Episode number: 

Over 200,000 women are diagnosed with breast cancer every year; 40,000 of them do not survive. In fact, breast cancer is second only to lung cancer as the leading cause of cancer death among women in the United States. 

Breast cancer detection and treatment is not the clear-cut, black-and-white process many of us might expect.  In this episode, our panelists talk about the grey areas that every woman should know about.  They address these questions and more:

  • If I do everything right, can I prevent breast cancer?  
  • If I have a negative mammogram, am I safe?  
  • If I get breast cancer, how can I be sure I'm getting the right treatment?

The risk of getting breast cancer increases dramatically with age.  So, if you or someone you care about is approaching 40, you'll want to watch this episode.

Quick Facts

With the exception of skin cancer, breast cancer is the most common form of cancer affecting women in the United States. More than 212,000 women are diagnosed with breast cancer each year.

Breast cancer risk becomes greater as women age.

Between the ages of:Your risk of developing breast cancer is:
30 to 401 in 250
40 to 501 in 67
50 to 601 in 35
60 to 701 in 28

Your cumulative lifetime risk - your chance of getting breast cancer from age 0 to the day you die - is 1 in 8 (13%)

Mammograms used in combination with clinical breast exams by a physician are the most effective method of detecting breast cancer. Women over the age of 40 should have a yearly mammogram. 

Only 1 or 2 mammograms out of every 1,000 lead to a diagnosis of cancer. Approximately 10% of women will require additional mammograms. Do not be alarmed if this happens to you. Only 8% to 10% of those women will need a biopsy, and 80% of those biopsies will not be cancer. 

When detected early, cure rates for breast cancer are 90% and up.

Breast cancer affects more than 1,450 men in the U.S. each year.  Experts do not recommend routine screening for men.

Key Point 1

Evaluation of a suspicious breast should proceed until both the doctor and the patient are convinced there is a reasonable chance no cancer exists.

Early detection of breast cancer involves a progression of steps.  A combination of breast self-exam, clinical breast exams and mammography is the first line of defense.

Mammography, which shows the internal structure of the breast, can screen for signs of a problem well before anything can be felt or symptoms expressed.  By definition, breast cancers found before they are symptomatic are more likely to be smaller and, in the case of the less aggressive forms, still confined to the breast.

Unfortunately, no technology is perfect and mammograms miss up to 20% of the breast cancers that are present at the time of screening. These false-negatives occur more often in younger women than in older women because the breast tissue of younger women is denser .  Other causes for false-negative results include:

  • A tumor's location (it may be in an area that is not easily imaged);
  • The presence of shadows that can obscure a mass; 
  • The size of the tumor;
  • The tumor's rate of growth;
  • The level of hormones, such as estrogen and progesterone, in a woman's body;
  • The experience and skill of the radiologist.  

On the opposite end of the spectrum is the false positive.  If a woman gets 10 or more mammograms, there's about a 50/50 chance that one of them will result in a false positive.

Bottom line - mammography is not perfect.  But, most doctors feel (and our panel of experts agree) that it is improving, and it does make a difference.  Many mammography providers have started to provide double reads - meaning mammograms are read by two radiologists.  When they do, false negative and false positive rates drop considerably. Finally, while there has been controversy about mammography in the medical community and in the press over the years, the American Cancer Society continues to recommend that women get routine mammograms starting at age 40.

What if you get a clean mammogram but develop a suspicious symptom like a breast lump, skin change or unusual nipple discharge?  In short, don't delay.  Talk to your doctor about further evaluation.  There are a number of other diagnostic procedures that can be done to put your mind at rest or to confirm that you need to begin treatment.  They include:

  • Diagnostic mammography
  • Ultrasonography
  • Breast Magnetic Resonance Imaging (MRI)
  • Ductography
  • Ductal lavage
  • Biopsy

How far do you go?  Our panelist, Gretchen Ahrendt, M.D., puts it this way.  "You should advocate for yourself."  She adds, "Doctors go by the rule of threes.  The physical exam, breast imaging and pathology all have to agree."       

The ultimate answer is a triad:  

  • Try not to be more apprehensive than you need to be.  After all, statistics are on your side, and not all lumps or changes in breast tissue mean you have breast cancer.  
  • Recognize the inherent shortcomings of today's breast cancer detection procedures, and do not be complacent if your mammogram fails to find a problem.  In other words, keep doing your breast self-exams and going to your doctor for a regular clinical breast exam.  If you do find a problem, pursue it until you get a definitive answer, even if it means a biopsy.
  • Support research efforts to develop better tests to detect breast cancer at its earliest stages.

Key Point 2

The powerful prognostic factors that influence the treatment of breast cancer are the size of the tumor, whether it is invasive or not, if it's metastatic at the time of diagnosis, if it's hormonally sensitive and if there is a family history of breast cancer.  Regardless of the treatment options, the patient's choice is ultimately a personal one.

