There is no definitive link between aluminum-containing antiperspirants and cancer. An internet rumor from the late 1990s claimed a possible link between antiperspirants and breast cancer, because of a theoretical idea that toxins from antiperspirants could be absorbed and cause cancerous mutations. This has not been conclusively supported by evidence and is not considered a concern in the medical and scientific community.
