Younger women generally do not consider themselves to be at risk for breast
cancer. Only 5% of all breast cancer cases occur in women under 40 years old.
However, breast cancer can strike at any age, and women of every age should be
aware of their personal risk factors for breast cancer. (A risk factor is a condition
or behavior that puts a person at an increased chance for developing a disease.)
There are several factors that put a woman at high risk for developing breast
cancer, including:
Risk factors include:
* A personal history of breast cancer or some non-cancerous breast diseases.
* A family history of breast cancer, particularly in a mother, daughter or
sister.
* History of radiation therapy Evidence of a specific genetic defect
(BRCA1/BRCA2 mutation). Women who carry defects on either of these genes
are at greater risk for developing breast cancer.
* A Gail Index score of at least 1.7% (The Gail Index uses risk factors such as
age, family history of breast cancer, age of first menstrual period and first
pregnancy, and number of breast biopsies to calculate a woman's risk of
developing breast cancer within the next five years.)
Some studies have suggested that extended use of oral contraceptives (the Pill)
results in a very slight increased risk for developing breast cancer over those who
have never taken them. Women who have stopped using birth control pills for
more than 10 years do not seem to be at any greater risk. Other studies, however,
show no such effect. Researchers continue to study the conflicting results in
these trials to determine if birth control pills play a role in breast cancer.
What Is Different About Breast Cancer In Younger Women?
Diagnosing breast cancer in younger women (under 40 years old) is more
difficult because their breast tissue is generally denser than the breast tissue in
older women. By the time a lump in a younger woman's breast can be felt, the
cancer often is advanced.
In addition, breast cancer in younger women may be aggressive and less likely
to respond to treatment. Women who are diagnosed with breast cancer at a
younger age are more likely to have a mutated (altered) BRCA1 or BRCA2 gene.
Delays in diagnosing breast cancer also are a problem. Many younger women
who have breast cancer ignore the warning signs -- such as a breast lump or
unusual discharge -- because they believe they are too young to get breast cancer.
Many women assume they are too young to get breast cancer and tend to assume
a lump is a harmless cyst or other growth. Some health care providers also
dismiss breast lumps in young women as cysts and adopt a "wait and see"
approach.
Can Breast Cancer In Younger Women Be Prevented?
Although breast cancer may not be prevented, early detection and prompt
treatment can significantly improve a woman's chances of surviving breast
cancer. More than 90% of women whose breast cancer is found in an early stage
will survive.
When women learn at a young age about the risks and benefits of detecting
breast cancer early, they are more likely to follow the recommendations
regarding clinical exams and mammograms. Young women also need to
understand their risk factors and be able to discuss breast health with their
health care providers.
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.
What's the Best Way for Younger Women to Screen for Breast Cancer?
The American Cancer Society (ACS) recommends that all women 20 years of age
or older should perform monthly breast self-examinations. The best time to
perform BSE is the day after your monthly period ends. Becoming familiar with
the look and feel of their breasts offers the best chance for a young woman to
notice any changes.
In addition to monthly BSE, regular clinical breast exams performed at least
every 3 years by your doctor are recommended for all women beginning at age
20. Annual screening mammograms also are recommended at age 40. Women
younger than 40 who have a family history or other risk factors for breast cancer
should discuss their risk and an appropriate screening schedule with their health
care providers.
How Is Breast Cancer Treated In Younger Women?
The course of treatment for breast cancer at any age is based on the extent of the
person's disease (whether or not it has spread beyond the breast), as well as the
woman's general health and personal circumstances.
Treatment options include surgery: either a lumpectomy, which involves
removing the lump and some surrounding tissue, or a mastectomy, which is the
removal of a breast.
Radiation therapy is generally used following a lumpectomy, and chemotherapy
and/or hormone therapy often are recommended after surgery to help destroy any
remaining cancer cells and prevent recurrence.
Breast cancer poses other challenges for younger women, as well, such as
sexuality, fertility and pregnancy after breast cancer treatment.
