Ablation: Removal or excision. Ablation is usually carried out surgically. For example, surgical removal of the thyroid gland (a total thyroidectomy) is ablation of the thyroid. The word ablation comes from the Latin ablatum meaning to carry away.

Abnormal: Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).

Anesthesia: Loss of feeling or awareness. A general anesthetic puts the person to sleep. A local anesthetic causes loss of feeling in a part of the body such as a tooth or an area of skin without affecting consciousness. Regional anesthesia numbs a larger part of the body such as a leg or arm, also without affecting consciousness. The term "conduction anesthesia" encompasses both local and regional anesthetic techniques. Many surgical procedures can be done with conduction anesthesia without significant pain. In many situations, such as a C-section, conduction anesthesia is safer and therefore preferable to general anesthesia. However, there are also many types of surgery in which general anesthesia is clearly appropriate.

Benign: Not cancer. Not malignant. A benign tumor does not invade surrounding tissue or spread to other parts of the body. A benign tumor may grow but it stays put (in the same place).

Biopsy: The removal of a sample of tissue for purposes of diagnosis. (Many definitions of "biopsy" stipulate that the sample of tissue is removed for examination under a microscope. This may or may not be the case. The diagnosis may be achieved by other means such as by analysis of chromosomes or genes.)
See the entire definition of Biopsy

Cancer: An abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread).
See the entire definition of Cancer

Cervical: Having to do with any kind of neck including the neck on which the head is perched and the neck of the uterus. The word "cervix" in Latin means "neck". That is why cervical vertebrae and cervical cancer involve quite disparate parts of the anatomy joined only by the meaning of the word "cervix".

Cervix: The cervix is the lower, narrow part of the uterus (womb). The uterus, a hollow, pear-shaped organ, is located in a woman's lower abdomen, between the bladder and the rectum. The cervix forms a canal that opens into the vagina, which leads to the outside of the body.

Dilate: To stretch or enlarge. It comes from the Latin verb "dilatare" meaning "to enlarge or expand."

Discharge: 1.The flow of fluid from part of the body, such as from the nose or vagina.
2. The passing of an action potential, such as through a nerve or muscle fiber.
3. The release of a patient from a course of care. The doctor may then dictate a discharge summary.

Edema: The swelling of soft tissues as a result of excess water accumulation.
See the entire definition of Edema

Endometrial ablation: Removal of the lining of the womb. Removing the uterine lining decreases menstrual flow or stops it completely.
See the entire definition of Endometrial ablation

Endometrium: The uterine lining; the cells that line the uterus (the womb); the inner layer of the uterus. This tissue is shed monthly in response to the hormonal changes of the menstrual period. The endometrium then grows back and slowly gets thicker and thicker until the next period when it is once again sloughed off.

Fibroid: A benign tumor of the uterus and the single most common indication for hysterectomy. Fibroids can be present and be inapparent. However, they are clinically apparent in up to 25% of women and cause significant morbidity, including prolonged or heavy menstrual bleeding, pelvic pressure or pain, and, in rare cases, reproductive dysfunction. Both the economic cost and the effect of fibroids on quality of life are substantial.
See the entire definition of Fibroid

Fibroids: Fibroids are common, benign tumors of smooth muscle in the uterus (womb). Uterine fibroids are the most common reason for performing a hysterectomy. Fibroids do not produce symptoms in all women, but may lead to prolonged or heavy menstrual bleeding, pelvic pressure or pain, and rarely to infertility. In addition to hysterectomy, less invasive surgical procedures have been employed to remove uterine fibroids. Fibroids can be detected by radiologic testing, such as ultrasound, CAT scan, or magnetic resonance imaging (MRI).

Genital: Pertaining to the external and internal organs of reproduction. (Not to be confused with genetic.)

Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.
See the entire definition of Hormone

Hormone therapy: A form of treatment that takes advantage of the fact that certain cancers depend on hormones to grow. Hormone therapy may include giving hormones to the patient or decreasing the level of hormones in the body.

Hysterectomy: A surgical operation to remove the uterus and, sometimes, the cervix. Removal of the entire uterus and the cervix is referred to as a total hysterectomy. Removal of the body of the uterus without removing the cervix is referred to as a subtotal hysterectomy.
See the entire definition of Hysterectomy

Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person.

Lungs: The lungs are a pair of breathing organs located with the chest which remove carbon dioxide from and bring oxygen to the blood. There is a right and left lung.

Menstrual: Pertaining to menstruation (the menses), as in last menstrual period, menstrual cramps, menstrual cycle, and premenstrual syndrome. From the Latin menstrualis, from mensis meaning month.

