October is a Breast Cancer Awareness Month! It is a worldwide annual campaign, involving thousands of organisations including SCORA CIMSA, to highlight the importance of breast awareness, education, and research.
Why is Breast Cancer Awareness Month important?
Breast cancer awareness is important because there is a need to explain the importance of detecting an abnormalities in your breast as early as possible and increasing the chances of successfully managing and treating the disease. So now let’s talk about breast cancer.
What is Breast Cancer?
Breast cancer is a cancer that forms in the tissues of the breast – usually in the ducts (tubes that carry milk to the nipple) or lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.
How Common is Breast Cancer?
Breast cancer is a leading cause of cancer-related deaths in women, with almost 1.7 million cases diagnosed per year and more than half a million deaths every year (Ferlay et al. 2013). In developed countries, 1 in every 8 women will develop breast cancer in their lifetime.
What Causes Breast Cancer?
The precise cause of breast cancer is unknown, but several risk factors for developing the disease have been identified. It is important to remember that having a risk factor increases the risk of cancer developing but it does not mean that you will definitely get cancer. Likewise, not having a risk factor does not mean that you definitely won’t get cancer. Most important risk factors are :
- Female gender
- Exposure to ionising radiation
- Increasing age
- Having fewer children
- Genetic predisposition (family history or mutations in certain genes)
- History of atypical hyperplasia
- Exposure to estrogens
What is Breast Cancer Screening?
- Mammography is a low-dose x-ray procedure that allows visualization of the internal structure of the breast.
- Magnetic resonance imaging (MRI)
- Breast ultrasound is sometimes used to evaluate abnormal findings from a mammogram or physical exam.
- Clinical breast examination (CBE)
- Breast self-awareness, experts have concluded that self-awareness seems to be at least as effective for detecting breast cancer as structured BSE.
How should I Check My Breast?
There’s no right or wrong way to check your breasts. But it is important to know how your breasts usually look and feel.
- A change in size or shape
- A lump or area that feels thicker than the rest of the breast
- A change in skin texture such as puckering or dimpling (like the skin of an orange (Peau D’Orange))
- Redness or a rash on the skin and/or around the nipple
- Your nipple has become pulled in or looks different, for example a change in its position or shape
- Liquidthat comes from the nipple without squeezing
- Painin your breast or your armpit that’s there all or almost all of the time
- Aswellingin your armpit or around your collarbone
What is the Breast Cancer Survival Rate?
Relative survival rates are an estimate of the percentage of patients who will survive for a given period of time after a cancer diagnosis, accounting for normal life expectancy. Survival among cancer patients is compared to survival among people of the same age and race who have not been diagnosed with cancer. Based on the most recent data, relative survival rates for women diagnosed with breast cancer are:
- 91% at 5 years after diagnosis
- 86% after 10 years
- 80% after 15 years
Relative survival rates should be interpreted with caution. First, they are based on the average experience of all women and do not predict individual prognosis because many patient and tumor characteristics that influence breast cancer survival are not taken into account. Second, long-term survival rates are based on the experience of women diagnosed and treated many years ago and do not reflect the most recent improvements in early detection and treatment.
