How can a hormone pill, skin patch, or vaginal insert, ring, or cream raise cancer risk?

"***I only use a hormone skin patch. It just replaces my lost hormones. How can it cause breast cancer?***"

Hormones can be absorbed orally (from the gut mucosa), from skin (patches), and/or from vaginal mucosa (like a vaginal cream, tablet, or suppository).

Once the hormone is absorbed into the bloodstream, it circulates throughout the body via the blood circulation. The breast, ovarian, and uterine tissues are rich in estrogen receptors. The increased hormones can cause cancers in these three tissues.

After menopause, the reproductive activity of a woman stops. As a result, the reproductive hormones are reduced. This occurs naturally and is safe.

However, to boost the reproductive hormones artificially to their original level when you are not reproductively active is unnatural. This is not safe.

With increased hormones, the previously dormant reproductive tissue cells in the breast, ovaries, and uterus become active again. These old cells split to reproduce more young cells.

Some of these old cells may make a mistake during cell splitting because they are "old" cells. This mistake is called a cell mutation. Some mutations may cause cells to become cancerous.

Estrogen promotes old reproductive cells to cause cancer is a well-established fact. It has been documented by tens of thousands of scientific research articles. But drug companies do not want you to know that because if you are aware of that, you would not buy their drugs.

If you are interested in learning more about the risk of estrogen in causing breast cancer, you can go to PubMed:  [https://pubmed.ncbi.nlm.nih.gov/](https://pubmed.ncbi.nlm.nih.gov/)

In the search bar, type "estrogen cancer risk." Press the Return key, and you will see that there are 20,657 related scientific papers. Among them,  15,334 papers are about breast cancer.

The number of scientific papers on estrogen-causing cancers increases daily. Here is a blog article to summarize all the newly published scientific evidence:

The take-home message is that estrogen supplements (including bioidentical hormones) can cause breast, ovarian, and uterine cancers. If you do not wish to get these cancers, you should seek a safer alternative.

Is there a safe and better alternative to estrogen? The answer is "Yes!" NeuEve is safer and better.
