What is hyperplasia of the breast?

Hyperplasia is an overgrowth of the cells that line the lobules (milk-producing glands) or ducts (small tubes) inside the breast. It is not cancer, but some types of hyperplasia are linked with a higher risk of developing breast cancer (see below).

What causes hyperplasia in the breast?

The process begins when normal cell development and growth become disrupted, causing an overproduction of normal-looking cells (hyperplasia). Atypical hyperplasia. The excess cells stack upon one another and begin to take on an abnormal appearance. Noninvasive (in situ) cancer.

Does hyperplasia mean cancer?

An increase in the number of cells in an organ or tissue. These cells appear normal under a microscope. They are not cancer, but may become cancer.

How do you fix hyperplasia of the breast?

Atypical hyperplasia is generally treated with surgery to remove the abnormal cells and to make sure no in situ or invasive cancer also is present in the area. Doctors often recommend more-intensive screening for breast cancer and medications to reduce your breast cancer risk.

How common is breast hyperplasia?

Atypical ductal hyperplasia (ADH) is a relatively common lesion reported to be found in about 5% to 20% of breast biopsies. Although not carcinoma, it is classified as a high-risk precursor lesion due to its association with and potential to progress to ductal carcinoma in situ (DCIS) as well as invasive carcinoma.

Histopathology Breast--Epithelial hyperplasia

How serious are precancerous cells in breast?

Ductal carcinoma in situ (DCIS) is when abnormal cells appear in the breast ducts. The words in situ mean “in the original place.” It's possible for the cells to turn into invasive cancer, meaning they spread into healthy tissue. That's why you should get treatment right away.

Is hyperplasia reversible?

Hyperplasia, metaplasia, and dysplasia are reversible because they are results of a stimulus. Neoplasia is irreversible because it is autonomous.

Can atypical ductal hyperplasia go away?

Atypia and hyperplasia are thought to be reversible, although it isn't clear what can nudge them back to normal. Atypical ductal hyperplasia (ADH) increases your risk of breast cancer occurring in the breast where the ADH was found.

Should I take tamoxifen for atypical ductal hyperplasia?

A woman who has been diagnosed with any type of uterine cancer or atypical hyperplasia of the uterus (a kind of pre-cancer) should not take tamoxifen to help lower breast cancer risk. Raloxifene has not been tested in pre-menopausal women, so it should only be used if you have gone through menopause.

Should ADH be removed?

If ADH is found on needle biopsy, more tissue in that area usually needs to be removed to be sure that nothing more serious is also present in the breast. The tissue that is removed is looked at under the microscope, and if nothing more serious is found, no other treatment is needed.

How long does it take for hyperplasia to turn into cancer?

In one study, hyperplasia without atypia progressed to endometrial carcinoma in fewer than 5% of women; in comparison, atypical hyperplasia progressed to endometrial carcinoma in one in eight women within 10 years, and in one in three women within 20 years.

What are the symptoms of hyperplasia?

How often does atypical ductal hyperplasia turn into cancer?

If you've been diagnosed with ADH, you have an increased risk of developing breast cancer in the future. Specifically, at five years after the diagnosis of ADH, 7% of women will develop breast cancer, and at 10 years post-diagnosis, 13% of these women will develop breast cancer.

What is the next step after a positive breast biopsy?

After the biopsy procedure, the breast tissue is sent to a lab, where a doctor who specializes in analyzing blood and body tissue (pathologist) examines the sample using a microscope and special procedures. The pathologist prepares a pathology report that is sent to your doctor, who will share the results with you.

Should I be worried if I need a breast biopsy?

A biopsy is only recommended if there's a suspicious finding on a mammogram, ultrasound or MRI, or a concerning clinical finding. If a scan is normal and there are no worrisome symptoms, there's no need for a biopsy. If you do need a biopsy, your doctor should discuss which type of biopsy is needed and why.

What happens if my breast biopsy is abnormal?

Abnormal cells found during a breast biopsy have a high risk of becoming cancerous. The younger a woman is when she is diagnosed with atypical hyperplasia, the more likely she is to develop breast cancer later in life.

Why you should not take tamoxifen?

Tamoxifen may cause hot flashes and increase the risk of blood clots and stroke. Aromatase inhibitors may cause muscle and joint aches and pains. Less common but more severe side effects of aromatase inhibitors are heart problems, osteoporosis, and broken bones.

What are the long term side effects of tamoxifen?

Tamoxifen can have side effects, including hot flashes, fatigue, and an increased risk of blood clots and endometrial cancer. But there was no substantial increase in serious side effects, including endometrial cancer incidence or death, in women who took tamoxifen for the longer period, Gray reported.

When does atypical ductal hyperplasia require surgical excision?

Currently, the recommendation for diagnosis of ADH on core needle biopsy is surgical excision, because approximately 20% to 30% of these lesions are upgraded to cancer.

What does usual ductal hyperplasia Mean?

In usual ductal hyperplasia, there is an overgrowth of cells lining the ducts in the breast, but the cells look very close to normal. In atypical hyperplasia (or hyperplasia with atypia), the cells look more distorted and abnormal.

How long do you have to stay in hospital after a lumpectomy?

Many people go home on the same day as their operation. Others are in hospital for about 2 to 7 days. The length of your stay depends on the type of operation you have and your recovery.

How long after a breast biopsy do you get the results?

Getting a biopsy can be a stressful event and you won't get your breast biopsy results right away. The samples must be sent to a lab where a pathologist can analyze them. The report will then go to the doctor who ordered it. Most of the time, this takes at least a day or two, but can take a week or two.

What happens during hyperplasia?

Endometrial hyperplasia thickens the uterus lining, causing heavy or abnormal bleeding. Atypical endometrial hyperplasia raises the risk of endometrial cancer and uterine cancer. The condition tends to occur during or after menopause.

What's the difference between benign and malignant?

A benign tumor has distinct, smooth, regular borders. A malignant tumor has irregular borders and grows faster than a benign tumor. A malignant tumor can also spread to other parts of your body. A benign tumor can become quite large, but it will not invade nearby tissue or spread to other parts of your body.
