Unique Challenges For Young Adults

Breast cancer in young adults is just different. We are at a different phase of our lives and encounter unique challenges compared to older persons. These challenges may significantly impact our quality and length of life. Some of the unique challenges and issues young adults face:

  • The possibility of early menopause and sexual dysfunction brought on by breast cancer treatment
  • Fertility issues, because breast cancer treatment can affect a womanâs ability and plans to have children
  • Many young women are raising small children while enduring treatment and subsequent side effects
  • Young breast cancer survivors have a higher prevalence of psychosocial issues such as anxiety and depression13
  • Questions about pregnancy after diagnosis
  • Heightened concerns about body image, especially after breast cancer-related surgery and treatment
  • Whether married or single, intimacy issues may arise for women diagnosed with breast cancer
  • Challenges to financial stability due to workplace issues, lack of sufficient health insurance and the cost of cancer care

What Is The Average American Womans Risk Of Being Diagnosed With Breast Cancer At Different Ages

Many women are more interested in the risk of being diagnosed with breast cancer at specific ages or over specific time periods than in the risk of being diagnosed at some point during their lifetime. Estimates by decade of life are also less affected by changes in incidence and mortality rates than longer-term estimates. The SEER report estimates the risk of developing breast cancer in 10-year age intervals . According to the current report, the risk that a woman will be diagnosed with breast cancer during the next 10 years, starting at the following ages, is as follows:

  • Age 30 . . . . . . 0.49%
  • Age 40 . . . . . . 1.55%
  • Age 50 . . . . . . 2.40%
  • Age 60 . . . . . . 3.54%
  • Age 70 . . . . . . 4.09%

These risks are averages for the whole population. An individual womans breast cancer risk may be higher or lower depending on known factors, as well as on factors that are not yet fully understood. To calculate an individual womans estimated breast cancer risk, health professionals can use the Breast Cancer Risk Assessment Tool, which takes into account several known breast cancer risk factors.

Who Does Breast Cancer Affect

The age range distribution of breast cancer patients ...

Breast cancer mainly affects older women.

Most breast cancers occur in women over the age of 50. And the older you are, the higher your risk.

Men can also get breast cancer, but this is rare. Most men who get breast cancer are over 60.

Breast cancer is caused by a combination of our genes, environment and lifestyles. Find out more about breast cancer causes.

Benefits Of Mammographic Screening

The ACS systematic review also examined the effect of screening mammography on life expectancy. Although the review concluded that there was high-quality evidence that mammographic screening increases life expectancy by decreasing breast cancer mortality, the authors were not able to estimate the size of the increase 23.

Breast Cancer Incidence By Age

Breast cancer incidence is strongly related to age, with the highest incidence rates being in older people. In the UK in 2016-2018, on average each year around a quarter of new cases were in people aged 75 and over.

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. The gap is widest at age 30 to 34, when the age-specific incidence rate is 2066 times higher in females than males.

Breast cancer , Average Number of New Cases per Year and Age-Specific Incidence Rates per 100,000 Females, 2016-2018

For female breast cancer, like most cancer types, incidence increases with age. There is a brief plateau shortly after age 50 when routine screening starts, reflecting the diagnosis of prevalent cases at first-time screening. The brief drop in incidence shortly after age 70 when routine screening ends may be a compensatory drop as screening has brought forward diagnoses in women in this age group incidence subsequently returns to the rates expected.

Genetics And Breast Cancer Risk

Currently the major genes known to influence breast cancer risk is BRCA1 and BRCA2 . These genes are tumour suppressor genes responsible for DNA damage repair and mutations in these genes result in a significantly increased risk of breast cancer. It is estimated that up 16% of all familial breast cancers are due to mutations in these genes and up to 5% of all breast cancer cases . BRCA1 and BRCA2 mutation carriers < 70 years old face a 57% and 49% risk of developing breast cancer . Importantly, BRCA mutation carriers frequently tend to develop a more aggressive breast cancer and at a younger age . Screening for BRCA gene mutations in high-risk patients has become a priority and scoring systems such as the Manchester scoring system provides a means to identify which patients need increased surveillance . From scoring systems like this, Genetic testing guidelines have recently been introduced for higher-risk patients .

Family history, breast cancer risk and screening.

Current recommendations for patients with detected BRCA mutations are bilateral mastectomies for carriers , with patients who decline surgery to continue high-risk screening. Additionally, genetic screening for first degree relatives is recommended . The genetic testing of patients can have significant personal ramifications, in addition to the consequences for their families and close relatives. Due to this genetic screening is not routine worldwide, with genetic counseling recommended prior to testing .

