Other types of cysts are much less common. Your ovaries normally grow cyst-like structures called follicles each month. Follicles produce the hormones estrogen and progesterone and release an egg when you ovulate.
If a normal monthly follicle keeps growing, it's known as a functional cyst. There are two types of functional cysts:. Functional cysts are usually harmless, rarely cause pain, and often disappear on their own within two or three menstrual cycles. Dermoid cysts and cystadenomas can become large, causing the ovary to move out of position. This increases the chance of painful twisting of your ovary, called ovarian torsion.
Ovarian torsion may also result in decreasing or stopping blood flow to the ovary. Ovulation is the release of an egg from one of the ovaries. It often happens about midway through the menstrual cycle, although the exact timing may vary. In preparation for ovulation, the lining of the uterus, or endometrium, thickens. The pituitary gland in the brain stimulates one of the ovaries to release an egg.
The wall of the ovarian follicle ruptures at the surface of the ovary. The egg is released. Finger-like structures called fimbriae sweep the egg into the neighboring fallopian tube. The egg travels through the fallopian tube, propelled in part by contractions in the fallopian tube walls. Here in the fallopian tube, the egg may be fertilized by a sperm.
If the egg is fertilized, the egg and sperm unite to form a one-celled entity called a zygote. Most cysts form as a result of some type of blockage at the site of where a gland appears on the body. This can be a salivary gland or even a hair follicle, and the cyst can vary in size from very tiny to the size of a large ball. They are most noticeable when they form under the skin and create a protrusion or feel like a lump. Cysts are most commonly caused by blockage in a duct, which can be due to trauma, infection, or even an inherited tendency.
The type of cyst depends on where it forms — some cysts can be internal such as in a breast, the ovaries, or the kidneys while others are external and form in visible locations on the body.
Activities like gymnastics, which place large amounts of stress on the wrist, can cause ganglion cysts to form.
Ganglion cysts form on a joint — typically on the wrist or ankle — and form a large, visible lump which is filled with a thick, viscous liquid. Whenever we have a new lump, bump, or an unusual mass, it can be easy to assume the worst—cancer. But oftentimes the diagnosis is a benign cyst or tumor.
The following seven points can help you understand some key facts about cysts and tumors, including how they differ, how they develop, and how they are treated. A tumor is usually a solid mass of tissue. Normally, the body grows new cells as needed. When old cells die, new ones form to take their place. They range in size from tiny to very large. Some develop because of infections, blockages in ducts, or even damaged hair follicles.
