If you have a compromised immune system, any vaccine can fail. By definition, you need a functional immune system to generate an immune response from any vaccine. People being treated for cancer usually have a impaired immune system from the treatment itself.
Yes, there have been "breakthrough" cases. And they fall into one of two categories:
1) They caught a cold and were forced for some reason to take that stupid 5 minute "rapid" test with the 50% failure rate that simply identifies ANY coronavirus as COVID-19.
2) They had a serious disease and an inhibited immune system, that prevented the vaccine from working.
My god, if you're under treatment for cancer, stay home! Your doctor must have warned you to not only wear a mask, but to stay home to prevent exposure to ANY infectious disease. If your immune system is compromised enough that a vaccine might not work, any minor infection could become a major medical emergency!
Yes, in your case, you need to wear a mask, regardless of whether you've received the vaccine or not, but that's got almost nothing to do with the Covid epidemic.
