According to the American Institute for Cancer Research, 38% of breast cancer cases in the US could be prevented if women ate a more healthful diet, got regular physical activity, and kept their weight under control.

The following press release from the University of Michigan on Medical News Today describes the growing trend of women choosing to have both breasts removed when a single mastectomy is all that is needed:
When Treatment Goes Too Far
Recent research has shown that more women are choosing to have their healthy breast removed after being diagnosed with breast cancer. The number of double mastectomies from 1998 to 2003 more than doubled, according to one study.
But this additional surgery has little impact on long-term survival or whether the cancer will recur, says Lisa Newman, M.D., M.P.H., director of the Breast Care Clinic at the U-M Comprehensive Cancer Center.
“Women are choosing to have more radical surgery than is necessary because of fear that their cancer will come back. Bilateral (double) mastectomy will decrease the possible need for future breast surgery, but it has little or no impact on the overall survival of a woman who has already been diagnosed with a single breast cancer,” Newman says.
For women who test positive for the BRCA1 or BRCA2 gene mutations such as actress Christina Applegate opting for a double mastectomy may make sense. The risk of developing breast cancer in the other breast is 30 percent. But women without the BRCA mutation do not face a higher risk of breast cancer in the unaffected breast.
“Women have the opportunity to choose the treatment that feels right for them. But over-treating breast cancer by removing a healthy breast is unnecessary,” Newman says.
Women sometimes choose to have both breasts removed when a single mastectomy is recommended as treatment for breast cancer or ductal carcinoma in situ (DCIS). Some do it because they don’t want to face the possibility of the cancer returning, even though the risk of recurrence is low with invasive cancer and unlikely with DCIS. There is no survival advantage for women who choose to have the healthy breast removed.
Others may opt for prophylactic mastectomy of their healthy breast because their cosmetic surgeon suggests that the appearance of the breasts will be better if both are removed and reconstructed at the same time. It would seem that loosing the sensation of touch in a healthy breast would be too high a price to pay for a matching set.
Medical treatment is not the only avenue for reducing the likelihood that breast cancer will recur. Lifestyle choices can reduce breast cancer risk and recurrence.
A diagnosis of lobular carcinoma in situ (LCIS) or ductal carcinoma in situ (DCIS) is not as scary as it sounds. The Latin term “in situ” means in place. LCIS and DCIS can not spread outside the breast unless they undergo a transformation to become invasive cancer. That capacity for spreading, or metastasizing, is what makes invasive breast cancer dangerous.
The two types of carcinoma in situ are similar in that there are abnormal cells growing within the breast, but the similarities end there. LCIS develops in structures in the breast called lobules, which are the milk-producing glands, while DCIS develops in the ducts that carry milk from these glands.
LCIS serves as a warning sign that a woman is at risk for developing breast cancer, while DCIS is considered a very early stage of breast cancer. DCIS might more accurately be called a precancer, though, because it has no capacity to metastasize as invasive cancer does unless it first undergoes a change. It is thought that DCIS, if left untreated, would not become invasive in approximately half of the women who have it. There is no way to tell which will not progress, so its presence is taken seriously and it is treated as early cancer.
Depending on how extensive the DCIS is and what its characteristics are, it may be treated surgically with a lumpectomy or a mastectomy, and may require radiation. The risk of recurrence is very low.
The usual treatment for LCIS is not really treatment, but careful surveillance. Women get regular breast exams and a yearly mammogram. Thirty or forty years ago, LCIS was considered cancer and women would have a mastectomy after it was diagnosed. It was later determined that LCIS was simply a warning sign that breast cancer could develop in either breast. Both breasts have to be removed if risk is to be reduced, but prophylactic mastectomy for LCIS is considered “an overly aggressive approach” according to the National Cancer Institute.
Ideas about carcinoma in situ have changed over the years and are still changing. There is some uncertainty about the implications of having it for any particular woman. No one likes to be told they are high risk for breast cancer or that they have an early stage of the disease, but it is important to understand that there is a distinction between carcinoma in situ and invasive cancer so as not to take more drastic measures than are necessary.
Having a bilateral prophylactic mastectomy for either LCIS or DCIS is more than is needed unless there are additional risk factors like having a faulty BRCA gene or a very strong family history of breast cancer.
So why are women diagnosed with LCIS or DCIS told that prophylactic mastectomy is an option? Doctors are obligated to describe all options for treating a disease. With carcinoma in situ, it is important to understand that the most drastic treatment is not necessarily the best.
An article in the New York Times explains that for women with breast cancer to benefit from Tamoxifen therapy, they need a certain gene that allows them to convert the drug to a form that is active in the body. Tamoxifen is ineffective unless it can be converted to the active form. A gene test can be used to determine who will — and more important who will not — benefit from this drug.
Tamoxifen is not only used as a treatment for breast cancer. It is sometimes recommended as a preventive for premenopausal women who are at high risk for developing breast cancer. These otherwise healthy women should be tested for this gene before being exposed to the potential adverse effects of Tamoxifen, including menopausal symptoms, blood clots, and uterine cancer.
