PET Scan in Cancer: When Do We Really Need It?

Image
  Understanding the correct role of PET-CT in oncology to avoid unnecessary tests Positron Emission Tomography–Computed Tomography (PET-CT) has become one of the most valuable imaging tools in cancer care. It helps detect cancer spread, guides treatment, and monitors response. However, many patients today are advised PET scans even when they’re not truly required. Overuse of PET not only increases cost but can also mislead treatment decisions. Let’s clearly understand where PET-CT is essential and where it is NOT needed in oncology. ☑️ When PET-CT is Required in Cancer Care 1. Staging of Certain Cancers Before Treatment PET helps identify cancer spread and decide treatment intensity. It is essential for: Lung cancer Lymphomas (Hodgkin & Non-Hodgkin) Head & neck cancers (except early oral cancers) Esophageal cancer Melanoma Carcinoma of unknown primary (CUP) 2. Detecting Recurrence or Residual Disease After treatment, PET-CT is helpful when: T...

Myelosuppression After Chemotherapy: What Every Cancer Patient Should Know to Stay Safe During Low Blood Counts. Dr M G Giriyappagoudar Radiation Oncologist from Hubballi at HCG NMR Cancer centre, Senior Radiation Oncologist, North Karnataka

  Chemotherapy is one of the most effective treatments for cancer. While it helps destroy cancer cells, it can also affect some normal cells in the body, especially the cells produced in the bone marrow. This temporary effect is called myelosuppression . Understanding myelosuppression and knowing how to protect yourself during this period can significantly reduce the risk of serious infections and complications. What is Myelosuppression? The bone marrow, located inside our bones, produces three important types of blood cells: White Blood Cells (WBCs): Fight infections. Red Blood Cells (RBCs): Carry oxygen throughout the body. Platelets: Help stop bleeding. Chemotherapy targets rapidly dividing cells. Since bone marrow cells divide quickly, chemotherapy may temporarily reduce the production of these blood cells. This reduction in blood cell counts is known as myelosuppression . Why Does It Occur? Chemotherapy cannot always distinguish between cancer cells and healthy fast-growing...

When Surgery Is Accidentally Done in Cervical Cancer — Can Radiation Still Cure the Patient?

Image
  Cervical cancer treatment requires careful planning and staging before surgery or radiation. However, in real-world practice, some women present with severe bleeding per vagina and undergo emergency or unintended surgery before the diagnosis of cervical cancer is confirmed. Such situations can create major challenges in treatment planning. Recently, I managed one such complex and highly rewarding case at Anvita Onco Clinic. A Challenging Beginning A woman presented with heavy bleeding per vagina and underwent surgery elsewhere before the complete diagnosis was established. During surgery, the upper body of the uterus was removed, but the cancerous lesion in the cervix remained inside the pelvis. Later, investigations confirmed that the disease was actually carcinoma cervix. When she came for further treatment, the residual tumor measured nearly 6–7 cm , which is considered a locally advanced cervical cancer. Such cases are technically difficult because normal anatomy is altered a...
