4. OTHER FACTORS
* The evidence presented as regards aetiology of cancers is
no doubt, incomplete.
* There are many factors of race and geographic differences
that become apparent when cancers are studied regionally.
* It is possible the way of life and environment play a very
large part in deciding what cancers appear in great
frequency in different geographic regions.
* Some of the differences observed, in different parts of the
world are listed below:
1. There is a very low incidence of cancer of the breast
in Japan .
2. There is very low incidence of cancer of the skin in
Negroes.
3. There is high incidence of cancer of the naso- pharynx in
China .
4. There is a high incidence of primary cancer of the
liver in south and west Africa.
5. There is a high incidence of the cancer of the stomach
in Scandinavia Iceland and Japan .
There is thus reason to believe that there are other factors
which influence the incidence of cancer besides the ones
mentioned and it is also likely that more than one of the factors
may be in play in a case of cancer
may be in play in a case of cancer
