Diagnosis of Lacrimal Gland Tumor

Executive Summary

Different tests are available to diagnose the development of a lacrimal gland tumor, depending on signs and symptoms, age and health status, types of tumor, and earlier medical tests. Physical examination, imaging tests, and biopsies are the diagnostic approaches for diagnosing head and neck cancer. The most common diagnosis of lacrimal gland tumor includes a physical examination, biopsy, imaging tests (Magnetic resonance imaging (MRI), Computed Tomography (CT scan), bone scan, and Positron Emission Tomography (PET Scan).

Diagnosis of Lacrimal Gland Tumor

Doctors use numerous techniques and tests to diagnose a lacrimal gland tumor. They conduct various tests and scans to look for tumor spread or metastasis signs. Imaging tests can play a vital role in determining whether the cancerous growth has metastasised to other body parts or not. Cancer diagnosis plays an essential role in deciding the best treatment plan for a patient’s tumor condition.

The doctor may conduct a detailed physical examination of the suspected area to diagnose the tumor. But physical examinations may not guarantee accurate results. A biopsy is the most preferred way to detect any form of tumor or cancerous growth. In a biopsy, the doctor or physician will take a tiny tissue sample from the suspected area to be sent to the lab for detailed analysis. A biopsy may not be possible in some circumstances, and in those cases, the doctor or the healthcare team may recommend other diagnostic tests or treatments ​1​.

How a person’s cancer is diagnosed differs from one person to the next. Before deciding on a diagnostic procedure, the doctor may examine the following factors:

  • The tumour type that is suspected.
  • Signs and symptoms associated with the illness.
  • overall health condition and age of the patient
  • Past medical history and tests.

The following are diagnostic procedures used to diagnose lacrimal gland tumors ​2​:

  1. PHYSICAL EXAMINATION: The doctor will conduct a detailed examination of your body to check for unusual growth, lumps or bumps. Physical examinations help your doctor get an initial understanding of your disease condition. The doctor will enquire about the signs and symptoms that you are experiencing. You may also be required to produce your past medical records for reference. The doctor will prescribe more tests and scans to get a precise diagnosis as per the physical examination.
  2. BIOPSY: A biopsy is a procedure in which a tiny piece of tissue is removed and examined closely under a microscope. Other procedures may indicate the presence of cancer, but only a biopsy can provide a definitive diagnosis. A pathologist examines the sample taken during the biopsy. A pathologist is a clinician who specializes in diagnosing disease by interpreting laboratory tests and assessing cells, tissues, and organs. The tumor’s location determines the sort of biopsy required. A surgeon performs an incisional biopsy by cutting into the tumor growth and removing a tissue sample. The surgeon removes the entire tumor with an excisional biopsy, which is typically performed for mixed benign epithelial tumors. A tiny needle biopsy removes a small amount of tissue for inspection under a microscope by putting a needle straight into the tumor to collect cells. It’s debatable if a fine needle biopsy should be used to diagnose a lacrimal gland tumor. For further information, consult your physician.
  1. COMPUTED TOMOGRAPHY (CT or CET) SCAN: A CT scan uses an x-ray machine to generate a three-dimensional image of the body interior. A computer then combines the images into a complete cross-sectional view that reveals abnormalities or malignancies. Before the CT procedure, a specific contrast medium dye is sometimes used to improve image detail. This dye can be delivered to the patient via their veins (intravenously) or in the form of a tablet or pill.
  1. MAGNETIC RESONANCE IMAGING (MRI): in this procedure, Magnetic fields, not x-rays, are used to provide detailed images of the body. The tumor’s size can also be measured using an MRI scan. Before the scan, a specific dye called a contrast medium is usually administered to generate clear pictures. This dye can be administered in a pill or a tablet or injected into the patient’s vein (intravenously).
  1. BONE SCAN: in this scanning procedure, a radioactive tracer is used to view within the bones during a bone scan. The radioactive substance is administered intravenously. A unique camera detects it as it gathers in sections of the bone. The camera shows healthy bone as grey, whereas regions of harm, such as those caused by a tumor appear dark.

POSITRON EMISSION TOMOGRAPHY (PET) SCAN: A PET scan generates images of organs and tissues within the body. The patient is given a tiny amount of radioactive sugar material to inject into their body. The cells that use the most amount of energy absorb this radioactive material. Cancer absorbs more of the radioactive substance since it uses energy actively. The material is then detected by a scanner, which produces images of the inside of the body.
