Most breast cancers are found in women who are 50 years old or older. Some women will get breast cancer even without any other risk factors that they know of.
About 80% of women diagnosed with breast cancer each year are ages 45 or older, and about 43% are ages 65 or above. Consider this: In women ages 40 to 50, there is a one in 69 risk of developing breast cancer. From ages 50 to 60, that risk increases to one in 43. In the 60 to 70 age group, the risk is one in 29.
Approximately 75% of new cases of breast cancer develop in women over the age of 50. The average age of the first diagnosis of breast cancer in women is 60. Approximately 5-10% of breast cancers are due to a strong family history or genetic mutation, such as BRCA1 or BRCA2.
Age-specific incidence rates rise steadily from age 25-29, more steeply from age 35-39 in females and from age 60-64 in males. The highest rates are in in the 90+ age group for females and the 85 to 89 age group for males. Incidence rates are significantly higher in females than males in most age groups.
Breast cancer symptoms at stage 1 may include: Nipple discharge. Dimpling of the skin. Swelling or redness of the breast.
The main factors that influence your risk include being a woman and getting older. Most breast cancers are found in women who are 50 years old or older. Some women will get breast cancer even without any other risk factors that they know of.
You can have breast cancer without knowing it for several years, depending on how quickly it starts, grows, and spreads. Annually, almost 288,000 new breast cancer cases are diagnosed in the United States. More than half of these cancers are found before they spread beyond the breast.
This estimate means that, if the current incidence rate stays the same, a woman born today has about a 1 in 8 chance of being diagnosed with breast cancer at some time during her life. On the other hand, the chance that she will never have breast cancer is 87.1%, or about 7 in 8.
Many people with localized or regional breast cancer survive for 20 years or longer after receiving a diagnosis and treatment. It is rare for someone with distant breast cancer to live for 20 years. However, scientists are continuing to improve treatments for distant breast cancer.
Breast cancer in women
Rates of breast cancer are low in women under 40. About 4% of women diagnosed with breast cancer in the U.S. are younger than 40 [6]. Rates begin to increase after age 40 and are highest in women over age 70 (see Figure 2.1 below).
Median survival time of the 250 patients followed to death was 2.7 years. Actuarial 5- and 10-year survival rates for these patients with untreated breast cancer was 18.4% and 3.6%, respectively. For the amalgamated 1,022 patients, median survival time was 2.3 years.
According to a 2022 article, risk factors for breast cancer worldwide include: experiencing menopause at a later age. undergoing hormone replacement therapy. using hormonal contraception containing estrogen long term.
Potential reasons behind this statistic include larger left breast size, more frequent self-screening of left breast, and right-side breastfeeding preferences.
Lump, thickening or dimpling of the skin of the breast. Warmth or tenderness of the breast. Lymph node swelling under the arm. Flattening of the nipple or discharge from the nipple.
Can you have stage 4 breast cancer with no symptoms? Yes – it is possible to have advanced breast cancer and not experience symptoms. However, you can also experience a number of different symptoms that vary greatly depending on the part(s) of the body affected and may develop over time.
Survival for breast cancer is generally good, particularly if you are diagnosed early. This is probably because of screening, early diagnosis and improved treatment. Survival depends on many different factors.
There are many cancer myths, including stress, that haven't been proven to cause cancer. However, there are proven causes of cancer, and things you can do to reduce your risk.
But getting cancer at a young age is rare. 1 in 2 people will get cancer in their lifetime - one of the main reasons for this being that people are living longer.
Alcohol consumption is one of the major modifiable risk factors for the disease, causing 7 of every 100 new breast cancer cases in the Region. During Breast Cancer Awareness Month, WHO encourages everyone to understand that the risk of breast cancer can be significantly reduced by simply reducing alcohol consumption.
Signs that breast cancer may have spread to the brain
Feeling sick (nausea) and being sick (vomiting) especially when waking in the morning. Weakness or feeling numb down one side of the body. Dizziness, unsteadiness or loss of balance and co-ordination.
Chemotherapy. Chemotherapy is not usually offered for stage 1 breast tumours. It may be offered after surgery (called adjuvant therapy) for these tumours if there is a high risk that the cancer will come back (recur).
