Personally I do not see the benefit of using any test like the pap test you are revering to. In contrary Many tests like the pap test can actually damage the cells which in turn can transform into cancer cells. You are better off preventing things like cancer from forming, so try to limit your intake of ultra processed foods, try to avoid sonar or any other form of artificial wave generating tech (Specifically those that go into unnatural high or low frequencies) etc.
When you have inflammation in any part of the body try to go out in the sun & go bare foot in soil, this will kill of most harmful bacteria etc. in your body & restore proper function of the body. When you have an infection you can use a mixture of extra virgin olive oil + chopped up or powdered garlic, Both are incredible at killing viruses This can be applied on the skin or eaten (Best to apply it on the skin, on & around the infection), If there is an open wound use cayenne pepper instead, this will stop bleeding, help in closing the wound, Increase blood flow & thus the temperature of the part its applied to, this can help a lot when trying to remove unwanted viruses & bacteria.
The above can help in preventing diseases like cancer, besides the above there are plenty of meditations like cleaning & vibrating that will aid in preventing & even curing it.

When you are in doubt you can always seek help from an medical expert, once you understand where the problems lie that you may be experiencing you can find cure's & remedies for it.
