What About Breast Cancer In Men
The stages of breast cancer relate to how much the cancer has grown and how far its spread. Generally, the earlier breast cancer is diagnosed and treated, the higher the chances for long-term survival.
|Stage 0||This is a precancerous stage with no invasive cancer cells.|
|Stage 1||The tumor is small and localized to the breast. There may be a small amount of cancer in nearby lymph nodes.|
|Stage 2||The tumor is still localized to the breast but is larger and may have spread to several nearby lymph nodes.|
|Stage 3||This stage includes cancers that have spread to the skin, chest wall, or multiple lymph nodes in or near the breast.|
|Stage 4||This is metastatic breast cancer, meaning its spread to one or more distant parts of the body, most commonly to the bones, lungs, or liver.|
The stages of breast cancer are based on the following factors:
- whether the lymph nodes contain cancer cells
- whether the cancer has metastasized, meaning its spread to other, more distant parts of the body
Since 2018, the following factors have also been used to determine breast cancer stage:
- whether the cancer cells have hormone receptors and need estrogen or progesterone to grow
- whether the cancer cells have the HER2 protein that helps them grow
- tumor grade, meaning how aggressive the cells look under the microscope

What Is Breast Cancer
Breast cancer is an uncontrolled growth of breast cells. To better understand breast cancer, it helps to understand how any cancer can develop.
Cancer occurs as a result of mutations, or abnormal changes, in the genes responsible for regulating the growth of cells and keeping them healthy. The genes are in each cells nucleus, which acts as the control room of each cell. Normally, the cells in our bodies replace themselves through an orderly process of cell growth: healthy new cells take over as old ones die out. But over time, mutations can turn on certain genes and turn off others in a cell. That changed cell gains the ability to keep dividing without control or order, producing more cells just like it and forming a tumor.
A tumor can be benign or malignant . Benign tumors are not considered cancerous: their cells are close to normal in appearance, they grow slowly, and they do not invade nearby tissues or spread to other parts of the body. Malignant tumors are cancerous. Left unchecked, malignant cells eventually can spread beyond the original tumor to other parts of the body.
Over time, cancer cells can invade nearby healthy breast tissue and make their way into the underarm lymph nodes, small organs that filter out foreign substances in the body. If cancer cells get into the lymph nodes, they then have a pathway into other parts of the body. The breast cancers stage refers to how far the cancer cells have spread beyond the original tumor .

Breast Cancer Statistics In Canada
Each year, the Canadian Cancer Society releases predictive cancer statistics. Just last month, their 2019 report was released. This report highlights most cancers in Canada, including updated estimates of incidence, survival, and mortality.
We encourage you to read the entire publication for yourself. But, in the meantime, heres a quick run-through of their most recent findings as relates to breast cancer in Canada in 2019.
BREAST CANCER IS THE MOST COMMONLY DIAGNOSED CANCER IN CANADIAN WOMEN.
This fact still rings true in 2019. According to the Canadian Cancer Societys 2019 predictive stats, 1 in 8 females is expected to be diagnosed with breast cancer in her lifetime. On top of that, breast cancer is still expected to make up more new cases of cancer in Canadian women in 2019 than other cancers. Heres a snapshot:
THE AGE-STANDARDIZED INCIDENCE RATE HAS NOT CHANGED IN THE PAST 5 YEARS.
In the 1990s, the breast cancer incident rate rose. However, this was largely due to advancements in mammography screening and provincial screening programs that helped diagnose more breast cancers. However, today, there has been virtually no change in the projected age-standardized incidence rate over the past 5 years, moving from 126.1 cases per 100,000 women in 2015 to 128 cases per 100,000 women in 2019.
THE RATES OF BREAST CANCER IN YOUNG WOMEN ARE LOW.
CANADAS BREAST CANCER MORTALITY RATE IS STILL THE LOWEST IT HAS BEEN SINCE 1950.

How Common Is Breast Cancer
Breast cancer is the most common cancer in women in the United States, except for skin cancers. It is about 30% of all new female cancers each year.
The American Cancer Society’s estimates for breast cancer in the United States for 2022 are:
- About 287,850 new cases of invasive breast cancer will be diagnosed in women.
- About 51,400 new cases of ductal carcinoma in situ will be diagnosed.
- About 43,250 women will die from breast cancer.
Breast cancer mainly occurs in middle-aged and older women. The median age at the time of breast cancer diagnosis is 62. This means half of the women who developed breast cancer are 62 years of age or younger when they are diagnosed. A very small number of women diagnosed with breast cancer are younger than 45.

