- Cancer Diagnosis
Most cases of
cancer are diagnosed after symptoms appear or a tumor is detected. Early
detection plays a significant role in improving the chances of recovery. Some
types of cancer can be detected early through routine self-examination, such as
breast, oral, testicular, skin, and anal cancers. In some cases, cancer may be
diagnosed incidentally when diagnosing or treating another health issue, but
this is rare.
There are
several diagnostic tests to help detect cancer, in addition to tests conducted
after diagnosis to determine the stage of cancer, its spread, the appropriate
treatment, and the expected recovery rate. Here are some common diagnostic
tests for cancer:
- Clinical Examination: The doctor performs a
thorough clinical examination to check for skin changes, lumps, tumors, or
abnormal swelling in the body.
- Laboratory Tests: Blood and urine tests help
detect disorders caused by cancer.
- Imaging Tests: There are several imaging
tests used to detect cancer, which help get accurate pictures of the
internal body parts, such as X-rays, ultrasound, CT scans, MRI, and PET
(Positron Emission Tomography).
- Biopsy: A biopsy is one of the most
accurate methods for diagnosing cancer. The doctor takes a sample from the
tissue or tumor and analyzes it in the laboratory. The method of obtaining
the sample depends on the type and location of the cancer.