Using a medication that might have dangerous side effects as a preventive in healthy individuals would only be reasonable for those who have the potential to benefit. Better yet, breast cancer risk can be reduced by certain lifestyle choices. www.ReduceBreastCancerRisk.com
An article in the New York Times discusses the pros and cons of reconstruction options that are used after mastectomy. The article and the comments on it are a must-read for anyone considering prophylactic mastectomy.
It is very important for a woman considering prophylactic mastectomy to take her time and speak to all of her physicians about it. She needs advice not only from a cosmetic surgeon, but also from her breast surgeon and general practitioner in order to understand her true risk for breast cancer as well as the potential for long-term difficulties from reconstructive surgery. Having both breasts removed lowers the risk of getting breast cancer by 90%, but does not eliminate it. Each type of reconstruction has drawbacks that must be considered.
Whether a woman is getting a mastectomy as treatment for breast cancer or is having a prophylactic mastectomy in the hopes of preventing breast cancer, a second opinion from another cosmetic surgeon is a good idea. As the article points out, doctors may suggest one type of reconstruction over another because they are not skilled in other types, or they have a preference for a certain procedure. This may have more to do with the level of compensation for this particular procedure rather than with the well-being of the patient.
The National Institutes of Health has a list of designated cancer centers that is an excellent resource for finding a doctor for a second opinion.
Ann Romney recently reported that she was being treated for ductal carcinoma in situ (DCIS). The headlines read that she was being treated for breast cancer, but Mrs. Romney was very clear in her statement that DCIS is technically a precancer because it is not invasive.
DCIS is often referred to as an early stage of breast cancer, but there is an important distinction. DCIS differs from invasive cancer in that it stays in the breast ducts. It is the capacity to spread, or metastasize, that makes invasive breast cancer dangerous. The concern with DCIS – a noninvasive cancer — is that it can transform to become invasive breast cancer.
Scientists believe that DCIS would not always progress to breast cancer. Once detected, though, it is removed surgically to eliminate the possibility that it would become cancer because no one can predict which women would have it transform and which would not.
DCIS is a serious condition that requires treatment, but many women face greater anxiety than they should because it is referred to as an early stage of breast cancer. The implication is that it is the first of an inevitable series of stages. Instead, it is a precancerous lesion that could undergo a transformation to become invasive. The distinction is important, but it is often lost.
Depending on how extensive the DCIS is and what its characteristics are, it may be removed with a lumpectomy or a mastectomy and may require radiation. The risk of recurrence is very low.
There are sometimes stories in the news about women with DCIS choosing to have both breasts removed to prevent the possibility of getting breast cancer. Having a bilateral prophylactic mastectomy for DCIS is more than is needed, though it might be considered when a woman has additional risk factors like a faulty BRCA gene or a very strong family history of breast cancer.
Mrs. Romney’s health care providers deserve credit for being clear about what her diagnosis meant. Too many women who are diagnosed with DCIS do not realize that it has important differences from invasive breast cancer. With proper treatment and attention to lifestyle factors that reduce breast cancer risk, future problems are unlikely.
Ideas have changed in the 20 years since I was diagnosed with lobular carcinoma in situ (LCIS). My doctor advised me to have check-ups every three months and a yearly mammogram. She added that I would hear about another possibility for women with LCIS, but left no doubt that her recommendation was careful follow-up. She was firm enough that when I learned the alternative was double mastectomy, I gave it less consideration than I might otherwise have.
At the time, the medical community was evenly divided on whether to recommend careful follow-up for women with LCIS or a bilateral prophylactic mastectomy. (A single mastectomy is not an option because LCIS indicates a risk for breast cancer in both breasts.) These days it would be unusual for doctors to recommend a double mastectomy for a woman with LCIS and no other risk factors, but other options might be suggested. Tamoxifen is sometimes used for prevention in women who are high risk for breast cancer, and MRI’s may be used in addition to mammograms for screening. And, of course, a woman can reduce her risk for breast cancer with certain lifestyle changes.
So why, then, are there women with LCIS on message boards at several web sites agonizing over whether they should have bilateral prophylactic mastectomies?
The majority of women diagnosed with LCIS never get breast cancer. I have not — so far — and I did not have prophylactic mastectomy. I suspect women are told there are options without being told as clearly as I was that one of the choices is by far the most reasonable. When we hear there are various ways to treat a disease, we might assume the most drastic is the best. In this case it is not.
LCIS is not cancer, and it is not even considered a true precancer because if invasive cancer develops, it does not necessarily arise from the LCIS cells. LCIS is a warning sign that a woman is at risk for breast cancer. It sounds scarier than it is because it is called a carcinoma, or cancer. It got that label when it was first identified under a microscope years ago because the LCIS cells looked like cancer cells. The fact that there were important differences in their biological activity was learned later on.
The danger with invasive cancer is that it can spread outside the breast to other organs. LCIS does not have that capacity and remains in the breast. The phrase “in situ” is Latin for in place – and that is where LCIS stays.
