Last reviewed: October 15, 2026 | Guide type: Evidence-based clinical education | Topic: Lung cancer, precision oncology and emerging metabolic strategies Lung cancer is not one disease. It is a collection of biologically different malignancies whose behavior, treatment response and prognosis depend on histology, stage, molecular alterations, immune biology and the patient's overall health. Modern lung cancer care has advanced considerably through early detection, surgery, radiotherapy, molecular profiling, targeted drugs and immunotherapy. Yet important challenges remain: cancers can become resistant to treatment, some tumors lack actionable molecular targets, access to innovative medicines is uneven, and many patients need better options after their disease progresses. This guide brings together two complementary perspectives: Lung Cancer in the Era of Precision Oncology and Lung Cancer Beyond Precision Oncology: The Five-Axis Metabolic Trap . The first perspe...

Last reviewed: October 15, 2026 | Evidence-based patient guide Prostate cancer is not one disease, and a prostate cancer diagnosis does not automatically mean every patient needs immediate surgery, radiation or hormone therapy. Some localized cancers can be monitored safely for years under a structured active-surveillance program. Others have biological features that make early definitive treatment important. A rising prostate-specific antigen (PSA) after previous treatment presents another distinct problem: determining whether recurrent cancer can still be treated locally, whether observation is reasonable, or whether systemic treatment is needed. This guide brings together two related subjects: when less treatment may be more and how to manage biochemical recurrence of prostate cancer . It examines the evidence, separates established treatment from investigational approaches, and provides practical questions for discussions with a urologist, radiation oncologist or medica...
