After radiotherapy or brachytherapy, your PSA should drop to its lowest level (nadir) after 18 months to two years. Your PSA level won’t fall to zero as your healthy prostate cells will continue to produce some PSA. Your PSA level may actually rise after radiotherapy treatment, and then fall again.
Full Answer
What is a normal PSA after radiation?
The lower the PSA level at five years, the more durable the probability of maintained biochemical disease-free survival. Researchers concluded that when PSA levels remain low (less than 2 ng/mL) five years after external beam radiation therapy, the great majority of patients will be biochemically disease-free at 10 years.

What is a normal PSA level 6 months after radiation?
The median PSA 6 months after EBRT was 0.1 ng/mL (range, 0-19 ng/mL), and 310 patients (58.3%) had a 6-month PSA ≤0.1 ng/mL. Multivariable analysis (MVA) demonstrated that a 6-month post-EBRT PSA of >0.1 ng/mL was an independent predictor of worse bRFS (hazard ratio [HR] = 2.518; P<. 0001), DMFS (HR=3.743; P<.
What is a normal PSA level 3 months after radiation?
Patients were characterized by 3-month post-RT PSA values: <0.10 ng/mL, 0.10 to 0.49 ng/mL, and ≥0.50 ng/mL. The researchers found that a higher 3-month PSA level was strongly associated with biochemical progression-free survival (bPFS), prostate cancer-specific survival (PCSS), and overall survival (OS).
What are the signs that prostate cancer has spread?
Prostate cancer can spread to the lymph nodes in the groin area, or to other parts of the body. The most common symptoms are swelling and pain around the area where the cancer has spread.

Will PSA go down after radiation?

How long after radiation do you know if it worked?
For most people, the cancer experience doesn't end on the last day of radiation therapy.
