Symptoms of inflammatory breast cancer include swelling (edema) and redness (erythema) that affect a third or more of the breast. The skin of the breast may also appear pink, reddish purple, or bruised. In addition, the skin may have ridges or appear pitted, like the skin of an orange (called peau d'orange). These symptoms are caused by the buildup of fluid (lymph) in the skin of the breast. This fluid buildup occurs because cancer cells have blocked lymph vessels in the skin, preventing the normal flow of lymph through the tissue. Sometimes the breast may contain a solid tumor that can be felt during a physical exam, but more often a tumor cannot be felt.
Proper diagnosis and staging of inflammatory breast cancer helps doctors develop the best treatment plan and estimate the likely outcome of the disease. Patients diagnosed with inflammatory breast cancer may want to consult a doctor who specializes in this disease.

I'm Dr. Judy Boughey, a breast surgeon at Mayo Clinic. In this video, we'll cover the basics of breast cancer. What is it? Who gets it? The symptoms, diagnosis, and treatment. Whether you're looking for answers for yourself or someone you love. We're here to give you the best information available.
Just like any cancer, breast cancer results from DNA mutations that instruct your cells to grow out of control. In this case, it targets cells in the breast tissue, and there's no single thing that causes these DNA mutations. There are a wide set of risk factors. But having more of these risk factors, can increase your chances of developing breast cancer. More than anything, your risk is increased by being female. That doesn't mean men don't get it. Actually, men account for about 1 percent of all cases. Another factor is age. The older you get, the more likely a breast cancer diagnosis becomes. A history of breast cancer increases your risk too, that includes your own personal history if you've had it before and your family history. If breast cancer is common in your family tree, you are likely at increased risk of developing it. Scientists have identified several genes that if inherited, are more likely to cause breast cancer. There are many, but the most common and well studied are, BRCA1 and BRCA2. While they don't make breast cancer a certainty, your chances of developing it, are much higher with these particular mutations. Beyond that, radiation exposure at any point in your life increases your risk of breast cancer. As does having children at what is scientifically considered an older age. Starting menopause at an older age and taking post-menopausal hormones.
Things to keep an eye out for that might be signs, include lumps or thickening in your breast, changes in the size or shape of your breast, changes in your breast skin, or a new inversion of your nipple. Peeling, scaling or flaking of the areola and redness or pitting of the skin of your breast that looks like an orange. Most importantly, because these things may or may not be cancer, be sure to check with your doctor if you notice any of these signs.
This can all feel overwhelming. A breast cancer diagnosis is a complicated and scary topic. Keep your friends and family close. Rely on them for practical and emotional support. Find someone to talk with, maybe a friend, relative, clergy member, or medical social worker. A support group can be really helpful to connect with others who have been down this road before. The outlook on breast cancer has improved immensely. Research and scientific advancement have made this disease a very treatable one. With new and constantly improving therapies and expert care, there is plenty of hope. If you'd like to learn even more about breast cancer, watch our other related videos or visit mayoclinic.org. We wish you well.
Researchers have identified hormonal, lifestyle and environmental factors that may increase your risk of breast cancer. But it's not clear why some people who have no risk factors develop cancer, yet other people with risk factors never do. It's likely that breast cancer is caused by a complex interaction of your genetic makeup and your environment.
A number of inherited mutated genes that can increase the likelihood of breast cancer have been identified. The most well-known are breast cancer gene 1 (BRCA1) and breast cancer gene 2 (BRCA2), both of which significantly increase the risk of both breast and ovarian cancer.
A breast cancer risk factor is anything that makes it more likely you'll get breast cancer. But having one or even several breast cancer risk factors doesn't necessarily mean you'll develop breast cancer. Many women who develop breast cancer have no known risk factors other than simply being women.
To perform a breast self-exam for breast awareness, use a methodical approach that ensures you cover your entire breast. For instance, imagine that your breasts are divided into equal wedges, like pieces of a pie, and sweep your fingers along each piece in toward your nipple.
Breast cancer is not a transmissible or infectious disease. Unlike some cancers that have infection-related causes, such as human papillomavirus (HPV) infection and cervical cancer, there are no known viral or bacterial infections linked to the\r\n development of breast cancer.
