Options for women at high risk of breast cancer from atypical hyperplasia may include: Seeing a health care provider more often (such as every 6 to 12 months) for a breast exam along with the yearly mammogram. Additional imaging with breast MRIs may also be recommended.
What are the treatment options for atypical hyperplasia of the breast?
Learning of any abnormality in your breast is concerning, but remember that atypical lobular hyperplasia is not cancer. It does, however, mean that prevention strategies are perhaps more important to you now than ever. Take control of your condition by doing all that you can to affect modifiable risk factors.
What can I do about atypical lobular hyperplasia?
Among women with atypical lobular hyperplasia in whom cancer developed, 77% of the cancers were ductal and 23% were lobular or other histologic types. Among the 95 women with invasive breast cancer and known nodal status, 75% had node-negative cancer, and 25% had node-positive cancer.
What is the prevalence of atypical lobular hyperplasia in breast cancer?
What kind of follow-up care is needed after a diagnosis of atypical hyperplasia? Surgery is usually performed to remove the entire area of tissue where the atypical cells were found. In up to 20% of cases, cancer may be found after a final exam of the removed breast tissue. After surgery, increased screening is recommended.
What kind of follow-up care is needed After a diagnosis of atypical hyperplasia?
How serious is atypical lobular hyperplasia?
Atypical hyperplasia isn't cancer, but it increases the risk of breast cancer. Over the course of your lifetime, if the atypical hyperplasia cells accumulate in the milk ducts or lobules and become more abnormal, this can transition into noninvasive breast cancer (carcinoma in situ) or invasive breast cancer.
Is atypical lobular hyperplasia reversible?
Lobular means that the unusual cells are in the lobules, the parts of the breast capable of making milk. Atypia and hyperplasia are thought to be reversible, although it isn't clear what can nudge them back to normal.
How often does ALH turn into cancer?
The lifetime risk of developing breast cancer in patients with ADH or ALH on biopsy is 15% to 20%.
Does ALH need to be excised?
Conclusions: Surgical excision is indicated for all PCBs diagnosed as ALH or LCIS, as a significant percentage will show carcinoma at excision.
Is surgery necessary for atypical lobular hyperplasia?
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.
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.
Is ALH serious?
Both LCIS and ALH are non-cancerous breast conditions, but are linked to a higher risk of invasive breast cancer later in life.
Is atypical lobular hyperplasia precancerous?
Atypical hyperplasia (or atypia) means that there are abnormal cells in breast tissue taken during a biopsy. (A biopsy means that tissue was removed from the body for examination in a laboratory.) These abnormal cell collections are benign (not cancer), but are high-risk for cancer.
Is ALH a precancer?
Not to be confused with breast cancer, ALH is an overgrowth of unusual-looking cells in the lobes of the breast, specifically in the epithelial cells lining the lobes. It is however, a precancerous condition that should be monitored by a breast specialist.
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.
What is the difference between ALH and LCIS?
According to the criteria proposed by Page, LCIS was diagnosed if 50% or more of a TDLU's ducts were involved, and ALH was diagnosed if the discohesive monotonous proliferation of cells occupied less than 50% of a TDLU or if only pagetoid extension a duct by these cells was noted 13 (Fig.
Is ALH the same as LCIS?
LCIS and a condition called atypical lobular hyperplasia (ALH) are both considered lobular neoplasia. In-situ carcinoma with duct and lobular features means that the in-situ carcinoma looks like DCIS in some ways and LCIS in some ways (when seen under the microscope), so the pathologist can't call it one or the other.
How much does lobular hyperplasia increase risk of breast cancer?
While having atypical lobular hyperplasia increases one's lifetime risk of breast cancer by up to 2%, prevention methods have been found to reduce that risk by up to 70% in women with ALH or other high-risk breast conditions.
What is abnormal lobular hyperplasia?
The pattern of growth seen in atypical lobular hyperplasia is abnormal and may contain cells that are characteristic of lobular carcinoma in situ (LCIS)—an overgrowth of cells in the lobules.
Why do you need close monitoring for ALH?
Because your risk of breast cancer is higher than average if you have ALH, you will need close monitoring. 1 . ALH is similar to atypical ductal hyperplasia (ADH), which causes more cells to develop in the lining of the breast ducts (milk producing glands).
What is ALH on a mammogram?
Mammogram: ALH appears as a cluster of microcalcifications on a mammogram. Ultrasound: A breast ultrasound uses sound waves to reveal groups of microcalcifications. Breast biopsy: A breast biopsy is the most definitive method for diagnosis of ALH.
