Prostata-Specific Antigen (PSA)

The PSA (Prostate-Specific Antigen) test measures the levels of PSA in the blood. PSA is a protein produced by the prostate gland and is often elevated in men with prostate cancer. However, there is an ongoing debate about the usefulness of PSA testing for prostate cancer screening and its overall accuracy and effectiveness as a diagnostic tool.

While the PSA test can detect prostate cancer early, it is not definitive and can lead to false positives or negatives. In some cases, elevated PSA levels can be caused by other conditions, such as an enlarged prostate or inflammation, rather than cancer. Additionally, some men with prostate cancer may have low PSA levels, making it difficult to detect the disease through PSA testing alone.Continue reading

What is a pathologist?

Keeping sharing simple....

As a pathologist, I am often asked what my profession entails. A pathologist is a medical doctor specializing in diagnosing diseases by examining tissue and bodily fluid samples under a microscope. Pathology is a crucial component of modern medicine as it helps doctors understand the underlying cause of a patient’s illness.

Pathologists work in a laboratory setting, analyzing samples to identify the presence and characteristics of diseases. We use a variety of techniques, such as microscopy, molecular testing, and other laboratory methods, to examine samples and make a diagnosis. Pathologists are also responsible for determining the stage and grade of cancers, which helps guide treatment decisions.

In addition to diagnosing diseases, pathologists also play an essential role in medical research. We collaborate with other medical professionals to study diseases and develop new treatments. Pathologists also oversee the quality and accuracy of laboratory tests, ensuring that results are reliable and consistent.Continue reading
