Cancer survival is not influenced by a patient's emotional status

A large-scale study published in CANCER journal found that a patient's emotional state has no direct or indirect effect on cancer survival or disease progression. The research analyzed data from over 1,000 patients with head and neck cancer, concluding that psychological factors are not independently prognostic in cancer management.
