hormones. Regular check-ups are required to detect recurrence or the development of a new cancer in the other breast. If the cancer recurs, it can be controlled, in some cases, for years by drugs and/or radiotherapy.... breast cancer

Breast Screening

A set of investigations aimed at the early detection of breast cancer. It includes self-screening by monthly examination of the breasts, and formal programmes of screening by palpation and mammography in special clinics. In the UK the NHS o?ers regular mammography examinations to all women between 50 and 64 years of age; in 1995–6, 1.1 million women were screened – 76 per cent of those invited. More than 5,500 cancers were detected – 5.3 per 1,000 women screened.... breast screening

Cochlear Implants

A cochlear implant is an electronic device, inserted under a general anaesthetic, which stimulates the auditory system, restoring partial hearing in profound sensory deafness. Although there are many types of cochlear implant, they all consist of a microphone, a signal processor, a signal coupler (transmitter and receiver), and an array of electrodes. Most are multi-channel implants. The microphone and signal processor are worn outside the body, like a conventional hearing aid: they receive sound and convert it into an electronic signal which is transmitted through the skin to the receiver. Here the signal is transmitted to the array of electrodes which stimulates the cochlear nerve. Although cochlear implants do not provide normal hearing, most profoundly deaf patients who receive a cochlear implant are able to detect a variety of sounds, including environmental sounds and speech. The duration of hearing-loss and age at implantation are among the many factors which in?uence the results (see DEAFNESS).... cochlear implants

Cancer - Breast

Commonest form of cancer in women. Overall mortality remains about 50 per cent at five years. Appears to run in families. Strikes hard unmarried women. Married women who have no children. Those who do not nurse their babies, or who are infertile and have no child before thirty. Eight out of ten chest lumps are benign.

Symptoms. A small lump comes to light while washing, a discharge from the nipple, change in nipple size and colour, irregular contour of the breast surface. Though tissue change is likely to be a cyst, speedy diagnosis and treatment are necessary. Some hospital physicians and surgeons are known to view favourably supportive herbal aids, and do not always think in terms of radical mastectomy. Dr Finlay Ellingwood, Chicago physician (1916) cured a case by injection of one dram Echinacea root extract twice a week into the surrounding tissues.

The condition is believed to be due to a number of causes including suppression of ovulation and oestrogen secretion in pregnant and lactating women. A high fat diet is suspected of interference with the production of oestrogen. Some women are constitutionally disposed to the condition which may be triggered by trauma or emotional shock. Increase in incidence in older women has been linked with excessive sugar consumption. “Consumption overwhelms the pancreas which has to ‘push it out’ to all parts of the body (when broken down by the digestive process) whether they need it or not. The vital organs are rationed according to their requirements of nutrients from the diet. What is left over has to ‘go into store elsewhere’. And the breast is forced to take its share and store it. If it gets too much, for too long, it may rebel!” (Stephen Seely, Department of Bacteriology and Virology, Manchester)

“Women who nurse their babies less than one month are at an increased risk for breast cancer. The longer a woman breast-feeds – no matter what her age – the more the risk decreases. (Marion Tompson, co-founder, The La Leche League, in the American Journal of Epidemiology)

Lactation reduces the risk of pre-menopausal breast cancer. (Newcomb P.A. et al New England Journal of Medicine, 330 1994)

There is currently no treatment to cure metastatic breast cancer. In spite of chemotherapy, surgery and radiotherapy survival rate has not diminished. Herbs not only have a palliative effect but, through their action on hormone function offer a positive contribution towards overcoming the condition. Their activity has been widely recorded in medical literature. Unlike cytotoxic drugs, few have been known to cause alopecia, nausea, vomiting or inflammation of the stomach.

Treatment by a general medical practitioner or oncologist.

Special investigations. Low radiation X-ray mammography to confirm diagnosis. Test for detection of oestrogen receptor protein.

Treatment. Surgery may be necessary. Some patients may opt out from strong personal conviction, choosing a rigid self-disciplined approach – the Gentle Way. Every effort is made to build up the body’s natural defences (immune system).

An older generation of herbalists believed tissue change could follow a bruise on the breast, which should not be neglected but immediately painted with Tincture Arnica or Tincture Bellis perennis.

Vincristine, an alkaloid from Vinca rosea (Catharanthus roseus) is used by the medical profession as an anti-neoplastic and anti-mitotic agent to inhibit cell division.

Topical. Treatments believed to be of therapeutic value or for use as a soothing application.

(1) Cold poultice: Comfrey root.

(2) Poultice of fresh Marshmallow root pulped in juicer.

(3) Injection of Extract Greater Celandine (Chelidonium), locally, gained a reputation in the Eclectic school.

(4) The action of Blood root (Sanguinaria) is well known as a paint or injection.

(5) Ragwort poultice: 2oz Ragwort boiled in half a pint potato water for 15 minutes. See: POULTICE.

(6) Popular Russian traditional remedy: Badiaga (Spongilla fluviatilis), fresh water sponge gathered in the autumn; dried plant rubbed to a powder. Poultice.