Can lobular hyperplasia affect men?
An exact cause of atypical lobular hyperplasia is unknown. Doctors believe it is a natural part of breast changes for some women as they get older. It often affects women over 35, but it can affect women regardless of age. It may also affect men but is very rare. 3 .
Can lobular hyperplasia cause breast cancer?
Atypical lobular hyperplasia typically doesn't cause any notable symptoms, though it may cause breast pain in some cases. Most women are unaware of the condition until they get the results of routine breast imaging. 2 . That said, since atypical lobular hyperplasia can lead to breast cancer, make sure you bring any abnormalities you notice ...
Is lobular hyperplasia a precancerous disease?
Diagnosis. Treatment. Atypical lobular hyperplasia (ALH) occurs in the epithelial cells lining the lobes of the breast. Instead of one even layer of uniformly shaped cells, overgrowth yields several layers, with some cells being irregular in shape and size. Atypical lobular hyperplasia is not breast cancer, but it is considered a precancerous ...

These medications block estrogen and help decrease the risk of estrogen receptor-positive invasive breast cancer. The effects can remain for up to 15 years after taking them.
What is the best medication for menopause?
Tamoxifen (Nolvadex®) is recommended for women who aren’t yet in menopause. Other drugs are recommended for women in menopause. Menopause is defined as the absence of your menstrual period for 12 months. The medications for menopausal women are: 1 Raloxifene (Evista®). 2 Exemestane (Aromasin®). 3 Anastrozole (Arimidex®).
Does atypical hyperplasia mean cancer?
If your breast biopsy shows atypical hyperplasia, this doesn’t mean that you have cancer. The cells are a marker for increased breast cancer risk. Studies have shown that women with atypical hyperplasia have up to a four times increase in breast cancer risk. This is especially true for estrogen receptor-positive breast cancer.
What is the difference between lobular and ductal hyperplasia?
Ductal hyperplasia (also called duct epithelial hyperplasia) is an overgrowth of the cells that line the small tubes (ducts) inside the breast, while lobular hyperplasia is an overgrowth of cell lining the milk glands (lobules). Ductal and lobular hyperplasia occur at about the same rate, and have about the same effect on breast cancer risk.
What is the term for the overgrowth of the ducts in the breast?
Hyperplasia of the Breast (Ductal or Lobular) Hyperplasia is also known as epithelial hyperplasia or proliferative breast disease. It’s an overgrowth of the cells that line the ducts or the milk glands (lobules) inside the breast. Ductal hyperplasia (also called duct epithelial hyperplasia) is an overgrowth of the cells that line the small tubes ...
Is hyperplasia normal or atypical?
Hyperplasia is often described as either usual or atypical based on how the cells look under a microscope. In usual hyperplasia, the cells look very close to normal. In atypical hyperplasia (or hyperplasia with atypia), the cells are more distorted. This can be either atypical ductal hyperplasia (ADH) or atypical lobular hyperplasia (ALH).
Is atypical hyperplasia a risk factor for breast cancer?
Atypical hyperplasia (ADH or ALH) is linked to a higher risk of breast cancer. Even though most women with atypical hyperplasia will not develop breast cancer, it's still important to talk with a health care provider about your risk and what, if any, options are best for you.
Does hyperplasia increase the risk of breast cancer?
Hyperplasia can affect your risk for breast cancer, but how much depends on what type it is: Mild hyperplasia of the usual type: This does not increase the risk for breast cancer. Moderate or florid hyperplasia of the usual type (without atypia), also known as usual hyperplasia: The risk of breast cancer is about 1½ to 2 times that ...
Can hyperplasia be felt?
Hyperplasia doesn’t usually cause a lump that can be felt, but it can cause changes that can be seen on a mammogram. It’s diagnosed by doing a biopsy. (A hollow needle may be used to remove a small piece of tissue that’s checked in the lab. Or, surgery may be done to take out the abnormal breast tissue.)
Can you get atypical hyperplasia removed?
Most types of usual hyperplasia do not need to be treated. But if atypical hyperplasia (ADH or ALH) is found on a needle biopsy, more breast tissue around it might be removed with surgery to be sure that there is nothing more serious nearby, such as cancer. (This is more likely to be recommended for ADH than for ALH.)
What is the risk of breast cancer in atypical hyperplasia?
