Paediatric Cancers, Head and Neck Cancers, CNS Tumours, Uro-gynaecological Cancers : These all refer to specific types of cancer affecting different parts of the body. Paediatric cancers target children, head and neck cancers affect the head and neck region, CNS tumours grow in the central nervous system (brain and spinal cord), and uro-gynaecological cancers develop in the urinary system (including kidneys and bladder) and the reproductive organs.

Stereotactic Radiosurgery (SRS) and Functional Radiosurgery : These are highly precise radiation therapies used to treat small tumors or lesions. SRS is typically for cancerous tumors, while functional radiosurgery can target non-cancerous growths to improve function (e.g., tremors in Parkinson's disease).

IMRT, IGRT and VMAT : These are advanced radiation therapy techniques. IMRT (Intensity Modulated Radiotherapy) shapes the radiation beam to conform to the tumor's shape, sparing healthy tissue. IGRT (Image Guided Radiotherapy) uses imaging during treatment to ensure accurate targeting. VMAT (Volumetric Modulated Arc Therapy) delivers radiation with a continuously moving gantry for improved dose distribution.

Proton Beam Therapy : This is a specialized form of radiation therapy that uses protons instead of X-rays. Protons can deliver a more precise dose of radiation, potentially reducing side effects compared to traditional X-ray therapy.

Bile Duct Cancer, Bladder Cancer, Esophageal Cancer : These refer to treatments for cancers of the bile ducts (liver), bladder, and esophagus, respectively. Treatment options depend on the cancer stage and other factors.

Carcinoma of Unknown Primary (CUP) : This refers to cancer that has spread but the origin (primary tumor) is unknown. Treatment focuses on managing the spread and may involve surgery, chemotherapy, or radiation therapy.

Castleman Disease : This is a rare non-cancerous disorder affecting the lymph nodes. Treatment depends on the type and severity and may involve surgery, medications, or chemotherapy.

Cervical Cancer, Endometrial Cancer : These are cancers of the cervix and endometrium (lining of the uterus) in women. Treatment typically involves surgery, radiation therapy, or a combination.
