Remember one word: CAUTION
• Changes in bowel or bladder habits.
• A sore that will not heal.
• Unusual bleeding or discharge
• Thickening or lump in any part of the body.
• Indigestion or difficulty swallowing.
• Obvious change in any wart or mole
• Nagging cough or hoarseness.
Diagnosis of Cancer
• Biopsy- Collection of some cells from the tumor and
looking at them under microscope is the only absolute way to diagnose cancer.
• Endoscopy- a flexible plastic tube with a tiny
camera is inserted into any organ to look for benign or malignant tumor.
• Diagnostic Imaging- x rays
• CT scan- more precise than standard x-ray.
• MRI- uses a powerful magnetic field, very accurate
but expensive.
• Blood Tests- some tumors release substances called
tumor markers which can be found in the blood.
Computed tomography (CT) and magnetic resonance imaging (MRI)
In both CT and MRI, patients lie on a narrow table that slides into a
tunnel where images are taken in two-dimensional slices, which are sometimes
reconstructed into three-dimensional images of the brain or cerebral blood
vessels.