The risk of breast cancer in those with atypical hyperplasia is about four times higher than in those who don't have hyperplasia. The risk is similar for atypical ductal hyperplasia ...

How many women will not develop breast cancer?
And 87 will not develop breast cancer. At 25 years after diagnosis, about 30% of women with atypical hyperplasia may develop breast cancer. Put another way, for every 100 women diagnosed with atypical hyperplasia, 30 can be expected to develop breast cancer 25 years after diagnosis. And 70 will not develop breast cancer.
What is atypical ductal hyperplasia?
Atypical ductal hyperplasia describes abnormal cells within the breast ducts. Atypical lobular hyperplasia describes abnormal cells within the breast lobules. Atypical hyperplasia is thought to be part of the complex transition of cells that may accumulate and evolve into breast cancer.
How many lobes are there in breast milk?
Each breast contains 15 to 20 lobes of glandular tissue, arranged like the petals of a daisy. The lobes are further divided into smaller lobules that produce milk for breastfeeding. Small tubes (ducts) conduct the milk to a reservoir that lies just beneath your nipple.
Is atypical hyperplasia a cancer?
Atypical hyperplasia isn't cancer, but it increases the risk of breast cancer. Over the course of your lifetime, if the atypical hyperplasia cells accumulate in the milk ducts or lobules and become more abnormal, this can transition into noninvasive breast cancer (carcinoma in situ) or invasive breast cancer.
What You Need to Know
If tests confirm you have atypical ductal hyperplasia in one or both of your breasts, your doctor will want to follow your breast health very carefully.
What is atypical ductal hyperplasia?
To better understand the pathophysiology, imagine looking through a normal duct in the breast like a hollow tube. In a normal and healthy duct, you see uniform and orderly cells growing next to each other in a single layer lining the inside of the duct.
Symptoms of Atypical Ductal Hyperplasia
There are no symptoms specific to ADH. The condition might be discovered when you are being seen or tested for a problem with your breast such as pain, a lump or discharge.
How is atypical ductal hyperplasia diagnosed?
A breast biopsy, which is usually done to evaluate an abnormality seen on imaging or during a physical exam, can reveal atypical ductal hyperplasia.
What is the treatment for atypical ductal hyperplasia?
After the excisional biopsy, close breast surveillance is usually recommended. Finding a provider who specializes in breast health is important to ensure you are getting the appropriate follow-up care. In addition, there are risk-reducing strategies that your breast care specialist will discuss with you.
Will I get breast cancer if I have ADH?
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.
How much is atypical lobular hyperplasia risk?
For patients with atypical hyperplasia, the guidelines state that there is insufficient evidence to make recommendations for or against MRI screening; however, they cite a lifetime risk of only 10 to 20% among women with atypical lobular hyperplasia.
Why is atypical hyperplasia the most important breast cancer diagnosis?
Because of the high-risk features and high incidence of atypical hyperplasia and the availability of effective breast-cancer prevention strategies, atypical hyperplasia is the benign breast diagnosis that is most important to act on clinically.
How many women have invasive breast cancer?
Among the 95 women with invasive breast cancer and known nodal status, 75% had node-negative cancer, and 25% had node-positive cancer. A total of 88% of the breast cancers were estrogen receptor–positive. The cumulative incidence of breast cancer appeared to increase linearly over time ( Figure 2 ).
Why do we do breast biopsies?
Breast biopsies are commonly performed to evaluate mammographic or palpable findings that are of concern, and the majority reveal benign findings. More than 1 million of the breast biopsies that are performed annually in the United States are found to be benign. 1 On the basis of the histologic findings, it is possible to stratify women ...
Can atypical hyperplasia cause death?
Another important issue for women with atypical hyperplasia concerns their risk of death from breast cancer versus their risk of death from other causes. In fact, breast cancer will not develop in the majority of these women.
What is atypical hyperplasia of the breast?
Atypical hyperplasia of the breast refers to abnormal epithelial proliferative breast lesions that are not qualitatively or quantitatively abnormal enough to be classified as carcinoma in situ. These lesions can occur in male and female breast tissue, but they are rare, incidental findings in male gynecomastia specimens.
What is ADH in breast cancer?
Atypical lobular hyperplasia (ALH), like ADH, is another high-risk breast lesion that has been associated with a four-fold to five-fold increased lifetime risk of developing breast cancer in either the ipsilateral or contralateral breast.
Is ADH a pre-malignant lesion?
Both of these lesions are considered pre-malignant or high-risk lesions for the development of more advanced neoplasia. 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 ...
