A three-year battle with stage four colon cancer never dampened the spirts of Petaluma resident Lucas Brooks, who throughout his struggle remained positive, humorous and more concerned about others than himself.

A 2001 graduate of Casa Grande High School, Mr. Brooks died on July 22, 2013 at the age of 31.

Mr. Brooks grew up in Petaluma with his parents, Victor and Debbie Brooks, and three siblings. They all graduated from Casa Grande High School, and all worked as newspaper carriers for the Petaluma Argus-Courier.

"I delivered the route in my neighborhood for almost eight years," said Brooks in a March interview with the Argus-Courier. He began delivering papers when he was just 7.

After high school, he went into plumbing and was working with the United Association Local 38 in San Francisco.

In 2009, pain in his lower abdomen prompted him to seek medical attention, but it wasn't until July 2010 that his doctor diagnosed him with colon cancer. After several rounds of chemotherapy, Mr. Brooks decided to look for alternative cancer treatments and traveled to the Klinik Marinus Am Stein in Brannenburg, Germany in February.

"As soon as he got sick, his plan was he would fight it as long as he could," said his sister, Jamaica Ross. "But if it meant he had to go, then that's what was meant to be. His attitude is what took him through the ups and downs."

Ross described her brother as a very positive person who always had a smile on his face and loved being silly.

"He was a goofball who made people laugh all the time," said Ross. "Even during the last three days of his life he was making us all laugh. That's just what Lucas did. He wanted to comfort people. He was more concerned about others than himself."

A spaghetti feed fundraiser was held last week and raised about $6,000 to help with Mr. Brooks' medical expenses.

"A lot of people wrote letters to him at the spaghetti feed," said Ross. "One young lady wrote how Lucas always smiled at people even if he didn't know them. She said that he taught her about being a good person and how you can change lives with a smile."

He is survived by his children, Liam and Camille Brooks; parents, Victor and Debbie Brooks; and siblings Jamaica Ross, Justin Ross and Jared Brooks.

A memorial service is planned in August. Details about the memorial will be announced at a later date.
