Six years after disbanding, real-life siblings Kevin, Joe and Nick Jonas have officially reunited as the Jonas Brothers. Their song “Sucker” was released today (view the video above). The song’s debut coincides with the start of Colorectal Cancer Awareness Month. The brothers’ dad, Kevin Jonas Sr., is a survivor of colon cancer.

As Cancer Health previously reported, Jonas Sr. was diagnosed with Stage 2 colon cancer in 2017. During his first colonoscopy, doctors discovered a large mass in his colon; it was later surgically removed and determined to be cancer.

In addition to undergoing six weeks of chemotherapy, Jonas Sr. also overcame several complications from surgery. His family remained by his side during the whole ordeal.

Doctors declared Jonas Sr. to be in remission on December 22, 2017. He’s been cancer-free ever since.

In 2018, Jonas became national spokesperson for Fight Colorectal Cancer (Fight CRC), a national advocacy organization that educates people on the importance of early detection through screening.

On February 4, World Cancer Day, Jonas Sr. posted a throwback photograph on Instagram of himself receiving cancer treatment. He captioned it: “Shout out to my fellow cancer survivors! #worldcancerday @fightcrc #cancersucks.”

Following the release of “Sucker,” Nick Jonas posted an Instagram video in which his father could be seen reading comments from fans while listening to the song.

“Dad, you are the best and your love and support over the years mean the world,” wrote Nick in the video’s caption.

Jonas Sr.’s diagnosis has led his sons, including 18-year-old “Bonus Jonas,” Frankie, to be more cognizant of their health and to get screened earlier for colon cancer. (Having a family member diagnosed with colon cancer increases a person’s risk of developing the disease.)

Family members of a survivor should be screened 10 years prior to the survivor’s age at diagnosis, says Fight CRC.

According to the American Cancer Society (ACS), colorectal cancer is the third most common cancer diagnosed in both men and women in the United States. This year, the ACS predicts about 101,420 and 44,180 new cases of colon and rectal cancers, respectively.
