Jaclyn Smith discovered a lump during a routine checkup in 2002 and underwent a lumpectomy and radiation therapy the following month.

The 'Charlie's Angels' star's diagnosis came 15 years after fellow 'Angels' star Kate Jackson's initial treatment for breast cancer.

In 1985, Smith launched her own line of clothing for Kmart, which has generated more than $300 million in annual sales. Today, a portion of the sales from Smith's clothing and upholstery line goes to breast cancer research.