There are some exceptions to favoring careful surveillance for women diagnosed with LCIS. Those who have a strong family history of breast cancer, those who have a defective form of the breast cancer gene, and those who have a type of LCIS called pleomorphic LCIS might take this warning more seriously and be advised to act more aggressively.
When the choice is not clear, however, it is wise to go for a second opinion. The best place would be one of the National Cancer Institute approved cancer centers. If there is not one nearby, look for a breast specialist by checking with a large hospital in your area. Friends, family, or your internist or gynecologist may be able to recommend a breast surgeon.
It might also be advisable to get a second opinion for the pathology report on tissue removed during biopsy. My doctor does this because there are sometimes difficulties identifying LCIS on pathology slides.
I thought my days were numbered. Adding to my concern was confusion about what this condition was and how it should be treated. Lobular carcinoma in situ (LCIS) is a cancer “in place” that has no potential for spreading outside the breast unless it undergoes transformation. It is classsified as a “Stage 0” breast cancer but is not a true cancer because it lacks the potential to metastasize, or spread.
Now there is more certainty about what women with LCIS should do, but when I was diagnosed almost twenty years ago, the medical community was evenly divided on what to recommend. Around half the doctors surveyed for a study at the time said they would carefully monitor women with LCIS with regular check-ups and mammograms. The other half said they would advise LCIS patients to have both breasts removed.
I considered the bilateral mastectomy, but followed the recommendation of my wise and progressive breast surgeon to have careful follow-up. Now most doctors favor this approach, though many mention prophylactic mastectomy as an option because they have an obligation to communicate all possible treatments to their patients. That doesn’t mean the most drastic is the best, and according to the National Cancer Institute, prophylactic mastectomy is an overly aggressive treatment for women with LCIS and no other risk factors.
Now the women most likely to be grappling with the issue of having prophylactic bilateral mastectomy are those who have been diagnosed with a gene that causes susceptibility to breast cancer. Some are taking the initiative in deciding to have this surgery — and in many cases, they are ignoring the recommendation of their doctors.
And why shouldn’t they, you might ask. They are told their risk for getting breast cancer can be as high as 85%, and they are living with the uncertainty that breast cancer could strike at any time. Many have watched mothers or sisters struggle through surgery, radiation, and chemotherapy. They understandably want no part of that.
But there are reasons they should not rush into having this surgery.
Of course, a bilateral mastectomy may be the wisest choice for some women who have the gene, but it is too drastic a step for many others.
The American Institute for Cancer Research (AICR) is a great resource for healthy recipes that follow guidelines they’ve developed for reducing cancer risk. They offer several recipes for nutritious Thanksgiving dishes in addition to the following one for pumpkin pie. Their web site has helpful information about reducing cancer risk and recurrence through lifestyle.
All women are at risk for breast cancer — and most of us think our risk is higher than it actually is.
The commonly cited statistic – that women have a 1 in 8 lifetime risk of breast cancer – is a bit misleading because 1 in 8 women in the United States do not actually get breast cancer. The 1 in 8 number is an estimate of lifetime risk. A woman with average risk has a 1 in 8 chance of getting breast cancer sometime during her life if she lives to be 90. Some women are less likely to get breast cancer, and some have a greater risk. Some will not live to be 90.
A more meaningful way to look at risk is the chance of getting breast cancer during each decade of life. A woman in her twenties has a 1 in 1,837 (0.05%) risk of getting breast cancer, and her risk increases as she ages to a maximum in her seventies of 1 in 26 (3.88%). If you add up the percentages for each decade, you get 13% lifetime risk (1 in 8). During no ten-year period during her lifetime, though, does a woman face a risk of getting breast cancer as high as 1 in 8.
Of course, some women are at greater risk of developing breast cancer. And they, too, overestimate their risk for getting this disease.
Women with a faulty breast cancer gene are said to have “up to” an 85% lifetime risk of getting breast cancer, but according to the National Cancer Institute, the risk ranges from 36% to 87%. As with women who have an average risk, their chance of getting breast cancer increases as they age. (The exception to this is women with close relatives who got breast cancer when they were young.)
Others with a higher than average risk for breast cancer are women diagnosed with precancerous conditions like lobular carcinoma in situ or atypical hyperplasia. Women who have had breast cancer or ductal carcinoma in situ, a noninvasive cancer, are also at increased risk.
It should be noted that many women who are high risk will never get breast cancer. No one knows why they don’t or why some women get breast cancer even though they have no risk factors. The interplay of genetic make-up, age, reproductive history, environmental exposures, and lifestyle determines whether or not we develop breast cancer.
But those of us who are high risk can’t help feeling we’re destined to get breast cancer. Some choose overly aggressive treatment because they can’t live with the possibility that they might get this disease. They get bilateral mastectomies, reducing their risk by 90%. In some cases, this surgery is more drastic treatment than is necessary, and it does not guarantee they will never get breast cancer.
Women do it to ease their fears. Being high risk for breast cancer is more frightening than it should be because of misperceptions about the level of risk for the average woman.
