Advanced Breast Cancer Common Myths & Misconceptions
Understanding the facts about advanced and metastatic breast cancer is essential for making informed medical decisions. Below are clarifications for common myths and misconceptions surrounding the disease.
Myth: Having bilateral mastectomies prevents metastatic breast cancer
Fact: While bilateral prophylactic (preventive) mastectomies reduce the risk of developing breast cancer by approximately 90%, surgery cannot remove 100% of breast tissue. Microscopic cells left behind in residual tissue can still develop into cancer.1
Furthermore, if cancer cells have already metastasized to other parts of the body prior to surgery, removing the breasts will not prevent a metastatic recurrence elsewhere. Currently, no single strategy guarantees complete prevention.1
Myth: If breast cancer recurs, it’s proof you didn’t get the right treatment in the first place
Fact: No treatment can guarantee that cancer will never return. Standard treatment plans are evidence-based strategies designed to reduce recurrence risk as much as possible, but microscopic cancer cells can survive initial treatment, remain dormant, and re-emerge years later—even when initial care followed optimal clinical standards.2
Myth: There’s no treatment for metastatic breast cancer
Fact: While metastatic (Stage IV) breast cancer is currently considered treatable rather than curable, many effective therapies exist. Modern treatment options include endocrine (hormone) therapy, targeted therapy, immunotherapy, chemotherapy, radiation, and surgery. Thanks to ongoing treatment advances, many individuals live for years with metastatic breast cancer as a manageable chronic condition.3,4
Myth: If you participate in a clinical trial, you may get only a placebo
Fact: Placebos are rarely used alone in cancer clinical trials when an effective standard treatment exists, as withholding care is unethical. Oncology trials typically compare the current "gold standard" treatment to a new experimental therapy, or combine standard care with either an experimental drug or a placebo. In almost all cases, every participant receives at least the current standard of care. Other trials focus on diagnostic tools, surgical techniques, or quality-of-life interventions rather than medication.3
Myth: Breast cancer is the leading cause of cancer-related deaths in women
Fact: Breast cancer is the most common non-skin cancer diagnosed in women, but lung cancer remains the leading cause of cancer-related mortality among women in the United States, with breast cancer ranking second.4,5
Myth: Only women get breast cancer
Fact: Anyone with breast tissue can develop breast cancer, including men. Male breast cancer accounts for roughly 1% of all breast cancer diagnoses. Men are more likely to be diagnosed at later stages, primarily due to lower awareness of male breast cancer and delays in seeking medical evaluation when symptoms appear.6
Myth: Breast cancer only occurs in older, post-menopausal women
Fact: While breast cancer risk increases with age, it can and does occur in younger women. Approximately 10% to 11% of all invasive breast cancers are diagnosed in women under age 45, and it remains one of the most frequently diagnosed cancers in young adults.4,7
