The purpose of this study is to develop a secure method of collecting dietary and nutritional intake information from people with cancer. The researchers will use this information to learn more about how dietary information may relate to cancer diagnosis and response to treatment, and to identify factors that may lead to higher or lower risk of cancer.

Inclusion Criteria:

• Patient is receiving or planning to receive therapy for cancer.
• Patient (or caregiver) has sufficient English proficiency.

Exclusion Criteria:

• None

Several prospective subcohorts of patients will be recruited in a rolling fashion. The first 3 subcohorts will comprise allo-HCT, auto-HCT, and CAR-T recipients.
