Lung cancer rates have decreased for Marlboro Man, but have risen steeply for nonsmokers and young women

Cat’s claw and Kalanchoe are said to help cure cancer. Or maybe for prevention.

So are literally hundreds of other things, unfortunately the evidence for this is only at the level of cells being treated, there is a huge difference from that and a treatment that is actually likely to help. Almost none of the things that work on cells end up demonstrating efficacy on animal models, and even less on clinical trials.

Passive smoking can cause lung cancer and a wide range of chemicals and fibres including glass fiber. Worked with asbestos which can take more than 20 years to show in the form of cancer. Blue asbestos is the most deadly because of its aero dynamic properties. Ratio of the fiber circumference and the length of the fiber. It can float in the air for many days.

Wearing these mask and inhaling those cotton fiber could also contribute as well to lung cancer....I get annual CT scans for my lung and heart yearly to make sure everything in good condition. A regular chest x-ray can not capture early stage 1-2 cancers as far as Im aware but the prognosis of lung cancer caught at stage 1 -2 has a better outcome than stage 3 or 4.

No, it does not. There are occupations where mask use is mandatory so people have been wearing masks all day long for many decades without any reported increase of incidence.

Viral infections on the other hand are a well characterized cause of an increase of risk for several kinds of cancer, including in the lungs.