(7) Maria Treben’s Poultice: Carefully washed fresh Plantain leaves, pulped, and applied direct to the lesion.

(8) If lymph glands are affected, apply Plantain poultice to glands.

(9) Dr Brandini’s treatment. Dr Brandini, Florence, used 4 grains Citric Acid (prepared from lemons) in 1oz (30ml) water for ulcerated cancer of the breast considered incurable. “The woman’s torments were so distressing that neither she nor other patients could get any rest. Applying lint soaked in the solution, relief was instantaneous. Repeated, it was successful.”

(10) Circuta leaves. Simmered till soft and mixed with Slippery Elm bark powder as a poultice morning and night.

(11) Decoction. Simmer gently Yellow Dock roots, fine cut or powdered, 1oz to 1 pint, 20 minutes. Saturate lint or suitable material and apply.

(12) Yellow Dock ointment. Half ounce Lobelia seed, half ounce Yellow Dock root powder. Baste into an ointment base. See: OINTMENT BASE.

(13) Infusion, for use as a wash. Equal parts: Horsetail, Red Clover, Raspberry leaves. 1oz to 1 pint boiling water infuse 15 minutes.

(14) Dr Christopher’s Ointment. Half an ounce White Oak, half an ounce Garden Sage, half an ounce Tormentil, half an ounce Horsetail, half an ounce Lemon Balm. Method: Boil gently half an hour in quart water, strain. Reduce to half a pint by simmering. Add half a pound honey. Bring to boil. Skim off scum. Allow cool. Apply: twice daily on sores.

(15) Dr Finlay Ellingwood. Poke root juice. “Fresh juice from the stems, leaves and roots applied directly to diseased tissue. Exercises a selective action; induces liquefaction and promotes removal, sometimes healing the open wound and encouraging scar formation. Masses of such tissue have been known to be destroyed in a few weeks with only a scar, with no other application but the fresh juice. Produces pain at first, but is otherwise harmless.”

(16) Lesion painted with Mandrake resin. (American Podophyllum)

(17) Dust affected parts with Comfrey powder. Mucilage from Comfrey powder or crushed root with the aid of a little milk. See: COMFREY.

(18) Dr Samuel Thomson’s Cancer Plaster. “Take heads of Red Clover and fill a kettle. Boil in water for one hour. Remove and fill kettle with fresh flower heads. Boil as before in the same liquor. Strain and press heads to express all the liquor. Simmer over a low fire till of the consistency of tar. It must not burn. Spread over a piece of suitable material.”

(19) Wipe affected area with cut Houseleek. (Dr Wm Boericke)

(20) Chinese Herbalism. Take 1-2 Liang pulverised liao-ko-wang (Wickstroemia indica), mix with cold boiled water or rice wine for local compress. Also good for mastitis.

(21) Italian women once used an old traditional remedy – Fenugreek tea.

(22) A clinical trial of Vitamin D provided encouraging results. Patients with locally advanced breast cancer were given a highly active Vitamin D analogue cream to rub on their tumours. “It was effective in one third of the tumours,” said Professor Charles Coombes, clinical oncologist, Charing Cross Hospital, London.

Diet. “A diet rich in cereal products (high in dietary fibre) and green leafy vegetables (antioxidants) would appear to offer women some protection against breast cancer due to the relation between fibre and oestrogen metabolism. Meat-free diet. In a study of 75 adolescent girls, vegetarians were found to have higher levels of a hormone that women suffering from breast cancer often lack. (Cancer Research) Supplements. Daily. Chromium. Selenium (600mcg). Zinc chelate (100mg morning and evening). Beta carotene. “Low levels of Selenium and Vitamins A and E are shown in breast cancer cases.” (British Journal of Cancer 49: 321-324, 1984).

Vitamins A and D inhibit virus penetration in healthy cell walls. Multivitamin combinations should not include Vitamin B12, production of which in the body is much increased in cancerous conditions. Vitamins B-complex and C especially required.

Note: A link between sugar consumption and breast cancer has been reported by some authorities who suggest that countries at the top of the mortality table are the highest also in sugar consumption; the operative factor believed to be insulin.

Screening. Breast screening should be annual from the age of forty.

General. Mothers are encouraged to breast-feed children for the protection it offers against mammary malignancy. (Am.J. Obstet. Gyn. 15/9/1984. 150.)

Avoidance of stress situations by singing, playing an instrument. Adopt relaxation techniques, spiritual healing and purposeful meditation to arouse the immune system; intensive visualisation. Avoid the carcinogens: smoking, alcohol.

Fibrocystic Breast Disease (fbd)

Most lumps are harmless, including cysts (adenosis) and benign tumours. Not forerunners of cancer. Largely due to hormone imbalance. Fluid may be aspirated from a cyst. Thickened patches of fibrous tissue are freely movable and occur chiefly during years of menstruation depending upon the presence of oestrogen. An accurate diagnosis is necessary by a competent authority. Excessive sugar consumption suspected.

