  Spleen Cancer 2025: Symptoms, Diagnosis, and the Growing Role of Radiotherapy Radiation Therapy Insights – December 2025 Primary spleen cancer is extremely rare (<1 case per million), but secondary involvement (lymphoma, metastases) is far more common — and 2025 has brought sharper diagnostics and expanded radiotherapy options that directly improve outcomes. Types of Spleen Cancer in 2025 Primary (very rare) : Splenic angiosarcoma, primary splenic lymphoma Secondary (common) : Non-Hodgkin lymphoma, Hodgkin lymphoma, metastases (melanoma, lung, breast) Red-Flag Symptoms – Never Ignore These Left upper abdominal pain or fullness Early satiety (feeling full after small meals) Unexplained weight loss, fatigue, night sweats Easy bruising or bleeding (thrombocytopenia) Enlarged spleen on exam or imaging Diagnosis – 2025 Gold Standard Imaging : CT/MRI abdomen → PET-CT for staging & lymphoma subtyping Biopsy : Core-needle or FNA (u...

3D Conformal Radiation Therapy (3D-CRT) in External Beam Planning 3D Conformal Radiation Therapy (3D-CRT), also known as 3D conformal radiotherapy, is a standard and widely used technique in external beam radiation therapy (EBRT). It shapes high-dose radiation to precisely match the three-dimensional (3D) contours of a tumor while minimizing exposure to surrounding healthy tissues. This represents a major advancement over older 2D planning methods, which relied on simpler X-ray images and rectangular fields that often irradiated more normal tissue. How 3D External Beam Planning Works The process is highly precise and involves several key steps: 1. Imaging and Simulation      • Patients undergo a CT scan (often combined with MRI or PET-CT) in the exact treatment position.      • Immobilization devices (e.g., custom molds, masks, or cushions) ensure reproducibility.      • These scans create a detailed 3D model of the...
