It is exception, using tobacco may be cause of cancer. If some claimed that I am using tobacco for 50 years and I have not problem of cancer. In this case situation can we declare that using tobacco is good for health. No one compete with fresh food.
Some people may not get effected of bad things, or the effects are negligible. This doesn't means that bad things will become good for others. As said above that tobacco is harmful, but it have less effect on some people. It doesn't mean that tobacco will not effect others.
It's very true because there are always some exception in whatever the basic finding is. It all depends upon the health condition of a person and generally speaking it has been found that processed meat is not a healthy diet. So, the world's oldest person is definitely an exception to the theory.
Many of these findings are still at the research stages and often inconsistent, so there is no need to panic as such since many other factors need to be considered before concluding that all cured meat is bad for health and can cause cancer ..
Nothing is absolutely harmful or useful. If this were so, people would definitely adopt healthy and discard unhealthy. Cigarette causes cancer but it is not certain that anyone who consumes cigarette will get cancer. That is why many still smoke. A man eats numeous things. Good affect of some may compensate the bad affect of harmful things. Also quantum of what you consume and how frequently or howfast also affects. Liquer is harmful. But if you dilute this well in water and consume slowly while eating non veg snacks or dry fruit, harmful affects may be reduced.

Anything done in excess is harmful. Main reason why processed meat is considered harmful is because of the additives and preservatives that are added to it. But if had in moderation, it does not make much of a difference. If people have a balanced meal comprising of cereals, pulses, vegetables , curd etc, on a regular basis then having processed meat once in a while does not matter. One should also follow the cooking instructions carefully. They are best had shallow fried or sauteed, over doing it may cause the chemicals to react. Charring of meat is unhealthy !! With a few precautions it is possible to have bacon till a ripe old age without complications but having it daily is not recommended.
@Lopamudra Your instruction filled answer is very helpful to understand how to use processed meat or by the way any processed food. In India many take chicken salami, sausage and other items quite frequently especially in winters. These are taken directly in the processed form especially for sandwiches but after reading your explanation I feel these should be sautéed or shallow fried to keep it healthy. Am I right?
