Do Antiperspirants Increase Breast Cancer Risk? Debunking the Myths

Does using antiperspirants under the arms increase the risk of breast cancer?

Hello Doctor: Recently, I received a forwarded email online urging everyone not to use antiperspirants, claiming that "sweating" prevents toxins from being eliminated, leading to long-term accumulation and causing breast cancer.
It also noted that this information was cited from the United Daily News, but I am unsure if there is any verified research on this topic or if it is just another unfounded internet rumor.
The content of the article is as follows:───────────────────────This article is taken from the United Daily News.
Not long ago, I attended a "Breast Cancer Prevention Seminar" sponsored by Terry Birk, and during the Q&A session, I asked a question: "Why is the most common area for breast cancer located near the armpits?" At that time, no one could answer my question, but recently I received this letter, and I found that it addressed my question.
Now, please reconsider the daily products you use; is there anything that could be carcinogenic? Because starting today, I want to completely change what I use.
A friend forwarded this letter to me, and I showed it to a friend undergoing chemotherapy.
She mentioned that she had learned about this in a support group she recently attended.
The claim is that "the reason for the accumulation of toxins leading to malignant tumors is—antiperspirants." Most products combine both "antiperspirant/deodorant" functions, so quickly check at home if you have many such items.
Those with "deodorant" functions are fine, but "antiperspirants" are not.
The main reason is that the human body has several primary areas for toxin elimination, including the back of the knees (joints), behind the ears, the groin, and the armpits.
They eliminate toxins through "sweating." Antiperspirants clearly state their purpose is to prevent you from sweating, thus blocking the release of toxins from the armpits.
However, these toxins do not disappear; instead, they accumulate in our armpit lymph nodes due to the inability to sweat.
Almost all breast cancers occur in the upper outer quadrant of the breast, which is precisely where the lymph nodes are located.
The reason men are less likely to develop breast cancer is that these antiperspirants are blocked by their body hair and do not come into direct contact with the skin.
Furthermore, women who apply antiperspirants immediately after shaving increase their risk of breast cancer because the tiny cuts on the skin allow the chemicals in the antiperspirants to enter the armpits directly.
Please forward this message to everyone, as the incidence of breast cancer is alarmingly high, and having this knowledge could potentially save many lives.

Please do not casually spread such information that lacks accurate statistical data and is based solely on personal speculation.
I am currently using antiperspirants without any issues, thank you!

More Info

The question of whether antiperspirants increase the risk of breast cancer has been a topic of debate and concern for many individuals. The claims that antiperspirants can cause breast cancer often stem from misunderstandings about how these products work and the nature of breast cancer itself.
Antiperspirants function by blocking sweat glands to reduce perspiration, primarily through the use of aluminum-based compounds. The theory that these compounds could lead to breast cancer is based on the idea that they may be absorbed through the skin and accumulate in breast tissue, potentially causing hormonal disruptions or other cellular changes that could lead to cancer. However, extensive research has not supported this theory.

Numerous studies have investigated the potential link between antiperspirant use and breast cancer. For instance, a comprehensive review published in 2016 in the journal "Cancer" concluded that there is no credible evidence to suggest that antiperspirants or deodorants increase the risk of breast cancer. The American Cancer Society and the National Cancer Institute have also stated that there is no scientific evidence linking the use of these products to breast cancer.
Moreover, the notion that toxins accumulate in the body due to the use of antiperspirants is largely unfounded. The human body has efficient mechanisms for detoxification, primarily through the liver and kidneys, and sweat is not a primary route for eliminating toxins. The lymphatic system, which includes lymph nodes located in the armpits, plays a role in immune function and fluid balance, but it is not a significant pathway for toxin removal.

The claim that breast cancer is more common in areas close to the armpits is also misleading. Breast cancer can occur in various locations within the breast tissue, and while some tumors may be found near the axillary region, this does not imply a direct causal relationship with antiperspirant use.
It is also important to consider the role of genetics and lifestyle factors in breast cancer risk. Family history, age, hormonal factors, and lifestyle choices such as diet, exercise, and alcohol consumption are significant contributors to breast cancer risk.
In conclusion, the fears surrounding antiperspirants and breast cancer appear to be based on myths rather than scientific evidence. Individuals concerned about breast cancer should focus on known risk factors and engage in regular screenings and discussions with healthcare providers about their personal risk and preventive measures.
If you have further concerns about the use of antiperspirants or breast cancer risk, it is advisable to consult with a healthcare professional who can provide personalized advice based on the latest research and your individual health history.
