This clinical trial studies the effect of four different intervention components "tools" on body weight, nutrition, and physical activity in cancer survivors. Studies indicate that people with a history of cancer whose nutrition and physical activity habits are consistent with the American Cancer Society's Nutrition and Physical Activity Guidelines may have longer disease-free survival. The four different intervention components may help patients with a history of cancer adopt recommended health behaviors after they have completed treatment.

PRIMARY OBJECTIVE:

I. To determine the effect of four candidate intervention components (text messaging, digital health tool kit, health coaching, or support person training), and combinations of the four intervention components, on change cancer survivors' American Cancer Society (ACS) guideline score after 48 weeks of intervention.

SECONDARY OBJECTIVES:

I. To determine the effect of four candidate intervention components (text messaging, digital health tool kit, health coaching, or support person training), and combinations of the four intervention components, on cancer survivors' American Cancer Society (ACS) guideline score after 24 weeks of intervention.

II. To determine the effect of four candidate intervention components, and combinations of the four intervention components, on cancer survivors' intake of fruits and vegetables, whole grains, refined grains, red meat, and processed meats; moderate-to-vigorous physical activity; and body mass index (BMI) after 48 weeks of intervention.

EXPLORATORY OBJECTIVES:

I. To determine the effect of four candidate intervention components (text messaging, digital health tool kit, health coaching, or support person coaching), and combinations of the four intervention components, on cancer survivors' American Cancer Society (ACS) guideline score after 12 weeks of intervention.

II. To describe adherence to each intervention component.

III. To explore the effects of each of the candidate intervention components (text messaging, digital health tool kit, health coaching, support person training) on theoretical constructs (e.g., self-efficacy, outcome expectations, self-monitoring, social support) from 0 to 24 and 48 weeks.

IV. To explore whether sociodemographic (e.g., gender, age, race/ethnicity), clinical (e.g., stage of disease, treatment history, ostomy status, time since diagnosis), and/or psychological/behavioral (e.g., self-efficacy, social support, outcome expectations, depression) factors moderate the intervention components' effects on ACS guideline scores.

VII. To explore change in ACS guideline score in relation to change in fasting insulin, glucose, homeostatic model assessment (HOMA-IR), and inflammatory markers (e.g., Interleukin 6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), Tumor Necrosis Factor alpha (TNF-alpha) for a subset of participants from enrollment to 48 weeks among people with a history of cancer.

VIII. To explore change in ACS guideline score in relation to change in fatigue, depression, and sleep quality from 0 to 24 and 48 weeks among people with a history of cancer.

IX. To explore changes in the ACS guideline score in relation to change in the gut microbiome among a subset of participants with a history of cancer.

X. To describe cancer survivors' 10-year cardiovascular risk using the American Heart Association (AHA) Predicting Risk of cardiovascular disease (CVD) EVENTS (PREVENT) score.

XI. Engage stakeholders to identify opportunities for continued optimization of the intervention and prepare for future implementation.

XII. To explore whether aspects of the social or built environment moderate effects of the intervention components on the ACS guideline score

OUTLINE: All patients receive a personal report comparing their nutrition and physical activity to ACS guidelines and a booklet on nutrition and physical activity for patients with a history of cancer.

Inclusion Criteria:

INCLUSION CRITERIA FOR CANCER SURVIVORS:

1. >= 18 years of age.
2. Diagnosis of bladder, breast, colon, endometrial, kidney (renal cell carcinoma), ovarian, prostate, or rectal cancer.
3. Completed all cytotoxic chemotherapy, immunotherapy, targeted therapies, or radiation (if indicated) prior to enrollment. Hormonal treatments are allowed.
4. Owns a smart phone that has access to the Internet and can receive daily text messages.
5. Able to speak and read English or Spanish
6. Have a support person >= 18 years of age who speaks English or Spanish and is willing to provide informed consent and support the participant throughout the study.
7. >= 4 weeks since a major surgery to start of intervention (removal of port or catheter (cath) is not major surgery; reversal of ostomy is major surgery and will require at least 4 weeks prior to enrollment).
8. Readiness, as determined by the Physical Activity Readiness Questionnaire (PAR-Q). If there are any indications that home-based exercise might be unsafe based on PAR-Q, the patient will not be enrolled until confirmation from the patient's provider is received via email and/or phone that they are safe to exercise. Providers do not need to be contacted if patients answer 'yes' to 'Is your doctor currently prescribing any medication for your blood pressure or for a heart condition?

INCLUSION CRITERIA FOR SUPPORT PERSONS:

1. Identified by a cancer survivor participant who has consented to participate in Tools To Be Fit as their support person.
2. 18 years of age or older.
3. Speaks and reads English or Spanish.
4. Consents to complete two online surveys and four 1-on-1 health coaching calls during the 48 week study.

Exclusion Criteria:

EXCLUSION CRITERIA FOR CANCER SURVIVORS:

1. People with potential contraindications to home-based exercise based on the PAR-Q for whom the investigator is unable to obtain physician clearance.
2. ACS guideline score of > 4 out of 6 at enrollment based on self-reported diet, BMI, and physical activity. Our screening survey will ask participants to report their height and weight; usual intake of foods in the ACS guidelines (e.g., red and processed meat, fruits, vegetables, grains); and the Godin Leisure Time Exercise Survey.
3. Used a physical activity tracker and a diet tracking app for >= 1 week in the past 3 months; these are components of our digital health tool kit.
4. Planned major surgery during the study period (removal of port or cath or dermatological procedures excluded)
5. Scheduled to receive any form of cancer therapy during the study period with the exception of hormonal treatments, which are allowed.
6. History of severe cardiovascular, respiratory or musculoskeletal disease or joint problems that preclude moderate physical activity. Examples include unstable angina, recent myocardial infarction, oxygen-dependent pulmonary disease, and osteoarthritis requiring imminent joint replacement. Moderate arthritis that does not preclude physical activity is not a reason for ineligibility.
7. History of psychiatric disorders that would preclude participation in the study intervention (e.g., untreated major depression or psychosis, substance abuse, severe personality disorder) or prevent the patient from giving informed consent.
8. Participating in another weight loss, physical activity or dietary intervention clinical trial. Co-enrollment in some trials involving pharmacologic therapy is allowed. Participants are also allowed to pursue weight loss and physical activity programs on their own, as long as these programs are not provided as part of a clinical trial.
9. Currently pregnant or trying to become pregnant during the study period.
10. Living outside the United States during screening and/or the 48-week study period.

EXCLUSION CRITERIA FOR SUPPORT PERSONS:

1. None.