Prominent cyst formations have been reduced, even eliminated by Poke root, internally and externally, though surgery is sometimes indicated. Diuretics influence the kidneys to expel more body fluids and are sometimes helpful to reduce size. Cold water packs may be applied to the affected area two or more times daily, as practical.

Alternatives. Tea. Formula. Equal parts: Ground Ivy, Clivers, Horsetail. One heaped teaspoon to each cup boiling water; infuse 15 minutes. 1 cup morning and evening.

Poke root. Tablets, powders. Tincture. 5-10 drops in water 3 times daily.

Evening Primrose oil. Two 500mg capsules, 3 times daily. Trials carried out by departments of Surgery at the University of Wales and the University of Dundee found Evening Primrose oil effective and safe. Poultice. Poke root. Horsetail.

Diet. As salt favours retention of fluid in cystic tissue it should be restricted.

Supplements. Daily. Beta carotene; B-complex; B6, Vitamin C 1g; Zinc. Vitamin E contra-indicated.

Implantation, Egg

Attachment of a fertilized ovum (egg) to the wall of the uterus.

It occurs about 6 days after fertilization, when the blastocyst (early embryo) comes into contact with the wall of the uterus.

As the cells of the developing embryo continue to divide, the outer cell layer penetrates the lining of the uterus to obtain oxygen and nutrients from the mother’s blood; later, this layer develops into the placenta.

The embryo usually implants in the upper part of the uterus; if it implants low down near the cervix, placenta praevia may develop.

Rarely, implantation occurs outside the uterus, possibly in a fallopian tube, resulting in an ectopic pregnancy.... implantation, egg

Breast, Disorders Of The

Disorders affecting the breast that are mostly minor and respond readily to treatment. The most important causes of problems are infection, such as mastitis, tumours, and hormonal changes. Breast cysts, fibroadenomas, other noncancerous tumours, or, more rarely, breast cancer may occur. Breast pain and tenderness is common just before menstruation or when a woman is taking hormones. Before menstruation, breasts may become bigger and lumpy. Such lumps shrink when menstruation is over. Hormonal disorders may, rarely, cause galactorrhoea (abnormal milk production). In men, gynaecomastia may result from hormonal disturbance or treatment with certain drugs.... breast, disorders of the

Breast Lump

Any mass, swelling, or cyst that can be felt in the breast tissue.

At least 90 per cent of lumps are noncancerous; the rest are breast cancer.

Many women have generally lumpy breasts, with the lumps more obvious in the days before a period.

Once known as fibrocystic disease or fibroadenosis, this is now considered to be a variation of normal.

Lumpy breasts do not increase the risk of developing breast cancer.

However, any new, distinct, or separate lump should be assessed by a doctor.

In a young woman, a single lump is most likely to be a fibroadenoma.

This noncancerous growth is usually round, firm, and rubbery, causes no pain, and can be moved about beneath the skin using the fingertips.

In an older woman, a lump is more likely to be a noncancerous, fluid-filled breast cyst.

Regular breast self-examination may detect any changes.

Treatment depends on the cause and type of lump.

Cysts can be drained in a simple outpatient procedure.

Other lumps can be removed surgically.... breast lump

Breast Self-examination

Visual and manual examination of the breasts carried out by a woman to detect lumps

and other changes that might be an indication of early breast cancer. To carry out self-examination, the breasts should be checked in a mirror for any dimpling of the skin or changes in the nipples or breast size and shape. Then, with one arm behind the head, and using small circular movements, the breast should be gently but firmly pressed. The entire breast, armpit area, and nipple should be examined. Regular self-examination helps a woman to become familiar with the appearance and feel of her breasts; any changes should be reported to a doctor without delay.... breast self-examination

Breast Tenderness

Soreness or tenderness of the breasts, often with a feeling of fullness. Breast tenderness is an extremely common problem. In most women it is cyclical, varying in severity in response to the hormonal changes of the menstrual cycle. It is usually most severe before a period (see premenstrual syndrome). It tends to affect both breasts and may be aggravated by stress or caffeine in drinks. Breast tenderness can also be noncyclical and may be caused by muscle strain or mastitis. During lactation, it may be due to engorgement with milk. Rarely, tenderness may be due to a breast cyst or breast cancer. However, examination by a doctor will exclude any underlying problems. Women with large breasts are more likely to suffer from both cyclical and noncyclical breast tenderness.

Cyclical tenderness may be relieved by reduced caffeine intake, relaxation

exercises for stress, a well-fitting bra, or weight loss to reduce breast size.

If these measures do not work, hormonal treatment may be recommended.... breast tenderness

Auditory Brainstem Implant

a device similar to a *cochlear implant except that the electrode stimulates the auditory parts of the *brainstem rather than the cochlea. It is used to restore hearing of profoundly deaf people who have had damage to both auditory nerves and are hence unsuitable for cochlear implantation. It consists of an electrode that is permanently implanted on the surface of the brainstem. An external device with a microphone and an electronic processing unit pass information to the electrode using radio-frequency waves. The implant is powered by batteries in the external part of the device. It is most commonly used in patients with *neurofibromatosis type II who have had bilateral *vestibular schwannomas.... auditory brainstem implant
