Members shared varied experiences with white blood cell counts during cancer treatment, noting that WBC levels can fluctuate depending on the type of cancer, treatment stage, and whether an infection is present. Several members described how certain treatments like Ibrance can lower WBC counts, while infections or blood cancers may cause them to rise, with some recounting weekly blood work monitoring during chemotherapy that would pause treatment if counts dropped too low. A recurring theme was the importance of regular CBC testing to track these changes and the reassurance that both high and low counts can occur at different points in the cancer journey.

Sorry about yesterday's post. I didn't answer the question!!! I just went on about me. Anyway, today I will tell you what I have noticed about me (again). I'm stage 4, but am getting NO treatment right now. My white blood count is in the normal range, but on the lower side.

Can cancer cause white blood cell counts to drop?

Yes, white blood cell counts can go down when you have cancer, but it's often related to the treatments rather than the cancer itself.

Cancer can weaken your immune system, which may affect white blood cell production. However, treatments like chemotherapy are more commonly the direct cause of low white blood cell counts.

Chemotherapy targets rapidly growing cells, which includes both cancer cells and healthy cells like those in your bone marrow that produce white blood cells. This is why many people undergoing treatment need regular blood tests to monitor their blood cell levels.

Your healthcare team will likely perform complete blood counts (CBCs) throughout your treatment to check if your white blood cells, red blood cells, and platelets are at safe levels. If your counts drop too low, your doctor may adjust your treatment plan or recommend supportive care to help protect you from infections.

Low white blood cell counts can make you more vulnerable to infections, so it's important to watch for signs like fever, chills, or unusual symptoms and report them to your doctor right away.

They checked my blood work before I started anything. I had blood work done every week while I was on chemo and my targetted therapy. If my white blood cell count was low they would stop all treatment and give a shot of something to bring up my cell count hopefully then eventually restart the treatments ,some how to me it seemed counter productive to do it that way. But luckily by the grace of God that didn't happen to me. I would also think they would come up with a different treatment plan. Plus they check the other parts of that like your basophifils spelled that one wrong which is to see if you have a bacterial infection then there's another one checks for viral infections then a few more that also check your lymphocytes. I still have blood work done even now that I'm at my 4 year mark all ready. I have one coming up I think in March that's if my onocolgist appointment isn't changed again.

Your white blood count can go up and down during treatments. Normally when you have an infection, your white blood count will go up because its fighting the infection. Certain kinds of cance , like blood cancers, may case the wbc to increase. Hope this helps. Love and hugs

Huh, that's a good question. I'm going to have to go back and check mine. I'm stage 4, but because Enhertu caused inflammation in my lungs, twice, I was taken off of it 10 months ago. My doctor hasn't put me back on anything, giving my body a chance to heal. Now, I just go in every 3-4 months for CT scans. So far, nothing new has shown up.
