Cancer is a group of over 100 diseases where cells multiply at an uncontrollable rate. Early detection is crucial in cancer treatment. Highly advanced methods are used for cancer detection.
Visit a reputed Los Angeles clinic for cancer detection and treatment. Here is a guide to the different cancer detection methods:
High or low levels of certain substances in your body could be a sign of cancer. But this is not always reliable as some other conditions can also lead to the difference in amounts of these substances in the body. To detect if you have cancer, doctors may instruct you to take lab tests of your blood, urine, or other body fluids.
Some lab tests involve testing blood and tissue sample for the presence of tumor markers, the substances produced by cancer cells and other body cells in response to cancer. Although normal body cells also produce tumor markers, the production levels by cancer cells are much higher.
Imaging tests create pictures of the inside of your body. These pictures can help doctors can find out the location of tumors if any. The images are created by the following methods:
In CT (Computerized tomography) scan, a series of pictures of your internal organs are taken from different angles. These images are then used to create 3D images of the inside of your body.
In an MRI (Magnetic Resonance Imaging), the pictures of your body are taken in slices making use of a powerful magnet and radio waves. The detailed images of the inside of your body are developed from these slices.
Also called a radionucleotide scan, a nuclear scan takes pictures of the inside of the body using radioactive material.
The radioactive material used in your body to take pictures will gradually lose its radioactivity and leaves the body through feces and urine.
An ultrasound scan uses high energy ultrasound waves that are beyond the upper limit of the human audible range. When the ultrasound waves are passed into your body, they echo off the body tissues and the echoes are collected by a computer to create pictures of the inside of the body.
A biopsy is the most reliable cancer diagnosis method. In most cases, the doctor relies on this diagnosis method to detect cancer. The doctor removes a sample of the tissue from the body of the person. The pathologist then studies the tissue under a microscope and also run other tests to find out if it is cancer.
If the diagnostic tests confirm that you have cancer, you have to start taking treatment without any delay.
