Fact : Oral Contraceptives Are An Established Risk Factor For Breast Cancer
Evidence for an estrogenbreast cancer link was published in a New England Journal of Medicine review, Estrogen Carcinogenesis in Breast Cancer . Estrogen levels are 1050 times higher in breast tissue than in blood, and are higher yet in cancerous tissue than normal tissue. Yager and Davidson stated that, The strongest evidence for the role of estrogen in breast cancer has emerged from the experience with the anti-estrogenic chemotherapy drug, tamoxifen, which has been shown to reduce the risk of cancer by 38 percent in the cancer-free breast .
OCs are known to accelerate cell division in girls and young women who take them before their FFTP. A Mayo Clinic Proceedings meta-analysis by Kahlenborn et al. demonstrated a 52 percent increase in the risk of premenopausal breast cancer among parous women who used OCs four or more years before their FFTP . In an accompanying editorial Cerhan noted, that a higher risk of breast cancer for OC use before first full-term pregnancy was first described more than 25 years ago . In other words, this overview finding by Kahlenborn et al. was not an outlier, but reflected a long-standing, even if seldom discussed, scientific understanding.
What was the media’s response to this study with its troubling finding linking OCs and breast cancer? According to Dennis Byrne of the Chicago Tribune, their main response has been silence .
Male Breast Cancer Statistics
Contrary to popular belief, it is indeed possible for men to get breast cancer.
As such, according to the National Breast Cancer Institute, the risk for US-based men is situated at 1 in 1,000 definitely lower when compared to women of the same age.
National Breast Cancer
Though its rare, 2,620 men will likely be diagnosed in the US this year, whereas 520 will lose their lives because of it.
This male breast cancer statistic helps showcase that male breast cancer should be acknowledged. Regardless if it is rare or not, men all over the world must perform checks from time to time to ensure that they arent affected by the disease. Incidence rates have been fairly stable within the last couple of years, yet it is important to note that from a long-term perspective, the occurrence of breast cancer in men has increased, similarly to women, as reported by CDC breast cancer statistics.
National Breast Cancer
In the UK, the Breast Cancer Now Organization estimates that 350 men are diagnosed on an annual basis. 30 of these diagnoses take place in Scotland.
It is believed that similar occurrence rates are found in most areas of the world.

Lifetime Risk Of Breast Cancer Worldwide
Women who live in developed countries tend to have a higher lifetime risk of breast cancer than women who live in developing countries .
Although we dont know all the reasons for these differences, lifestyle and reproductive factors likely play a large role .
Low screening rates and incomplete reporting can make rates of breast cancer in developing countries look lower than they truly are and may also explain some of these differences.
Incidence And Survival Rates
Breast cancer is the most common cancer in women worldwide, with nearly 1.7 million new cases diagnosed in 2012, representing about 25 per cent of all cancers in women. Incidence rates vary widely across the world, from 27 per 100,000 in Middle Africa and Eastern Asia to 92 per 100,000 in Northern America. It is the fifth most common cause of death from cancer in women, with an estimated 522,000 deaths . It is also the most frequent cause of cancer death in women from regions characterised by lower indices of development and/or income , and the second most frequent from regions characterised by higher indices of development and/or income , after lung cancer.
Breast cancer risk doubles each decade until the menopause, after which the increase slows. However, breast cancer is more common after the menopause. Studies of women who migrate from areas of low risk to areas of high risk show that they assume the rate in the host country within one or two generations. This shows that environmental factors are important in the development of the disease.
The cancer statistics quoted in the Third Expert Report are from the GLOBOCAN 2012 database. The International Agency for Research on Cancer updated these statistics in September 2018, after the publication of the Third Expert Report. Find the latest breast cancer statistics.

When all young adults affected by breast cancer work together, we can raise awareness, improve our representation in research and make each other stronger. We are dedicated to these goals, working to turn our unique challenges into opportunities for shared success. Join the movement! Become an advocate for young women with breast cancer.
Basic Information About Breast Cancer
Cancer is a disease in which cells in the body grow out of control. Except for skin cancer, breast cancer is the most common cancer in women in the United States. Deaths from breast cancer have declined over time, but breast cancer remains the second leading cause of cancer death among women overall and the leading cause of cancer death among Hispanic women.
Each year in the United States, about 255,000 cases of breast cancer are diagnosed in women and about 2,300 in men. About 42,000 women and 500 men in the U.S. die each year from breast cancer. Black women have a higher rate of death from breast cancer than White women.

