Cancer

54.4K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?02:12

What is Cancer?

14.5K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Cancer Prevention02:59

Cancer Prevention

8.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Cancer Therapies

10.2K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

610
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Cancer Vaccines01:30

Cancer Vaccines

1.1K
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Summary
This summary is machine-generated.

Prostate-specific antigen (PSA) is a sensitive marker for prostate cancer diagnosis and monitoring. It aids in differential diagnosis and identifying metastatic disease, outperforming prostatic acid phosphatase.

Area of Science:

  • Oncology
  • Biochemistry
  • Immunology

Background:

  • Prostate cancer immunodiagnosis is advanced.
  • Prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) are established markers.
  • PSA is more sensitive and reliable than PAP.

Purpose of the Study:

  • To review the utility of PSA in prostate cancer management.
  • To highlight PSA's role in differential diagnosis.
  • To discuss the biological functions and potential of other prostate antigens.

Main Methods:

  • Literature review of established prostate cancer markers.
  • Analysis of PSA's clinical applications.
  • Overview of current research on novel prostate antigens.

Main Results:

  • Serum PSA is effective for monitoring disease status, predicting recurrence, and detecting residual disease.
  • PSA is valuable for histological differential diagnosis, including identifying metastatic prostate cancer.
  • PSA functions as a protease, while PAP is a phosphotyrosyl-protein phosphatase.

Conclusions:

  • PSA is a crucial tool in the clinical management of prostate cancer.
  • Further research is needed to elucidate the physiological functions of PSA and PAP.
  • Evaluation of novel prostate-specific antigens is ongoing.
