Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The implementation of SMS in population-based cancer screening programs will improve participation, especially in colorectal cancer screening, will allow a better resource management and reduce costs in both programs.
Specific Hypothesis:
Sending the reminder SMS will have an impact on participation greater than that obtained with the standard reminder (letter) in the colorectal cancer screening program.
The effect of the colorectal cancer screening reminder SMS will be greater among the individuals who have been invited for the first time and not previous participants.
Participation after receiving the invitation by SMS in breast cancer screening will be equal to or better than the letter invitation.
The alternative that includes sending SMS will be cost-effective in relation to the current alternative that you use postal shipping.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention 1: SMS reminders in colorectal cancer screening
SMS reminders will be sent to individuals who received an invitation letter from Colorectal Cancer Screening Program and haven't participated within 6 weeks.
SMS reminders to enhance colorectal cancer screening
Individual randomization will be used. Individuals assigned to the experimental arm with a wrong phone number will get a reminder letter (protocol analysis).
Usual Care 1: Reminder letter in colorectal cancer screening
Reminder letters will be sent to individuals who received an invitation letter from the Colorectal Cancer Screening Program and haven't participated within 6 weeks.
SMS reminders to enhance colorectal cancer screening
Individual randomization will be used. Individuals assigned to the experimental arm with a wrong phone number will get a reminder letter (protocol analysis).
Intervention 2: SMS reminders to return the screening test
SMS reminders will be sent to individuals who picked the fecal immunochemical test at the pharmacy and haven't returned it within 14 days.
SMS reminders to return the fecal immunochemical test at the pharmacy in CRC screening:
Individual randomization will be used. Individuals with a wrong phone number assigned to the experimental arm will not get any reminder (protocol analysis).
Usual Care 2: No intervention
No reminders will be sent.
SMS reminders to return the fecal immunochemical test at the pharmacy in CRC screening:
Individual randomization will be used. Individuals with a wrong phone number assigned to the experimental arm will not get any reminder (protocol analysis).
Intervention 3: SMS invitation among prior participants
Invitation by SMS will be sent to women who previously participated in the Breast Cancer Screening Program.
Invitation by SMS to previous participants in breast cancer screening:
Individual randomization. Women assigned to the experimental arm and with a wrong phone number will get an invitation letter (protocol analysis).
Usual Care 3: Invitation letter
Letter invitations will be sent.
Invitation by SMS to previous participants in breast cancer screening:
Individual randomization. Women assigned to the experimental arm and with a wrong phone number will get an invitation letter (protocol analysis).