Fact:  Breast cancer should more accurately be called breast cancers.  The disease is not a singular one, but several, and each type is unique.  You can think of them in two main categories - invasive breast cancer and in situ breast cancer .  The invasive cancers can be further broken down into another two categories - those that spread very early in their development and those that spread more slowly as they grow

Fact: Each woman with breast cancer will be diagnosed at a distinct stage of the disease

Fact: Tumor tissue can be estrogen-receptor or progesterone-receptor positive or negative.  A positive result means the cancer uses hormones to stimulate growth and it can be treated by blocking the circulation of that hormone in the body.

Fact: A family history of breast cancer can affect the timing of treatment, treatment response and outcome.  A very high-risk woman may start treatment before cancer shows up with a chemoprevention drug or even with prophylactic (preventive) mastectomy. And, while studies have shown that the combination of lumpectomy and radiation is equivalent to mastectomy for most women, it is uncertain if women with strong family histories are good candidates for this breast-conserving therapy.

Fact: Cancer treatments all have disadvantages as well as advantages

Fact:  Every woman will react to treatment differently, both physically and emotionally

Fact (and theory): In many cases, there is no way to predict with absolute certainty whether a cancer has spread. (In the past, breast cancer was thought to grow in an orderly progression from a tiny tumor in the breast tissue to a larger one, sequentially traveling out to the nearby lymph nodes , then distant ones, and finally to other parts of the body. Now, however, it is thought that cancer cells are capable of traveling from the breast through the blood and lymphatic system very early in the course of the disease.)

There is no one treatment plan that is right for every woman.  It all boils down to probabilities and weighing risks versus benefits.  Breast cancer treatment has to be tailored to each individual woman based on a treatment's probability of success as well as on her preferences.  Each woman will have a unique treatment goal that can vary from treating a cancer as aggressively as possible to choosing not to receive treatment at all.   

Fortunately, new treatment methods and options are continually presenting better odds with fewer side effects.  And, doctors and researchers are developing more tools that can help women with their decision-making process. Until we reach an ideal world, though, be prepared to hear "We don't know ."  Doctors will tell you there are just too many variables so you do the best you can by calculating odds and doing what our panelists recommend -- deciding what degree of uncertainty you can live with and then moving forward. 


Key Point 3

There are risk factors for breast cancer.  The ones you cannot control are getting your period early in life, your age, and a family history of breast cancer.  The risk factors you can control are hormone replacement therapy, not smoking and not using alcohol excessively.

Left out of the statement above is the most obvious of risk factors -- gender.  Men do get breast cancer, but the likelihood of women getting breast cancer compared to men is 100 to 1.  That said, no one knows the exact causes of breast cancer and doctors cannot really explain why one woman gets breast cancer and another does not.  
Risk factors you can't control

Getting your period early in life is one of the big three uncontrollable risk factors and it all boils down to estrogen.  The longer a woman is exposed to estrogen (whether it is made by the body, taken as a drug or delivered by a patch), the more likely she is to develop breast cancer. Women who began menstruation at an early age (before age 12), went through menopause late (after age 55), never had children or who took hormone replacement therapy for an extended period of time are at an increased risk for developing breast cancer.

Age is by far the greatest risk factor. Breast cancer is extremely rare under the age of 30, and is unusual up to 40. The risk of getting breast cancer goes up to about 18% among women in their 40's, while about 77% of women with breast cancer are older than 50 when they are diagnosed. 

A family history of breast cancer is a predictor for about 5% to 10% of breast cancers.  Having one first-degree relative (mother, sister, or daughter) with breast cancer approximately doubles a woman's risk, and having two first-degree relatives increases her risk five-fold. Risk is also higher among women whose close blood relatives have this disease. Blood relatives can be from either the mother's or father's side of the family.   The National Cancer Institute states that risk is higher if the relative(s) developed breast cancer in both breasts, or developed breast cancer before menopause. Also, a family history of ovarian cancer, increases the risk of breast cancer.

Risk factors you can control

 Hormone replacement therapy was once thought to improve a woman's odds of not getting breast cancer.  However, in 1999, a study in The Journal of the American Medical Association (JAMA) linked hormone replacement therapy (HRT) after menopause to increased risk of uncommon forms of breast cancer that have good prognoses. HRT was not associated with the more common types of breast cancer, invasive lobular or ductal breast cancer and ductal carcinoma in situ (DCIS).

There is currently research being done to determine the link between cigarette smoking and breast cancer, and we do know that smoking affects overall health and increases the risk for many other cancers, as well as heart disease.

Use of alcohol is clearly linked to increased risk of developing breast cancer. Women who have 2 to 5 drinks daily, have about 1.5 times the risk of women who drink no alcohol. Alcohol is also known to increase the risk of developing cancers of the mouth, throat, and esophagus.

Remember that all risk factors are based on probabilities, and even someone without any risk factors can still get breast cancer. Proper screening and early detection are the best weapons in reducing the mortality associated with this disease.
