Blood Tests<\/b><\/strong><\/li>\n<\/ol>\nBlood tests for cancer<\/b><\/strong>\u00a0can provide information about blood cells, organ function, inflammation, and certain substances associated with particular cancers.<\/p>\nA complete blood count, for example, measures red blood cells, white blood cells, platelets, haemoglobin, and other blood components. It can help doctors identify abnormalities and is particularly useful in evaluating some blood cancers. Blood chemistry tests can also provide information about organs such as the liver and kidneys.<\/p>\n
However, abnormal blood results do not automatically mean that a person has cancer. Similarly, normal blood results cannot always rule out cancer.<\/p>\n
\n- Ultrasound<\/b><\/strong><\/li>\n<\/ol>\n
Ultrasound uses sound waves to create images of internal organs and tissues. It is commonly used to examine areas such as the abdomen, pelvis, thyroid, breast, and other soft tissues.<\/p>\n
Doctors may use ultrasound to investigate an abnormality found during an examination or to help distinguish between fluid-filled and solid areas. It can also be used to guide certain biopsy procedures.<\/p>\n
\n- X-Ray<\/b><\/strong><\/li>\n<\/ol>\n
X-rays use a small amount of radiation to produce images of structures inside the body. A chest X-ray, for example, may help doctors evaluate abnormalities in the lungs or chest.<\/p>\n
Although more advanced imaging techniques are often required for detailed evaluation, X-rays can sometimes provide useful initial information and may lead to further testing.<\/p>\n
\n- CT Scan<\/b><\/strong><\/li>\n<\/ol>\n
A CT scan for cancer<\/b><\/strong>\u00a0uses computer-controlled X-rays to produce detailed cross-sectional images of the body. These images can help doctors identify the location and size of a suspicious mass and assess nearby structures.<\/p>\nA contrast material may sometimes be used to make particular organs, blood vessels, or abnormal areas easier to see.<\/p>\n
CT imaging can also contribute to cancer staging by helping doctors determine whether a cancer may have spread to other parts of the body.<\/p>\n
\n- MRI Scan<\/b><\/strong><\/li>\n<\/ol>\n
An MRI scan for cancer<\/b><\/strong>\u00a0uses a strong magnetic field and radio waves to create detailed images of organs and soft tissues. MRI can be particularly useful when doctors need a clearer view of certain areas, such as the brain, spinal cord, pelvis, muscles, or other soft tissues.<\/p>\nDepending on the examination, a contrast agent may be given to improve the visibility of certain abnormalities.<\/p>\n
MRI does not use X-ray radiation, but patients with certain implanted medical devices or metal objects may need special evaluation before the scan.<\/p>\n
\n- PET Scan<\/b><\/strong><\/li>\n<\/ol>\n
A PET scan for cancer<\/b><\/strong>\u00a0is a type of nuclear imaging examination that shows areas of increased metabolic activity in the body. A small amount of radioactive tracer is administered, and the scanner detects its distribution.<\/p>\nCancer cells often use more glucose than many normal cells, which can make some tumours appear as areas of increased activity on PET imaging. PET is often combined with CT to provide information about both metabolic activity and anatomical structure.<\/p>\n
PET imaging can be useful for detecting certain cancers, assessing the extent of disease, evaluating treatment response, and investigating possible recurrence.<\/p>\n
\n- Endoscopy<\/b><\/strong><\/li>\n<\/ol>\n
Endoscopy for cancer diagnosis<\/b><\/strong>\u00a0allows doctors to examine the inside of certain organs using a thin, flexible or specialised instrument equipped with a camera.<\/p>\nDepending on the suspected condition, doctors may perform procedures such as:<\/p>\n
