At 30 years old, Jenna was seven months pregnant when she started having heavy rectal bleeding and cramps. After her son was born, she was diagnosed stage four metastatic colon cancer.

Colon cancer, or colorectal cancer, is caused by abnormal cell growth in the large intestine. “Over a million people are living with colorectal cancer,” says Dr. Freda Lewis-Hall, Senior Medical Advisor for Pfizer. “It’s the third most common cancer in the United States in both men and women,” she says, noting that more than 50,000 people died from the disease in 2019.

She also shares that “the screening guidelines for colorectal cancer have changed, and the American Cancer Society now recommends starting regular colorectal cancer screenings at age 45 instead of 50 for people at average risk. This is because of the rising incidence of colorectal cancer in younger people, like Jenna.”