Introduction to Early Onset Breast Cancer and Risk Factors

In the later stages of breast cancer, the tumors have spread to other lymph nodes. The underarms are some of the first affected areas. This is because of how close they are to the breasts. You may feel tenderness and swelling under your arms.

Other lymph nodes can become affected because of the lymphatic system. While this system is usually responsible for transmitting healthy lymph throughout the body, it can also spread cancer tumors.

Tumors may spread through the lymphatic system to the lungs and liver. If the lungs are affected, you might experience:

  • chronic cough

Differences By Race And Ethnicity

Some variations in breast cancer can be seen between racial and ethnic groups. For example,

  • The median age of diagnosis is slightly younger for Black women compared to White women 63 years old).
  • Black women have the highest death rate from breast cancer. This is thought to be partially because about 1 in 5 Black women with breast cancer have triple-negative breast cancer – more than any other racial/ethnic group.
  • Black women have a higher chance of developing breast cancer before the age of 40 than White women.
  • At every age, Black women are more likely to die from breast cancer than any other race or ethnic group.
  • White and Asian/Pacific Islander women are more likely to be diagnosed with localized breast cancer than Black, Hispanic, and American Indian/Alaska Native women.
  • Asian/Pacific Islanders have the lowest death rate from breast cancer.
  • American Indian/Alaska Natives have the lowest rates of developing breast cancer.

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

Females who have previously had breast cancer are at risk of developing a second breast cancer, either in the other breast or in a different part of the same breast. This is not the same as the first cancer returning.

Having a personal history of certain noncancerous breast conditions can also increase a persons risk of breast cancer. This can include conditions such as atypical hyperplasia, lobular carcinoma in situ, and ductal carcinoma in situ.

HER2 over-expressing cancers have a higher prevalence in post-menopausal women and initially had poor outcomes, prior to the development of targeted treatments . In patients under 40 years old, HER2 over-expressing breast cancers have been linked to a higher recurrence rate . Treating patients with a monoclonal antibody that targets the Her2 receptor, like trastuzumab, has resulted in improved survival . Furthermore, adding trastuzumab to neo-adjuvant chemotherapy has lead to significant increases in the pathological complete responses observed . Development of newer monoclonal antibody treatments has also shown promise, as pertuzumab combined with trastuzumab in the neo-adjuvant setting significantly improves the pathological complete response rate .

Triple negative cancers occur at a younger age and have poorer outcomes than luminal subtypes . Triple negative cancers have been linked to the BRCA1 gene, with studies finding 20%30% of triple negative patients having either the BRCA1 or BRCA2 gene . It was also found that the prevalence increases with decreasing age . Due to this correlation the national comprehensive cancer network recommends that all women under 60 with triple negative breast cancer be referred for genetic counseling . Currently, bilateral prophylactic mastectomy has been shown to reduce the risk of breast cancer in carriers with BRCA1 and BRCA2 mutations .

What Is The Average American Womans Risk Of Developing Breast Cancer During Her Lifetime

Based on current incidence rates, 12.9% of women born in the United States today will develop breast cancer at some time during their lives . This estimate, from the most recent SEER Cancer Statistics Review , is based on breast cancer statistics for the years 2015 through 2017.

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.

For men born in the United States today, the lifetime risk of breast cancer is 0.13%, based on breast cancer statistics for the years 2015 through 2017. This means that a man born today has about a 1 in 800 chance of being diagnosed with breast cancer at some time during his life.

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.

Should Women Under Age 40 Get Mammograms

In general, regular mammograms are not recommended for women under 40 years old, in part, because breast tissue tends to be more dense in young women, making mammograms less effective as a screening tool. In addition, most experts believe the low risk of developing breast cancer at a young age does not justify the radiation exposure or the cost of mammography. However, screening mammograms may be recommended for younger women with a family history of breast cancer and other risk factors.

The exact cause of breast cancer in men is not known, but there are some things that increase your risk of getting it.

These include:

  • genes and family history inheriting faulty versions of genes called BRCA1 or BRCA2 increases your risk of breast cancer
  • conditions that can increase the level of oestrogen in the body including obesity, Klinefelter syndrome and scarring of the liver
  • previous radiotherapy to the chest area

Its not certain that you can do anything to reduce your risk, but eating a balanced diet, losing weight if youre overweight and not drinking too much alcohol may help.

The number of women under 40 being diagnosed with metastatic breast cancer is increasing.

Metastatic breast cancer means that the cancer has advanced to stage 4 and has moved beyond the breast tissue into other areas of the body, such as the bones or the brain. Survival rates are lower for cancer that has metastasized to other parts of the body.

According to the American Cancer Society , the 5-year survival rate for those with breast cancer that has spread to other parts of the body is 27 percent for women of all ages. However, one found no significant differences in median survival rate between younger and older women with metastatic breast cancer.
