Can Deodorants or Anti-Perspirants Really Cause Breast Cancer?

Mahima Choudhary, Tahira Kashyap, Hina Khan, and Chhavi Mittal are popular celebrities who share more than just their careers in Bollywood and television; they are all breast cancer survivors. According to the World Health Organisation (WHO), breast cancer is the most common cancer among women in 157 out of 185 countries, and India records some of the highest case numbers globally, following only China and the US.

As the causes behind the global rise in breast cancer continue to evolve, a persistent fear remains among women that deodorants or anti-perspirants cause breast cancer. It is a question many women quietly worry about, especially since these products are applied so close to the breast area. The flow of lifestyle and health content on Social media and forwarded messages often amplifies this anxiety.

In a conversation with the editorial team at Onlymyhealth, Dr Vani Parmar, HOD - Breast Oncosurgery & Surgical Oncologist at KIMS Hospitals, Thane, and Dr Niti Raizada, Principal Director – Medical Oncology & Hemato-Oncology, Fortis Hospitals, Bengaluru underlined that this is one of the most common myths she encounters in her clinic. 

Breast Cancer Cases in India

According to the World Cancer Research Fund, breast cancer is the leading cancer among women. In 2022, India recorded the highest number of cases after China and the US. According to a report published by the World Health Organisation on August 14, 2025, breast cancer is a disease in which abnormal breast cells grow out of control and form tumours. If not treated in time, these tumours can spread throughout the body and become fatal.

Further research indicates that female breast cancer is the leading cause of cancer incidence and mortality in India, accounting for 13.5% of new cancer cases and 10% of cancer-related deaths in 2020. These statistics justify the fear among women and the urge to identify possible causes, specifically whether deodorants or anti-perspirants are to blame for the rising numbers.

Where Did This Fear Begin?

Anti-perspirants contain aluminium-based compounds that temporarily reduce sweating. Over time, two major assumptions gained popularity:

First: Aluminium can behave like oestrogen.

Second: Blocking sweat traps toxins inside the body

Dr Parmar gently clarifies, “Sweating is not how our body removes toxins. That job is done by the liver and kidneys. Using an anti-perspirant does not cause harmful substances to build up in the breast.”

Dr Raizada notes," Antiperspirants work by temporarily blocking sweat ducts using aluminium-based compounds, but only very small amounts of aluminium are absorbed through the skin, and this is well below harmful levels in healthy individuals."

What Does Science Actually Say?

As mentioned in American Cancer Society, there are no strong epidemiologic studies that link breast cancer risk and antiperspirant use, and very little scientific evidence to support this claim.

Dr Parmar also notes that years of large-scale research studies have investigated this concern, and the conclusion has remained consistent that there is no proven link between deodorant or anti-perspirant use and breast cancer.

“The amount of aluminium absorbed through healthy skin is negligible,In fact, we consume much higher amounts naturally through food and water without any evidence of an increased cancer risk,” she states.

Dr Raizada also highlights that there is currently no strong scientific evidence to show that deodorants or antiperspirants cause breast cancer. "These products have been studied for many years, and large research reviews have not found a direct link between their regular use and an increased risk of breast cancer," she states.

What About Parabens and Hormones?

Some people worry about parabens, preservatives once used in deodorants that can weakly mimic oestrogen. While traces have been found in breast tissue, Dr Parmar emphasises that this does not mean they cause cancer.

“Finding a substance in the body doesn’t mean it triggered the disease. There is no scientific proof linking parabens in deodorants to breast cancer,” she notes. Furthermore, many modern brands have removed parabens from their formulations altogether.

Lumps Near the Armpit

Dr Parmar highlights another common misconception - the belief that breast cancer appears near the armpit specifically because of deodorant use. In reality, this area simply contains a significant amount of breast tissue (the axillary tail), making lumps more common and easier to detect there.

Dr Raizada also mentions an important point that some people worry that shaving the underarms before applying deodorant allows more chemicals to enter the body. "While shaving can cause minor skin irritation, there is no reliable evidence to suggest that it significantly increases the absorption of ingredients from deodorants or antiperspirants," she adds.

What Really Matters for Breast Health

Dr Parmar encourages women to focus their energy on factors that truly make a difference. Below are a few key contributors to breast health shared by Dr Parmar and Dr Raizada:

• Maintaining a healthy weight
• Staying physically active
• Limiting alcohol and other intoxicant consumption
• Understanding family history
• Timely screening

“Early awareness and regular screening remain far more important than deodorant choices,” Dr Raizada suggests.

Bottomline

Dr Parmar states that there is no scientific evidence proving that deodorants or anti-perspirants cause breast cancer. While you may experience skin irritation or allergies due to certain fragrances, these do not equate to cancer. Choosing a product that suits your skin is perfectly fine, and fear does not need to be part of your daily routine. Staying informed, listening to your body, and seeking medical advice early are the strongest steps toward long-term breast health.