Breast Cancer Survival Rates By Stage And Age
The relative 5-year survival rate for breast cancer is 92%. This means that those who have breast cancer are, on average, 92% 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 92%, the survival rate 10 years after diagnosis of breast cancer is 86%.
Prognosis By Cancer Type
DCIS is divided into comedo and noncomedo subtypes, a division that provides additional prognostic information on the likelihood of progression or local recurrence. Generally, the prognosis is worse for comedo DCIS than for noncomedo DCIS .
Approximately 10-20% of women with LCIS develop invasive breast cancer within 15 years after their LCIS diagnosis. Thus, LCIS is considered a biomarker of increased breast cancer risk.
Infiltrating ductal carcinoma is the most commonly diagnosed breast tumor and has a tendency to metastasize via lymphatic vessels. Like ductal carcinoma, infiltrating lobular carcinoma typically metastasizes to axillary lymph nodes first. However, it also has a tendency to be more multifocal. Nevertheless, its prognosis is comparable to that of ductal carcinoma.
Typical or classic medullary carcinomas are often associated with a good prognosis despite the unfavorable prognostic features associated with this type of breast cancer, including ER negativity, high tumor grade, and high proliferative rates. However, an analysis of 609 medullary breast cancer specimens from various stage I and II National Surgical Adjuvant Breast and Bowel Project protocols indicates that overall survival and prognosis are not as good as previously reported. Atypical medullary carcinomas also carry a poorer prognosis.
Additionally, lymph node metastasis is frequently seen in this subtype , and the number of lymph nodes involved appears to correlate with survival.

Health Disparities In Young African Americans
In addition to these unique issues, research has shown that young African American women face even greater challenges.
- African American women under age 35 have rates of breast cancer two times higher than caucasian women under age 35.14
- African Americans under age 35 die from breast cancer three times as often as caucasian women of the same age.14
- Researchers believe that access to healthcare and the quality of healthcare available may explain these disparities. But scientists continue to investigate.
- Research also shows that young African Americans are more likely to get aggressive forms of breast cancer than anyone else.14

When Should You Get Your First Mammogram
The American College of Obstetricians and Gynecologists recommends women of average risk get their first mammogram at age 40, and the ACOG and the American College of Radiology both recommend that all women be evaluated for their breast cancer risk by age 30.
Many medical societies, including the American Cancer Society, encourage women to have their risk of breast cancer assessed by their OB-GYN, says Katerina Dodelzon, MD, associate professor of radiology At Weill Cornell Medicine. The assessment consists of a lengthy questionnaire that takes into account multiple family factors. If that number is higher than 20 percent the average woman is about 12 percent potentially earlier screening or screening with additional modality like a breast MRI would be considered, Dr. Dodelzon explains.
Breast Cancer Stats In Australia
Breast cancer is the second most commonly diagnosed cancer in Australia. Approximately 57 Australians are diagnosed each and every day. That equates to over 20,000 Australians diagnosed with breast cancer each year.
1 in 7 women are diagnosed with breast cancer in their lifetime.
About 1 in 600 men are diagnosed in their lifetime.
Around 1000 young women are diagnosed with breast cancer each year, equivalent to about 3 young women each day.
In 2022, over 3,200 Australian will pass away from breast cancer . Approximately one woman under the age of 40 is expected to die each week from breast cancer.
Thats 9 Australians a day dying from the disease.
In the last 10 years, breast cancer diagnosis have increased by 33%.
Since the National Breast Cancer Foundation started funding in 1994, the five-year survival rates have improved from 76% to 92%.
Weve come a long way. But theres still progress to be made.
Thats why were committed to funding a broad spectrum of research to help understand risk factors, develop new ways to detect and treat breast cancer, improve quality of life for breast cancer patients, improve treatment outcomes and ultimately save lives.

