Spleen Cancer 2025: Symptoms, Diagnosis, and the Expanding Role of Radiotherapy

 

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 (ultrasound/CT-guided)
  • Labs: CBC, flow cytometry, LDH

Radiotherapy in 2025: From Palliation to Curative Intent

Key indications where RT is making a big difference:

  • Splenic lymphoma (indolent or aggressive)
    → Low-dose RT (4–24 Gy) → >90% response, durable remissions in selected cases

  • Symptomatic splenomegaly
    → Palliative splenic RT (classic 1–2 Gy × 5–10 fx) → rapid pain relief, avoids splenectomy

  • Adjuvant after R-CHOP in localized disease
    → Consolidative RT 24–30 Gy → reduces relapse risk

  • Emerging 2025 techniques
    • Proton therapy → precise splenic irradiation with kidney/liver sparing
    • SBRT for oligometastatic disease involving spleen
    • Re-irradiation with carbon ions (select centers)

Treatment Summary & 5-Year Survival (2025 Data)

  • Localized primary lymphoma → 70–85%
  • Splenic angiosarcoma → ~20% (still poor)
  • Secondary lymphoma (treated) → 60–90%

Breast Cancer:Complete Guide to Prevention, Symptoms, Diagnosis & Treatment Options

What is Breast Cancer? Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. It is the most common cancer among women worldwide, but it can also affect men. The breast consists of glands called lobules that produce milk and thin tubes called ducts that carry milk to the nipple. Cancer typically begins in the cells lining these ducts or lobules. Understanding breast anatomy helps in identifying where breast cancer typically develops. Breast cancer can spread when cancer cells invade nearby healthy tissue or travel through the bloodstream or lymphatic system to other parts of the body in a process called metastasis. Types of Breast Cancer There are several types of breast cancer, categorized by where they begin and whether they have spread: Non-Invasive Breast Cancers Ductal Carcinoma In Situ (DCIS): Cancer cells line the...