Fact : There Is A Breast Cancer Susceptibility Window Before The First Full Term Pregnancy
Breast cancer surgeon, Angela Lanfranchi, MD, in collaboration with the Breast Cancer Prevention Institute, has contributed to a much greater understanding of normal breast development, as well as the pathophysiological mechanisms that lead to breast cancer.
A distinctive feature of the female breast is that this organ is not fully developed at birth. There is, of course, breast enlargement in girls at puberty, and this tissue is primarily stromal, or support tissue. However, between puberty and the FFTP, there is a susceptibility windowa time when the breast is most susceptible to forming cancer . This susceptibility occurs because the breast is composed primarily of Type 1 and Type 2 lobules.
Under the microscope, Type 1 and Type 2 lobules appear as twigs of a tree. Type 3 and Type 4 appear more like a cluster of grapes. Type 1 lobules account for 85 percent of all breast cancers, and Type 2 account for 12 percent of these cancers. Type 1 and Type 2 lobules have a higher density of hormone receptors, making them more susceptible to hormone stimulation that can result in cancer mutations.
Breast Cancer Survival Rates By Stage And Age
The relative 5-year survival rate for breast cancer is 91%. This means that those who have breast cancer are, on average, 91% as likely as those who dont have the disease to live for at least 5 years after their diagnosis. The survival rate is an estimate across the population, and an individuals chance of survival is dependent on their specific characteristics and the nature of the tumour, such as the stage of the breast cancer at diagnosis, the age, gender and the subtype of the breast cancer .
The 5-year survival rate for Stage 1 breast cancer is, on average, 100% and Stage 2 is 95%. For locally advanced cancers the survival rate is 81%, while the 5-year survival rate for Stage 4 is significantly lower at 32%.
The 5-year survival rate also differs depending on the age group. For those aged over 85, the 5-year survival rate is 75%, while for those between 40 and 44 years of age it is 93%.
While the 5-year survival rate post-diagnosis is 91%, the survival rate 10 years after diagnosis of breast cancer is 86%.

What Is Breast Screening
Cancer screening involves testing apparently healthy people for signs that could show that a cancer is developing.
Breast screening uses a test called mammography which involves taking x-rays of the breasts. Screening can help to find breast cancers early when they are too small to see or feel. These tiny breast cancers are usually easier to treat than larger ones.
It is important to remember that screening will not prevent you from getting breast cancer but aims to find early breast cancers.
Overall, the breast screening programme finds cancer in around 9 out of every 1,000 women having screening.
Findings On Postmenopausal Breast Cancer
There is strong evidence that:
- being physically active DECREASES the risk of postmenopausal breast cancer
- breastfeeding DECREASES the risk of breast cancer in the mother
- being overweight or obese in young adulthood DECREASES the risk of postmenopausal breast cancer
- being overweight or obese throughout adulthood INCREASES the risk of postmenopausal breast cancer
- greater weight gain in adulthood INCREASES the risk of postmenopausal breast cancer
- being tall INCREASES the risk of postmenopausal breast cancer
- consuming alcoholic drinks INCREASES the risk of postmenopausal breast cancer
There is limited evidence that:
- consuming non-starchy vegetables might decrease the risk of oestrogen-receptor-negative breast cancer
- consuming foods containing carotenoids might decrease the risk of breast cancer
- consuming diets high in calcium might decrease the risk of postmenopausal breast cancer

If You Are Called Back
Around 4 out of 100 women are called back for more tests. If this happens, you might feel very worried. But many of these women wont have cancer.
If you are called back because your mammogram showed an abnormal area, you might have a magnified mammogram. This can show up particular areas of the breasts more clearly. These mammograms show the borders of any lump or thickened area. They can also show up areas of calcium .
You might also have an ultrasound scan of the breast or a test to take a sample of cells from the abnormal area
Breast Cancer Mortality Rates Worldwide
Breast cancer is the leading cause of cancer mortality among women in most countries in the world .
Its estimated more than 680,000 breast cancer deaths occurred worldwide in 2020 .
Rates of breast cancer mortality vary around the world
Breast cancer is the most common cause of cancer mortality among women in developing countries .