Approximately half of breast cancers develop in women who have no identifiable breast cancer risk factor other than gender (female) and age (over 40 years). Certain factors increase the risk of breast cancer including increasing age, obesity, harmful\r\n use of alcohol, family history of breast cancer, history of radiation exposure, reproductive history (such as age that menstrual periods began and age at first pregnancy), tobacco use and postmenopausal hormone therapy.
There are many reasons for lumps to develop in the breast, most of which are not cancer. As many as 90% of breast masses are not cancerous. Non-cancerous breast abnormalities include benign masses like fibroadenomas and cysts as well as infections.
Radiotherapy also plays a very important role in treating breast cancer. With early stage breast cancers, radiation can prevent a woman having to undergo a mastectomy. With later stage cancers, radiotherapy can reduce cancer recurrence risk even when\r\n a mastectomy has been performed. For advanced stage of breast cancer, in some circumstances, radiation therapy may reduce the likelihood of dying of the disease.

The USPSTF found inadequate evidence on the benefits and harms of DBT as a primary screening method for breast cancer. Similarly, the USPSTF found inadequate evidence on the benefits and harms of adjunctive screening for breast cancer using breast ultrasonography, MRI, DBT, or other methods in women identified to have dense breasts on an otherwise negative screening mammogram. In both cases, while there is some information about the accuracy of these methods, there is no information on the effects of their use on health outcomes, such as breast cancer incidence, mortality, or overdiagnosis rates.
The results of the meta-analysis of clinical trials from the systematic evidence review commissioned by the USPSTF are summarized in Table 1. Over a 10-year period, screening 10,000 women aged 60 to 69 years will result in 21 (95% CI, 11 to 32) fewer breast cancer deaths. The benefit is smaller in younger women: screening 10,000 women aged 50 to 59 years will result in 8 (CI, 2 to 17) fewer breast cancer deaths, and screening 10,000 women aged 40 to 49 years will result in 3 (CI, 0 to 9) fewer breast cancer deaths.2, 3 Most of these trials began enrollment more than 30 years ago, and these estimates may not reflect the current likelihood of avoiding a breast cancer death with contemporary screening mammography technology. Mammography imaging has since improved, which may result in more tumors being detected at a curable stage today than at the time of these trials. However, breast cancer treatments have also improved, and as treatment improves, the advantage of earlier detection decreases, so that some of the women who died of breast cancer in the nonscreened groups in these trials would survive today.
The most important harm of screening is the detection and treatment of invasive and noninvasive cancer that would never have been detected, or threaten health, in the absence of screening (overdiagnosis and overtreatment). Existing science does not allow for the ability to determine precisely what proportion of cancer diagnosed by mammography today reflects overdiagnosis, and estimates vary widely depending on the data source and method of calculation used.2, 4 In the United States, the rate of diagnosis of invasive plus noninvasive breast cancer increased by 50% during the era of mammography screening (Figure).5 It is not possible to know with certainty what proportion of that increase is due to overdiagnosis and what proportion reflects other reasons for a rising incidence. If overdiagnosis is the only explanation for the increase, 1 in 3 women diagnosed with breast cancer today is being treated for cancer that would never have been discovered or caused her health problems in the absence of screening. The best estimates from randomized, controlled trials (RCTs) evaluating the effect of mammography screening on breast cancer mortality suggest that 1 in 5 women diagnosed with breast cancer over approximately 10 years will be overdiagnosed.6 Modeling studies conducted in support of this recommendation by the Cancer Intervention and Surveillance Modeling Network (CISNET) provide a range of estimates that reflect different underlying assumptions; the median estimate is that 1 in 8 women diagnosed with breast cancer with biennial screening from ages 50 to 74 years will be overdiagnosed. The rate increases with an earlier start age or with annual mammography.7, 8 Even with the conservative estimate of 1 in 8 breast cancer cases being overdiagnosed, for every woman who avoids a death from breast cancer through screening, 2 to 3 women will be treated unnecessarily. 2b1af7f3a8
