The Postal Service will mark Breast Cancer Awareness Month in October by highlighting its semipostal research stamp.
Approximately 12.4 percent of women will be diagnosed with breast cancer at some point in their lifetime, according to the National Cancer Institute.
The Breast Cancer Research stamp is available year-round at Post Offices and usps.com.
More than 1 billion stamps have been sold since its inception in 1998, raising more than $87.8 million for breast cancer research. Sales from the stamp also helped fund a landmark study on early-stage breast cancer.
USPS offers two other semipostal stamps.
In November, USPS will promote its Alzheimer’s semipostal stamp. The stamp, which was issued last year, has raised more than $524,000 to fund Alzheimer’s research.
The Save Vanishing Species semipostal stamp will be promoted in December and has raised more than $5.2 million since its 2011 debut to help protect threatened and vanishing species.
