Testing a Low-Methionine Diet for People With Solid Tumors

This is an early-stage pilot study looking at whether a methionine-reduced diet might help people with solid tumors (cancers that form in organs or tissues like the lungs, skin, bones, or brain). Methionine is a natural building block found in foods like meat, eggs, and dairy. Researchers want to see if eating less of it might benefit people who are already receiving their standard cancer treatment. About 25 people will participate in this study.

Some research suggests that certain types of cancer cells may depend on methionine to survive and grow, so reducing dietary methionine might be a way to support standard cancer treatment. This study will help researchers understand whether this dietary approach is practical and safe for cancer patients.
