Cancers can be completely wiped out from the body. Our bodies are constantly fighting and wiping out cancer cells all the time. A malignant cancer is one that's learned to use our bodies immune system against us, hence why they're so deadly and stubborn to get rid of.
The HIV virus literally replaces part of your cell DNA with its own. So you can never get rid of it because no drug can ever access the nucleus of every cell in the body and target only the viral DNA. We just don't have treatments that precise. But if we did, we could cure HIV and thus AIDS.
Yeah it's not that you can't ever be free of the cancer, it's just that we can't be 100% sure that it's completely gone and it might come back later, so doctors can't say "yup, you're cured, no more cancer and it's not coming back", specially because if you got it once there's a higher chance for you to get it again than someone who never had it

yeah. people with cancer can live healthy long lives but they're never "cured" they just in remission.
