As released by the Canadian Cancer Society Fall 2013
An estimated 23, 800 women will be diagnosed with breast cancer and 5,000 will die of it.
An estimated 200 men will be diagnosed with breast cancer and 60 will die of it.
Ontario has the highest number of new cases this year at 9,300 & Prince Edward Island with 100.
1 in 9 females (11.5%) are expected to develop breast cancer in their lifetime.
Women who are between the ages of 30-39 have a 0.4% change of developing breast cancer. While women aged 40-49 have a 1.3% chance.
The age distribution for 10-year tumour-based prevalence for breast cancer in women aged 20-29 (0.2%). Women aged 30-39, (2%).
18% of breast cancer cases will occur in females under age 50.
There is little variation seen in breast cancer incidence and mortality rates across Canada
Between 2001 and 2007 for males and between 1998 and 2007 for females, overall mortality rates declined significantly. The rates declined, on average, by at least 2% per year for breast cancer.
The data indicate that females are more likely than males to be diagnosed with cancer in the prime of their lives (between the ages of 20 and 59 years), which reflects patterns for specific cancers, such as breast and thyroid.
Cancer incidence rates across the country are decidedly uneven, with higher rates in the east and lower rates in the west.
In 2013, 1,050 women across Canada between the ages of 20-39 will be diagnosed with breast cancer.
On average, mortality rates declined by at least 2% per year for women diagnosed with breast cancer.
Females have a 1 in 29 chance of dying from breast cancer.
After its peak in 1986, the age-standardized mortality rate has fallen 42%, from 32.0 deaths per 100,000 in 1986 to a projected rate of 18.7 deaths per 100,000 in 2013. The downward trend has accelerated to 2.4% per year since 2000, which is likely due to a combination of increased mammography screening and the use of more effective therapies following breast cancer surgery.

FAQs
What is breast cancer?
Breast cancer is a type of cancer where cells in the breast tissue divide and grow in an abnormal and uncontrolled way and cause a tumour to form.

There are millions of cells in your body and each cell contains thousands and thousands of genes. Genes contain information, which control cell behaviour. If the genes in even a single cell malfunction, cancer can occur. Gene malfunction can be caused by exposure to cancer-causing agents in the environment or may be the result of rare errors in the normal mechanisms that replicate and repair cells. It may also be inherited.

How is breast cancer treated?
Breast cancer is not one single disease and cannot be treated as such. It is found in many forms and various stages. Thanks to progress in research in the past decade, we now have the sophistication to tailor treatments. Anyone with breast cancer should consult with a medical oncologist to determine her or his specific treatment needs. The main types of breast cancer treatment include surgery (lumpectomy or mastectomy), radiation, chemotherapy and hormone therapy.

How common is breast cancer? How many women are diagnosed each year?
Breast cancer is the most common cancer among Canadian women. One in nine (11%) Canadian women is expected to develop breast cancer during her lifetime (this means by age 90).

Breast cancer is the most common cancer in women aged 20-59, accounting for 37% of new cancer cases. In Canada, 4,408 women under age 50 are diagnosed with breast cancer each year. About 1,100 are under the age of 40. Though the numbers seem small, younger women with breast cancer have many unique needs and require age-appropriate support.

What unique challenges do younger women with breast cancer face?
Young women with breast cancer experience isolation as well as challenges with dating, sexuality, fertility, child care, finances, employment and more. Treatment and care issues include delays in diagnosis, generally more advanced cancers at diagnosis and higher mortality rates, low participation in clinical trials, lack of age-appropriate care, concerns around social support during cancer treatment, as well as late effects of treatment, second cancers and long-term psychosocial issues for cancer survivors.

How does Rethink define “young” women?
Generally, Rethink focuses on raising awareness, providing education and supporting women with breast cancer in their 20s, 30s and early 40s.

Are there things I can do to reduce my risk of breast cancer?
Though the causes of breast cancer are not known, studies show there are things you can do to try to reduce your risk. Read Rethink’s Tips for reducing your risk and learn about early detection through the T.L.C.: Touch. Look. Check.
