Chris Guerette remembers what it felt like when she was diagnosed with breast cancer in August of 2009.

“It was a horrible thing,” she said. “It was devastating to have to tell my kids.”

These days, however, Guerette is proud to say that she’s a breast cancer survivor. Within a few weeks of her initial diagnosis, she had a mastectomy. The procedure successfully removed the cancer, meaning she didn’t have to undergo chemotherapy or radiation treatments.

“I got the best possible outcome — I’ve been granted a lifetime with my family,” she said. “And now I want to ensure that other people can spend their lifetimes with their families.”

Guerette, who works as a secretary at Searsport District High School and Searsport District Middle School, was particularly motivated to help others after she got a phone call from her sister earlier this year. Guerette said her sister had asked her what she was doing in July, and when Guerette said she didn’t yet know, her sister invited her to take part in the Susan G. Komen 3-Day for the Cure — a 60-mile walk that takes place over the course of three days.

“She wanted to do this walk with me,” said Guerette. “She said, ‘Let’s do it.'”

There are a number of 3-Day events around the country, and Guerette and her sister will be taking part in the one in Boston, which will take place July 23-25.

Participants in the walk must raise a minimum of $2,300, a number Guerette said she hopes to “blow out of the water.” She said she was halfway toward that goal already, and had some fundraising efforts planned to help raise the rest of the money.

The first of these is a perennial plant sale, which will take place Thursday, April 29, from noon to 4 p.m. at the school, which is located at 27 Mortland Road in Searsport. Guerette, who confessed to not being much of a green thumb herself, said the sale is the brainchild of SDHS English teacher Kathleen Jenkins.

“She had been thinning out her perennials and said, ‘Hey, let’s do this,'” said Guerette of Jenkins.

In addition to Jenkins, other staff members, parents, students and community members have been donating plants out of their own gardens for the sale. Those who aren’t interested in buying plants would like to help Guerette can simply donate money, she said. Checks can be made out to “The Komen 3-Day,” and can be dropped off at the school when it is open.

Guerette’s son Mike, a senior at SDHS, fellow seniors Rachael Mills and Megan Higgins and junior Lucy Knox have been working on getting the word out about the sale, designing fliers and posters.

Another option to help Guerette meet her fundraising goal is to order a bracelet from SDHS teacher Dawn Staples-Knox to honor someone who has battled breast cancer. Guerette said she would wear the bracelets while she was walking, and said she hoped to have a funny-looking tan on her arms from wearing so many of them.

Guerette said she was looking forward to taking part in the 3-Day event and meeting others who had been affected by breast cancer. In her own family, some people have died from the disease, while others, like her, are breast cancer survivors. She said there were also several teachers at the school who had had breast cancer, and said she thought practically everyone had either had a family member, or had known someone in the community who had had breast cancer.

“I don’t think there’s anyone who hasn’t been affected in some way,” she said.

All of the money raised as part of the 3-Day events, Guerette said, goes to organizations working to fight breast cancer and eventually find a cure. Some money goes toward paying for mammograms for low-income women, for example, while other money funds research.
