Description:
Welcome to the PSA Calculator – risk calculator for prostate cancer.
We developed this application to inform the general public and healthcare professionals about prostate cancer.
You, a man over 40 years of age or a person with a history of prostate cancer in the family, can benefit from this application. Simple and quick, only with the result of the total PSA blood test, it is possible to know if the chances of suffering from this disease so prevalent in our environment are large or small. We provide easy-to-read information on the subject to help you understand more about the prostate and its complications as well as anatomical illustrative images related to prostate cancer.
If you are a healthcare professional you can also use the calculator results, the information area texts or the attached pictures to make important decisions, study or clarify the patient's doubts.
Here you will find up-to-date data on the subject, illustrative images about the basic anatomy and prostate cancer, and of course, a very simple calculator to use, assisting the professional in making decisions or the patient in their arguments and doubts.
The calculator evaluates PSA (Prostate Specific Antigen) data, routine examination of men over 40 or 45 years old, and expresses the likelihood of risk for prostate cancer by analyzing different conditions. When the value of free PSA is present in the exams, the analysis becomes more complete, noting that a total PSA value below 2.5 ng/ml detracts from the importance of measuring free PSA in the blood.
The calculator provides three response lines, plus the percentage value between free PSA and total PSA. In the first line the total PSA value is analyzed, probably expressing the main risk factor in question. In the second line the free PSA is evaluated and we also express its probable influence on the risk of being in the presence of a prostate cancer, as the result of the total PSA. In the third line we take into account the age of the patient to reduce or not the probabilities of problem. We take into account the tables updated in the studies on the subject: tolerance factor between age and value of total PSA.
They are straightforward answers and easy to interpret for anyone.
In the worst conditions, the need for further investigation (biopsy) at two levels will be expressed in the third response line: indicated research or strongly indicated investigation.
Blue colors represent positive or neutral points, while red colors indicate a risk or need for attention.
For better interpretation of the calculator data we suggest reading further in the application information area. The value of free PSA is not always necessary, it is most useful when the total PSA is above 2.5 or 4.0 ng/ml, it depends on the age of the man.
We look for reliable, up-to-date sources. The calculations are based on tables and statistics, but the decision to perform a biopsy is not up to the doctor, preferably a urologist.
Physical examination is essential. Other tests such as ultrasound and biopsy may be necessary for further conclusions.
The application was developed by doctors, but not just for doctors. Even you who have a relative or friend, a man over 40 or 45, can help clear up doubts or prevent complications from prostate cancer.
If in doubt, always seek qualified medical evaluation.
We are willing to exchange information and clarifications.
We accept any criticism or suggestion. The exchange of knowledge has been a valuable tool ever since.
Enjoy our work.
