Burning incense may create a sweet scent, but regularly inhaling the smoke could put people at risk of cancers of the respiratory tract, researchers reported Monday
Those who used incense heavily also had higher rates of a type of cancer called squamous cell carcinoma, which refers to tumors that arise in the cells lining the internal and external surfaces of the body. The risk was seen in smokers and nonsmokers.
Study participants who used incense in their homes all day or throughout the day and night were 80 percent more likely than non-users to develop squamous cell carcinoma of the entire respiratory tract.
This only proves that too much of anything can cause problems. I already knew that.
