How can women overcome HER2-negative breast cancer?

Question

Hello doctor,

I recently heard that my colleague has been diagnosed with HER2-negative breast cancer. This news has deeply affected me and made me concerned about the women in my life. I am trying to understand more about this specific type of breast cancer.

What are the typical next steps in treating HER2-negative breast cancer?
I am also curious about the risk factors. Does this type of cancer affect all women equally, or are there specific factors that increase the likelihood of developing it?
Should I encourage my wife and sister to get checked?
What kind of screening would be appropriate for them?

I want to ensure their health without causing unnecessary alarm. Any information you can provide about HER2-negative breast cancer would be greatly appreciated.

Kindly help.

Thank you.

Hello

Welcome to icliniq.com.

Thanks for your query.

Regarding HR+ and HER2-negative breast cancers:

Typically, HR+ (hormone receptor-positive) breast cancers are considered less aggressive than HR-negative breast cancers. This is because hormone-positive cancers tend to grow more slowly compared to hormone-negative ones.

HR+ HER2-negative breast cancers are sometimes referred to as luminal A breast cancers. These cancers often require less aggressive treatment, sometimes involving only surgery and hormonal therapy, and generally have a good prognosis in the early stages.

Factors that may increase the risk of breast cancer include:

A family history of breast cancer.
A personal history of breast cancer.
A personal history of breast conditions.
Early onset of menstruation.
Late onset of menopause.
Dense breast tissue.
Alcohol consumption.

Additional risk factors for triple-negative breast cancer (TNBC) include:

Age: Premenopausal women and those under the age of 50 have an increased risk of Triple-negative breast cancer.
BRCA1 gene mutation: Approximately 70 percent of breast cancers diagnosed in women with an inherited BRCA1 mutation are TNBC.
Ethnicity: African American and Hispanic women have a higher rate of triple-negative breast cancer.

I hope that you get your answer.

Please let me know if you want some help.

Thank you.
