Incidence And Lifetime Risk Of Breast Cancer By Molecular Subtype And Age
Molecular profiling has resulted in breast cancer being divided into four main subtypes, defined by differing expression levels of the Estrogen receptor , Progesterone receptor and growth factor receptor HER2. The subtypes are: Luminal A , Luminal B , HER2 over-expressing and basal . Luminal cancers are most common breast cancer seen followed by HER2 over-expressing and approximately 10% are basal cancers . Currently, the incidence of each molecular subtype has been demonstrated to vary by age group . Recently, molecular testing of breast cancer has further confirmed these trends .
Ovarian Cancer Is Usually Diagnosed In Post
The risk of developing ovarian cancer increases with age, according to the American Cancer Society. Ovarian canceris rare in people under 40 and it usually develops after the onset of menopause. Half of all people with ovarian cancer are diagnosed after the age of 63.
Some of therisk factors for ovarian cancer include using fertility treatments, being overweight, smoking, and having had breast cancer.
Breast Cancer And Teenage Girls
If youre a teenage girl, you might be worried about your risk of getting breast cancer.
Developing breast cancer when youre a teenager is extremely rare. Its also uncommon in women in their 20s and 30s. The vast majority of breast cancers are diagnosed in women over the age of 50.
There can be a lot of unreliable information and scare stories on the internet, so its important to use reputable websites or talk to your GP if youre worried about any changes to your breasts. You can also call our Helpline free on 0808 800 6000 to speak with one of our experts.

Family History Of Breast Cancer
Having a family history of breast cancer increases a persons risk of developing the condition themselves.
A females risk if they have two first degree relatives who have had it. First degree relatives are parents, siblings, and children and can include males.
The recommend genetic testing for females with a family history of breast, ovarian, fallopian tube, or peritoneal cancer.
Can I Live 30 Years After Breast Cancer
Most breast cancer cases are highly treatable, especially when a doctor diagnoses them at an early stage. Many people survive for years or even decades after getting a breast cancer diagnosis and receiving treatment. Typically, the earlier a doctor diagnoses and treats the condition, the better a persons outlook.
If Breast Cancer Has Spread To My Lymph Nodes Do They All Have To Be Removed
Not always, says Tran. We are performing fewer axillary lymph node removal surgeries now. Just a few years ago, if you came to me with breast cancer that had spread to the lymph nodes, those nodes would all have to come out, which raises the risk of lymphedema.
Recent studies have found that for some patients with cancer in their lymph nodes, radiation to the remaining lymph nodes may control local cancer as well as axillary lymph node dissection removing all of your lymph nodes.
Another way to avoid axillary dissection is to shrink the cancer with a course of chemotherapy first. If there is a good response, we can remove fewer lymph nodes.
Detecting Breast Cancer In Younger Women
While theres no way to predict who will get breast cancer, some factors put women at higher risk at a younger age. Breast cancer risk is higher in women with a family history of breast or ovarian cancers at a young age or who have an Ashkenazi Jewish heritage. Having had radiation therapy in the chest is another important risk to know about.
There are some steps you can take, including discussing your family cancer history with your doctor and taking advantage of genetic testing for BRCA and other genetic mutations, if offered, based on your health and family history.
Through research, we are learning more about cancer, genetics, and risk factors, says Dr. Andrejeva-Wright. Young women should be aware of their family history and keep their doctors updated over time as it changes.
Also, while guidelines no longer call for monthly at-home breast exams, Dr. Andrejeva-Wright urges women of all ages to be breast aware. She advises women to do a breast self-exam at least quarterly and to learn all they can about their risk factors.
Breast awareness entails knowing your family history of breast and other cancers, says Dr. Andrejeva-Wright, It also means knowing any behavioral factors that may increase your risk of developing breast cancer, such as weight gain and alcohol consumption , and doing something about it.

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.
Menstrual And Reproductive History
Starting menstrual periods at a younger age or going through menopause at a later age raises the bodys exposure to these hormones, which can increase a persons risk of breast cancer.

Risk Of Breast Cancer By Age
A womans risk of developing breast cancer based on her age is as follows:
- 30 years old: 0.49% or 1 in 204
- 40 years old: 1.55% or 1 in 65
- 50 years old: 2.4% or 1 in 42
- 60 years old: 3.54% or 1 in 28
- 70 years old: 4.09% or 1 in 24
About 5% of breast cancer cases occur in women under 40 years old. It may be more difficult to diagnose breast cancer in young women because their breast tissue is denser than that of older women. Young women and their doctors may also be more likely to ignore a breast lump because of their low risk.
Breast cancer that occurs in young women tends to be more aggressive and less likely to respond to treatment. Women who are diagnosed with breast cancer before age 40 are more likely to have a genetic mutation that puts them at higher risk. Screening for the BRCA gene mutation may begin at age 25.
Other signs for young women to be aware of include:
- A lump in the breast
- Nipple discharge
- Focal pain
- Skin changes on the breast
Mammogram screening is recommended to begin between ages 40 and 50 based on your individual risk factors.
What You Need To Know

Soft Tissue And Bone Cancers
Sarcomas are cancers that start in connective tissues such as muscles, bones, or fat cells. There are 2 main types of sarcoma:
- Soft tissue sarcomas
- Bone sarcomas
Sarcomas can develop at any age, but some types occur most often in older teens and young adults.
Soft tissue sarcomas: These cancers can start in any part of the body, but they often develop in the arms or legs. Rhabdomyosarcoma, a cancer that starts in cells that normally develop into skeletal muscles, is most common in children younger than 10, but it can also develop in teens and young adults. Most other types of soft tissue sarcomas become more common as people age. Symptoms depend on where the sarcoma starts, and can include lumps , swelling, or bowel problems.
Bone sarcomas: The 2 most common types of bone cancer,osteosarcoma and Ewing sarcoma, are most common in teens, but they can also develop in young adults. They often cause bone pain that gets worse at night or with activity. They can also cause swelling in the area around the bone.
Osteosarcoma usually starts near the ends of the leg or arm bones. The most common places for Ewing sarcoma to start are the pelvic bones, the bones of the chest wall , or in the middle of the leg bones.