Menstrual cramps: Cramping in the lower abdomen, usually in the first or second day of the menstrual cycle. These are caused contractions of the uterus as it expels its unneeded contents, and also by the passage of clotted blood through the cervix. Ibuprofen or other pain relievers can reduce the severity of cramps; some women report that exercise is also helpful. Severe menstrual cramps, particularly if paired with excessive bleeding or passage of large blood clots, can occasionally be a sign of endometriosis or other disorders of the female reproductive tract. Also known as dysmenorrhea.

Nausea: Nausea, is the urge to vomit. It can be brought by many causes including, systemic illnesses, such as influenza, medications, pain, and inner ear disease. When nausea and/or vomiting are persistent, or when they are accompanied by other severe symptoms such as abdominal pain, jaundice, fever, or bleeding, a physician should be consulted.

OB/GYN: A commonly used abbreviation. OB is short for obstetrics or for an obstetrician, a physician who delivers babies. GYN is short for gynecology or for a gynecologist, a physician who specializes in treating diseases of the female reproductive organs. The word "gynecology" comes from the Greek gyno, gynaikos meaning woman + logia meaning study, so gynecology literally is the study of women. These days gynecology is focused largely on disorders of the female reproductive organs. An obstetrician/gynecologist (OB/GYN) is therefore a physician who both delivers babies and treats diseases of the female reproductive organs.

Operating room: A facility equipped for performing surgery. Abbreviated OR.

Outpatient: A patient who is not an inpatient (not hospitalized) but instead is cared for elsewhere -- as in a doctor's office, clinic, or day surgery center. The term outpatient dates back at least to 1715. Outpatient care today is also called ambulatory care.

Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia. Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.

Pregnancy: The state of carrying a developing embryo or fetus within the female body. This condition can be indicated by positive results on an over-the-counter urine test, and confirmed through a blood test, ultrasound, detection of fetal heartbeat, or an X-ray. Pregnancy lasts for about nine months, measured from the date of the woman's last menstrual period (LMP). It is conventionally divided into three trimesters, each roughly three months long.

Probe: (1) In surgery, a probe is a slender flexible rod with a blunt end used to explore, for example, an opening to see where it goes. (2) In molecular genetics, a probe is a labeled bit of DNA or RNA used to find its complementary sequence or locate a particular clone like homing in on a needle in a haystack.

Pulmonary: Having to do with the lungs. (The word comes from the Latin pulmo for lung).

Pulmonary edema: Fluid in the lungs.

Recurrence: The return of a sign, symptom or disease after a remission. The reappearance of cancer cells at the same site or in another location is, unfortunately, a familiar form of recurrence.
See the entire definition of Recurrence

Recurrent: Back again. A recurrent fever is a fever that has returned after an intermission: a recrudescent fever.

Resolution: In genetics, resolution refers to the degree of molecular detail on a physical map of DNA, ranging from low to high.

Superficial: In anatomy, on the surface or shallow. As opposed to deep. The skin is superficial to the muscles. The cornea is on the superficial surface of the eye.

Surgeon: A physician who treats disease, injury, or deformity by operative or manual methods. A medical doctor specialized in the removal of organs, masses and tumors and in doing other procedures using a knife (scalpel). The definition of a "surgeon" has begun to blur in recent years as surgeons have begun to minimize the cutting, employ new technologies that are "minimally invasive," use scopes, etc.
See the entire definition of Surgeon

Surgery: The word "surgery" has multiple meanings. It is the branch of medicine concerned with diseases and conditions which require or are amenable to operative procedures. Surgery is the work done by a surgeon. By analogy, the work of an editor wielding his pen as a scalpel is s form of surgery. A surgery in England (and some other countries) is a physician's or dentist's office.

Uterine bleeding: See: Menstruation. See also Menometrorrhagia; Menorrhagia; Metrorrhagia.

Uterine lining: The inner layer of the uterus (womb); the cells that line the womb; anatomically termed the endometrium.

Uterus: The uterus (womb) is a hollow, pear-shaped organ located in a woman's lower abdomen between the bladder and the rectum. The narrow, lower portion of the uterus is the cervix; the broader, upper part is the corpus. The corpus is made up of two layers of tissue.

Vaginal discharge: Vaginal discharge is a fluid produced by glands in the vaginal wall and cervix that drains from the opening of the vagina. The amount and appearance of normal vaginal discharge varies throughout the menstrual cycle. An increase in the amount of vaginal discharge, an abnormal odor or consistency of the fluid, or pain that accompanies vaginal discharge can all be signs of infection or other disorders. Such disorders include (this is not an all inclusive list) bacterial vaginosis, yeast vaginitis, and vaginitis.
