This was tested in people. That is the most reliable kind of research we share.
This is a report about one patient, not a test of a new treatment.
The short version
One woman said no to standard breast cancer treatment, and seven years later the cancer had spread to her brain.
What was studied. Doctors reported on one patient. She was a 63-year-old woman with HER2-positive breast cancer that had already reached lymph nodes under her arm.
What they found. She turned down all the standard treatments. That included chemotherapy, radiation, hormone therapy, and anti-HER2 drugs. She used only Chinese herbal medicine instead. After seven years of follow-up, doctors found a cancer spot in her cerebellum, a part of the brain. It measured 2.3x2.7 cm. The cancer had also spread to her thyroid, which doctors call an extremely rare place for breast cancer to go. Lab tests on the thyroid lump confirmed it came from her breast cancer.
What this means, and what it doesn't
What it could mean: HER2-positive breast cancer can spread quickly when it is not treated. The standard treatments, including anti-HER2 drugs, are offered because they help. This report also points to the need for drugs that can reach the brain, since the brain is a common place for this cancer to spread.
What it doesn't mean: This is one person's story, not a study. It cannot tell you what will happen to you or to anyone else. It does not prove that herbal medicine caused the cancer to spread. There is no new treatment here, and nothing in this report is a cure or a promise. Talk with your own care team about your own plan.
