Visuals of the Breast Lymph Nodes and Hormones

Each breast also contains blood vessels, as well as vessels that carry a fluid called lymph. Lymph travels throughout the body through a network called the lymphatic system, carrying cells that help the body fight infections. The lymph vessels lead to the lymph nodes (small, bean-shaped glands).

One group of lymph nodes is located in the armpits, above the collarbone and in the chest. If breast cancer has reached these nodes, it may mean that cancer cells have spread to other parts of the body via the lymphatic system. Lymph nodes are also found in many other parts of the body.

Breast development and function depend on the hormones estrogen and progesterone, which are produced in the ovaries. Estrogen elongates the ducts and causes them to create side branches. Progesterone increases the number and size of the lobules in order to prepare the breast for nourishing a baby.

After ovulation, progesterone makes the breast cells grow and blood vessels enlarge and fill with blood. At this time, the breasts often become engorged with fluid and may be tender and swollen.

As You Journey through Menopause, Vivelle-Dot Is By Your Side

VIVELLE-DOT (estradiol transdermal system) IS AVAILABLE BY PRESCRPTION ONLY.

INDICATION

Vivelle-Dot is used after menopause to: reduce moderate to severe hot flashes; treat moderate to severe dryness, itching and burning in or around the vagina; help reduce your chances of getting osteoporosis (thin weak bones); and treat certain conditions in which a young woman's ovaries do not produce enough estrogens naturally. Vivelle-Dot 0.025 mg/day is only used to prevent osteoporosis from menopause. If you use Vivelle-Dot only to treat your dryness, itching, and burning in and around your vagina or if you use Vivelle-Dot only to prevent osteoporosis from menopause, talk with your healthcare professional about whether a different treatment or medicine without estrogens might be better for you.

IMPORTANT SAFETY INFORMATION

Estrogens increase the chances of getting cancer of the uterus (womb). Report any unusual vaginal bleeding right away while you are taking estrogens. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb).

Do not use estrogens with or without progestins to prevent heart disease, heart attacks, or strokes. Using estrogens with or without progestins may increase your chances of getting heart attacks, strokes, breast cancer, and blood clots. Using estrogens with progestins may increase your risk of dementia (decline in memory and thinking skills).

Vivelle-Dot should not be used if you have unusual vaginal bleeding; currently have or have had certain cancers, including cancer of the breast or uterus; had a stroke or heart attack in the recent past (for example, in the past year); currently have or have had blood clots; currently have or have had liver problems; or think you may be, or know that you are, pregnant.

The most common side effects that may occur with Vivelle-Dot are headache, breast tenderness, and back pain.

You and your healthcare professional should talk regularly about whether you still need treatment with Vivelle-Dot.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
