The doctor likely suspects that the drug <u>
Diethylstilboestrol ( thalidomide)</u>
is behind Jackie's problems</h2>

Diethylstilboestrol, commonly known as DES or thalidomide was widely prescribed as an anti-miscarriage drug for 30 years between 1943 and 1973.
The production and sale of this drug was banned due to its carcinogenic side effects. It was also discovered that the effects of this drug can also manifest themselves in people whose mothers were administered with the drug.
If Jackie's mother consumed DES while she was pregnant with Jackie,, It is probable that Jackie's miscarriages and her cancer are an indirect effect of the banned drug.
