Under Age 30 at Diagnosis

Finding out in your teens or 20s that you have breast cancer may disrupt school, college, early work life or relationships. It can leave you feeling isolated from others your age and wondering if anyone like you is going through the same thing.

As a young adult woman with breast cancer, your challenges and needs are distinct, even from those of “older” young women.

Very Young Women With Breast Cancer

Only about 1 percent of all breast cancers happen in women younger than 30 years old, yet it is the most frequently diagnosed cancer in women of that age group.

Some factors increase breast cancer risk in teen and young adult women.

Family history is a strong influence in young women’s diagnoses. Your risk is greater if you havea mother, father, grandmother, sister, brother, aunt or uncle who was diagnosed with breast cancer. A diagnosisinfo-icon in a first-degree blood relative (parent,siblinginfo-icon, child) increases your risk more than history in other close relatives.

In addition,

  • having a blood relative who was diagnosed before age 30 raises your risk of getting breast cancer while very young
  • you may inherit from either your mother or father a BRCA1 or BRCA2 gene mutation, increasing your risk of breast cancer
  • mutations in BRCA1info-iconBRCA2info-icon or TP53 genes are found in about half of women with a significant family history of breast cancer
    • BRCA1 or BRCA2 mutations are more likely in younger women compared with those diagnosed when older (after menopauseinfo-icon)
    • TP53 mutationinfo-icon (Li-Fraumeni syndrome) is rare but causes breast cancer in very young women
    • you may have a BRCA or TP53 geneticinfo-icon mutation even without a family history of breast cancer

Talk with a genetic counselor to understand the impact of your personal family health history on your risk of getting breast cancer. Find out more in LBBC’s Guide to Understanding Genetics and Family Risk Assessment.

Other risk factors

  • young age and pregnancy
    • 10 to 20 percent of breast cancers under age 30 are diagnosed during pregnancy or in the first year after giving birth
    • multiple births heighten risk by raising hormonal levels for several months after each pregnancy
    • recent use of oralinfo-icon contraceptives (birth control pills)
      • increases exposure to hormones

Disease characteristics that can affect very young women include

Parents, Family and Friends

Some young women say the hardest part of receiving a breast cancer diagnosisinfo-icon is telling their mothers and fathers. They worry about the distressinfo-icon their parents will feel on hearing the news.

Often with good intentions, some parents rush in to take over managing care. Others may be less intrusive, helping at medical appointments or with babysitting, cooking and errands. For very young women living on their own, or independent but living at home, it can be difficult to feel dependent on parents again, even for a short time.

Siblings can be strong supports, but long-standing conflicts may create problems. Extended family members, such as cousins, might provide help with less emotional intensity. Friends or acquaintances sometimes act like extended family, especially for young women who live far from relatives.

Going through diagnosis and the demands and side effects of treatment may strengthen a relationship with a steady or live-in partner, or spouse. The stresses also can cause that relationship to end.

Emotional Pressures

Women who are very young when diagnosed with breast cancer may have added psychosocialinfo-icon concerns, including

  • being single, with no partner or family nearby to help
  • having small children to care for
  • risk of infertility from treatment
    • need to preserve fertilityinfo-icon right away, although not necessarily thinking about having a child yet
    • fertility preservation can be costly
    • adjusting to the possibility of never having children
    • losing or not getting a job due to diagnosisinfo-icon or treatment
    • effects on school progress
    • inadequate or no health insurance or financial instability
    • emotional health
      • worry about dating or maintaining current relationship
      • feeling isolated from friends and peers involved in “normal” age-related social activities and career pursuits
      • anxiety and depression—more long-lasting in women diagnosed before age 30
      • few support groups focus on young women’s issues
