Liver cancer rates have increased by 600 per cent in the same period. 

If medical science is telling us the truth, why are these rates ballooning while other cancers, such as stomach or bladder cancer, are declining?

The answer may lie in the animal testing of the contraceptive pill, where multiple species exhibited large increases in four different cancers, including breast and liver cancer. 

Manufacturers were quick to claim that these results did not apply to human users or that studies were inconclusive.

This seemed questionable, as a former hormonal drug, DES, had been removed from sale because of high cancer rates in users and especially their daughters. 

DES began to be prescribed in 1938. The 1940s are considered the beginning of the increase in breast cancer, as well as the decline in male sperm counts.

As contraceptive usage grew, 18 studies of Pill users showed breast cancer increases ranging from 190 per cent to 600 per cent. 

Amazingly, for each of these studies there were two claiming opposing results. 

No one seems to have questioned the reasons for these wide discrepancies in scientific analyses. 

Today we use a meta-analysis of all 54 studies, averaging the increases with the decreases, giving only a 40 per cent increase in breast cancer.

When the contraceptive pill was illegal in Japan, only 1 in 50 women experienced breast cancer; at that time in Australia it was 1 in 10. 

In 2005, WHO oncologists declared the contraceptive pill a class-one carcinogen and we have stern restrictions for others, like smoking and asbestos. 

Is our duty of care to consumers being neglected?
