## What is an acceptable PSA velocity?

Many doctors use a PSA cutoff point of 4 ng/mL or higher when deciding if a man might need further testing, while others might recommend it starting at a lower level, such as 2.5 or 3. Most men without prostate cancer have PSA levels under 4 ng/mL of blood.

Does PSA velocity matter?

Screening for PSA Velocity Leads to Many Unnecessary Biopsies and Should Be Removed from Screening Guidelines. Researchers at Memorial Sloan Kettering Cancer Center have found that change in PSA levels over time — known as PSA velocity — is a poor predictor of prostate cancer and may lead to many unnecessary biopsies.

### What causes PSA velocity?

PSA velocity is the change in PSA levels over time. A rapid rise in PSA may indicate the presence of cancer or an aggressive form of cancer.

What is Velocity ride?

Velocity is an annual cycling event benefiting Columbia’s Herbert Irving Comprehensive Cancer Center. Learn more about how we’re joining together as one unstoppable force by riding, walking, running, or doing any activity of your choice on or before October 3, 2021 – Velocity Day.

#### What is a good PSA density score?

The study identified an optimal PSA density threshold of 0.08, with a negative predictive value of 96% for clinically significant disease. These data suggest that men with PSA density of 0.08 or less harbor a very low risk of clinically significant prostate cancer.

How is PSA velocity calculated?

PSA velocity is given in ng/ml/year and can be thought of as a prediction: for example, a patient with a current PSA of 2 ng/ml and a PSA velocity of 0.5 ng/ml/year would be expected to have a PSA of 2.5 ng/ml in 12 months time. PSA doubling time is the number of months it would take for PSA to increase two-fold.

## How fast is Rita Alton Towers?

62 mph
Rita/Max speed

Riders accelerate from 0 to 60 mph (100 km/ph) in just over 2 seconds. That’s faster than a race car! With a top speed of 100km/ph, Rita is the 5th fastest roller coaster in the UK. Riders on Rita experience a maximum G force of 4.7.

What is an abnormal PSA density?

A high PSA density means that a relatively small volume of prostate tissue is making a lot of PSA, while a low PSA density means that a large volume of prostate tissue is making relatively little PSA.
