Does deodorant cause breast cancer? What the research shows
It is a common worry because underarm products are used close to the breast. The US National Cancer Institute (NCI) says “no scientific evidence links the use of these products to the development of breast cancer.” This page explains where the concern comes from, what research does and does not show, and a practical tip for mammogram day.
Can you wear deodorant to a mammogram?
- No. NCI advises avoiding deodorants, antiperspirants, powders, lotions, creams or perfumes around the breasts or under the arms on the day of your mammogram (NCI).
- In a Nov 5, 2026 explainer for The Week, gynecologist Dr Sakshi Goel says substances including aluminium “may have an effect on the images produced” (The Week).
Short answer
The short answer from NCI
NCI says no scientific evidence links antiperspirant or deodorant use to the development of breast cancer, and that a 2014 review found no clear evidence that aluminum-containing underarm antiperspirants or cosmetics increase breast cancer risk (NCI).
NCI also notes that only a few studies have looked at this, that results have been conflicting, and that more research would be needed to settle whether any relationship exists.
Talk to your doctor
Your real risk factors
The Week explainer lists age, genetics, reproductive and hormonal history, alcohol and other lifestyle factors as playing an important role in breast cancer (The Week).
NCI encourages anyone concerned about breast cancer risk to talk with their doctor, and points to its Cancer Information Service at 1-800-4-CANCER.

Why the aluminum question comes up
Antiperspirants and deodorants do different jobs. NCI explains that aluminum-based compounds are the active ingredient in antiperspirants and form a temporary “plug” within the sweat duct. Deodorants, as The Week explainer describes, control odor by masking it or reducing odor-causing bacteria (NCI; The Week).
Because antiperspirants are applied near the breast and left on the skin, some researchers suggested aluminum might be absorbed and have estrogen-like effects. NCI says no studies to date have confirmed any substantial adverse effects of aluminum that could contribute to increased breast cancer risk.
What the studies actually looked at
NCI summarizes a small set of studies. A 2002 study of 813 women with breast cancer and 793 without found no increase in risk among women who reported using an underarm antiperspirant or deodorant. A 2006 study, with 54 women with breast cancer and 50 without, also found no association.
A 2003 retrospective study of 437 breast cancer survivors reported a younger age at diagnosis among women who used these products frequently or started using them together with shaving at an earlier age. NCI notes that because of the retrospective design, the results are not conclusive.
Parabens and the “trapped toxins” myth
Parabens are preservatives that can mimic estrogen in cells. NCI says they have been reported in breast tumors but there is no evidence they cause breast cancer, and that most US deodorants and antiperspirants do not currently contain them.
The idea that blocking sweat traps toxins is a separate myth. In The Week, Dr Goel writes that the main job of sweat is to regulate body temperature, while the liver and kidneys eliminate toxins (The Week).
If you still want an antiperspirant
If heavy underarm sweat is the problem, an antiperspirant is a common first step. AAD notes that non-prescription antiperspirants are only effective for mild hyperhidrosis and many patients need a prescription antiperspirant (AAD). Follow the label, and stop and see a doctor if irritation persists.
Maxim Ulti-Dri lists 15% aluminum chloride and is a topical antiperspirant for underarm sweating. This page does not make any cancer-related or safety-superiority claim about Maxim or any other product.
Maxim Sensitive
Sensitive formula option if standard strength feels too strong on skin.
Shop Maxim SensitiveMaxim is a topical underarm antiperspirant. The research on this page did not test Maxim, and is not evidence that Maxim prevents, treats or replaces any medical treatment. Follow the label; individual results vary.

Concerned about breast cancer risk?
Talk with your doctor about your own risk factors and screening schedule. On mammogram day, skip underarm products.
