Colon cancer on the rise in young adults.

Nearly 18,000 people under the age of 50 will be diagnosed with colorectal cancer this year in the United States, said Rebecca Siegel, M.P.H., of the American Cancer Society. But the disease is still relatively rare, affecting far less than 1% of younger adults.

Experts don’t know what’s causing the jump in colorectal cancer among young adults. But they do know some factors that raise the risk of colorectal cancer in older adults, including obesity, physical inactivity, and smoking.

Most of the discussions about the possible causes of early-onset disease converged on three interrelated factors: diet, bacteria in the gut, and inflammation.

Human Papilloma Virus Vaccine Information

In this observational study, they used an extension of the age-period-cohort Poisson model to estimate the relative risk of cervical cancer in three vaccinated cohorts compared with earlier cohorts that were not eligible for HPV vaccination. Data from a population-based cancer registry were extracted, and were assessed for diagnoses of cervical cancer and CIN3 in women aged 20–64 years and who were a resident in England. They used three vaccinated cohorts to account for differences in the school year in which the vaccine was offered and its national coverage. Adjustment for confounding was made using information on changes in cervical screening policy and historical events that affected cervical cancer incidence. Results were compared across models with different adjustments for confounders.
