Tumour markers after orchidectomy: what the numbers are telling you | CION Cancer Clinics
If testicular cancer was confined to the testicle, raised AFP and hCG should fall steadily after orchidectomy and settle into the normal range. A slow fall, a plateau or a rise usually means cancer cells remain somewhere else. This page explains when the markers are checked, how to read the pattern, how seminoma and non-seminoma differ, and what these blood tests cannot tell you on their own. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Should AFP and hCG fall after orchidectomy?
If the cancer was confined to the testicle, raised AFP and hCG should fall steadily after the operation and settle back into the normal range. If they fall more slowly than expected, stop falling, or rise, it usually means some cancer cells remain elsewhere in the body.
What these blood tests are
AFP and hCG are proteins that some testicular cancers release into the blood. A third test, LDH, is less specific but is checked alongside them. Together they are called tumour markers: blood tests that give a rough signal of how much active cancer is present.
Why the timing after surgery matters
Once the testicle is removed, the body clears these proteins at a known rate. hCG clears quickly. AFP takes noticeably longer. So your team repeats the tests at set points after surgery and compares the fall with what they would expect if nothing were left behind.
Why the result feeds into staging
Staging means working out how far the cancer has spread. For testicular cancer, the marker level after surgery is part of the stage itself, along with the scan. It helps the team decide between careful watching and further treatment.
Bring the result from before surgery to every appointment. The later numbers only make sense next to it.On your blood report
What do the marker names on the report mean?
- AFP (alpha-fetoprotein)
- Made by some non-seminoma cancers. A pure seminoma does not make it, so a raised AFP changes how the tumour is classed.
- hCG or beta-hCG
- The same hormone a pregnancy test detects. It can be raised in both seminoma and non-seminoma.
- LDH
- An enzyme released by many damaged or fast-growing cells. It is a rough guide to how much disease is present, not a cancer test on its own.
- Half-life
- The time it takes for a level to halve once the source is gone. It is how the team judges whether the fall is on track.
- S stage
- A letter and number on your staging that records how high the markers were after surgery.
- Normalised
- The level has come back within the laboratory's normal range.

Ask an oncologistThe blood tests
When are the markers checked around the operation?
Before surgery
A baseline sample is taken before the testicle is removed. Without it, nobody can tell later whether a level is falling, and it is often the most useful number on the whole file.
In the days after
Repeat samples are taken over the following days and weeks. The exact timing depends on which markers were raised and on your team's protocol, so follow the dates they give you.
Before the next decision
The results are read with your CT scan and the pathology report. This is usually when the team decides between surveillance and further treatment.
During follow-up
Markers are repeated at every follow-up visit for years. A rise can be the first sign of a return, sometimes before a scan shows anything.
Reading the pattern
What can different marker patterns after surgery mean?
The pattern across several tests matters far more than any single number.
Falling on schedule to normal
This fits with the cancer having been removed with the testicle. It is encouraging, but the scan and pathology still decide the next step, because small spread can exist with normal markers.
Falling too slowly, or levelling off
This suggests cancer cells somewhere else are still making the protein. The team looks closely at the scan and usually discusses further treatment.
Rising
A true rise after surgery points to active disease. It is repeated to confirm, then acted on promptly. It is not a reason to wait for the next routine visit.
Never raised at all
Many testicular cancers, including most seminomas, never raise the markers. In that case the blood tests cannot be used to track the disease, and scans carry more of the follow-up.

How do markers differ between seminoma and non-seminoma?
Seminoma
Non-seminoma
AFP stays normal in a pure seminoma
AFP is often raised
hCG is sometimes mildly raised
hCG is often raised, sometimes very high
Markers are normal in many men
Markers are more often useful for tracking
Follow-up leans more on scans
Follow-up leans on scans and markers together
Being straight with you
What can a marker result not tell you?
A marker result is one piece of a larger picture. It cannot tell you on its own whether you will need chemotherapy, and it says nothing about your long-term outlook.
Other things can raise a marker
Liver disease can raise AFP. Some medicines and cannabis use can push hCG up slightly. LDH rises with muscle injury, heavy exercise and many common illnesses. A low-level abnormal result is usually repeated before anyone reads it as cancer.
Laboratories use different ranges
Two laboratories can report the same blood with slightly different numbers and different normal ranges. Where you can, have repeat tests done at the same laboratory, and give your team the printed reports rather than a photo of one line.
Normal markers do not rule out spread
A cancer that never made the markers will not show up in them later. This is why follow-up scans matter even when every blood test comes back normal.
If a result arrives before your appointment and worries you, call the helpline rather than waiting alone with it.Commonly believed
What do families often misunderstand about tumour markers?
"The markers are normal, so there is no need for scans."
Many testicular cancers never raise the markers. Scans pick up spread that the blood cannot. Skipping a scheduled scan because the blood looks fine is one of the commonest ways a return is found late.
"A higher number means he has less time."
The level helps with staging and planning treatment. It is not a countdown, and men with high markers are regularly treated with a good response. Ask your oncologist what the number means for the plan.
"One slightly high result means the cancer is back."
Small rises happen for many ordinary reasons, including a different laboratory. The team repeats the test and looks at the trend before drawing any conclusion.
"We can do these tests at any local lab and skip the visit."
Testing is easy. Interpreting it is the hard part. The result has to be read against the baseline, the scan and the pathology, which only your treating team has in front of them.
Questions we are asked
Common questions about tumour markers after orchidectomy
My hCG was high before surgery. Is it normal that it is still high now?
It depends on how long ago the operation was and how high it started. Markers take time to clear, and a very high starting level takes longer to come down. Your team compares the fall with the expected rate. Ask them whether your fall is on track, rather than judging a single number.
Why does AFP come down more slowly than hCG?
Each protein is cleared from the blood at its own natural speed. hCG is removed quickly. AFP lingers much longer. So a slower fall in AFP is expected and is not by itself a warning sign. What matters is whether each marker falls at the rate expected for it.
My markers were never raised. How will they follow me up?
Mainly with scans and examination, with markers still checked in case they change. This is common, especially with seminoma. It does not mean the cancer is more serious. It simply means the blood tests are less useful for tracking your particular tumour.
Do I need to fast before the marker blood test?
Usually not. AFP, hCG and LDH are not affected by a normal meal. If other tests are being taken at the same time, such as blood sugar or cholesterol, fasting may be needed for those. Check the request slip or ask the laboratory when you book.
Can the markers go up because of chemotherapy?
Sometimes, briefly, at the very start of chemotherapy, as cancer cells break down and release what they contain. This is called a surge and your oncologist expects it. It is the trend over the following cycles that shows whether treatment is working.
Will I need these blood tests for the rest of my life?
Tests are most frequent in the first years after treatment, when a return is most likely, and become less frequent after that. Your schedule depends on the cancer type, the stage and the treatment you had. Ask for your follow-up plan in writing.
Does a normal result mean the cancer is gone for good?
It is a good sign, but it is not a promise. Some cancers do not make markers, and small spread can exist with normal blood tests. That is why follow-up includes scans and why keeping every appointment matters, even when you feel completely well.
Can you look at my son's reports from another hospital?
Yes. Bring or send every marker report in date order, including the one taken before surgery, along with the scan and pathology reports. A surgical or medical oncologist can explain what the pattern shows and what questions to take back to the treating team.
