Cancer diagnosis
Cancer diagnosis
Cancer diagnosis (/ˈkænsər daɪəɡˈnoʊsɪs/), from the Greek words karkinos (καρκίνος, "crab") and diagnosis (διάγνωση, "knowing thoroughly"), is the process of identifying the presence and type of cancer in a patient.
Process
The process of cancer diagnosis typically begins with the patient presenting symptoms that prompt a medical examination. This may include a physical examination, blood tests, imaging tests, or a biopsy.
Physical Examination
A physical examination is often the first step in diagnosing cancer. The doctor will check for any abnormalities, such as lumps or changes in skin color.
Blood Tests
Blood tests can provide information about the overall health of the patient and whether cancer might be present. They can also be used to monitor the effectiveness of cancer treatment.
Imaging Tests
Imaging tests, such as X-rays, CT scans, and MRI scans, can help doctors visualize the inside of the body and identify any tumors or abnormalities.
Biopsy
A biopsy is a procedure in which a small sample of tissue is removed from the body and examined under a microscope. This is often the most definitive way to diagnose cancer.
Types of Cancer Diagnoses
There are many different types of cancer, each with its own methods of diagnosis. Some of the most common include breast cancer, lung cancer, prostate cancer, and colorectal cancer.
Breast Cancer
Breast cancer is often diagnosed through a combination of physical examination, mammography, and biopsy.
Lung Cancer
Lung cancer is typically diagnosed through imaging tests and biopsy.
Prostate Cancer
Prostate cancer is usually diagnosed through a combination of blood tests, physical examination, and biopsy.
Colorectal Cancer
Colorectal cancer is often diagnosed through a combination of physical examination, blood tests, imaging tests, and biopsy.
