Q/Discuss various historical theories and misconception of cancer ( pre 1890s )
With the development of science ,the Cancer theories have been changed .
the scientists proposed different historical theories over the years trying to explain cancer and its causes ,some of these theories were proven wrong and some grew more complex .These theories are :
-Humoral Theory
-Lymph Theory.
- Blastema Theory.
- Chronic Irritation Theory. -Trauma Theory.
- Parasite Theory.
which will be dis.cussed below :
*Humoral theory :
Humoral theory can also be called the theory of four different humorism. This theory was systemized by the Greek physician Hippocrates, so it could be named Hippocrates theory.
In this theory he described
the humors as different liquids within the body, these liquids or humors can be identified as blood, black bile, yellow bile and phlegm. He believed that the balance between these four humors is necessary to own healthy body and healthy mind, on the other hand if an imbalance between these liquids occurred, it will result in a biological problem in the body.The cancer as a specific disease here were thought to occurre by excess amount of black bile. So, Obviously the treatment of a disease in this theory require trying to restore the balance of the four liquids. This could be benign with focusing on dietary habits, exercise and herbal medicines. But in some cases the treatment may involve more aggressive attempts to re-gain the balance.
this theory was supported by widely trusted doctors at that time, so it held onto the middle ages it. It lasted over 1300 years.
