This is my theory on how propane exposure turns into Cancer.
A person getting exposed to solid propane daily will eventually cause a body addiction. Once addicted, the body starts producing cells from propane. These cells are what we known as cancer cells.
After turning propane into cancer cells, our body will start to treat and store these cancer cells like body fat. It will move these cells throughout our body, to all the main organs for storage and to maintain body functions. Our heart and lungs will depend on the propane in order to function without complications.
Once a person stops getting exposed to propane, our body will start removing/using the stored propane/cancer cells to maintain the body functions once addicted. When this happens, our body will start to leave behind tissue damage where the propane/cancer cells were stored and removed from. This process will continue over the next several months to years, once propane exposure ends. This process can also start if a person does not get enough propane in order to maintain body functions.
