And the reasons people ask for citations is what you are saying is very misleading. The CDC estimates that 45% of US Adults fall into these increased risk categories. So no, it's not just people fighting off cancer it's almost half the country.
> We estimated that 45.4% of US adults are at increased risk for complications from coronavirus disease because of cardiovascular disease, diabetes, respiratory disease, hypertension, or cancer. Rates increased by age, from 19.8% for persons 18–29 years of age to 80.7% for persons >80 years of age, and varied by state, race/ethnicity, health insurance status, and employment.
none of that makes any difference. basically no one needs to disinfect masks, including those at elevated risk (emergency personnel and hospitals facing shortages the likeliest exceptions). just wear your mask at appropriate times (indoors when you can't distance from strangers for extended periods of time). regular folk don't need to do more than that.