Breast Cancer Diagnosis And Survival Rates Over The Last 27 Years
The incidence of breast cancer has risen dramatically over the last 27 years, rising from about 9,827 new cases a year in 1994, to over 20,000 new cases a year in 2021. As a result, 1 in 7 women will now be diagnosed in their lifetime.
From NBCFs inception in 1994, five-year relative survival for breast cancer improved from 76% to 91%. This improvement is a result of research. But despite the improved survival rate, this year around 9 Australians will lose their lives to breast cancer every day. In 2021, there was over 3,000 deaths from breast cancer, including 36 males and 3,102 females.
Unfortunately, despite improved survival rates, the number of deaths from breast cancer each year is still rising. This is being driven by the increase in diagnoses.
Nail Polish Products And Treatments
Acrylic nail treatments are of concern for both those administering and receiving the nail treatment. Women of color make up a large percentage of those who work as nail technicians. Bureau of Labor statistics show that nail workers are 6.1% black or African American, 56.7% Asian, and 7.8% Hispanic or Latina. Occupationally, individuals working in this industry are exposed to carcinogens and endocrine disruptors in nail polishes, primers, and glues such as formaldehyde, dibutyl phthalate, hydroquinone, toluene, and ethyl/methyl methacrylate on a daily basis. Studies routinely show that women working in nail salons report health concerns such as rashes,headaches, dizziness, and breathing difficulties, as well as miscarriages, birth defects and cancers.

How Has The Risk Of Being Diagnosed With Breast Cancer Changed In Recent Years
For a woman born in the 1970s in the United States, the lifetime risk of being diagnosed with breast cancer, based on breast cancer statistics from that time, was just under 10% .
The last five annual SEER Cancer Statistics Review reports show the following estimates of lifetime risk of breast cancer, all very close to a lifetime risk of 1 in 8:
- 12.83%, based on statistics for 2014 through 2016
- 12.44%, based on statistics for 2013 through 2015
- 12.41%, based on statistics for 2012 through 2014
- 12.43%, based on statistics for 2011 through 2013
- 12.32%, based on statistics for 2010 through 2012
SEER statisticians expect some variability from year to year. Slight changes may be explained by a variety of factors, including minor changes in risk factor levels in the population, slight changes in breast cancer screening rates, or just random variability inherent in the data.

+ Breast Cancer Statistics And Facts
For years, cancer has held the second position on the list outlining the worlds leading causes of death. Despite millions of dollars being poured into research, it seems like very few advancements in preventing and treating the disease have been made in the last couple of years.
In this article, we will outline several breast cancer statistics and facts, in order to raise awareness about the disease. As such, some of the main topics that will be covered include but are not limited to the prevalence of breast cancer in women and men, treatment plans, survival rates, number of deaths per year, the demographics of breast cancer, and more.
To kick things off, we will mention several elementary breast cancer facts. For one, it represents a type of cancer that develops in the breast area and is composed of breast tissue. Generally, the main warning signs for breast cancer include lumps in the breast area, changes in the shape of the breasts, fluid originating from the nipple, inverted nipples, and patches of skin with an unnatural texture. The main risk factors that can lead to the appearance of breast cancer are: being female, suffering from obesity, engaging in hormone replacement therapy, old age, ionizing radiation, alcohol consumption, family history, lack of physical exercise, and more.
Breast Cancer Incidence Rates Over Time
In the 1980s and 1990s, the rate of breast cancer incidence rose, largely due to increased mammography screening .
The rate of breast cancer incidence declined between 1999 and 2004 . This decline appears to be related to the drop in the use of menopausal hormone therapy after it was shown to increase the risk of breast cancer .
Mammography screening rates also fell somewhat in the early 2000s. However, studies show the decline in the rate of breast cancer incidence during this time was not likely due to the decline in screening rates .
From 2012-2016, the overall breast cancer incidence rate increased slightly . This may be due, in part, to an increase in body weight and a decline in the number of births among women in the U.S. over time .
Trends in incidence rates may be different among some groups of women.
