I disagree. Telling to not eat folate will help them.
If it was not true why are they giving you drugs to stop the folate cycle?

Why continue to eat something that has been proven over and over again to drive tumor growth?
It was LITERALLY how they found out that methotrexate worked.
https://cen.acs.org/food/diet-change-course-cancer/100/i33 Indeed, the very first potent cancer drugs were based on the effects of cell metabolism. In the late 1940s, while pediatric pathologist Sidney Farber was treating children with anemia—a condition brought about because they had leukemia —he found that using folate (vitamin B9) could make the leukemia advance surprisingly quickly. That led him to successfully treat their leukemia with methotrexate, a drug that inhibits folate activity. Methotrexate is still widely used against cancer and several other diseases today.

I agree, but that doesn’t really help those who have cancer at the moment.
Some claim a ketogenic diet may help. https://pubmed.ncbi.nlm.nih.gov/31399389/ . "Major conclusions: The ketogenic diet probably creates an unfavorable metabolic environment for cancer cells and thus can be regarded as a promising adjuvant as a patient-specific multifactorial therapy."