Physical Activity And Weight
Regular physical activity at all ages reduces the risk of breast cancer. Being physically active for more than 30 minutes a day could reduce breast cancer risk by 20%.
Not being active enough may increase the risk of breast cancer. This risk increases with increased sedentary time, particularly with watching television.
Maintaining a healthy weight throughout life could reduce the risk of postmenopausal breast cancer by 50%. Postmenopausal women who are overweight or obese and achieve a healthy weight may decrease their risk of breast cancer by 50%.
Do Doctors Call With Negative Biopsy Results
If a normal or negative test result comes back, the physician can telephone the patient with the good news, and patients have the option of canceling the follow-up appointment. Although it is preferable to give bad news face-to-face, there may be times when giving bad news over the phone is unavoidable.

Management Of Breast Cancer
Surgery and radiation therapy, along with adjuvant hormone or chemotherapy when indicated, are considered primary treatment. Surgical therapy may consist of lumpectomy or total mastectomy. Radiation therapy may follow surgery in an effort to eradicate residual disease while reducing recurrence rates. There are 2 general approaches for delivering radiation therapy:
- External-beam radiotherapy
Surgical resection with or without radiation is the standard treatment for ductal carcinoma in situ.
Pharmacologic treatment for metastatic breast cancer is typically selected according to the molecular characteristics of the tumor. Agents used include the following :
- Hormone therapy
- HER2-targeted therapy
- CDK4/6 inhibitors
- mTOR inhibitors
- PIK3CA inhibitors
In patients receiving adjuvant aromatase inhibitor therapy for breast cancer who are at high risk for fracture, the monoclonal antibody denosumab or either of the bisphosphonates zoledronic acid and pamidronate may be added to the treatment regimen to increase bone mass. These agents are given along with calcium and vitamin D supplementation.
Two selective estrogen receptor modulators , tamoxifen and raloxifene, are approved for reduction of breast cancer risk in high-risk women. Prophylactic mastectomy is an option for women found to be at extremely elevated risk.
Risk Of Breast Cancer Across Different Ages
The risk of a woman being diagnosed with breast cancer in her lifetime is 1 in 7. The majority of breast cancer cases, about 80%, occur in women over the age of 50.
But breast cancer still occurs in young women, with close to 1000 women under the age of 40 projected to be diagnosed with the disease in 2022.

How Survival Rate Is Estimated
Survival rates for all cancers are estimated by looking at data on large numbers of people who have a certain type of cancer. Researchers gather information about the people over periods of time, such as 5 years, 20 years, or longer.
Living Beyond Breast Cancer, like the American Cancer Society, uses U.S. survival rates based on data from the Surveillance, Epidemiology, and End Results Program, known as SEER, of the National Cancer Institute . The NCI works with the North American Association of Central Cancer Registries to gather this information from every state in the U.S. on an ongoing basis.
For breast cancer, the SEER database uses 5-year relative survival rates. A relative survival rate in breast cancer means that women who have the same stage and type of breast cancer are compared to women in the overall population who do not have cancer. For example, if women who have a certain stage and type of breast cancer are found to be about 90 percent as likely as women who dont have that cancer to live at least 5 years after being diagnosed, then the 5-year relative survival rate for the diagnosed women is 90 percent.
Reducing Your Risks Of Breast Cancer
It may be your mother, your sister, a coworker or a close friend unfortunately, many of us know someone who has been diagnosed with breast cancer. As women age, its increasingly important to manage their risks of breast cancer. Here are some tips to help you take control of your health through lifestyle adjustments and preventive scans.

Family History Of Breast Cancer
A positive family history of breast cancer is the most widely recognized risk factor for breast cancer. The lifetime risk is up to 4 times higher if a mother and sister are affected, and it is about 5 times greater in women who have two or more first-degree relatives with breast cancer. The risk is also greater among women with breast cancer in a single first-degree relative, particularly if the relative was diagnosed at an early age .
Despite a history indicating increased risk, many of these families have normal results on genetic testing. However, identification of additional genetic variants associated with increased risk may prove valuable. Michailidou et al conducted a controlled genome-wide association study of breast cancer that included 122,977 cases of European ancestry and 14,068 cases of East Asian ancestry, and identified 65 new loci associated with overall breast cancer risk. A GWAS by Milne et al identified 10 variants at 9 new loci that are associated with risk of estrogen receptornegative breast cancer.
A family history of ovarian cancer in a first-degree relative, especially if the disease occurred at an early age , has been associated with a doubling of breast cancer risk. This often reflects inheritance of a pathogenic mutation in the BRCA1 or BRCA2 gene.
The family history characteristics that suggest increased risk of cancer are summarized as follows:
