Lipomas And Vaccines
We don't know exactly what causes lipomas, it could be genetic, it could be something else. Most likely a certain kind of a two-hit model is needed. First one needs have some susceptibility to lipomas and then a secondary trigger is propably needed. A trigger might be a trauma, vaccine, drugs, menopause or similar... Perhaps it's a combination of everything?
Vaccines are also known to weaken your immune system. This happens right after the injection. Of course this should be fixed later on when the body has had time to adjust itself. But before the adjustment the body is vulnerable. There are different kinds of substances in the vaccines themselves and when the immune system is weakened the body is open to external threads as well.
Vaccines are known to cause fibrosarcomas in cats and dogs. Fibrosarcomas share some charasteristics with lipomas although sarcomas are malignant and lipomas are not.