The Malm Breast Cancer Database
The study cohort consists of all cases of invasive female breast cancer in Malmö, Sweden, diagnosed between 1 January 1961 and 31 December 1991. They were all treated at the same institution, Malmö University Hospital, and no referrals were made to or from the hospital for patients with breast cancer. All residents in Sweden are registered by a unique 10-digit ID number. Breast cancer patients were identified by review of clinical notes and record-linkage with the Swedish Cancer Registry, forming the basis of the Malmö Breast Cancer Database. This was all completed by one surgeon, who also validated all breast cancer diagnoses by reviewing histological material, X-ray examinations, and medical records . The present study was approved by the regional ethical committee in Lund, Sweden .

This risk varies with age and is highest in people who were in their teens when they had radiation treatment. According to the
A number of lifestyle factors can increase someones risk of breast cancer. Being aware of these factors can help them reduce their breast cancer risk.
These lifestyle factors include:
- Being inactive: Physical inactivity increases a persons risk of breast cancer. Getting regular exercise may help reduce this risk.
- Taking hormones: Some types of hormone replacement therapy and hormonal birth control may increase the risk of breast cancer. Finding nonhormonal alternatives may reduce a persons chance of developing breast cancer.
- Being overweight after menopause: After menopause, people who are overweight are more likely to develop breast cancer. Maintaining a healthy weight may help reduce breast cancer risk.
- Drinking alcohol: According to the
Are Women Under 40 At Risk For Breast Cancer
Younger women generally do not consider themselves to be at risk for breast cancer. However, breast cancer can strike at any age: 5% of breast cancer cases occur in women under 40 years of age. All women should be aware of their personal risk factors for breast cancer.
There are several factors that put a woman at higher risk for developing breast cancer, including:
- A personal history of breast cancer or a high risk lesion found by biopsy
- A family history of breast cancer, particularly at an early age
- A family history that is concerning for a genetic syndrome that may put them at a higher risk for breast cancer
- History of radiation therapy to the chest
- A known genetic mutation conferring a high risk for the development of breast cancer
- Ashkenazi Jewish ancestry
Latest Breast Cancer Data
Breast cancer is the most commonly occurring cancer in women and the most common cancer overall. There were more than 2.26 million new cases of breast cancer in women in 2020.
The 10 countries with the highest rates of breast cancer in women and the highest number of deaths from breast cancer in women in 2020 are shown in the tables below.
ASR = age-standardised rates. These are a summary measure of the rate of disease that a population would have if it had a standard age structure. Standardisation is necessary when comparing populations that differ with respect to age because age has a powerful influence on the risk of dying from cancer.

The Social Dimension Of Age
Causal paradigms for cancer typically categorize age along with gender, race, and ethnicity as individual characteristics that are not amenable to intervention. Just as research has shown a lack of precision in various racial and ethnic categories, a great deal of heterogeneity can exist within any age category. In addition, the experience of age is subject to social and cultural influences. Although the challenges of examining differences by race and ethnicity without contributing to societal racism has been noted previously,,, the influence of stereotypes and prejudice based on age has received far less attention.,
Guidelines For Elective Surgical Options
Women with BRCA1 or BRCA2 mutations face a significant risk of breast and ovarian cancer. Prophylactic removal of the fallopian tubes and ovaries is recommended by about age 40. Many women with BRCA1 or BRCA2 mutations will also elect to have their breasts removed. Nipple-sparing mastectomy is an effective option for these women.
Making the decision to have an elective preventive double mastectomy and removal of the ovaries is personal and should be based on many life factors. You must balance where you are in your childbearing years, what your future choices may be, and whether you would prefer to follow a rigorous screening schedule instead of making such a life-altering choice.
Whatever your decision, we encourage you to make an informed choice. If you do elect to have a preventive double mastectomy, our breast specialists will guide you in the appropriate breast surgery reconstruction to help restore your body image after treatment.
If you are interested in discussing ovary removal surgery , we will refer you to one of our gynecological oncologists.

Individualized Breast Cancer Treatment For Older Adults
Tran says her groups approach to dealing with breast cancer in patients of any age is highly individualized. We recommend both the treatments and the order in which the patient will receive them, which is very important. For instance, radiation is not common before surgery, since it makes wound healing more difficult.
She notes that most cancers are found early, and generally surgery is the first step in treatment. But for cancers that are more advanced when they are diagnosed, starting out with chemotherapy can offer some advantages.
In cases where the cancer is advanced, chemotherapy is often done first to shrink the tumor. Another benefit of doing chemotherapy first is the tumors response to the chemotherapy gives us information on your prognosis, and surgery afterward can confirm those findings.
