Does long-term use of antiperspirants lead to breast cancer?

I am a heavy user of antiperspirants, and I came across an article titled "The Cause of Toxin Accumulation Leading to Malignant Tumors is...
Antiperspirants." The content states that women who use antiperspirants immediately after shaving are at a higher risk of developing breast cancer because the tiny cuts on the skin allow the chemicals in the antiperspirants to enter the armpit directly.
This concerns me greatly.
Is this true?

Ms.
Chen: The mechanism of antiperspirants is to temporarily block the sweat gland openings using aluminum salts.
There are no reports in the medical literature linking them to any form of cancer, so please do not easily believe such rumors; otherwise, it would be difficult to sell any cosmetics.
The main argument of this article is that blocking sweat leads to the accumulation of toxins that should have been expelled through perspiration, potentially causing cancer.
This theory is akin to saying that constipation allows toxins in the stool to continuously affect the intestinal wall, leading to colorectal cancer.
While it is an interesting notion, scientific research has not confirmed it, and it should be regarded as a hypothesis.
If I were to say that when we are feeling down, we should vent our frustrations to expel the "toxins" from our brains to prevent brain tumors, what would you think? Sincerely, Fan Sheng.

The concern regarding the use of antiperspirants and their potential link to breast cancer has been a topic of debate and research for many years. However, current scientific evidence does not support the claim that long-term use of antiperspirants increases the risk of breast cancer.

Antiperspirants work by blocking sweat glands to reduce perspiration. The active ingredients in most antiperspirants are aluminum-based compounds, which temporarily block the sweat ducts. Some studies have suggested that these aluminum compounds could be absorbed through the skin and mimic estrogen, a hormone that can promote the growth of breast cancer cells. However, the majority of research has not found a definitive link between aluminum exposure from antiperspirants and breast cancer.

A comprehensive review of the literature published in 2014 by the National Cancer Institute concluded that there is no conclusive evidence to support the idea that antiperspirants or deodorants cause breast cancer. The American Cancer Society also states that there is no scientific evidence linking the use of antiperspirants to breast cancer.
Regarding the specific concern about applying antiperspirants after shaving, it is true that shaving can cause small nicks and cuts in the skin, which might allow for greater absorption of substances applied afterward. However, the amount of aluminum absorbed through the skin from antiperspirants is considered minimal and not enough to pose a significant health risk.
Moreover, the skin acts as a barrier, and while some chemicals can penetrate it, the body has mechanisms to detoxify and eliminate substances that may enter through the skin. The idea that toxins accumulate in the body to form malignant tumors is an oversimplification of cancer development, which is influenced by a complex interplay of genetic, environmental, and lifestyle factors.

It is also important to note that breast cancer risk factors include age, family history, genetic mutations (such as BRCA1 and BRCA2), hormonal factors, and lifestyle choices such as diet, exercise, and alcohol consumption. While concerns about personal care products are valid, focusing on established risk factors and maintaining a healthy lifestyle is more beneficial for reducing breast cancer risk.

If you are still concerned about the use of antiperspirants, you might consider switching to natural deodorants that do not contain aluminum or other synthetic chemicals. These products are available in many stores and can provide a sense of comfort without the worry of potential risks associated with traditional antiperspirants.

In conclusion, based on current scientific evidence, there is no need to be overly concerned about the use of antiperspirants and their connection to breast cancer. If you have a family history of breast cancer or other risk factors, it is advisable to discuss your concerns with a healthcare professional who can provide personalized guidance and recommendations. Regular breast self-exams and routine screenings, such as mammograms, are essential for early detection and prevention of breast cancer.
